The purpose of the project was to produce an at-home sleep apnea detection device. Now at its completed stage, this device allows physicians to monitor patients’ vital signs during sleep without the high cost of a standard polysomnograph test. Currently, a proper diagnosis for sleep apnea requires at least a one night stay at a hospital or clinic where physicians can monitor the patient, which is both time consuming and expensive for the patient. The convenience to the patient of this laptop sized at-home monitoring system rather than an overnight sleep clinic stay makes this device an attractive solution. The device allows for patients to enjoy the comforts of their own bed and eliminates the need to wear an uncomfortable facemask to measure respiration that would normally be utilized at a hospital. The device also eliminates the need of professional assistance for data monitoring. The patient can record a night’s event with the click of the button. The vital signs monitored by the device include respiration rate, blood oxygen level, heart rate, and blood pressure. The device will monitor the patient’s respiration rate in real time and record the vital signs thirty seconds prior to and after an apnea event occurs. Data from the device is acquired through Labview and stored for later interpretation by a physician. This data can then be analyzed in an interface developed in MATLAB that plots all the parameters for easy diagnosis. Along with the mentioned parameters, the device can easily be modified to monitor the patient sleep position, ECG, and Pulse-ox respiration waveform.
