Impedance plethysmography and thrombo-embolic disease
The British Journal of Radiology, 1992 Abstract This study compares the results of impedance plethysmography with lower limb venography in 68 patients referred for investigation of clinical deep vein thrombosis, and with the results of ventilation/perfusion isotope scans in 125 patients with suspected pulmonary embolism. Impedance plethysmography had a sensitivity of 100% and

Heart rate estimation in intense exercise videos [PDF]
arXiv, 2022 Estimating heart rate from video allows non-contact health monitoring with applications in patient care, human interaction, and sports. Existing work can robustly measure heart rate under some degree of motion by face tracking. However, this is not always possible in unconstrained settings, as the face might be occluded or even outside the camera. Here,

Reference values of impulse oscillometric lung function indices in adults of advanced age. [PDF]
, 2013 Impulse oscillometry (IOS) is a non-demanding lung function test. Its diagnostic use may be particularly useful in patients of advanced age with physical or mental limitations unable to perform spirometry.

Issues Determining Direct Airways Hyperresponsiveness in Mice
Frontiers in Physiology, 2012 Airways hyperresponsiveness (AHR) is frequently a primary outcome in mouse models of asthma. There are, however, a number of variables that may affect the outcome of such measurements and the interpretation of the results.

Ventilation inhomogeneity in patients with cystic fibrosis measured by electrical impedance tomography [PDF]
, 2012 Objective: The distribution of ventilation within the lung is inhomogeneous. We hypothesized that the degree of inhomogeneity in patients with cystic fibrosis (CF) differs from that in healthy subjects.

Comparison of Bioelectrical Impedance Analysis and Air Displacement Plethysmography
International Journal of Morphology, 2019 The measurement of body composition has become an important component in the diagnosis of health, physical conditioning and nutritional status. The aim of this study was to compare two methods of detecting body composition, bioelectri cal impedance and ...

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 206-214, April 2025.Abstract Objective Antiphospholipid antibodies (aPL) are recognized to have a pivotal role in recurrent pregnancy loss (RPL) and cardiovascular disease. Therefore, we assessed the vascular function of women with RPL and examined the association with each type of aPL.

Random scattering by rough surfaces with spatially varying impedance [PDF]
Progress In Electromagnetics Research M, Vol. 100, 237-245, 2021, 2019 A method is given for evaluating electromagnetic scattering by an irregular surface with spatially-varying impedance. This uses an operator expansion with respect to impedance variation and allows examination of its effects and the resulting modification of the field scattered by the rough surface.

The Journal of Clinical Pharmacology, EarlyView.Abstract Seizures are the most common neurologic emergency in neonates and are associated with significant morbidity and mortality. Current first‐line pharmacotherapy, phenobarbital, is associated with serious adverse effects, including impairment of the developing brain.

Acta Paediatrica, Volume 114, Issue 5, Page 863-876, May 2025.Abstract Aim Advances in perinatal medicine from 1980 to 2000 improved survival in extremely preterm (EP) neonates. Long‐term effects of these developments remain unclear, and we aimed to investigate potential cohort effects on adult lung function. Methods Three 18‐year‐old population‐based cohorts born at ≤28 weeks gestation or with birthweight ≤1000 ...
