A recent systematic review compared the timing and diagnostic accuracy of manual pulse check versus point-of-care ultrasound (POCUS) pulse checks (this means placing an ultrasound probe on the carotid or femoral artery to evaluate for a doppler pulse).
The review included seven studies encompassing a total of 469 patients.
Six of the studies assessed the duration of pulse checks, revealing a mean time difference of –1.39 seconds (95% CI: –2.20 to –0.57) in favor of ultrasound.
Three of the studies reported the sensitivity and specificity of POCUS pulse checks, yielding pooled estimates of 99% sensitivity (95% CI: 87%–100%) and 96% specificity (95% CI: 85%–99%). In contrast, two studies evaluated manual pulse checks, with pooled sensitivity of 62% (95% CI: 22%–91%) and specificity of 91% (95% CI: 88%–93%).
As with many systematic reviews, the studies included demonstrated high heterogeneity and generally low methodological quality, indicating that further investigation may still be needed.
