title: [The use of noninvasive positive pressure ventilation in the early postoperative period after cardiovascular surgery].
abstract: We used noninvasive positive pressure ventilation (NPPV) in 7 ICU patients after cardiovascular surgery. In 6 patients, we measured the variables of hemodynamics and arterial oxygenation by application of this nasal respiratory support (Companion 320 I/E, Puritan Bennett). Ventilator settings of expiratory positive airway pressure (EPAP) 3 cmH2O and inspiratory positive airway pressure (IPAP) 10 cmH2O were used and continued for 30 minutes. There were no significant changes in any hemodynamic variables during NPPV. Arterial oxygenation also remained unchanged at 30 min after discontinuation of NPPV. To conclude the efficacy of NPPV after cardiovascular surgery, higher level of IPAP and the combination with postural drainage should be studied further.
