Assessment of outcome of using high flow oxygen and t piece ventilation among patients receiving mechanical ventilation during wean off phase

Abstract

Delay extubation is highly associated with mortality and morbidity. Timely discontinuation from mechanical ventilation is very crucial in critically ill patients. High flow oxygen therapy gives more physiological advantages and improves conditions like hypoxemic respiratory failure, post-operative respiratory failure, palliative care, hypercapnic respiratory failure, acute exacerbation of COPD, and pre-intubation oxygenation. With this study, we might reduce the days on mechanical ventilation and bring back to normal respiration hence saving the high cost of ventilators. High-flow oxygen system is more comfortable and easily tolerable and improves the efficacy of ventilation by reducing dead space carbon dioxide accumulation hence can be used in the wean-off phase to overcome respiratory failure whereas use of t-piece during spontaneous breathing is commonly used during weaning from mechanical ventilation. Among both method outcome is specific but the rate of reintubation after HFNC is significantly less and tolerance is more. Main objective of this study is to overcome weaning failure by comparing HFO and T –piece during weaning phase
