Excess weight increased the severity of oxygen desaturation in the blood of individuals with sleep-disordered-breathing (SDB) during and after apneas and hypopneas.
Each 10-point increase in BMI predicted a 10 percent increase in the severity of oxygen depletion associated with SDB events.
"This means that if, for example, a six-foot tall, 160-pound 45-year-old man (BMI= 22), had an apnea that produced a six-percent reduction in oxygen saturation, then a man with the same characteristics who weighed 235 pounds (BMI=32) would be expected to have a 6.6 percent reduction in blood oxygen saturation during a similar event,".
