The Contec CMS50F with integrated Bluetooth is a wrist pulse oximeter designed for continuous overnight sleep studies. This portable oximeter monitor is especially useful in the detection of sleeping conditions like sleep apnea in adults. This monitor records and saves breathing data based on your blood oxygen saturation (SpO2) and your pulse rate. This sleep monitor data recorder is loaded with features that include alarm settings for low levels of SpO2 and pulse rate, data download capabilities using Windows Operating System, reports that include an Excel spread sheet with a second by second values for your pulse and SpO2 that allow you to view numerical values for your vital signs throughout the night. This monitor integrates Bluetooth that lets the user track live results in real time from a detached computer wirelessly. This feature makes the CMS50F a great way to track the vital sign condition of any convalescent adult from the comfort of their own home. The CMS50F gives the user the ability to record, save and download data in your computer for further analysis. This oximeter is highly reliable and accurate. There are many applications for this oximeter, including sleep study, sleep apnea study, endurance and recovery study, monitor the need for oxygen therapy for patients, and monitoring COPD patients oxygen levels. This portable monitor is also very useful for active people that practice high endurance sports. The oximeter is designed for use at home and medical facilities. Pilots and athletes will also find CMS50F helpful during their activities.
