This guide offers comprehensive insights into infection prevention during BLS, including essential techniques, best practices, and guidelines to maintain a safe and effective response. Equip yourself with the knowledge to provide life-saving care while minimizing infection risks.


Understanding Infection Control in Basic Life Support

Infection control in BLS involves a set of practices aimed at preventing the transmission of infectious agents during life-saving procedures. The primary goal is to protect the patient and the rescuer from potential infections that occur through contact with bodily fluids or airborne pathogens.

Common infections that are transmitted during BLS include viral infections (such as HIV, Hepatitis B, and C), bacterial infections (such as tuberculosis), and respiratory infections (such as influenza). These pathogens are transmitted through direct contact with bodily fluids, respiratory droplets, or contaminated surfaces.


What are Standard Precautions in Infection Control?

Standard precautions are fundamental to infection prevention and control in any healthcare setting, including during Basic Life Support. These precautions are designed to minimize the risk of transmission of infectious agents from both recognized and unrecognized sources.


Hand Hygiene

Hand hygiene is the most effective way to prevent the spread of infection. Proper hand hygiene techniques and practices are essential for BLS providers to ensure their safety and that of the patients they assist. Here are the proper techniques for hand hygiene:


Washing with Soap and Water

  1. Wet hands with clean, running water (warm or cold).
  2. Apply soap and lather well, covering all surfaces of the hands, including the backs of hands, between fingers, and under nails.
  3. Scrub for at least 20 seconds. A good rule of thumb is to hum the "Happy Birthday" song twice.
  4. Rinse thoroughly under running water.
  5. Dry hands using a clean towel or air dry them.


Using Alcohol-Based Hand Sanitizer

  1. Apply the product to the palm of one hand (enough to cover all surfaces).
  2. Rub hands together, covering all surfaces, until hands feel dry. This should take around 20 seconds.


Importance of Hand Hygiene

  • Before and After Patient Contact: Prevents the transfer of infectious agents from the responder to the patient and vice versa.
  • After Removing Gloves or PPE: Gloves and PPE become contaminated; proper hand hygiene removes any potential contaminants.
  • After Contact with Potentially Contaminated Surfaces: Surfaces touched during BLS harbor infectious agents, making hand hygiene crucial to prevent further spread.


Personal Protective Equipment (PPE)

PPE is vital to creating a barrier between the responder and infectious agents. Proper use of PPE protects both the BLS provider and the patient. Here are the different types and correct usage of PPE:

  • Gloves: Wear gloves before any contact with the patient or bodily fluids. Change gloves between different procedures on the same patient and between patients to avoid cross-contamination. Ensure a proper fit without tears or punctures.
  • Masks: Wear masks to protect against respiratory droplets, especially if the patient is coughing or if aerosol-generating procedures are performed. Ensure the mask covers both nose and mouth snugly.
  • Eye Protection: Use eye protection to shield against splashes or sprays of bodily fluids. Ensure goggles fit securely around the eyes or the face shield covers the entire face.
  • Gowns: Wear gowns in situations with a high risk of extensive contact with bodily fluids. Ensure the gown covers the torso and arms and fits snugly.


Proper Removal and Disposal

  • Remove PPE carefully to avoid self-contamination. Follow a sequence that typically involves removing gloves first, followed by eye protection, gown, and mask.
  • Dispose of used PPE in designated biohazard containers.


Safe Handling of Potentially Contaminated Materials

Handling contaminated materials properly is crucial to prevent the spread of infections. This includes PPE and other items that have come into contact with bodily fluids.

  • Remove PPE using proper techniques to avoid contact with the outside surfaces.
  • Dispose of gloves, masks, gowns, and eye protection in biohazard bags immediately after use.
  • Clean up any spills of bodily fluids using appropriate disinfectants.
  • Use absorbent materials to contain the spill and thoroughly disinfect the area.
  • According to manufacturer guidelines, disinfect reusable equipment (e.g., CPR manikins, medical devices).
  • Use appropriate disinfectants known to be effective against the pathogens of concern.


Handling and Disposal:

  • Segregate potentially contaminated materials from regular waste.
  • Use biohazard bags to dispose of contaminated materials and ensure they are handled and disposed of correctly.
