Boussignac continuous positive airway pressure for the management of acute cardiogenic pulmonary edema: prospective study with a retrospective control group

Table 2 Physiological responses before and after BCPAP in subgroup of CCU patients.

	Control	BCPAP	p-value
N	35	84
Heart rate baseline	102 (83–125)	104 (86–119)	-
Heart rate after 120 min	102 (82–117)	86 (76–99)*	0.03
Mean arterial pressure baseline	101 (85–118)	103 (79–123)	-
SpO₂ baseline	91 (88–94)	88 (82–92)	< 0.01
SpO₂ after 120 min	94 (92–95)*	95 (92–97)*	-

Data are median (IQR), SpO₂ = peripheral arterial oxygen saturation. The Wilcoxon signed rank test was used to test differences between data collected at baseline and after 120 minutes. * Significant (p < 0.05) within group improvement at 120 minutes compared to baseline.
