This article will provide an in-depth exploration of rescue breathing, covering its fundamental aspects, including its purpose, step-by-step procedures, and the critical role it plays in sustaining life until professional medical assistance arrives.
Before initiating rescue breathing, it's vital to ensure safety for both the rescuer and the victim. The steps include checking for airway obstruction and recognizing breathing difficulties.
Checking Airway Obstructions
Checking for airway obstructions is a necessary step before performing rescue breathing. If the airway is blocked, rescue breaths will not reach the lungs. This is why CPR certification includes training on how to clear the airway.
To check for airway obstructions, position the victim on their back, open the airway using the "head-tilt, chin-lift" technique, and clear visible obstructions if present. Caution should be exercised in case of suspected neck or spine injuries.
Recognizing Breathing Difficulties
Recognizing breathing difficulties in a victim is a critical skill in CPR. It helps the rescuer identify when to start rescue breathing. When assessing breathing difficulties, closely observe the victim's chest movement, listen for breathing sounds, and feel for exhaled air for no more than 10 seconds. Abnormal signs such as gasping or shallow breathing indicate the need for immediate assistance. This skill is also taught in CPR certification courses through various scenarios and symptoms.
Adapting to Different Victim Sizes
Adapting rescue breathing techniques to different victim sizes and special circumstances is crucial in providing effective first aid. This adaptability is taught in comprehensive CPR certification courses. Here's a guide on how to adapt rescue breathing to different victim sizes and special circumstances:
Adult Rescue Breathing
For adult victims, the following steps can be followed:
1. Check the scene: Ensure the area is safe for both you and the victim before proceeding.
2. Check responsiveness: Tap the victim and shout loudly to check if they respond. If there is no response and the victim is not breathing or breathing abnormally, continue to the next step.
3. Call for help: Call emergency services immediately or instruct someone nearby to call for help.
4. Head-tilt, chin-lift: Gently tilt the victim's head backward and lift their chin to open the airway.
5. Pinch nose, give breaths: Pinch the victim's nose shut, take a deep breath, and give a slow breath into the victim's mouth, making sure their chest rises. Repeat this process for one breath every 5 to 6 seconds.
6. Continue rescue breathing until the victim starts breathing on their own or until medical help arrives.
Child Rescue Breathing
For children, follow a similar approach with a few adjustments:
1. Check the scene and responsiveness as before.
2. Head-tilt, chin-lift: Perform a head-tilt and chin-lift, but be cautious not to tilt the head too far back as it may block the airway in small children.
3. Give gentle breaths: Give gentle breaths into the child's mouth, ensuring their chest rises with each breath. Use less force compared to adult rescue breathing.
4. Continue until help arrives or the child starts breathing on their own.
Infant Rescue Breathing
For infants (children under one year old), adapt the technique further:
1. Check the scene and responsiveness as usual.
2. Head-tilt, chin-lift: Use a modified head-tilt and chin-lift technique, making sure not to overextend the neck.
3. Cover both nose and mouth: For infants, it's essential to cover both their nose and mouth with your mouth to provide effective breaths. Ensure a good seal.
4. Give small, gentle breaths: Provide small, gentle breaths to the infant's mouth and nose, making sure their chest rises visibly.
5. Continue until help arrives or the infant starts breathing on their own.
Rescue breathing in special circumstances
In special circumstances like drowning or drug overdose, some additional considerations apply:
- Drowning: If the victim has been rescued from drowning, remove them from the water, and check responsiveness. Perform rescue breathing immediately if they are not breathing. Water in the lungs can impair gas exchange, making rescue breathing crucial in such cases.
- Drug Overdose: In the case of a drug overdose, if the victim is unconscious and not breathing, call for help immediately. Be cautious while providing rescue breaths, as the presence of harmful substances in their mouth might put the rescuer at risk. Consider using a CPR face shield or pocket mask with a one-way valve for added protection.

What is Rescue Breathing?
Rescue breathing, also known as mouth-to-mouth resuscitation or artificial respiration, is a life-saving first aid technique used to restore breathing in individuals who have stopped breathing or are experiencing breathing difficulties. It is typically performed in emergency situations such as drowning, suffocation, or cardiac arrest, where the person's ability to breathe on their own has been compromised.
