What to Expect During Your Sleep Study

Several small sensors will be placed on your scalp, face, chest, abdomen and legs. These sensors will monitor your eye movements, muscle activity, brain waves, heart rate, airflow, respiratory effort and oxygen levels throughout the entire night. Equipment is easily disconnected if you need to go to the restroom in the middle of the night. Based on your physician’s order and the finding of the sleep study, sleep therapy (positive airway pressure/PAP) may be initiated in the middle of the night.

You will have a private bedroom and restroom facilities are nearby. The recording equipment is continuously monitored in a separate room throughout the night with a technologist who is always available to assist you. Visual recording of your sleep study may be in progress throughout the night.

Patient Testimonial:
 
"I will be honest. I was a bit apprehensive about the over-nighter. I arrived a little early in Garden Grove and Sara (who was working with another patient) welcomed me and told me she would be with me shortly. She was super professional and put me at ease. She really made a huge difference and I want you to know, you have a great representative there. Best regards, Gunnar S."
