Analysis of ventilation and hemodynamic changes resulting from noninvasive bilevel pressure mechanical ventilation applied to patients with congestive heart failure

Ariadne Fernandes de Barros et al. Luciana Costa de Barros Márcia Cristina Sangean Joaquim Minuzo Vega

OBJECTIVE: To observe in practice how noninvasive bilevel positive pressure, applied at different levels, may interfere with systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), and peripheral oxygen saturation (SpO2), in patients with congestive heart failure (CHF). METHODS: Fourteen CHF patients (mean age 62.85 years) were treated with noninvasive bilevel mechanical ventilation. Patients were consecutively treated with an expiratory positive airway pressure (EPAP) of 5 cmH2O, 10 cmH2O, 15 cmH2O, 10 cmH2O, and 5 cmH2O, maintaining a variation in pressure (deltaP) of 5 cmH2O between the inspiratory pressure (IPAP) and the expiratory pressure (EPAP). Ventilation and hemodynamic data were collected at these time points, as well as 5 minutes before the beginning of the protocol and 5 minutes after its completion. RESULTS: A statistically significant difference was observed in the respiratory rate between the moment just before the beginning of the protocol and 5 minutes after positive pressure mask placement (p=0.022), and in oxygen saturation, between the final minute of EPAP at 5 cmH2O and after the removal of the mask (p=0.05). CONCLUSION: Noninvasive bilevel mechanical ventilation improves oxygenation and reduces respiratory work, thus being beneficial for patients with congestive heart failure. It was not possible to observe statistically significant changes in the hemodynamic data due to the small number of patients and to other associated heart diseases.
