Airway Management Techniques for Maintaining Open Airways

Airway management keeps a person's breathing path clear and safe. This is crucial in medical situations when someone can't breathe well on their own. By using various methods and tools, healthcare professionals ensure that enough air reaches the lungs, letting the body get the oxygen it needs. In this article, we'll explore the basics of airway management and the different techniques to establish a patent airway during life threatening situations.

Airway management serves as to a set of interventions used to establish and maintain a clear and unobstructed airway. Below is a list of Airway Management techniques that can be used to open the airway and ensure optimal oxygenation and ventilation.


  • Head-Tilt-Chin-Lift: One fundamental technique is the Head-Tilt-Chin-Lift. It's like gently tilting the head back and lifting the chin up. This helps open the airway by moving the tongue away from the back of the throat. It's commonly for unconscious patients.
  • Jaw thrust: Another method is the jaw thrust. Instead of tilting the head, this technique involves using your fingers to gently lift the jaw without moving the head. It's often used when there's a concern about potential neck injuries.
  • Oropharyngeal Airway: This is a curved plastic device that is placed into the mouth to keep the tongue away from the back of the throat. It's useful when a person can't maintain their airway on their own, such as during anesthesia or unconsciousness.
  • Nasopharyngeal Airway: This flexible tube is inserted through the nose down into the throat. It helps keep the airway open and is often used when the mouth can't be used, like in cases of facial injuries.
  • Endotracheal Tubes: These tubes are put into the windpipe through the mouth or nose. They're used when a person can't breathe on their own or needs help breathing. They're commonly used during surgeries and in critical care settings.
  • Supraglottic Airways: These are devices placed into the throat above the vocal cords to create an airway passage. They're used when inserting a breathing tube into the trachea is challenging or impossible. They're helpful in emergencies.
  • Cricothyrotomy and Tracheostomy: These involve creating a hole directly in the neck into the trachea to establish an airway. They're last-resort options used when other methods can't work.



The Head-Tilt-Chin-Lift technique is one of the most basic yet crucial methods in airway management. Imagine you're gently tilting a person's head backward while lifting their chin upward. This seemingly simple action actually serves a critical purpose – it helps to align the airway by moving the tongue away from the back of the throat. This method is typically employed when dealing with unconscious patients, as it's often enough to open up their airways and allow for unobstructed breathing.


Jaw thrust

When there's a concern about potential neck injuries, like in accidents or trauma cases, the Jaw thrust technique comes into play. Instead of tilting the head, this method involves using your fingers to gently lift the jaw upward without moving the head. By doing so, the airway is similarly cleared and opened up, ensuring that the air passage remains unrestricted while minimizing any potential damage to the neck area.


Oropharyngeal Airway

The Oropharyngeal Airway, a critical tool in airway management, is a curved, rigid plastic device designed for oral insertion. Its primary function is to prevent the tongue from obstructing the airway by maintaining a clear passage. This device is vital in situations where individuals, such as those under anesthesia or in an unconscious state, are unable to maintain a patent airway independently. The oropharyngeal airway's insertion technique requires careful handling to avoid triggering the gag reflex, making it suitable primarily for unconscious patients. It plays a crucial role in ensuring uninterrupted airflow and facilitating effective ventilation during emergency respiratory management.


Nasopharyngeal Airway

In scenarios where utilizing the mouth is impractical, such as when the mouth is injured or needs to be used for other medical interventions, the Nasopharyngeal Airway steps in. This is a flexible tube that's inserted through the nose and extends down into the throat. By creating an alternative pathway, this technique helps prevent the tongue and other soft tissues from obstructing the airway, ensuring that adequate airflow is maintained.


Endotracheal Tubes

Endotracheal Tubes are essential when a person cannot breathe effectively on their own or requires assistance with breathing. These tubes are inserted either through the mouth or nose and advanced into the trachea, also known as the windpipe. They create a direct and secure path for air to travel into the lungs. Commonly used during surgeries or in critical care scenarios, these tubes allow healthcare professionals to control ventilation and oxygenation more directly.

How do you perform endotracheal intubation, and what are its risks?

