While wearable sensor systems are now widely used to monitor vital signs in hospitals and at home, most such systems are designed for bedridden patients. In contrast, the use of wireless sensors to capture physiological data from patients for long term health monitoring is becoming increasingly popular although some previous studies recorded complaints from users about discomfort when wearing these. In addition, these systems can sometimes suffer from interference from existing Wi-Fi traffic. Therefore, a sensor system that is both comfortable to use and does not encounter interference with existing wireless traffic is required. This paper presents a system design that includes a probe, sensor, radio, and receiver for a long term heart rate monitoring in a senior center. This system has been deployed in a senior center since May 2012, and 63 seniors have used this system in this period. The senior center has its own wireless network, and no changes were made to this. The monitoring system presented in this work runs together with the existing network, and achieves a 97% packet delivery rate.

Wearable sensor systems are widely used for vital sign monitoring in hospitals, and at homes in recent years. However, most of them are designed for bedridden patients in hospitals. Using wireless sensors to capture physiological data from patients for long term health monitoring in a health institution has become increasingly popular these days. Some previous studies recorded complaints from the users about the discomfort from wearing the devices. In addition, such a system sometimes can be interfered by the existing Wi-Fi traffic. Therefore, a sensor system that is comfortable to use and does not interfere with the existing wireless traffic is required. In this paper we present the system design that includes the probe, sensor, radio, and the receiver, for a long term heart rate monitoring system in a senior center. Our system has been deployed in a senior center since May 2012, and 63 seniors had used this system since then. The senior center has its own wireless network and we made no change to the existing network. Our monitoring system runs together with the existing network, and achieves a 97% packet delivery rate.

“…Over the last decade, there has been considerable increase in interest and research activity in wearable sensors to measure blood oxygen saturation (SpO2) [1][2][3][4][5][6][7][8][9]. The principle of pulse oximetry is typically applied, which assesses the level of blood oxygenation by optical light transmission through the blood (for a review of oximetry techniques and their theory, see Nitzan et al [9]).…”

“…Devices are typically constructed as ring-type sensors, which are controlled using cabled or wireless control units, often with the possibility of connecting to a desktop computer or smartphone using USB cable or Bluetooth technology [1,3]. Other approaches suggested the use of 4G, WiFi, or Zigbee networks to upload data to a server, which could be accessed by remote coaches or doctors [4,8].…”

The study reports about a case of a lung cancer patient with increasing difficulties in falling asleep and frequent periods of wakefulness. Severe dyspnea related to pneumonitis caused as a side effect of immunotherapy worsened the situation. Eventually, fear of falling asleep developed, including panic attacks and anxiety of choking, which was shown to lead to nights of complete wakefulness. The patient did not only sleep poorly; he did not sleep at all at night for several days, as evidenced by the notes he made during the night. Polygraphy showed no evidence of sleep-disordered breathing, but frequent periods of wakefulness and reduced basal saturation around 90% during sleep due to lung changes such as extensive functional failure of the left upper lobe with position-dependent shunts. The authors hypothesized that the symptoms described were causally related to a drop in oxygen saturation in the patient's blood. Therefore, they pursued the goal of finding a measurement technique that is as inexpensive as possible and that the patient can operate without outside assistance and great effort. So the patient started using a low-cost wearable device that allows simultaneous measurements of blood oxygen content, pulse rate and movement intensity. It consists of a finger ring with pulse oximetry sensor and a wristband with the control unit containing a vibration motor. The described device reliably warned of disturbances in oxygen concentration in the blood during the night with its vibration alarm. By use of that device during the whole night at home, the events of reduced oxygen saturation and the anxiety symptoms were reduced. Sleep disturbances with sudden awakenings did not occur when using the device. The patient benefited from the security gained in this way and slept much more peacefully, and he could spend nights without waking up again. In conclusion, wearable oximeters with vibration alarm can be recommended for patients’ home care in lung cancer patients.
