AP PSYCHOLOGY

Detailed explanation-1: -Obstructive Sleep Apnea (OSA) is a sleep disorder that involves a significant decrease or cessation of airflow in the presence of breathing effort. An estimated 58% of moderate to severe obstructive sleep apnea is attributable to obesity.

Detailed explanation-2: -Apnea is defined as cessation of breathing for at least 10 seconds; a duration of at least 20 seconds is frequently used to diagnose significant apneas, as normal infants do not have apneas of greater than 20 seconds. Apneas are classified as central, obstructive, or mixed.

Detailed explanation-3: -Obstructive sleep apnea is the most common sleep-related breathing disorder. It causes you to repeatedly stop and start breathing while you sleep.

Detailed explanation-4: -Apnea has one or more of these signs: Not breathing for 20 seconds or longer. Skin color becomes blue or very pale (cyanosis) The heart beats more slowly, less than 80 times in a minute.

Detailed explanation-5: -These breathing “stoppages” can happen a few times per hour or, in more severe cases, 60-100 times per hour or to the point where someone spends more time NOT breathing than they are breathing. When breathing stops, oxygen levels drop significantly and can affect the heart, brain and blood pressure.
