It’s estimated that 54 million to 60 million people have sleep apnea in the United States, and 80% of these people are going undiagnosed and untreated. Economically, sleep apnea also costs the U.S approximately $149.6 billion annually. Home sleep apnea testing (HSAT) helps with this burden because it makes testing more accessible to everyone, especially during a pandemic, when visiting a sleep lab might not be a priority or a possibility for people. Itamar Medical, a digital health and home sleep testing company, has developed a noninvasive method of testing called Peripheral Arterial Tonometry to test patients for sleep apnea in their homes. The technology measures blood volume changes that occur during apnea events—all through the patient’s finger. CEO Gilad Glick sat down with HomeCare to tell us more.