Endotracheal intubation involves inserting a tube through the vocal cords into the trachea. This can be achieved using direct laryngoscopy or video laryngoscopy. Risks include accidentally placing the tube in the esophagus (esophageal intubation), potential dental trauma during insertion, the occurrence of laryngospasm, and the possibility of damage to the vocal cords.


Supraglottic Airways

When traditional methods of airway management face challenges, Supraglottic Airways comes into play. These devices are inserted through the mouth and positioned above the vocal cords, establishing an airway passage without the need for direct access to the trachea. They're particularly valuable in emergency situations or when inserting a breathing tube into the trachea is not feasible or appropriate.

How do supraglottic airway devices differ from endotracheal tubes?

Supraglottic airway devices, like the laryngeal mask airway (LMA), sit above the glottis, providing a seal around the laryngeal inlet. These devices are often used in situations where endotracheal intubation may be challenging or unnecessary. Endotracheal tubes, on the other hand, pass through the vocal cords into the trachea, securing the airway more invasively.

What are the different types of laryngoscopes and their uses?

Laryngoscopes come in various types, with the Macintosh and Miller blades being common. The Macintosh blade is typically preferred for routine intubations due to its curved design, while the Miller blade, with its straight design, is useful in patients with limited mouth opening or challenging airway anatomy.


Cricothyrotomy and Tracheostomy

In the most severe cases, when all other methods fail to establish or maintain an airway, the last-resort options of Cricothyrotomy and Tracheostomy may be considered. These procedures involve creating an opening directly in the neck and into the trachea. A Cricothyrotomy involves making an incision through the cricothyroid membrane, while a Tracheostomy is a surgical procedure that creates a more permanent opening lower down in the neck. These techniques are extreme measures used when there's a critical need for oxygenation and ventilation and other options have been exhausted.

What are the fundamental steps in basic airway management?

  1. Assessment: This involves a comprehensive evaluation of the patient's mental status, respiratory rate, and overall condition. Understanding the patient's medical history, especially any pre-existing respiratory conditions, aids in decision-making.
  2. Positioning: Proper positioning is critical to ensure a patent airway. The head-tilt-chin-lift or jaw-thrust maneuvers help align the airway, facilitating effective ventilation.
  3. Clearing Obstructions: Quickly identifying and removing any visible obstructions, such as foreign objects or fluids, is crucial. This may involve manual techniques or suction devices.
  4. Basic Airways: Oropharyngeal or nasopharyngeal airways are inserted to maintain a clear passage for air to flow. Oxygen support is provided as needed to improve oxygenation.

What are the indications for advanced airway management like intubation?

Advanced airway management is warranted in scenarios where the patient's respiratory function is compromised. This includes conditions like respiratory failure (characterized by hypoxia or hypercapnia), an inability to protect the airway due to altered mental status or unconsciousness, the presence of an upper airway obstruction, and situations requiring controlled ventilation and airway protection.

Understanding Basic Life Support

Basic Life Support (BLS) is a fundamental cornerstone in emergency medical care, with its key components crucial for saving lives. At its core, BLS is about providing immediate and essential assistance to individuals facing life-threatening situations. Central to BLS is the significance of proper airway management, which stands as a foundational skill in this life-saving practice.

Maintaining a clear and unobstructed airway is paramount, as it ensures that oxygen can flow into the lungs and reach vital organs. This is particularly critical when someone's breathing or heart function has been compromised. BLS encompasses various techniques, including the Head-Tilt-Chin-Lift and Jaw-Thrust methods, aimed at ensuring that the airway remains open.

Additionally, understanding how to use tools like oropharyngeal and nasopharyngeal airways, endotracheal tubes, and supraglottic airways plays a pivotal role in successful BLS. With these skills, healthcare providers and first responders can swiftly respond to emergencies, administer life-saving interventions, and significantly improve the chances of survival for those in need.


Anatomy of the Airway

The airway consists of a complex network of structures responsible for enabling the passage of air into and out of the lungs, facilitating the process of breathing. The upper airway comprises the nasal passages, mouth, throat (pharynx), and voice box (larynx). The lower airway includes the trachea (windpipe), bronchi, and bronchioles. During inhalation, air enters through the nose or mouth, travels down the throat, and enters the trachea. From there, it branches into the bronchi, reaching the lungs, where oxygen is exchanged for carbon dioxide in the blood. However, this intricate system can face potential points of obstruction.

