OSA symptoms can lead to high blood pressure, ischemic heart disease, diabetes, cardiovascular diseases, and even sudden cardiac death due to shortness of breath. Hypoxia can result in cardiac arrest, myocardial failure, circulatory failure, and slowed metabolism. The current treatment for OSA is a ventilator that supplies the patient's lungs with oxygen to improve blood oxygen levels in the body. CheckmeO2 can monitor oxygen saturation for up to 10 hours.
