Brief Summary:
This study aims to compare the effectiveness of conventional oxygen therapy oxygen and high-flow nasal cannula therapy on oxygen saturation (SpO2), measuring number of SpO2 drop \>4% of base line oxygen saturation (o2 desaturation index), length of the ICU stay, and the need of use supplemental continuous positive airway pressure (CPAP) support in any of the study groups in the postoperative ICU setting.
Detailed Description:
In the surgical setting, patients with obstructive sleep apnea (OSA) may have increased upper airway collapsibility affecting ventilation and increased sensitivity to sedation from anesthetics and opioids.
Surgical patients with OSA have a high risk for postoperative complications, including cardiac events, hypoxemia, and transfer to the intensive care unit . Continuous positive airway pressure (CPAP) is the gold standard treatment for moderate to severe OSA , and effectively reduces the risk of cardiovascular events. Evidence has shown that CPAP effectively reduces length of ICU stay (LOS) in the postoperative setting. In these scenarios, conventional oxygen therapy and high-flow nasal cannula (HFNC) therapy have been used as an alternative for CPAP non-adherent patients.
HFNC delivers warm, humidified air through a nasal cannula at high flow rates of up to 60 L/min. This high flow rate may increase end-expiratory pharyngeal pressure up to 3 cm H2O, decreasing the force required to alleviate airway collapse . Using a nasal cannula interface in contrast to the CPAP mask may provide a more comfortable experience for patients during sleep .
