Effect of High Flow Nasal Cannula Versus Continues Positive Airway Pressure in Adults With Obstructive Sleep Apnea

Effect of High Flow Nasal Cannula (HFNC) Versus Continues Positive Airway Pressure (CPAP) in Adults With Obstructive Sleep Apnea

The participants whom undergo Polysomnography study (Sleep study) and are found to have mild, moderate or severe Obstructive Sleep Apnea (OSA) will have two consecutive titration nights. Randomly, they'll do (CPAP) titration followed by (HFNC) titration or vice versa. To explore the possibility of the CPAP not being superior to HFNC in reduction of sleep apnea events.

The participants undergo three nights in the Sleep Lab. In their first night they perpetrate Polysomnography study (Sleep study) and then classifies to have mild, moderate or severe Obstructive Sleep Apnea (OSA) or not. Those who are diagnosed with OSA, will undergo two consecutive titration nights. Randomly, they'll do (CPAP) titration followed by (HFNC) titration or vice versa. To explore the possibility of the CPAP not being superior to HFNC in reduction of sleep apnea events.
