Efficacy of Feed Forward and Feedback Signaling for Inflations and Chest Compression Pressure During Cardiopulmonary Resuscitation in a Newborn Mannequin

Figure

Figure 1. Design of the visual actuator. A force sensitive resistor is integrated as a pressure sensor in the foil at the intersection of marking of sternum and inter nipple line. The visual indicator consists of an embedded set of six parallel semi-annular electroluminescent strips that light up with increasing pressure.

Tables

**Table 1.** Rhythm Score Values
	First session	Second session	P-value
Legend: Rhythm scores (expressed in percentage, mean ± SD) of nurses and doctors that performed chest compressions and lung inflations during 90 s on a newborn manikin in a ratio of 3:1.
Controls (n = 10)	91 ± 15	90 ± 10	NS
ROLA (n = 10)	85 ± 14	99 ± 2	< 0.05
P-value	NS	< 0.01

**Table 2.** Compression Pressure Values
	First Session	Second Session	P-value
Legend: Compression pressures (expressed in arbitrary units, mean ± SD) measured during 90 s of chest compressions and lung inflations by nurses and doctors on a newborn manikin in a ratio of 3:1. Data are shown for the two sessions. The ROLA group used the ROLA device in the second session. The control group performed two sessions without the ROLA device. NS refers to non significant.
Controls (n = 10)	3.3 ± 1.0	2.4 ± 1.4	NS
ROLA (n = 10)	3.1 ± 1.6	4.9 ± 0.8	< 0.05
P-value	NS	< 0.001
