ZOLL offers best-in-class solutions for sleep apnea diagnosis and treatment. WatchPAT® is an innovative Home Sleep Apnea Test (HSAT) that utilizes the peripheral arterial tonometry signal for sleep apnea diagnosis. The remedē® System is an innovative implantable device that treats adult patients with moderate to severe central sleep apnea.

Do you know the consequences of undiagnosed sleep apnea?

Untreated sleep apnea may increase the risk of high blood pressure, heart attack, stroke, obesity, diabetes, and other medical conditions.1 It may also increase the risk of heart failure or worsen existing conditions and increase the likelihood of arrhythmias, or irregular heart beats, including atrial fibrillation (AF). Patients with sleep apnea have four times the risk of developing AF.2

About Obstructive and Central Sleep Apnea

Sleep apnea is a common disorder in which a patient experiences pauses or shallow breathing while they sleep. There are two main types – Obstructive Sleep Apnea (OSA) and Central Sleep Apnea (CSA) – and a patient can have both.

OSA is caused by a collapse of the airway that occurs during sleep. CSA occurs when the brain fails to send a signal to the body to take a breath. Breathing pauses can occur several times per hour. These repeated pauses prevent the patient from reaching deeper sleep stages, causing poor quality of sleep and stress on the body.

WatchPAT Home Sleep Apnea Test

WatchPAT is a revolutionary FDA-cleared home sleep apnea test that uses innovative technologies to detect sleep apnea. Unlike more complicated diagnostic devices, WatchPAT is an easy-to-use, accurate, and reliable home sleep apnea test (HSAT).

WatchPAT was designed with patient use in mind for “in-home” sleep apnea testing in the comfort of your own bedroom. This environment is more representative of your sleep habits. The WatchPAT home sleep device’s simple operation, and robust noninvasive design, ensure the best possible sleep experience.

*The WatchPAT® is not intended to be used as a diagnostic device for any cardiac arrhythmia and is not intended to replace traditional methods of diagnosis for cardiac arrhythmias. In cases where the longest AFib episode detected is shorter than 60 seconds, review of the PAT® signal for an irregularly irregular rhythm in the location of the episode is recommended. The WatchPAT® may not detect short AFib episodes (<60 seconds).="">
