Figure 2From: Decay in chest compression quality due to fatigue is rare during prolonged advanced life support in a manikin modelDevelopment of chest compression depth. Development of chest compression depth for each of 19 resuscitation attempts, the good are illustrated in A (5/19, 26%), the bad in B (9/19, 47%) and those with decay in C (5/19, 26%). Arrows indicate when each paramedic first developed decay in chest compression depth to < 40 mm. See text for definition of groups.Back to article page
