BLS and ACLS Survey


BLS and ACLS Surveys


Foundational to every ACLS Algorithm is the BLS survey. The BLS Survey is the first step that you will take when treating any emergency situation, and there are 4 main assessment steps to remember. These four steps are designated by the numbers 1, 2, 3, and 4.

This is an outline of the 4 steps in the BLS Survey :
(1) Check responsiveness by tapping and shouting, “Are you all right?” Scan the patient for absent or abnormal breathing (scan 5-10 seconds).
(2) Activate the emergency response system and obtain a AED. If there is more than one rescuer, have the second person activate emergency response and get the AED/Defibrillator.
(3) Circulation: Check for a carotid pulse. This pulse check should not take more than 5-10 seconds. If no pulse is palpable begin CPR.
(4) Defibrillation: If there is no pulse, check for a shockable rhythm with the AED or defibrillator as soon as it arrives. Follow the instructions provided by the AED or begin ACLS Protocol.
For a more in-depth review of BLS refer to the American Heart Association’s BLS Provider Manual.

Remember to assess first then perform appropriate actions, and after each action…reassess.

The ACLS Survey uses the ABCD model to systematize the ACLS process. The ABCD’s of the ACLS Survey are:
(A) Airway: Maintain airway and use advanced airway if needed. Ensure confirmation of placement of an advanced airway and secure the advanced airway device.
(B) Breathing: Give bag-mask ventilation, provide supplemental oxygen, and avoid excessive ventilation. Also, adequacy of ventilation and oxygenation should be monitored during this step.
(C) Circulation: Obtain IV access, attach ECG leads, identify and monitor arrhythmias, giving fluids if needed, and use defibrillation if appropriate.
(D) Differential diagnosis: Look for reversible causes and contributing factors for the emergency.

The ACLS survey is included in every ACLS algorithm and like the BLS Primary Survey, it helps to systematize the resuscitation process and improve patient outcomes.

The objective of the review of these ACLS Algorithms is to help prepare you for the ACLS written test and the ACLS Megacode. After reviewing, you can test your skills and knowledge by accessing the ACLS Megacode Simulator and ACLS practice exams.

  1. Found your site 2 years ago…… Would never take my certification without this site. Will certify next week, not anxious at all.
    Thank you!

  2. You Know, It’s always agood idea to start out with the basics. What is a cycle? Do 5 cycles add up to 2 minutes? If not, which is most important?

  3. Just joined. So far I am impressed with the format. Very easy to review and follow.

  4. Great site. Passed ACLS site very helpful
