Polysomnography (PSG) is a sleep test to learn if you have a sleep-related breathing disorder (SRBD), such as obstructive sleep apnea.
is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the informed consent form. You can ask someone else (family member) to sign this form for you if you are not able to sign it or if you are a minor. You have the right to understand your medical care in words you know. Before you sign the consent form, make sure you understand the risks and benefits of what will be done, and your questions are clearly answered.
You will be given information (please see Annex 1) about the test and what will happen.
Write down the correct date, time, and location of your procedure.
Inform your healthcare providers, before the test, about complete details of your current medication (name, dosage, frequency, timings, indication), and get clear information if you must continue them or not the night of admission.
You must bring all your current medicines with you to the hospital on the day of admission.
Healthcare providers will clean your skin to put on the electrodes (sticky pads). Any of the following monitors may be used for your PSG test:
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.
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
Contact Your Healthcare Provider (+971 4 41 44444) If:
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.
You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.
