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
