Supplemental oxygen is administered in the vast majority of patients in the perioperative setting and in the intensive care unit to prevent the potentially deleterious effects of hypoxia. On the other hand, the administration of high concentrations of oxygen may induce hyperoxia that may also be associated with significant complications. Oxygen therapy should therefore be precisely titrated and accurately monitored. Although pulse oximetry has become an indispensable monitoring technology to detect hypoxemia, its value in assessing the oxygenation status beyond the range of maximal arterial oxygen saturation (SpO2 ≥97%) is very limited...

BACKGROUND: Remote physiological measurement might be very useful for biomedical diagnostics and monitoring. This study presents an efficient method for remotely measuring heart rate and respiratory rate from video captured by a hovering unmanned aerial vehicle (UVA). The proposed method estimates heart rate and respiratory rate based on the acquired signals obtained from video-photoplethysmography that are synchronous with cardiorespiratory activity. METHODS: Since the PPG signal is highly affected by the noise variations (illumination variations, subject's motions and camera movement), we have used advanced signal processing techniques, including complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) and canonical correlation analysis (CCA) to remove noise under these assumptions...

Contactless detection is one of the new frontiers of technological innovation in the field of healthcare, enabling unobtrusive measurements of biomedical parameters. Compared to conventional methods for Heart Rate (HR) detection that employ expensive and/or uncomfortable devices, such as the Electrocardiograph (ECG) or pulse oximeter, contactless HR detection offers fast and continuous monitoring of heart activities and provides support for clinical analysis without the need for the user to wear a device. This paper presents a validation study for a contactless HR estimation method exploiting RGB (Red, Green, Blue) data from a Microsoft Kinect v2 device...

Pulse oximeters are used to noninvasively measure oxygen saturation in arterial blood (SaO2). Although arterial oxygen saturation measured by pulse oximeter (SpO2) is usually indicated in 1% increments, the value of SaO2 from arterial blood gas analysis is not an integer. We have developed a new pulse oximeter that can measure SpO2 to one digit after the decimal point. The values of SpO2 from the newly developed pulse oximeter are highly correlated with the values of SaO2 from arterial blood gas analysis (SpO2 = 0...

BACKGROUND: The World Health Organisation Surgical Safety Checklist (SSC) improves surgical outcomes and the research question is no longer 'does the SSC work?' but, 'how to make the SSC work?' Evidence for implementation strategies in low-income countries is sparse and existing strategies are heavily based on long-term external support. Short but effective implementation programs are required if widespread scale up is to be achieved. We designed and delivered a four-day pilot SSC training course at a single hospital centre in the Republic of Congo, and evaluated the implementation after one year...

BACKGROUND: At high altitude, prevalence of restless legs syndrome has been found to be greater than expected in small population-based studies, which did not use validated tools for identification of RLS. However, it is not known as to whether this increased prevalence is associated with altitude or increased risk factors for RLS in these populations or errors in identification of RLS. METHOD: This population based, door-to-door study was conducted at low altitude (400 m above sea level) and high altitudes (1900-2000 m and 3200 m above sea level) using random stratified sampling in Himalayan and sub-Himalayan region of India...

BACKGROUND: COPD is a debilitating disease that affects patients' daily lives. One's daily physical activity (DPA) decreases due to multifactorial causes, and this decrease is correlated with a poor prognosis in COPD patients. Muscle wasting may at least be partly due to increased activity of the ubiquitin proteasome pathway and apoptosis. METHODS: This study investigated the relationships among DPA, circulating proteasome activity, and protein carbonyl in COPD patients and healthy subjects (HSs)...
