Healthcare providers will monitor your sleep for the whole test. CPAP (Continuous Positive Airway Pressure) may be needed if your healthcare provider chooses to do a split night test (with and without CPAP). A CPAP machine is used to keep your airway open during sleep. With CPAP, you wear a mask over your nose and mouth or just your nose. The mask is held in place by soft elastic straps that go around your head. The mask is hooked up to the CPAP machine. The machine blows a gentle stream of air into the mask when you breathe. The stream of air helps to keep your airway open, so you can breathe more regularly.
What Will Happen
Your hospital PSG test will be done in a sleep room that looks like a bedroom. Healthcare providers will monitor your sleep for the whole test. When the test is over, the electrodes will be taken off. You may be able to take a shower if you choose. You will then be able to go home. The results of your PSG test will be given to you at your follow-up visit.
If your PSG test is done in your home, you may need electrodes put on at the hospital first. Healthcare providers will tell you how to set up your monitor. They may also tell you what position to sleep in. If someone will be helping you at home, bring them with you so they understand the instructions

Having a sleep-related breathing disorder (SRBD) may make it hard to do normal activities such as work and school. SRBDs cause daytime sleepiness which may lead to car accidents or other injuries. SRBDs that are not treated may cause more severe health problems. Untreated SRBDs may cause high blood pressure, heart disease, and stroke. You may need two or more PSG tests while healthcare providers treat your breathing problem.
