comparing high flow nasal cannula , conventional oxygen tharapy and non invasive ventilation post-extubation period for patients mechanically ventilated due to respiratory failure regarding re-intubation rate, ICU outcome & 28 days mortality

patients with respiratory failure either type I or type II planned for extubation will be divided into 3 groups post extubation :

Group I: will receive high flow nasal cannula giving oxygen 60 litres / minute flow group II: will receive nasal cannula up to 10 litres / minute group III: will receive non invasive ventilation

Data of the patients will be collected for 28 days post-extubation and analysed

Inclusion Criteria:

• respiratory failure type I and Type II

Exclusion Criteria:
