what is the indication for mouth to mouth rescue breaths

Mouth-to-mouth resuscitation, also known as rescue breathing, is a crucial life-saving technique used when someone stops breathing or has severely compromised breathing. Knowing when to perform this technique is critical, as improper use can be harmful. This article outlines the key indications for initiating mouth-to-mouth rescue breaths. It's important to remember that this information is for educational purposes and should not replace professional medical training. Always prioritize calling emergency medical services (EMS) immediately.

When to Start Mouth-to-Mouth Rescue Breaths

The primary indication for starting mouth-to-mouth rescue breaths is the absence of normal breathing or inadequate breathing. This means the person is not breathing at all, or their breaths are too shallow, infrequent, or ineffective to provide adequate oxygen to the body. Let's break this down:

1. Absence of Breathing

This is the most straightforward indication. If you check for breathing and find absolutely no chest rise or fall, no air movement felt at the nose or mouth, and no sounds of breathing, then mouth-to-mouth resuscitation is strongly indicated. You should begin CPR immediately.

2. Inadequate Breathing (Agonal Gasps)

Sometimes, a person may exhibit what are known as agonal gasps. These are infrequent, shallow, and irregular breaths. While they look like breathing, they are often ineffective in delivering oxygen to the body. These gasps are a sign of cardiac arrest and should be treated as if the person isn't breathing at all; begin CPR immediately including mouth-to-mouth rescue breaths.

Identifying the Need for Rescue Breaths: A Step-by-Step Approach

Check for responsiveness: Gently tap the person and shout, "Are you okay?"
Check for breathing: Look for chest rise and fall, feel for breath on your cheek near their mouth and nose, and listen for breathing sounds for no more than 10 seconds.
If unresponsive and not breathing or only gasping: Call emergency medical services (911 or your local equivalent) immediately. Start CPR, including rescue breaths.

Important Considerations

Unconsciousness: Rescue breathing is almost always performed on an unconscious person. A conscious person who isn't breathing normally likely has a serious underlying medical condition and needs immediate medical attention; call EMS immediately.
Cardiac Arrest: Often, the need for rescue breaths goes hand-in-hand with cardiac arrest. CPR, which includes chest compressions and rescue breaths, is essential in these situations.
Obstructions: If a foreign body airway obstruction is suspected, you need to perform the Heimlich maneuver first to clear the airway before attempting rescue breaths.

When Mouth-to-Mouth May Not Be Appropriate

In certain situations, mouth-to-mouth rescue breaths might not be the most appropriate or feasible action:

Significant risk of infection: If you are concerned about exposure to infectious diseases (e.g., bloodborne pathogens), barrier devices should be used, or chest compressions alone should be prioritized until professional help arrives.
Personal safety concerns: If the situation is unsafe for you (e.g., violence, hazardous materials), prioritize your own safety and call emergency services. Your intervention won't help if you become a victim.
Presence of a trained rescuer: If another trained rescuer arrives, follow their lead and instructions.

Conclusion

Mouth-to-mouth rescue breaths are a life-saving intervention, but only when indicated. The primary indicators are the absence of normal breathing or the presence of only ineffective agonal gasps. However, always prioritize calling emergency medical services immediately and only perform CPR if you are trained and comfortable doing so. Knowing when and how to perform rescue breaths can be the difference between life and death, but proper training is essential. Seek out a CPR certification course to learn the proper techniques and safety measures. Remember, this article is for informational purposes only and shouldn't replace professional medical training.
