Implantable Impedance Plethysmography [PDF]

open access: yesSensors, 2014
We demonstrate by theory, as well as by ex vivo and in vivo measurements that impedance plethysmography, applied extravascularly directly on large arteries, is a viable method for monitoring various cardiovascular parameters, such as blood pressure, with

Assessment of the Peripheral Microcirculation Using Computer-Assisted Venous Congestion Plethysmography in Post-Traumatic Complex Regional Pain Syndrome Type I [PDF]

open access: bronze, 2001
In complex regional pain syndrome type I (CRPS-I), edema of the affected limb is a common finding. Therefore, the changes in macro- and microcirculatory parameters were investigated to elucidate the underlying pathophysiology.

Toe digit pulsation measurement by impedance plethysmography in miniaturized devices: An early feasibility test [PDF]

open access: goldJournal of Electrical Bioimpedance
This early feasibility test explores impedance plethysmography (IPG) for detecting toe pulse waves using a setup suited for miniaturized devices. Conventional tests often miss micro-circulatory impairment, which is critical for wound healing and limb ...

Chronic intermittent hypoxia‐mediated cognitive dysfunction in ovariectomized rats [PDF]

open access: yesExperimental Physiology
Obstructive sleep apnoea (OSA) is a prevalent cardiorespiratory disorder associated with significant neurocognitive consequences. Despite the higher prevalence of OSA in men, there is a strong association between OSA and Alzheimer's disease (AD), which ...

Different perspectives for monitoring nociception during general anesthesia [PDF]

open access: yesKorean Journal of Anesthesiology, 2022
Safe anesthesia is achieved using objective methods that estimate the patient’s state during different phases of surgery. A patient’s state under anesthesia is characterized by three major aspects, which are linked to the main effects produced by each of
