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

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

  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)* -
  1. 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.
