Venous hemodynamics assessed with air plethysmography in legs with lymphedema

, 2018
This study was conducted to identify specific abnormalities using the results from air plethysmography in legs with lymphedema. A routine air plethysmography exercise protocol was performed in 31 patients with unilateral leg lymphedema, and the results ...

Parapharyngeal Fat Pads as an Obesity‐Related Parameter for Apnea‐Hypopnea Index Severity

Journal of Sleep Research, EarlyView.
ABSTRACT In this study, the association between obstructive sleep apnea severity and the parapharyngeal fat pad volume is examined in a population‐based sample. We included 680 participants who underwent standardised overnight polysomnography between 2008 and 2012 as part of the Study of Health in Pomerania in a sleep laboratory in Greifswald, Germany.

Thoracoabdominal Asynchrony in Healthy Children

Journal of Sleep Research, EarlyView.
ABSTRACT Measuring asynchrony between the thorax and abdomen during sleep provides information about inspiratory effort and upper airway obstruction in children, aiding in the diagnosis of obstructive sleep apnea (OSA). This study aimed to define a normative range for thoracoabdominal asynchrony (TAA) in healthy children by studying polysomnographies ...

Development of a plethysmography system for use under microgravity conditions

, 2018
We present a novel application of strain-gauge plethysmography that is suitable to detect blood volume variations in the human venous system. The plethysmography system uses capacitive sensors that are electrically connected to a portable electronic unit

Differences in Sleep Spindle Characteristics Between Children With Narcolepsy and Those With Other Causes of Subjective Sleepiness

Journal of Sleep Research, EarlyView.
ABSTRACT Central disorders of hypersomnolence are characterised by excessive daytime sleepiness. There has been growing interest in analysing sleep micro‐architecture, to further understand how sleep is affected by these conditions. We investigated if sleep spindle activity differed between children with narcolepsy, idiopathic hypersomnolence (IH) and ...

Comparison of Actigraphy and Polysomnography in a Sleep Centre Cohort

Journal of Sleep Research, EarlyView.
MotionWatch 8 actigraphy correlated most strongly with PSG for total sleep time and showed modest group‐level bias, but wide individual limits of agreement precluded interchangeability. PLMS modified actigraphy‐PSG differences, while recording setting influenced actigraphy‐derived sleep continuity across home and inpatient recordings.

Time‐course analysis of cerebral circulation and cardiorespiratory responses to acute central blood volume reduction in healthy young males

Experimental Physiology, EarlyView.
Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

Plethysmographic and Spirometric Reference Equations for Healthy Algerian Adults Using Lambda-Mu-Sigma (Generalized Additive Models for Location, Scale, and Shape): Comparison with Global Lung Initiative 2012 and Global Lung Initiative 2021 Standards

Journal of Advanced Lung Health
Introduction: Spirometric reference values are essential for diagnosing and managing respiratory diseases. However, existing equations, such as those from the Global Lung Initiative (GLI), may not fully represent North African populations.
