A recent study shows that people who suffer from Obstructive Sleep apnea (OSA), may also experience a condition named as ‘Hypercapnia’(refers to high levels of Carbon Dioxide in the blood). According to a study in Japan of 1,227 people with OSA, 14 % had Hypercapnia, and the condition was more likely to be in obese individuals & those who had severe OSA. They found that after 3 months of use of CPAP (Continuous Positive Airway Pressure), more than half of these patients had corrected their Hypercapnia. These results support the idea that CPAP effectively reduces the symptoms of OSA & related adverse health effects.
