Sleep disorders are problems associated with sleeping, including difficulty falling or staying asleep through the night, feeling sleepy during the day, or waking up feeling exhausted. Sleep apnea is a common sleep disorder in which breathing stops or gets very shallow during sleep. These breathing pauses last between 10 to 20 seconds or more. Apnea causes sleep disruption as a result of reduced oxygen level in the blood.
Your doctor will diagnose sleep apnea based on your signs and symptoms, your medical and family histories, a physical examination, and test results from sleep studies. Your doctor will make an evaluation and may refer you to a sleep specialist for testing and further evaluation.
Sleep studies monitor what happens to your breathing while you sleep.
Home-Based Portable Monitor: Your doctor may provide you a home based portable monitor to diagnose sleep apnea. These tests usually involve measurement of airflow and breathing patterns. Your doctor may use these results to find out whether you require a full PSG study in a sleep centre.
