• During sleep study was around 5, difficult nights have around 2. Most nights have around .5
  • Try taping mouth to lower leaks
  • Try decreasing range of pressure (6-13)
  • Turn off EPR settings if on (exhale pressure relief)
  • When sick - use full mask instead of nasal pillows
• Most common events (worse when sick)
  • CA
  • OA
• Data Targets
  • Ahi lower than 1-2
  • Large leak percent lower than 5%

Settings

• Ramp feature - makes it easier to fall asleep, adjust if lot of OA events in the beginning of the night since it delays effective therapy pressure
• EPR feature - reduces pressure during exhalation but can sometimes worsen OA

Type of events

• Central Apnea (CA): A pause in breathing for at least 10 seconds resulting from a lack of respiratory effort, indicating a failure of the brain to signal the muscles to breathe. Unlike obstructive apneas, central apneas are not caused by airway blockage.
• Obstructive Apnea (OA): A complete cessation of airflow for at least 10 seconds due to a physical blockage in the upper airway, despite continued respiratory effort. This obstruction often leads to snoring and can cause abrupt awakenings.
• Hypopnea (H): A partial reduction in airflow during sleep, lasting at least 10 seconds, accompanied by a decrease in blood oxygen levels or an arousal from sleep. Hypopneas are less severe than apneas but can still disrupt sleep and contribute to daytime fatigue
• Respiratory Effort-Related Arousal (RERA): A sequence of breaths characterized by increasing respiratory effort leading to an arousal from sleep, but not meeting the criteria for apneas or hypopneas. RERAs can fragment sleep and contribute to excessive daytime sleepiness.