  • The tongue can fall back and block the airway, especially when a person is unconscious, or their muscles relax.
  • Swelling of the throat due to allergic reactions, infections, or trauma can narrow the air passage.
  • Foreign objects, such as food or small items, might inadvertently enter the airway and disrupt the airflow. 
  • Injuries or medical conditions that cause the tissues of the throat to collapse can also lead to blockages.


Airway obstructions impede the vital flow of oxygen, stressing the importance of effective airway management techniques like the Head-Tilt-Chin-Lift and Jaw-Thrust, as well as utilizing airway devices to swiftly address these issues and ensure uninterrupted breathing.


In what situations is airway management necessary in basic life support?

Airway management is a critical component of Basic Life Support that becomes necessary in various life-threatening situations. Ensuring a clear and unobstructed airway is essential to maintain adequate breathing and oxygenation. Here are some situations where airway management plays a crucial role in BLS:

  • Unconsciousness
  • Cardiac Arrest
  • Drowning or Near-Drowning
  • Choking
  • Respiratory Distress
  • Drug Overdose
  • Trauma
  • Seizures



When a person becomes unconscious, their muscles may relax, including those that help keep the airway open. This can lead to the tongue obstructing the airway or the soft tissues of the throat collapsing, causing a blockage. Without intervention, the obstruction can prevent air from entering the lungs, leading to a lack of oxygen. Airway management in this scenario is critical to ensure the airway remains open and unobstructed. Techniques like the Head-Tilt-Chin-Lift or Jaw-Thrust are employed to adjust the head and jaw position, allowing the air passage to remain clear and enabling adequate breathing.


Cardiac Arrest

During a cardiac arrest, the heart ceases its pumping action, and with it, breathing may stop as well. Effective airway management becomes crucial to provide rescue breaths and maintain oxygen flow to the lungs and body. Techniques such as mouth-to-mouth ventilation or bag mask ventilation are employed to administer artificial breaths. By delivering oxygen-rich air to the lungs, airway management supports the body's oxygen needs, aiding in the overall resuscitation effort.


Drowning or Near-Drowning

In cases of drowning or near-drowning incidents, water can enter the airway, causing immediate distress. Water inhalation can obstruct the airway or lead to inflammation that further narrows the passage. Airway management is focused on removing any water from the airway and ensuring its unobstructed nature. Swift action is taken to position the person's head and clear any foreign matter to allow for effective breathing and oxygen exchange.



Choking occurs when a foreign object obstructs the airway, preventing air from freely entering the lungs. This situation can escalate quickly, leading to serious oxygen deprivation. Airway management involves rapid interventions, like the Heimlich maneuver, to dislodge the obstructing object and restore the airflow. Timely and proper execution of these techniques can prevent further complications and restore normal breathing.


Respiratory Distress

In cases of severe respiratory distress, often triggered by conditions such as allergic reactions or asthma attacks, the airway's functionality is compromised. Airway management focuses on addressing the underlying cause while maintaining a clear passage for air. This can involve administering medications to alleviate the distress and positioning the person to ensure unobstructed breathing.


Drug Overdose

Certain drugs or substances can depress the central nervous system, causing a person's breathing to slow down or stop entirely. Airway management is vital to ensure that the airway remains clear and unobstructed, even if the person's natural drive to breathe is diminished. By providing artificial respiration and maintaining proper oxygenation, airway management can counteract the effects of the overdose.



Severe head or facial trauma, such as head injuries or fractures, can result in swelling, bleeding, or structural displacement obstructing the airway. Airway management in traumatic situations involves careful immobilization of the head and neck, along with measures to clear and secure the airway. These actions are aimed at preventing further damage and ensuring the person can breathe freely.



During a seizure, a person's muscle movements can inadvertently impact their airway, leading to temporary obstruction. Once the seizure subsides, airway management may be necessary to ensure the air passage remains clear and the person can breathe normally again. This precaution prevents potential complications arising from post-seizure muscle relaxation.

What are the signs of Airway Obstruction?

