2. Fig. 1
Example chest deflection curves defining (a) chest compression depths, (b) chest release forces, (c) chest compression rates and (d) compression duty cycles. Each chest compression cycle is represented by a dashed line, with the circular markers defining the point/range reported for each internationally recommended target. The shaded region represents the area under the chest deflection curve and the dashed-dotted box represents the product of the chest compression depth and the chest compression cycle time.

5. Fig. 4
Simulated chest compression quality measures, illustrated against evidence based quality targets, for both two-thumb (TT) and two-finger (TF) chest compressions, as performed by the feedback and control groups at the experimental stage. Chest compression quality targets are illustrated by dashed lines. Compression depth targets were 36.7–46mm, release force targets were <2.5kg and <0.5kg, compression rate targets were 100–120min−1 and duty cycle targets were 30–50%.

The feedback system: Chest deflection is detailed such that the resuscitator remains within the target range (i.e. green zone), whilst not compressing too deeply and thus risking intra-thoracic injury (red zone). A minimum depth is required during the release phase (blue zone). The desired compression rate is also described by both the green flashing light, and a ‘metronomic’ beep.
