Echocardiography in Life Support (ELS)
Echocardiography in Life Support (ELS) requires careful timing with the rhythm check. During this 10-second window the probe is often set to maximum depth and increased gain, to increase the likelihood of locating the heart rapidly. If the heart cannot be seen during the rhythm check, the probe should be removed at 10 seconds and CPR recommenced.
