This forces the patient to wake up continuously, preventing them from getting a good night’s sleep. Sudden changes in this blood oxygen level have been found to be the most accurate indicator of the presence of sleep apnea where an individual’s breathing stops temporarily while asleep. This shines light onto the finger and from the intensity of reflections determines the oxygen saturation level of the blood (SpO2). The device records photoplethysmography (PPG) readings using a 50Hz optical reflective sensor. Both take the form of a small, wearable finger sensor. There are two versions of the NightOwl – a three-day rechargeable or a 10-night disposable model.
The NightOwl home sleep test sensor uses Nordic Semiconductor’s nRF52832 and nRF52810 SoCs, depending on the model. The NightOwl now enables you to get a sleep study on the very night you meet with your physician, and the results are made available to them immediately upon completing the study, dramatically shortening the treatment cycle and getting you on your way to a better nights sleep.Belgian start-up, Ectosense, has developed a finger sensor to determine if sleep apnea is the cause of fatigue. While some sleep issues do require the capabilities of an attended, overnight sleep study, the vast majority identify a condition known as obstructive sleep apnea (OSA) where you stop breathing for periods of 10 seconds or more - sometimes much longer - leading to drops in your blood oxygen level and numerous complications that arise from this highly repetitive cycle, many being very harmful and potentially deadly. They were also very obtrusive, typically requiring up to 13 electrodes to be placed on your body, while you tried to sleep in a strange environment, while being watched on closed circuit TV, making it very difficult to get a truly representative night's sleep. Sleep Studies historically took weeks or months to schedule, required an overnight stay in a hospital or sleep lab, and cost thousands of dollars.
When the battery is depleted, throw it away. There is no need to return the device, recharge the battery, be concerned out disinfecting it or return to the Doctors office to initiate future studies as it is all able to be done remotely from home. Initial and subsequent studies are easily initiated by eMail which contains a link to seamlessly activate the NightOwl. This provides you unprecedented ease, efficiency and economics of determining how well any needed therapies, or changes in health or lifestyle may affect your patient's Sleep Apnea. This can be done at any point over the 3-5 year battery life. Powered by a lithium battery, the NightOwl isREUSABLE with the ability to monitor up to 100 hours of data, enabling you to obtain an assessment of your sleep over multiple nights for the most realistic depiction of your sleep patterns. This makes self-administering the study about as easy as putting on a band-aid. Held in place with a simple adhesive strip, the device transmits its findings wirelessly to the nearby cell phone, which then transmits the recorded data directly to your physician the next morning. Harnessing the connectivity of bluetooth, the internet and smartphones, the tiny NightOwl sensor is activated and placed on the fingertip, using light transmission to monitor tiny yet identifiable changes in the vessels in the distal tip of the finger.
