Your Information

Full Night Combination Test

Split Night Study at Trinity Health is a combination of the full night polysomnogram and the titration study. This is a full night study to determine if you have sleep apnea.

For the first portion of the night, you will set up with all of the wires and monitoring devices identical to a NPSG. You will then be monitored by the sleep technologist. If it is determined that you have sleep apnea and you meet certain criteria, the technologist will wake you up to try the CPAP mask on you. You will wear the CPAP mask for the remainder of the night while the pressure is adjusted to a level that adequately treats your apnea.