History and Evolution of Rescue Breathing
The origins of rescue breathing can be traced back to ancient civilizations where early forms of resuscitation were attempted. Historical records suggest that the ancient Egyptians, as early as 3000 BCE, employed mouth-to-mouth resuscitation by using a reed to blow air into the nostrils of a drowning victim.
However, the modern concept of rescue breathing and its evolution began to take shape during the 18th and 19th centuries. It was in the 18th century that the Society for the Recovery of Drowned Persons was established in England, emphasizing the importance of rescue techniques for drowning victims. This led to the development of more organized approaches to resuscitation, particularly for individuals found unconscious in the water.
- Early 20th century: Dr. George Crile demonstrates closed-chest cardiac massage, a precursor to modern CPR, involving manual chest compressions for circulation aid.
- 1960s: Dr. Peter Safar and Dr. James Elam establish chest compressions and rescue breathing as the foundation of modern CPR.
- Mouth-to-mouth resuscitation gains recognition for maintaining oxygenation during CPR.
- "ABCs of resuscitation" (Airway, Breathing, Circulation) promoted by organizations like the American Heart Association, leading to standardized resuscitation techniques.
- The latter half of the 20th century: The introduction of pocket masks and bag-valve masks improves ventilation efficiency and safety during Cardiopulmonary Resuscitation.
The Role of Rescue Breathing in the Chain of Survival
The role of rescue breathing primarily falls within the second link of the Chain of Survival, "Early CPR." When a person experiences cardiac arrest, their heart stops pumping effectively, leading to a lack of oxygen supply to the brain and other organs. This is a dire medical emergency, and immediate CPR, which includes both chest compressions and rescue breathing, becomes a lifeline.
While chest compressions help maintain blood circulation, rescue breathing provides a continuous supply of life-sustaining oxygen to the victim's lungs and bloodstream. This oxygen is essential for cellular metabolism and preventing irreversible brain and organ damage until the heart can be restarted, or advanced medical care can be provided.
Timely and effective rescue breathing is vital in saving lives because it serves as a bridge until defibrillation or advanced medical help arrives. The brain can only survive for a short period without oxygen, and every second counts in these critical situations. Rescue breathing buys precious time, increasing the likelihood of successful resuscitation and a positive outcome.
For untrained bystanders, hands-only CPR (chest compressions without rescue breaths) can still be a valuable option, as it maintains blood flow. However, when trained rescuers are present, combining rescue breathing with chest compressions becomes the most effective approach, further maximizing the chances of survival.
How does rescue breathing differ from CPR?
Rescue breathing and CPR are vital life-saving interventions employed in emergencies. Rescue breathing concentrates on reestablishing breathing by delivering direct breaths into the person's lungs. In contrast, CPR integrates rescue breathing with chest compressions, addressing both breathing and circulation during cardiac arrest. Depending on the situation, rescue breaths can be administered independently or as an integral part of CPR.
When and in what types of emergencies is rescue breathing used?
Rescue breathing is used in specific emergency situations where a person is not breathing adequately or has completely stopped breathing. Common scenarios where rescue breathing is employed include:
- Cardiac Arrest: When a person's heart stops beating effectively, leading to a lack of pulse and breathing.
- Drowning: In cases where someone has been submerged in water and has subsequently stopped breathing.
- Suffocation: When a person's airway is blocked, preventing them from breathing.
- Drug Overdose: In situations where drug use has caused respiratory depression or stopped the person from breathing.
- Choking: When a foreign object obstructs the airway, causing difficulty or cessation of breathing.
- Electric Shock: In severe cases of electrical accidents, which may result in respiratory distress or arrest.
- Anaphylaxis: In severe allergic reactions, where swelling of the airways may cause difficulty in breathing or respiratory arrest.
- Near-drowning: Even if a person appears fine after a near-drowning incident, they may still need rescue breathing due to water inhalation.
- Carbon Monoxide Poisoning: In cases of carbon monoxide exposure, which can lead to oxygen deprivation and respiratory distress.
