Itamar Medical

Welcome to a new era of home sleep apnea testing.

ZOLL® Itamar®, a division of ZOLL® Medical, is a leading company in sleep apnea diagnosis and pioneering innovative sleep apnea management programs for patients and healthcare professionals. Their mission is to improve access to the millions of undiagnosed sleep apnea patients with diagnostic testing and cardio sleep solutions through our breakthrough WatchPAT® products and services.

WatchPAT®️ is an innovative Home Sleep Apnea Device (HSAT) that utilizes the peripheral arterial signal (PAT®️) for Sleep Apnea diagnosis.  It measures up to 7 channels (PAT®️ signal, heart rate, oximetry, actigraphy, body position, snoring, and chest motion) via three points of contact. Within one minute post-study, the raw data is downloaded and auto-scored identifying all types of apnea events. WatchPAT®️ provides AHI, AHIc, RDI, and ODI based upon True Sleep Time and Sleep Staging. The WatchPAT®️ Home Sleep Test (HST) is clinically validated with an 89% correlation to PSG 1 . The PAT signal was included in the 2017 AASM Clinical Practice Guidelines as technically adequate.

Its proprietary technology enables the non-invasive recording, measurement and analysis of Peripheral Arterial Tonometry, or the PAT signal. The PAT signal measures changes in a patient’s pulsatile arterial volume, providing a “window” to the cardiovascular system and the sympathetic branch of the autonomic nervous system.
