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

Annals 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

Frontiers 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 ...

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

Sensors, 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

Measuring Ventilatory Activity with Structured Light Plethysmography (SLP) Reduces Instrumental Observer Effect and Preserves Tidal Breathing Variability in Healthy and COPD

Frontiers in Physiology, 2017
The use of a mouthpiece to measure ventilatory flow with a pneumotachograph (PNT) introduces a major perturbation to breathing (“instrumental/observer effect”) and suffices to modify the respiratory behavior.

Plethysmographic hyperinflation and well-controlled asthma: contribution and limitations of plethysmography [PDF]

Batna Journal of Medical Sciences
Objective: Asthma control is usually assessed through clinical evaluation and spirometry, but these methods may overlook certain abnormalities, particularly air trapping. Plethysmography allows the detection of this pulmonary hyperinflation.

Opto-electronic Plethysmography

, 2002
Recent developments of Opto-Electronic plethysmography allow a noninvasive and accurate measurement of the volume of the chest wall and its different thoraco-abdominal compartments, without any calibration specific on the subject under analysis. OEP provides the complete ventilatory pattern without using any device attached to the subject in any ...
