Why is it important to check the airway prior performing CPR?

Checking the airway is critically important before initiating cardiopulmonary resuscitation (CPR) for several reasons:

1. Assess Airway Patency: Before starting chest compressions and rescue breaths, it is essential to determine if the person's airway is clear and unobstructed. An obstructed airway prevents effective ventilation and oxygen delivery, compromising the success of CPR.

2. Identify and Remove Obstructions: By examining the mouth and throat, healthcare providers can quickly identify any foreign objects, secretions, or swelling that may be blocking the airway. Promptly removing these obstructions restores airflow and improves the chances of successful resuscitation.

3. Determine Responsiveness: Assessing airway status also helps determine the level of responsiveness of the individual. If the person is responsive and breathing normally, noCPR interventions are necessary, and other appropriate medical assessments should be performed.

4. Initiate Appropriate Rescue Maneuvers: Depending on the condition of the airway, the rescuer can determine the most appropriate rescue maneuvers. If there is an obstruction, performing techniques like the head-tilt chin-lift or jaw-thrust maneuver can clear the blockage and allow proper ventilation. If the person is unresponsive and not breathing, rescue breaths (via mouth-to-mouth or other barrier devices) can be administered effectively when the airway is open.

5. Provide Proper Ventilation: An open and unobstructed airway is crucial for delivering effective rescue breaths, allowing oxygen-rich air to reach the lungs. Without adequate ventilation, CPR efforts may be less effective in restoring spontaneous circulation.
