Along with early defibrillation, high quality CPR with minimal interruptions is one of the two factors that has been shown to improve cardiac arrest outcomes. How do we know if high quality, effective CPR is being performed?Objective measures of high-quality CPR include: Compression rate;Compression depth & recoil;ETCO2; and Chest Compression Fraction (CCF).The role of the CPR coach on the code team.The advantages and use of real-time feedback devices to monitor the rate, depth, and chest recoil of CPR compressions. The use of end tidal waveform capnography.A no-tech way to monitor effective CPR if no compression feedback device or ETCO2 capnography isn’t available.Connect with me:Website:  https://passacls.com@PassACLS on X (formally known as Twitter)@Pass-ACLS-Podcast on LinkedInGive back - buy Paul a bubble tea hereGood luck with your ACLS class!
