About this trial
Acute chest syndrome (ACS) is the leading cause of admission to intensive care and the leading cause of death in patients with sickle cell disease. Irrespective of the cause of ACS, there is an heterogeneity in pulmonary ventilation/perfusion ratios, leading to worsening of the disease.
Efficiency of awake prone positioning (APP) in acute respiratory failure (ARF) was particularly highlighted during the COVID-19 pandemic. Several physiological factors contribute to this benefit including an improvement in ventilatory drive and gas exchange.
The investigator hypothesize that APP could lead to clinical improvement in ACS in terms of oxygenation and ventilatory drive, by improving the heterogeneity of ventilation
