High flow nasal oxygen therapy can be used to improve oxygenation after extubation. In this study, we aimed to compare high flow nasal oxygen therapy with simple oxygen face mask treatment in the weaning process of geriatric intensive care unit patients.

Materials and Method: Fifty-three patients above the age of 65 were retrospectively included in the study. High flow nasal oxygen therapy was initiated to patients with partial pressure of oxygen/fraction of inhaled oxygen<150 within 48 hours of extubation. Patients with partial pressure of oxygen/fraction of inhaled oxygen ?150 were treated with oxygen masks with 10-15L/min flow. The two groups were compared for reintubation and mortality. A cut-off partial pressure of oxygen/ fraction of inspired oxygen value for reintubation requirement was calculated.

Results: Reintubation rates were 51.6% in Group-HFNOT and 54.5% in Group- Mask. Mortality rates of reentubated patients; Group-HFNOT 38.7%, Group-Mask 40.9%. There was no significant difference between the groups. The mean baseline partial pressure of oxygen/fraction of inspired oxygen value was 119.7±18.4 for Group-HFNOT, and a cut-off value of 107 for predicting reintubation was calculated.

Conclusion: High flow nasal oxygen treatment can be preferred for geriatric patients with respiratory failure during the weaning process with appropriate patient selection. Keywords : Geriatrics; Oxygen inhalation therapy; Ventilator weaning; Respiratory insufficiency; Critical care
