Time periods related to the 96 episodes of cardiac arrest and cardiopulmonary resuscitation

CPR variables	Mean ± SD (median) value	Variation
Δt between CA and resuscitation (minutes; N = 66)	0.68 ± 1.3	0 - 9
Δt between CA and defibrillation (minutes; N = 6)	7.1 ± 5.1 (7.0)	1 - 15
Δt between CA and medication (minutes; N = 45)	2.5 ± 2.4 (2.0)	0 - 10
Δt between CA and OTI (minutes; N = 8)	4.8 ± 2.5 (5.0)	2 - 10
Duration of CPR (minutes; N = 96)	16.3 ± 16.7 (11.0)	2 - 107

CPR - cardiopulmonary resuscitation; SD - standard deviation; Δt - time period; CA - cardiac arrest; OTI - orotracheal intubation.
