Table 1 Data on Quality of Cardiopulmonary Resuscitation (CPR)

Variable	Finding
Episode duration, (h:min:s)	3:40:50
Total number of compressions (n)	25159
Chest compression depth (mm)	43 (6)
Fraction of 1 min epochs with compression depth < 40 mm, No (%)	63/222 (28)
Chest compression force (kg)^a	27 (7)
Chest compression rate (min^-1)^b	115 (6)
Fraction of 1 min epochs with compression rate <90 or >120 min⁻¹, No (%)	4/222 (2)
Compressions delivered, (min^-1)^c	113 (7)
Incomplete chest release of total number of compressions, No (%)^c	288/25159 (1)
Incomplete chest release per 1 min epochs, %^d	0 (0, 0)
Incomplete chest release force, (kg)^e	0.7 (0.3, 1.3)
Compression as part of duty cycle, %	42 (5)
No flow fraction^f	0.02 (0.05)
No flow time per 1 min epochs, s^f	1 (3)

The data are presented as number and percentage, as median and 25 % to 75 % interquartile range (IQR), or as mean and standard deviation (SD) as appropriate (non-normal or normal distribution, respectively).
^aIndicates the force to needed to the chest compression.
^bIndicates the rate of compressions when delivered.
^cIndicates the average number of compressions actually given per minute during the resuscitation attempt.
^dIndicates the incomplete chest wall decompression after chest compression phase.
^eIndicates the residual lean weight (leaning force) after chest compression phase.
^fIndicates the proportion of time without chest compressions during the resuscitation attempt.
