the purpose of this study to evaluate the effect of early awake PP (prone position)application on oxygenation and intubation requirement in patients with acute respiratory failure due to coronavirus disease 2019 pneumonia.
The first group (early prone position-EPP) created for our study was composed of patients who
received PP at least 12 hours early (with the first 48 hours) with the oxygen support of the
reservoir mask, and the second group (non-EPP ) patients who received oxygen with the
reservoir mask but could not be applied early PP due to the patient's incompatibility or
rejection.
Conventional oxygen therapy applied to all patients was given with a reservoir mask, aiming
at oxygen saturation 93% and above, at a flow rate of 6-15 L / min.
Despite all the treatments, the patients who have a follow-up with a respiratory acidosis ,
oxygen saturation value below 93%, applied non invasive mechanical ventilation, in case of
insufficient patient intubated and have invasive mechanical ventilation. In patients who had
regression of glasgow coma scale during follow-up, orotracheal intubation was performed and
invasive mechanical ventilation was performed.
Behavioral: prone position
to lay in prone position at least 12 hour in a day at ICU
Inclusion Criteria:
- Patients who developed acute respiratory failure due to coronavirus disease 2019
pneumonia

edema, carcinogen syndrome, etc.)
- patients who underwent non-invasive mechanical ventilation(NIMV) or intubated from
admission to intensive care,
- those who underwent self prone position under 12 hours were not included in the study.
