Sleep apnea basically happens when you stop breathing for short time spans, in your sleep and then wake up all of a sudden to catch your breath - such a complete loss of breathing for 10 seconds or longer counts as an apnea. Check out here to know more about apnea - https://wellawaresystems.com/best-cpap-machine/. The apneas are analysed based on the AHI – Apnea-Hypopnea Index, on which the number of apneas is counted. Lesser than five apneas per sleeping hour are considered to be normal. When this number gradually increases, the severity of the apnea gradually increases.
