CPAP Titration Study

What is a CPAP?

CPAP stands for Continuous Positive Airway Pressure. A CPAP is a machine used in treatment of sleep apnea. It consists of a nasal mask, connecting tubing and a pressure generator.

How is a CPAP evaluation performed?

A CPAP evaluation is conducted very much like a polysomnography. All electrodes and equipment used in a routine polysomnography will be used in your CPAP evaluation.

You will be asked to sleep with a mask over your nose. This mask will send a constant stream of room air to the back of your throat. The pressure of the machine will be adjusted through the night to eliminate your apnea and snoring.

How long will the evaluation last?

Your CPAP evaluation will begin at approximately 7:30 p.m. You will be able to shower and leave after you wake up the following morning.

Is the procedure painful?

You should experience no more discomfort than with a routine polysomnography. Some patients are claustrophobic and are frightened by the mask at first. Try to remember that this machine should help you breathe much easier once you are asleep.

What if I have a cold or stuffy nose on the day of the evaluation?

The CPAP will not work effectively if you have a stuffy nose. If you have a cold, please call the Wilson Sleep Lab and reschedule your monitoring. If you have a constant stuffy nose, please contact your physician for a decongestant.

When will I know the results?

The final report of your evaluation will be sent to your physician. You will receive a follow-up appointment with your physician during which the results will be discussed.

What happens if I'm prescribed a CPAP machine for home use?

If you are prescribed a CPAP machine for home use, its pressure will be based on the pressures observed during your CPAP evaluation to eliminate your apnea.
