Dr. Kavyashree N, Dr. Ganapathi P

Objective: Use of NIV (BIPAP) versus Facemask in COPD patients admitted to emergency ward with type -2 respiratory failure. This study in regards to arterial blood gas analysis, requirement of intubation and hemodynamic parameters. Materials and methods-study design: Prospective randomised study; This study was conducted after obtaining ethical committee permission. Patients participating in study were explained in their native language about study and written consent was obtained 50 patients in the age groups of less than 80 years with ASA -2 and 3, were divided in to two groups. Group NIV were ventilated with BIPAP with pressure setting adequate to deliver tidal volume of 6-8 ml and Fio2 of 40%.Group FM were ventilated with simple Facemask with 5 liters of o2 per minutes, other pharmacological treatments were continued in both groups similarly. Qualitative test analyzed with chi square test and Quantitative test analyzed with student t test, p value <0.05 is considered statistically significant in all the above test. Results: In NIV patients, pH-3.8+- 0.04, pao2-84.5+-10.37 and in FM pH -7.29+-0.06,pao2-68.8+ -13.34 at 1 hour after. P value is <0.05 Conclusion: NIV is beneficial in COPD patients with type 2 respiratory failure compared to traditional face mask and improve the outcome.
