Contributor: Aaron Lessen, MD Educational Pearls: Pulse checks are necessary during CPR to check for return of spontaneous circulation (ROSC) Previous studies have shown that assessing ROSC with palpating for pulse are not a very consistent Study compared palpating pulses at carotid/femoral artery versus a newly contrived gold standard for pulse checks The gold standard used was an increase in end tidal CO2 + cardiac activity on ultrasound + perfusing rhythm on ECG Carotid artery palpation was the best location to confirm pulse during pulse check, although femoral artery palpation Carotid artery palpation was 92% accurate versus 82% accuracy with femoral pulse check Regardless of chosen site, remember 10 seconds is the maximum amount of time for a pulse check before resuming CPR References Yılmaz G, Bol O.
