“…Indeed for 8 measurements we observe AE = 0.0, for 6 mesurement AE ≤ 1.0 and for the remaining 7 measurements AE ≤ 2.0. We emphasize that the highest value of AE is still an acceptable, indeed SpO2 is valid if the mean bias is within ±2% [16].…”

“…For example [15] propose a solution based on a mobile phone to detect the color change signal of a fingertip placed in contact with its optical sensor. In [16] a prototype smartphone application (smartphone oximeter) is proposed to measure heart rate and oxygen saturation. In [17] SpO2 measurements are obtained using the built-in sensor and light source of a Samsung Galaxy S8 smartphone.…”

“…7 The use of communication and computer devices to develop measurement and monitoring modules for SpO 2 levels, heart rate, temperature, and other vital signs has contributed to guaranteeing the safety of patients in different ways and places. 8 These personal monitoring systems are not only used when doing physical activities, but they also operate in other states from the daily life of a patient, for example, their implementation in a portable and automated sleep apnea detector to measure SpO 2 . 9 The breakthroughs in the devices connected to the network have managed to increase IoT applications that are currently limited by the structure inflexibility from the existing network.…”

The implementation of the Internet of things in healthcare is a promising challenge to achieve coverage for a bigger number of users in different places at lower costs. Internet of things might mean better technology regarding response time and proper control of medical parameters. This study introduces an Internet-of-things system for healthcare with possibilities to control medical variables according to recent breakthroughs in sensors and data processing. The goal of the system is to optimize the development of applications to obtain variables in real time and with less energy consumption. The proposed model is validated on the measurement and monitoring of oxygen saturation, heart rate, and body temperature in patients with respiratory disorders. This was achieved by the optimization of data acquisition, integrated into a secure architecture using Message Queuing Telemetry Transport protocol. A cloud architecture with interconnection to low-cost and open-source devices was implemented, which interconnect to the sensors and actuators' network. The experimental results were statistically treated against the device pattern data, through hypothesis tests for mean differences to probe the accuracy of the model. Finally, the proposed model demonstrates an efficient performance in several clinical parameters, such as oxygen saturation and heart rate per minute.

“…Despite advances in automation or miniaturization of parts, noninvasive blood pressure monitoring continues to rely on the same principle of collapse and reinflation of an artery then measurement by auscultation [17] or oscillemetry. Pulse oximetry, while now present in most smartphones [18] continues to rely on the same principle of the change in the absorbance of visible and infrared light of hemoglobin at different oxygen saturations [16]. Recent incremental innovations to other vital signs monitoring include new algorithms to better detect heart rate and respiratory rate [14] or the combination of multiple measurement devices into a single, more portable unit [19].…”

Novel wearable and contactless monitoring devices to identify deteriorating patients in the clinical setting: a systematic review protocol

et al. 2020

View full text Add to dashboard Cite

Background: With technological advances, there has been increasing interest in developing contactless and/or non-invasive wearable technologies that continuously monitor vital signs in the clinical setting, and in particular in the deteriorating patient. These devices as of yet have not been well validated in the clinical setting in the clinical ranges observed in a critically unwell patient. We will perform a systematic review of all novel wearable and contactless devices in the clinical setting with focus on degree of novelty and the range of vital signs captured. Methods: Ovid MEDLINE including Epub Ahead of Print and In-Process & Other Non-Indexed Citations, Ovid Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL) Health Technology Assessment (HTA) database (Ovid), CINAHL with Full Text, searches of the grey literature, cited references of eligible studies through Web of Science, and reference lists of eligible studies will be searched. Outcomes of interest will include the quality of studies in relation to reporting guidelines, limitations of non-invasive technology, and application in different clinical populations. We will perform a qualitative assessment of the novelty of the device and discuss its validation in deteriorating patients. Discussion: While novel monitoring devices are often proposed as a solution to problems with infection, discomfort, and frequency of monitoring in the clinical setting it has not yet been established which devices have been validated in clinical settings in the pathological ranges of vital signs that reflect patient deterioration. It is equally unclear what additional value these devices might provide. This systematic review will synthesize published data regarding devices that have been tested and validated in patients AND in a clinical setting AND in reference ranges that reflect severe illness.
