Introduction: Noninvasive positive pressure ventilation (NIPPV) has become an integral tool in the management of acute hypercapnic respiratory failure (AHRF) in chronic obstructive pulmonary disease (COPD). This study was performed to evaluate the early effects of NIPPV on pulmonary artery pressure (PAP), serum N-terminal pro BNP (NT-proBNP), and ventilatory parameters in the COPD patients with AHRF. Materials & Methods: This quasi-experimental study was conducted on 20 COPD patients with AHRF. The participants received the standard treatment in addition to NIPPV. There was no contraindication for NIPPV. Arterial blood gas analysis, Doppler echocardiography (for measuring PAP), and plasma NT-proBNP measurements were performed before and after NIPPV. Results: According to the results, the mean age of the participants was 54.57±15.43 years. Furthermore, the mean pressures of carbon dioxide (PCO2), NT-proBNP levels, and PAP were 72.33±13.96 mmHg, 4333.90±6542.20 pg/ml, and 47.5±6.38 mmHg, respectively. After one week of NIPPV, there were statistically significant differences among the mean pH, PaCO2, PAP, and NT-proBNP (P
