BACKGROUND AND OBJECTIVE: Continuous monitoring of respiratory activity plays an essential role in the detection of respiratory diseases (AS, COPD, etc.). Sleep apnea (SA) is characterized by recurrent upper airway obstruction during sleep associated with arterial blood desaturation, sympathetic nervous system activation, and cardiovascular impairment. Untreated patients with AS have increased mortality rates compared to the general population. This study aims to design a remote sleep apnea monitoring system to ensure patient safety and ease the workload of doctors in the era of Covid-19.
Methods: This study aims to design a remote sleep apnea monitoring system to ensure patient safety and ease the workload of physicians. Our study relates to a new low-cost real-time portable sleep apnea monitoring system using the GSM network (GSM Shield Sim900a). The proposed system is a remote monitoring and patient tracking system to detect the apnea event in real time and to provide sleep position, pulse, respiratory and oxygen saturation information to medical specialists ( SpO2) by making direct contact. As soon as an abnormal condition is detected in light of these parameters, the condition is reported (instantly or in the form of brief reports after sleep) to the patient’s relatives, the doctor’s mobile phone or to emergency medical centers (EMCs). ) via a GSM network to manage the file according to the patient’s emergency status.
RESULTS: A study group was formed of six patients to monitor apnea events (three men and three women) between the ages of 20 and 60 years. Patients in the study group suffered from sleep apnea (SA) to varying degrees. All apnea events were detected and all patients were successfully alerted. In addition, the patient’s parameters were successfully sent to all relatives of the patient. Patients who could not recover from apnea were called via the CALL function, and they were informed of their current apnea event and advised that intervention was required. The proposed system is tested on six patients. The onset of apnea was successfully detected and the SMS/CALL function was activated successfully without delay. During testing, it was observed that while some patients started breathing after the first SMS, others needed the second or third SMS. According to the measurement result, the maximum breathlessness time is 46s in patients, and an SMS is sent every 15s. In addition, in cases where the patient was short of breath for a long time, the CALL function was actively solicited from the patient’s relatives and allowed him to intervene. The proposed monitoring system could be used in both clinical and home settings.
CONCLUSIONS: The follow-up of a patient in real time makes it possible to intervene in the event of unforeseen events on the patient. The proposed work uses an acceleration sensor as a reliable method for monitoring and preventing sleep apnea. The developed device is more economical, comfortable and convenient than existing systems not only for patients but also for doctors. Patients can easily use this device in their home environment, which could result in a more comfortable, easy-to-use, cost-effective, and long-term respiratory monitoring system for healthcare applications.
