Background and objective Continuous monitoring of breathing activity plays a vital role in the detection of respiratory-based diseases (SA, 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 SA have increased mortality rates compared to the general population. This study aims to design a remote monitoring system for sleep apnea to ensure patient safety and ease the workload of doctors in the Covid-19 era. Methods This study aims to design a remote monitoring system for sleep apnea to ensure patient safety and ease the workload of doctors. Our study focuses on a novel portable real-time low-cost sleep apnea monitoring system utilizing the GSM network (GSM Shield Sim900a). Proposed system is a remote monitoring and patient tracking system to detect the apnea event in real time, and to provide information of the sleep position, pulse, and respiratory and oxygen saturation to the medical specialists (SpO 2 ) by establishing a direct contact. As soon as an abnormal condition is detected in the light of these parameters, the condition is reported (instant or in the form of short reports after sleep) to the patient relatives, the doctor's mobile telephone or to the emergency medical centers (EMCs) through a GSM network to handle the case depending on the patient's emergency condition. Results A study group was formed of six patients for monitoring apnea events (three males and three females) between the ages of 20 and 60. The patients in the study group have sleep apnea (SA) in different grades. All the apnea events were detected, and all the patients were successfully alerted. Also, the patient parameters were successfully sent to all patient relatives. Patients who could not get out of apnea were called through the CALL feature, and they were informed about their ongoing apnea event and told that intervention was necessary. The proposed system is tested on six patients. The beginning moment of apnea was successfully detected and the SMS/CALL feature was successfully activated without delay. During the testing, it has been observed that while some of the patients start breathing after the first SMS, some others needed the second or the third SMS. According to the measurement result, the maximum breathless time is 46 s among the patients, and a SMS is sent every 15 s. In addition, in cases where the patient was breathless for a long time, the CALL feature was actively sought from the relatives of the patient and enabled him to intervene. The proposed monitoring system could be used in both clinical and home settings. Conclusions The monitoring of a patient in real time allows to intervene in any unexpected circumstances about the patient. The proposed work uses an acceleration sensor as a reliable method of the sleep apnea for monitoring and prevention. The developed device is more economical, comfortable, and convenient than existing sy...

Son zamanlarda bütün dünyaya yayılan ve dünya sağlık örgütü tarafından Pandemi (dünya geneli salgın) ilan edilen koronavirüs (Covid-19) salgını nedeni ile solunum cihazlarına olan önem ve ihtiyaç bir kez daha kendisini göstermiştir. Solunum aktivitesinin izlenmesi, Kronik Obstrüktif Akciğer Hastalığı (KOAH) gibi solunum kaynaklı hastalıkların saptanmasında hayati bir rol oynar. Bu çalışmada solunum parametreleri ölçümleri için 6 katılımcıdan oluşan bir çalışma grubu oluşturulmuştur. Her bireyden FVC, VC, MVV, RR ve TV performansı gerçekleştirmesi sağlanmıştır. Ölçümler, medikal spirometre cihazı ile eş zamanlı gerçekleştirilmiştir. Toplamda 1860 veri (VC için 1500, MVV için 360 veri) örneklenmiş ve bütün veriler Matlab programında analiz edilmiştir. Elde edilen sonuçların, birbirlerine oldukça benzer olduğu (MVV için Rmvv=0.998; VC için Rvc=0.997) olduğu görülmüştür. Bu çalışmanın en önemli katkılarından biri de, ölçülen verilerin bilgisayara gönderilebilmesi ve SD karta kaydedilebilmesidir. Böylece standart spirometrelerde bulunan termal yazıcılar ile kâğıt israfının önüne geçilmiş ve veriler dijital ortamda saklanmıştır. Geliştirilen sistem pratik ve düşük maliyetli bir çözüm sunmaktadır. Geliştirilen cihazın biyomedikal cihaz teknolojisinde Koah parametrelerini ölçme kabiliyeti ile önemli bir yer alması beklenmektedir. The importance and need for respirators has once again shown itself due to the coronavirus (Covid-19) epidemic, which has recently spread around the world and has been declared as a Pandemic (epidemic worldwide) by the world health organization. Monitoring respiratory activity plays a vital role in detecting respiratory diseases such as Chronic Obstructive Pulmonary Disease (COPD). In this study, a working group of 6 participants was formed to measure respiratory parameters. Each individual was provided to perform FVC, VC, MVV, RR and TV performance. The measurements were carried out simultaneously with the medical spirometer device. A total of 1860 data (1500 data for VC, 360 data for MVV) were sampled and all data were analyzed in Matlab program. It was observed that the results obtained were quite similar to each other (RMVV=0.998 for MVV; RVC=0.997 for VC). One of the most important contributions of this study is that the measured data can be sent to the computer and saved to the SD card. Thus, with the thermal printers in standard spirometers, paper wastage was prevented and the data was stored in digital environment. The developed system offers a practical and low cost solution. The developed device is expected to take an important place in biomedical device technology with its ability to measure COPD parameters.
