Lorem ipsum, or lipsum as it is sometimes known, is dummy text used in laying out print, graphic or web designs. The passage is attributed to an unknown typesetter in the 15th century who is thought to have scrambled:

ANSWER: Between 2.0 and 2.4 inches (5-6 cm) The 2015 Guidelines added a new upper limit for compression depth.Lorem ipsum, or lipsum as it is sometimes known, is dummy text used in laying out print, graphic or web designs.

2During CPR, which measurable metric should be at least 60%:

ANSWER: Chest compression fraction The chest compression fraction quantifies the amount of time that compressions are actually delivered. The CCF should be at least 60%, and limiting interruptions can significantly improve it.

3True or False: It is imperative to pause chest compressions for at least 20 seconds to check the underlying rhythm.

ANSWER: False Minimizing interruptions is critical during CPR. Rhythm checks should be brief, with CPR resuming immediately after a shock is delivered, if a shock is indicated.

4True or False: For an average adult, the 2020 Guidelines-recommended compression rate has remained unchanged since the 2005 Guidelines.

ANSWER: False In 2005, the recommended rate was approximately 100 compressions per minute, which changed in 2010 to at least 100. The recommended rate was further refined to 100-120 compressions per minute in the 2015 Guidelines and has remained the same in the latest 2020 Guidelines.

5Residual leaning is primarily a hindrance to:

ANSWER: Full chest recoil Full chest recoil is crucial during CPR. It allows the heart to refill with venous blood before the next compression so that output can be maximized with each compression.

6True or False: Technology exists today that allows you to see an underlying rhythm while performing CPR.

ANSWER: True The R Series® monitor/defibrillator includes See-Thru CPR® to help minimize pause time during CPR and increase chest compression fraction by filtering out CPR artifact.

7During ventilation, the Guidelines suggest that you aim for ___ breaths per minute to provide sufficient oxygen to the blood without impeding perfusion.

ANSWER: 10 Aim for a rate of 10 breaths per minute to minimize the impact of positive-pressure ventilation on blood flow.

8What do you think is more important during CPR?

ANSWER: Both are critically important A lot of emphasis has been placed on the importance of good chest compressions, much less on “good” chest recoil, however it is one of the components of high-quality CPR. The Guidelines recommend allowing for full chest recoil after each compression to allow the heart to fill again with venous blood.
