Table 1 Physiological variables during the two modes of mechanical ventilation, pressure-regulated pressure control (PRVC) and volumne control (VC)

From: A comparison of volume control and pressure-regulated volume control ventilation in acute respiratory failure

  PRVC (n = 44) VC (n = 44) P
PIP (cmH2O) 20 (19-23) 24 (23-27) < 0.0001
MAIP (cmH2O) 10 (9-11) 10 (9-11) ns
PaO2 (mmHg) 98 (93-111) 96 (92-108) ns
PaCO2 (mmHg) 43 (40-46) 43 (40-46) ns
pH 7.38 (7.11-7.65) 7.38 (7.10-7.65) ns
MAP (mmHg) 76 (73-83) 77 (74-84) ns
  1. Values are means (95% confidence limits). PIP = peak inspiratory pressure; MAIP = mean airway pressure; PaO2 = partial pressure of arterial oxygen; PaCO2 = partial pressure of arterial carbon oxide; MAP = mean arterial blood pressure.