Signs of airway obstruction can vary in severity and may include:

  1. Difficulty Breathing: The person may exhibit labored breathing, rapid breathing, or gasping for air.
  2. Noisy Breathing: Stridor, a high-pitched sound during inhalation, or gurgling sounds may indicate partial obstruction.
  3. Inability to Speak: The person might not be able to speak or communicate due to limited airflow.
  4. Coughing or Wheezing: Persistent coughing, wheezing, or choking sounds could signify an obstructed airway.
  5. Bluish Skin: Cyanosis, a bluish tint on the lips, fingers, or face, might occur due to lack of oxygen.
  6. Clutching Throat: The person might grab their throat or show signs of panic, indicating a blockage.
  7. Ineffective Cough: Coughing without relief from the obstruction might be seen.
  8. Loss of Consciousness: A severe obstruction can lead to unconsciousness.
  9. No Breathing: In extreme cases, complete airway blockage can result in no breathing.
  10. Unable to Swallow or Speak: Difficulty swallowing saliva or inability to speak might indicate an obstruction.

How do you evaluate a patient’s risk for difficult airway management?

To evaluate a patient's risk for difficult airway management, consider factors such as the patient's medical history, previous difficult airway incidents, limited mouth opening, reduced neck mobility, and any facial trauma. These indicators help anticipate challenges and plan accordingly.

How is airway management performed in trauma patients?

Airway management in trauma patients requires special considerations. Stabilizing the cervical spine is paramount to prevent further injury. Rapid sequence intubation may be necessary, and clinicians should be mindful of potential injuries that could complicate airway management.

What are the unique challenges in airway management for pediatric patients?

Challenges include smaller airways, different anatomy, and the need for age-appropriate equipment and techniques.

  • Smaller Airways: Pediatric patients have narrower airways, which can make intubation and ventilation more challenging. This requires precision and careful selection of appropriately sized equipment to avoid trauma and ensure an effective seal.
  • Different Anatomy: The anatomy of a child's airway is distinct from that of adults. For example, the larynx is positioned higher, and the epiglottis is more omega-shaped and floppy. These anatomical differences require adjustments in intubation techniques to navigate the unique structures.
  • Higher Oxygen Consumption: Pediatric patients have a higher basal metabolic rate and oxygen consumption compared to adults. Ensuring adequate oxygenation is critical, especially during procedures that may interrupt normal respiratory function.
  • Age-Related Variation: The challenges in pediatric airway management vary with the age of the child. Neonates, infants, and older children each present unique considerations, requiring healthcare providers to adapt their approach based on the specific age group.
  • Limited Physiological Reserves: Pediatric patients may have limited physiological reserves, meaning they can deteriorate rapidly if there is a delay or difficulty in establishing a secure airway. This emphasizes the need for swift and efficient airway management in this population.
  • Equipment Size and Selection: Choosing the right-sized equipment is essential. Pediatric laryngoscopes, endotracheal tubes, and supraglottic airway devices should be selected based on the child's age, weight, and developmental stage to minimize trauma and optimize ventilation.


What should be monitored during the process of airway management?

One of the primary aspects to monitor is the person's breathing. Regularly assess whether the chest rises and falls with each rescue breath, indicating successful ventilation. Skin color is another critical indicator – watch for any signs of cyanosis, a bluish tint, which can signal inadequate oxygenation. Auditory cues like stridor (high-pitched sound), wheezing, or gurgling sounds can provide insight into airway patency. The person's responsiveness should be continuously evaluated to adapt airway maneuvers if necessary. This comprehensive monitoring ensures that appropriate interventions are applied promptly, adjusting to the person's changing condition.


How to manage the airway amidst complications such as vomiting or bleeding?

If vomiting occurs, gently turning the person onto their side, known as the recovery position, can prevent aspiration by allowing fluids to drain. This action is followed by clearing the airway before resuming airway management.

In cases of bleeding, controlling the bleeding while maintaining the airway's integrity is critical. Suction might be employed to clear blood from the airway and ensure proper oxygen exchange.


What is the most effective method of airway management?

For someone who is unconscious and without suspected neck injuries, the Head-Tilt-Chin-Lift technique is often effective in opening the airway. If there's concern about neck injuries, the Jaw-Thrust technique should be employed to minimize neck movement.

In cases where a person can't maintain their airway on their own due to muscle relaxation, using airway adjuncts like oropharyngeal or nasopharyngeal airways might be necessary to prevent obstruction.

