Gasping in Response to Basic Resuscitation Efforts: Observation in a Swine Model of Cardiac Arrest

Table 1

(a) Frequency of gasping in relation to the resuscitation protocol applied. (b) Frequency of gasping in relation to the 24-hour neurological outcome.

				Frequency
Untreated VF time	Groups	N	Mean (SD)	Median (P25–75)	Kruskal-Wallis test
(a) By Treatment					H (3) = 30.7,
5 and 6 minutes	30 : 2	16	1.1 (2.1)	0.07 (0–1.3)	𝑃<.001
	CCC	15	8.4 (6.7)	6.4 (0.8–15.6)

	CCC	16	21.1 (10.9)	21.2 (12.8–31.2)
b) By Outcome					H (3) = 38.8,
5 and 6 minutes	Disabled/dead	19	1.1 (2.2)	0.14 (0–0.8)	𝑃<.001

Posthoc analysis
N ∶number of animals per group; SD: standard deviation; P25–75: 25th–75th percentile.
Frequency = number of spontaneous ventilations or gasps per minute. Mann-Whitney tests with exact significance levels and Bonferroni correction, 𝑃=.008).
