BLS for Healthcare Professionals
Basic life support (BLS) certification helps medical professionals understand how to treat patients facing life-threatening emergencies. During a BLS training course, you’ll learn how to perform CPR, proper AED use, how to treat choking victims, and related topics. The certification is typically recommended for healthcare providers and it is a job requirement for many doctors, nurses, dentists, EMTs, and more.

Remember C-A-B

  • C: Chest Compressions – deliver chest compressions with hard and fast pressure to the victim’s chest.
  • A: Airway – open the airway by tilting the victim’s head back and lifting their chin.
  • B: Breaths – administer mouth-to-mouth breathing.

Confirm scene safety

Adult/Child/Infant

Only approach the victim if it is safe to do so. If the scene is not safe, move to a safer location and contact emergency responders.

Assess the victim’s responsiveness

Adult/Child/Infant

If the victim is unresponsive, activate the emergency response system and call 911 for help. If there is another bystander, have them find an AED.

Check the patient’s breathing and pulse

Check to see if the patient is breathing and check for a definite pulse within 10 seconds.

Adult/Child

Look for a pulse at the carotid artery located on the patient’s neck.

Infant

Look for a pulse at the brachial artery located on the patient’s upper arm.

Administer rescue breathing

Rescue breathing should be administered if the patient has a definite pulse but is not breathing.

Adult

Follow a cycle of 1 breath every 6 seconds or 10 breaths per minute and check their pulse every 2 minutes.

Child/Infant

Follow a cycle of 1 breath every 2-3 seconds and assess pulse for no more than 10 seconds. If their pulse is under 60/minutes with poor perfusion despite rescue breathing, add compressions.

Administer CPR

CPR should be administered if the victim has no detectable pulse.

Adult

Give 30 compressions per 2 breaths.
Use the AED when available.

Child/Infant

If there is 1 rescuer present, give 30 compressions per 2 breaths.
If there are 2+ rescuers present, give 15 compressions per 2 breaths.
Use the AED when available.

AED use

Once the AED arrives, it should be used immediately.

Adult/Child/Infant

Use the AED as soon as available. Follow the instructions on the AED. If the rhythm is shockable, give 1 shock then resume CPR. If the rhythm is not shockable, resume CPR for 2 minutes.

Compression rate

Adult/Child/Infant

Compressions should be administered at 100-120 compressions per minute.

Compression depth

Adult

Compressions should be at least 2 inches deep.

Child

Compressions should be at least ⅓ the depth of the chest, usually about 2 inches.

Infant

Compressions should be ⅓ the depth of the chest, usually about 1.5 inches.

High-Quality CPR

It is imperative that high-quality CPR is administered to give the patient the best possible chance of survival. Remember these rules for high-quality CPR:

  1. Once you recognize cardiac arrest, be sure to start chest compressions within 10 seconds.
  2. Allow the chest to completely recoil after each compression.
  3. Minimize interruptions between compressions. Try to keep any interruptions under 10 seconds.
  4. Deliver fast, hard chest compressions at the appropriate rate and depth.
  5. Ensure that the chest is rising with rescue breaths for effective breath support.
  6. Prevent excessive ventilation.

Key Terms:

  • BLS:
    Basic Life Support
  • AHA:
    American Heart Association
  • CPR:
    Cardiopulmonary resuscitation
  • AED:
    Automatic external defibrillator
  • Compression rate:
    The compression rate is the speed at which chest compressions are administered when performing high-quality CPR.
  • Compression depth:
    The compression depth refers to the desired amount that rescuers should press down on the patient’s chest during chest compressions. To give successful CPR, the rescuer needs to press down far enough into the patient’s chest in order to mimic the heart pumping blood and restore blood flow.
  • Rescue breathing:
    Rescue breathing is when the rescuer blows air into the patient’s mouth to create artificial breath during mouth-to-mouth CPR. It can be performed on its own or in conjunction with chest compressions.
