BLS Adult Algorithm

BLS Adult Algorithm

1. Secure the scene. This means pulling the victim out of standing water, traffic, or other dangerous situation. You should be safe before you begin Basic Life Support.

2.  Check for a response. If the victim is unresponsive and has abnormal respirations (no respirations or gasping/agonal breathing) activate EMS, yell for help, and send someone for an AED. Use a cell phone if one is available.

3. Check for a pulse at the carotid artery (check for no longer than 10 seconds) and check breathing.

If there is a pulse and breathing, continue to monitor and support breathing.

If there is a pulse and no/abnormal breathing, start rescue breathing.

If there is no pulse and no/abnormal breathing:

  • Start high-quality CPR (30 compressions to 2 breaths, 100-120 compressions per minute)
  • Compress chest between 2 and 2.4 inches
  • Allow the chest to fully recoil
  • Continue CPR for 2 minutes or until AED is on the victim, powered up, and ready for use
  • Check heart rhythm using AED
  • Follow instructions on AED, deliver shock as needed
