Diagnosis of deep-vein thrombosis:comparison of clinical evaluation, ultrasound, plethysmography, and venoscan with X-ray venogram [PDF]

, 1984
In 50 patients with suspected deep-vein thrombosis the diagnostic accuracy of standardised clinical examination, doppler ultrasound, impedance plethysmography, and technetium-99m-labelled-fibrinogen scintigraphy (venoscan) was compared with that of X-ray

A field approach to thoracic impedance plethysmography [PDF]

, 1977
Electrical impedance measurement has not gained wide acceptance as a reliable method for quantifying intra-thoracic events because the mechanisms behind impedance changes are not sufficiently well understood.

Electrical-Impedance Plethysmography - its Use in Studying the Cerebral-Circulation of the Rabbit [PDF]

, 1993
Electrical impedance plethysmography (EIP) is a noninvasive method that may be useful for both the continuous and serial measurement of changes in pulsatile cerebral blood volume and perhaps cerebral blood flow (CBF).

Impact of COVID‐19 on Subsequent Lung Function in Childhood: A Systematized Review

Health Science Reports, Volume 9, Issue 7, July 2026.
ABSTRACT Background and Aims The SARS‐CoV‐2 infection can lead to transiently altered lung function in adults, but data is less clear in children. We aimed to summarize the available evidence about respiratory outcomes after COVID‐19 in childhood. Methods We conducted a literature search on post‐COVID‐19 lung function tests (LFT) on the Medline and ...

A new computerized impedance plethysmograph: accuracy in the detection of proximal deep-vein thrombosis in symptomatic outpatients [PDF]

, 1991
Because of the lack of specificity of the clinical diagnosis it is appropriate in patients with clinically suspected deep-vein thrombosis to apply an objective test before starting anticoagulant treatment.

Non‐Linear Dysanaptic Lung Growth in Patients With Post‐Infectious Bronchiolitis Obliterans

Pediatric Pulmonology, Volume 61, Issue 7, July 2026.
ABSTRACT Introduction Few studies have assessed longitudinal pulmonary function outcomes in post‐infectious bronchiolitis obliterans (PIBO). This study analyzes pulmonary function changes from patients with PIBO at a single center with respect to time and inciting respiratory pathogen.

Postural Influence on Ventilation Efficiency and Relationship With Oxygen‐Enhanced MRI in Cystic Fibrosis

Pediatric Pulmonology, Volume 61, Issue 7, July 2026.
ABSTRACT Background Pulmonary function tests (PFTs) and medical imaging in cystic fibrosis (CF) occasionally show discrepancies in severity levels, potentially due to different postures during testing (seated PFTs and supine imaging). To assess this, we utilised multiple breath washout with Short extension (MBWShX) and oxygen‐enhanced MRI (OE‐MRI ...

Current Practices and Variations Among Pediatric Severe Asthma Programs in the United States—The North American Severe Pediatric Asthma Consortium

Pediatric Pulmonology, Volume 61, Issue 7, July 2026.
ABSTRACT Background Severe and difficult to treat asthma in children is a complex condition causing significant morbidity and associated healthcare costs. While treatment guidelines exist for severe asthma, optimal treatment approaches for the pediatric population are less well established.

Development of Respiratory Monitoring System by Inductive Plethysmography [PDF]

, 1995
The impedance pneumography which is widely used in monitoring respiration is simple to use and noninvasive, but it is sensitive to motion artifacts and insensitive to detect obstructive apnea.

Determinants of Improved Dyspnea and Exercise Tolerance With Nasal High‐Flow O2 Therapy in Fibrotic Interstitial Lung Disease: A Pilot Physiological Study

Respirology, Volume 31, Issue 7, Page 732-744, July 2026.
We tested the respective effect of high‐flow and supplemental O2 from nasal high‐flow O2 therapy (NHFO2) on dyspnea and exercise tolerance in fibrotic interstitial lung disease. Supplemental O2 and NHFO2 (but not high‐flow) provided improvements in these outcomes at “iso‐O2 saturation” due to reduced ventilatory requirements.
