Sleep Testing Center
An HST is an overnight test (completed at home) ordered to diagnose obstructive sleep apnea (OSA). OSA is a condition that causes your airway to be blocked at night. The sleep test involves a small,
battery-operated device (right) that fastens around your chest with a belt. The device records your breathing, oxygen level and snoring.
PAP titration is an overnight sleep test. The goal is to find the right mask and air pressure required to prevent your upper airway from becoming blocked and eliminate breathing pauses while you sleep.
A split night sleep study is an overnight test ordered to diagnose sleep apnea. Sleep apnea is a condition where the back of the throat is blocked (or obstructed) when you are sleeping. If criteria are met, or enough apnea is seen throughout the first half of the night, then you’ll use a continuous positive airway pressure (CPAP) mask and device during the second half of the split night sleep study. The CPAP machine helps to treat sleep apnea by pressurizing air to hold open your airway while you sleep.
PSG is an overnight test ordered to diagnose various sleep disorders.
An MLST is the standard test used to diagnose narcolepsy and excessive daytime sleepiness for which the cause is unknown. The MSLT immediately follows a polysomnogram (PSG), or overnight sleep study.
