does obesity cause hypoxemia
Obesity hypoventilation (HI-po-ven-tih-LA-shun) syndrome (OHS) is a breathing disorder that affects some obese people. In OHS, poor breathing results in too much carbon dioxide (hypoventilation) and too little oxygen in the blood (hypoxemia). OHS sometimes is called Pickwickian syndrome. To understand OHS, it helps to understand how the lungs work.
In addition, evidence on their combined effect on all-cause mortality is conflicting (17, 18). To address the interaction of obesity and OSA, we used a large historical cohort of patients with suspected OSA and investigated whether obesity influences the effect of nocturnal hypoxemia on cardiovascular events.