Understanding Breathing Rates
Rescue breathing rates refer to the number of breaths delivered to a person in need of artificial respiration during a rescue situation, such as in cases of cardiac arrest or respiratory distress. The rate at which rescue breaths are administered is a crucial aspect of the technique, as it ensures a sufficient supply of oxygen to the person's lungs while maintaining effective chest compressions in CPR.
The rate of rescue breaths may vary depending on the person's size, age, and specific emergency. However, the general guideline is to deliver one rescue breath every 5 to 6 seconds, which equates to around 10 to 12 breaths per minute.
Till what point should rescue breathing be administered to an unconscious person?
Rescue breathing should be administered on an unconscious person until one of the following conditions is met:
- The person starts breathing spontaneously
- Professional medical help arrives
- Signs of life and consciousness return
- The rescuer becomes too exhausted
- Definitive signs of death are present
What are the signs that Rescue Breathing is effective?
Effective rescue breathing is indicated by the rise and fall of the victim's chest with each breath, improved skin color, increased and regular breathing rate, responsiveness or regaining consciousness, and possibly restored pulse and circulation. Positive feedback from bystanders may also confirm its effectiveness.
Post-rescue breathing care for the victim
Post-rescue breathing care involves continuous monitoring of the victim's vital signs, detecting respiratory distress recurrence, and addressing potential complications. It aims to ensure the victim's well-being, early detection of complications, and psychological recovery. Seeking immediate medical assistance, administering supplemental oxygen if available, and providing emotional support are essential steps to ensure comprehensive evaluation and treatment.
Myths and Misconceptions about Rescue Breathing
Rescue breathing is a critical skill in providing emergency medical care, but it is also subject to several myths and misconceptions. It's essential to debunk these misconceptions to ensure that rescuers have accurate information and can provide effective assistance. Some common myths and misconceptions about rescue breathing include:
- Rescue Breathing Can Restart the Heart: One of the most common misconceptions is that rescue breathing alone can restart a stopped heart. In reality, rescue breathing provides oxygen to the lungs, but it does not address the absence of a heartbeat. For cardiac arrest cases, CPR, which combines chest compressions with rescue breaths, is required to maintain blood circulation.
- Rescue Breathing Should Only Be Done Mouth-to-Mouth: While traditional mouth-to-mouth rescue breathing is a widely known method, it is not the only option. Pocket masks or face shields with one-way valves can provide a barrier and protect the rescuer while delivering rescue breaths. Mouth-to-nose resuscitation is also a viable alternative in certain situations.
- You Should Blow Hard During Rescue Breathing: Excessive force during rescue breathing is unnecessary and may lead to complications. Gentle, controlled breaths are sufficient to inflate the victim's lungs without causing harm.
- Rescue Breathing Can Transmit Diseases Easily: The risk of disease transmission during rescue breathing is generally low. The chances of transmission can be further reduced by using pocket masks or face shields with one-way valves.
- Rescue Breathing Is Not Necessary for Children or Infants: Some people mistakenly believe that rescue breathing is not required for children or infants because their oxygen demands are lower. In reality, rescue breathing is essential for any non-breathing victim, regardless of age.
- Rescue Breathing Is Only for Drowning Victims: While rescue breathing is commonly associated with drowning victims, it is applicable to any situation where a person is not breathing or has inadequate breathing, such as drug overdoses, choking, or respiratory emergencies.
- Rescue Breathing Is a Last Resort: Rescue breathing should be initiated promptly when someone is unresponsive and not breathing effectively. Waiting for a last resort delays essential oxygen support and can worsen the victim's condition.
- Rescue Breathing Always Restores Consciousness: While effective rescue breathing can lead to the victim regaining consciousness, it is not a guarantee. The underlying cause of the unconsciousness must be addressed, and professional medical help should be sought.
- Rescue Breathing Is Only for Healthcare Professionals: Rescue breathing is a skill that can be taught to laypersons and non-medical professionals. Basic life support training can enable anyone to provide rescue breaths effectively.
It is essential to receive proper training and education in first aid and CPR, including rescue breathing, to dispel these myths and misconceptions. Staying informed with accurate information is crucial for providing effective and timely emergency medical care.
