An estimated 40 million people in the U.S. alone are affected by a sleep disorder. About 30 million Americans have undiagnosed Sleep Apnea. Dr. Krehlik uses a portable device to diagnose sleep apnea in the comfort of the patient’s home. For most patients who have snoring, tiredness, headaches or sleepiness an easy to use home sleep test is available. Most patients do not need to go to a sleep laboratory or hospital to be diagnosed.
