Background: The total prevalence of respiratory failure is unknown since it is a syndrome instead of a single disease happening. It's possible, but not certain, that race has an influence in the emergence of acute respiratory failure (ARF). Aim: The purpose of the research was to contrast the efficiency of Noninvasive ventilation (NIV) with oxygen mask (OM) in individuals with ARF shortly following scheduled extubation.  Methods: The research was done between December 2012 and October 2014 at three different respiratory ICUs at the hospitals of Kasr Al-Ainy, El-Mehalla Chest, and El-Abbassia Chest. 56 cases with type II respiratory failure, who needed ventilator and intubation assistance for longer than two days, were included in the research; while 4 patients who had successfully extubated themselves were not. NIV group (26 patients): Cases were ventilated utilizing either a NIV ventilator or an ICU ventilator set to a pressure support ventilation mode with a PEEPext added. PEEPext was started at 5 cm H2O and raised until oxygen saturation was maintained at >92% while Pinsp was titrated to patient tolerance. Attaining these parameters (oxygen saturation 92 percent, respiratory rate 25 breaths/min, and pH > 7.35) was the goal. We increased the FiO2 until we had a SaO2 of 92%. Each patient wore a full-face mask while receiving treatment. Results: NIV group had significantly lesser heart rate (HR) 1 hour after trial. HR non-significantly increased from MV to SBT in both groups. HR increased from SBT to 1 hour after trial in both groups, but the changes were significant only in SMT group. Conclusion: Patients with chronic respiratory illness may benefit from utilization of non-invasive ventilation immediately following planned extubation as it decreases the rates of reintubation, VAP, and mortality in the ICU.
