Comparison of lung volumes measured with computed tomography and whole-body plethysmography – a systematic review [PDF]
Introduction: Whole-body plethysmography is the preferred method for measuring the static lung volumes: total lung capacity (TLC), functional residual capacity (FRC) and residual volume (RV), as it also incorporates trapped gas–a common finding in ...

What does inductance plethysmography really measure? [PDF]
, 1988 Inasmuch as it has been claimed that inductance plethysmography can measure cross-sectional area changes, we tested this assumption. We present experimental and computed relationships between self-inductance (L) of coils and areas (A) included inside ...

Blood flow restriction exercise during microgravity exposure in parabolic flight
Experimental Physiology, EarlyView.Abstract This case report evaluates whether it is possible to perform blood flow restriction (BFR) exercise during exposure to microgravity. The objectives were three‐fold: (1) to determine if a personalised tourniquet system (PTS) hardware technology performs nominally and enables BFR exercise in microgravity; (2) to determine if BFR augments the ...

Diagnostic efficacy of impedance plethysmography for clinically suspected deep-vein thrombosis. A randomized trial [PDF]
, 1985 Impedance plethysmography is an accurate noninvasive method to test for proximal vein thrombosis, but it is insensitive to calf-vein thrombi. We randomly assigned patients on referral with clinically suspected deep-vein thrombosis and normal impedance ...

Experimental Physiology, EarlyView.Abstract Adults >65 years of age experience deleterious health effects during extreme heat events at a greater rate than any other age cohort. The purpose of this study was to identify the effectiveness of acute intermittent hand and forearm (H+F) water immersion and/or chronic (7 week) folic acid supplementation on reducing thermal and cardiovascular ...

Classification of Respiratory Diseases
Current Directions in Biomedical EngineeringContactless measurement methods offer a novel approach to assessing respiratory parameters. This study investigates the feasibility of classifying chronic obstructive pulmonary disease, asthma, and healthy individuals using depth-based plethysmography ...

Experimental Physiology, EarlyView.Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

A Cervical Plethysmography System to Monitor Blood Vessel Pulses on the Neck [PDF]
A cervical plethysmography system has been developed to monitor blood vessel pulses on the neck area and at the same time to record the electrocardiogram signal. The system was tested on subjects in upright (90°) and supine (0°) position.

Haemodynamic responses to head‐up tilt versus lower‐body negative pressure in type 1 diabetes
Experimental Physiology, EarlyView.Abstract Head‐up tilt (HUT) and lower‐body negative pressure (LBNP) both reduce central blood volume but differ in heart orientation and regional fluid shifts. Whether they evoke comparable cardiovascular regulation when matched for preload remains uncertain.
