Preoperative “R wave amplitude variation” on electrocardiogram predicts severe hypovolemia

open access: yesAnnals of Cardiac Anaesthesia, 2019
Preoperative fasting is essential to prevent aspiration and associated complications. However, quite often patients end up fasting for 12 h or more due to changes in the operating room schedules, delays, and postponements.

Post-COVID changes in lung function 6 months after veno-venous extracorporeal membrane oxygenation: a prospective observational clinical trial

open access: yesFrontiers in Medicine, 2023
BackgroundSevere coronavirus disease 2019 (COVID-19) may require veno-venous extracorporeal membrane oxygenation (V-V ECMO). While V-V ECMO is offered in severe lung injury to COVID-19, long-term respiratory follow-up in these patients is missing ...

A venous occlusion plethysmography using a load cell as the sensing element [PDF]

open access: yes, 1990
An application of the load cell as a sensor in venous occlusion plethysmography is presented. In this method the limb volume changes that follow venous occlusion are converted into water volume changes using a water tank for volume change detection.

The Impact of Stretching Intensities on Neural and Autonomic Responses: Implications for Relaxation

open access: yesSensors, 2023
Stretching is an effective exercise for increasing body flexibility and pain relief. This study investigates the relationship between stretching intensity and relaxation effects, focusing on brainwaves and autonomic nervous system (ANS) activity. We used

Evaluation of air-displacement plethysmography in children aged 5-7 years using a three-component model of body composition [PDF]

open access: yes, 2003
The aim of the present study was to evaluate air-displacement plethysmography (ADP) in children aged 5-7 years. Body-composition measurements were obtained by ADP, H-2 dilution and anthropometry in twenty-eight children. Calculation of body volume by ADP

Venous occlusion plethysmography vs. Doppler ultrasound in the assessment of leg blood flow kinetics during different intensities of calf exercise [PDF]

open access: yes, 2017
PurposeIt has recently been shown that venous occlusion plethysmography (VOP) can successfully assess the rate of increase in leg blood flow (LBF) (LBF kinetics) responses during calf exercise, but there is lack of data supporting its validity ...

A Novel, Contactless, Portable “Spot-Check” Device Accurately Measures Respiratory Rate [PDF]

open access: yes, 2020
Respiratory rate (RR) is an important vital sign used in the assessment of acutely ill patients. It is also used as to predict serious deterioration in a patient's clinical condition.

Pulse arrival time: Measurement and clinical applications

open access: yesMGM Journal of Medical Sciences, 2022
Pulse arrival time is the time elapsed between the R-wave of electrocardiogram and systolic peak in peripheral pulse obtained by any of the plethysmographic methods.

Waist Circumference and Waist-to-Hip Ratio in Law Enforcement Agency Recruits: Relationship to Performance in Physical Fitness Tests [PDF]

open access: yes, 2020
Law enforcement agencies (LEAs) use tests to assess recruit physical fitness. Body fat can influence test performance but is difficult to measure during academy because of time, equipment constraints, and instructor knowledge.
