What are "periodic breathing" and "ahi" in regards to obstructive sleep apnea?

OSA: If your breathing is not controlled to your satisfaction please go back too your sleep doctor. Doctors, me included, aren't always right the first time.

OSA: Periodic breathing (periodic stopping breathing) and AHI are the same thing. Your AHI is the number of times you stop breathing for 10 seconds or more during one hour. If you have a number over 5 you have OSA. As the number gets higher, you severity and risk increase.

Sleep Study terms: Periodic breathing: is a respiratory pattern of young infants during the first few weeks of life and is due to “immaturity.” The Apnea Hypopnea Index (AHI) is an air flow decrease 70% for at least 10 seconds with persistent respiratory effort.

AHI: AHI is apnea-hypopnea index. Number of apneas or hypopneas per hour. Used to determine severity of OSA. Periodic breathing is a normal variation of breathing found in premature and full term infants
