Abstract
The present study included 135 type 1 respiratory failure patients, [28 patients with ACPE, 30 with BA, 25 with CAP, 25 with PE and 27 patients with acute lung injury . Aim: To evaluate the effectiveness of NIPPV in correcting gas exchange abnormalities aiming for avoiding ETI in the management of patients with acute hypoxemic respiratory failure and to identify simple predictors affecting the outcome of theses cases. Result: ” NIV is significantly effective in reducing the need for intubation in patients with acute cardiogenic pulmonary edema, bronchial asthma and CAP. On the other hand, no significant decrease in ETI in ALI and PE patients. ” There were statistically significant decrease in the RR and HR from the first hour to the end of 24 hours of the study in all groups except in PE group where there was no significant change in HR through the 24 hours of the study. ” There were statistically significant increase in PaO2/FIO2 ratio from the 1st hour to the end of 24 hours of the study in all groups. Recommendation: ” Further multicenter studies with a wide database are recommended to confirm our results and to develop a more accurate and specific outcome predictive model for AHRF patients.
