[A new quantitative test for parasympathetic nervous function by means of tear volume measurement--application of electronic resistance measuring device (Periotron)] - PubMed » Because reflex secretion of tears is under the sole control of parasympathetic nervous system, tear volume measurement may be useful as a quantitative test for the parasympathetic nervous function. Recently, an electronic resistance measuring device (Peritron: Harco Electronics) has been applied to … Pubmed.ncbi.nlm.nih.gov

Pulmonary Compliance » The compliance of a system is defined as the change in volume that occurs per unit change in the pressure of the system. In layman terms, compliance is the ease with which an elastic structure stretches. Compliance is, therefore, basically a measurement of the elastic resistance of a system. Pulmonary compliance (C) is the total compliance of both lungs, measuring the extent to which the lungs will expand (change in volume of lungs) for each unit increase in the trans-pulmonary pressure (when enough time is allowed for the system to reach equilibrium) [1]. It is one of the most important concepts underpinning mechanical ventilation used to manage patient respiration in the operating room (OR) or intensive care unit (ICU) environment. To better understand pulmonary compliance, specific terminologies require a brief review. The following formula is useful to calculate compliance: Ncbi.nlm.nih.gov

Measuring resistance using 6221 » Hi guys, i want to measure the resistance between 2 points using my 6221 DAQ card. I've searched through the example finder and i found 3 examples on resistance measurement. Now, since i only need to measure on a single instance value thus i tried using the first one (Acq Resistance Sample.vi). Ho… Forums.ni.com

Pulmonary vascular resistance index: Getting the units right and why it matters » Pulmonary vascular resistance (PVR) and PVR index (PVRI) are key variables in a broad range of contexts, including prediction of outcomes in heart and liver transplantation, determining candidacy for closure of atrial or ventricular septal defects, and… Ncbi.nlm.nih.gov

Fingertip photoplethysmographic waveform variability and systemic vascular resistance in intensive care unit patients - PubMed » Low frequency variability in the fingertip photoplethysmogram (PPG) waveform has been utilized for inferring sympathetic vascular control, but its relationship with a quantitative measure of vascular tone has not been established. In this study, we examined the association between fingertip PPG wave … Pubmed.ncbi.nlm.nih.gov
