Comparisons of arterial blood gas parameters in two experimental groups 1 min after the start of cardiopulmonary resuscitation in a rat model of respiratory arrest.


	IPPV group	CFIO group	value

pH	7.01 (6.98–7.05)	6.99 (6.97–7.00)	0.06
PCO₂	89.95 (86.70–91.63)	99.90 (97.98–103.00)	<0.001
O₂	56.10 (54.68–58.25)	83.10 (81.05–87.50)	<0.001
HCO₃-	23.90 (22.58–24.95)	24.10 (23.10–24.98)	0.59
Base excess	−4.70 (−6.35–−4.15)	−4.40 (−5.13–−4.08)	0.40
Lactate	4.55 (4.10–5.10)	4.85 (4.30–5.15)	0.45

Mann–Whitney test, median (IQR), was considered statistically significant. Statistical significant. ABGA, arterial blood gas analysis; CPR, cardiopulmonary resuscitation; IPPV, intermittent positive pressure ventilation; CFIO, continuous flow insufflation of oxygen.