For individuals in cardiac arrest or those not breathing, effective ventilation techniques, including mouth-to-mouth, bag-mask ventilation, or advanced airway devices like endotracheal tubes, laryngeal mask airway or supraglottic airways, are crucial to provide oxygen and ensure proper ventilation.

Ultimately, the effectiveness of airway management lies in the hands of properly trained healthcare providers and rescuers who can assess the situation and select the most appropriate method based on the individual's condition and the available resources.

What are the essential skills needed for effective airway management?

The essential skills needed for effective airway management include knowledge of anatomy, proficiency in basic and advanced airway techniques, and effective communication and teamwork.

  • Anatomy and Physiology Knowledge: Understanding the anatomy of the airway and respiratory system is fundamental for effective airway management.
  • Technical Proficiency: Proficient use of airway adjuncts, equipment, and techniques, including intubation and ventilation, is essential.
  • Communication and Teamwork: Clear communication within the healthcare team is crucial for coordinated and successful airway interventions.
  • Problem-solving Ability: Rapid decision-making skills are necessary to adapt to unexpected challenges during airway management scenarios.

How is competency in airway management maintained and assessed?

Competency is maintained through regular training sessions, simulations, participation in workshops, and continuous medical education.

  • Regular Training Sessions: Healthcare professionals participate in regular training sessions, including simulations and skill labs, to reinforce and update their airway management skills.
  • Workshops and Courses: Attending workshops and courses specific to airway management ensures ongoing education and exposure to the latest techniques.
  • Continuous Medical Education: Engaging in continuous medical education through conferences, webinars, and literature review helps clinicians stay informed about advancements in airway management.

What are the common medications used during airway management?

Common medications used during airway management include sedatives (propofol, midazolam) for inducing a state of sleep or relaxation, reducing anxiety and facilitating procedures like intubation. Muscle Relaxants such as Rocuronium and Succinylcholine is also utilized paralyze skeletal muscles, including those involved in respiration, to facilitate intubation and improve airway control.

What are the common complications of airway management?

Common complications of airway management include esophageal intubation, aspiration, dental trauma, and hypoxia during intubation attempts.

  • Esophageal Intubation: Incorrect placement of the endotracheal tube in the esophagus instead of the trachea. Continuous monitoring and confirmation techniques, such as capnography, help prevent and promptly identify esophageal intubation.
  • Aspiration: Inhalation of gastric contents into the lungs, potentially leading to pneumonia. Precautions, such as fasting before procedures, use of rapid sequence intubation, and proper patient positioning, can mitigate the risk of aspiration.
  • Dental Trauma: Injury to teeth or surrounding structures during intubation attempts. Careful examination of the oral cavity, proper technique, and the use of adjuncts like stylets can minimize the risk of dental trauma.
  • Hypoxia during Intubation Attempts: Reduced oxygen levels during the intubation process. Swift and efficient intubation techniques, pre-oxygenation, and continuous monitoring help manage and prevent hypoxia.

How do you manage a 'cannot intubate, cannot oxygenate' (CICO) scenario?

In situations where traditional methods of intubation fail and ventilation cannot be achieved, emergency front-of-neck access (cricothyroidotomy) is initiated. This involves making a surgical airway through the cricothyroid membrane, allowing for the insertion of a tube directly into the trachea, ensuring a secure airway for oxygenation and ventilation.

How do protocols vary for airway management in the operating room versus the emergency department?

Airway management protocols vary between the operating room (OR) and the emergency department (ED). In the OR, the focus is on controlled intubation, with thorough preoperative assessments and optimized conditions. Muscle relaxants are commonly used, and interventions are planned based on patient characteristics and the nature of the surgery. Continuous monitoring ensures ongoing assessment.

Conversely, in the ED, protocols prioritize rapid intervention due to urgent situations. The emphasis is on urgent airway assessments, limited preparation time, and adaptability in techniques. Supraglottic devices may be favored, and efficient teamwork is critical. Ongoing reassessment is integral in the dynamic ED environment. The differing priorities reflect the distinct demands of elective surgeries in the OR versus the urgent nature of emergency scenarios in the ED.

What are the recent advances in airway management techniques and tools?
