Safety First

  • Transfer the patient out of traffic.
  • Transfer the patient from wet places and dry the individual. (Those who are drowning should be dried immediately; standing water like puddles, gutters, or pools should also be avoided.)
  • Keep your own safety in mind.

Assess the Patient

  • Shake them, and speak loudly.

  • Check if there is breathing. (Occasional gasping, known as agonal breathing, should not be counted as breathing.)

Call EMS

  • Send another person for help and to retrieve an AED.

  • When alone, call out for help while checking the patient’s pulse and breathing. (The AHA stresses the importance of cellphones with built-in speakerphones, allowing you to call for assistance without abandoning the patient.)

CPR

  • Check pulse.
  • Deliver chest compressions and breaths immediately.

Defibrillate

  • Attach the AED as it becomes available.
  • Pay attention to and administer the steps as they are directed.

CPR Steps

  1. The carotid pulse should be checked on the side of the neck. Don’t waste time feeling for a pulse longer than 10 seconds. Even if you do not feel the pulse, start a cycle of CPR with two breaths and 30 chest compressions.
    (Figure 4a).
  2. The heel of one hand should rest on the lower half of the sternum (Figure 4b).
  3. The other hand should be above the first (Figure 4c).
  4. Straighten your arms and press down. Each compression should reach 2 inches into the patient’s chest, with a rate of 100 to 120 compressions per minute.
  5. Between each compression, stop pressing and allow the chest wall to recoil naturally. Do not lean or rest on the chest between compressions, as this prevents the heart from refilling between compressions, making CPR less effective.
  6. Tilt the head and lift the chin to open the airways after 30 compressions (Figure 4e &4f).
    • a. Tilt the head back after putting your hand on the patient’s forehead.

    • b. Lift the jaw with your index and middle fingers on the lower jaw.

    • c. If the patient has a neck injury, do not tilt the head; simply use the jaw-thrust.

    • d. In applying the jaw-thrust maneuver, hold the lower jaw’s angles and lift with both hands, moving the jaw forward from either side. Open the lower lip with your thumb if the patient’s lips are sealed.

  7. Watch the chest rise and give a breath. Do this again while administering a second breath.
  8. Chest compressions should then be resumed. Switch between compressions and rescue breaths while minimizing interruptions in the compressions.
