OBJECTIVE To determine the haemodynamic effects of intensive care physiotherapy after liver transplantation. PATIENTS AND METHODS Thirteen patients were included in the study after liver transplantation. The following physiotherapy programme were applied to the patients in intensive care unit: Respiratory physiotherapy, active joint movements, sitting in bed (first task), sitting at the edge ...

In 12 normal subjects, use of ear densitography permitted measurement of systolic time intervals (STI) during uninterrupted treadmill exercise to over 90 percent maximal heart rate on a modified Bruce protocol. Results for control (sitting leads to standing) leads to end-exercise at 18 minutes leads to 10 minutes' sitting recovery were--heart rate (HR): (77 leads to 861 leads to 171 leads to 98...

The purpose of our study was to search for possible changes in the parameters cardiovascular system adolescents during period from 2004 2020 against background introduction digital technologies into educational environment. Methods: A comparative analysis female and male aged 13.9 15.4 years carried out (57 53 2020). We used a spiroartheriocardiorythmograph allowing recording heart rate (HR) bl...

This study compared sitting on a stability ball (B) to sitting on a chair (C) during arm ergometry to determine the impact on peak VO2, peak heart rate (HR), and exercise intensity prescription. Open-circuit spirometer, blood pressure, and HR were monitored during rest and continuous graded exercise test to exhaustion using an arm ergometer. Twenty-seven apparently healthy adults exercised twic...

Regression equations for heart rate (HR)--ejection time (LVET) relations provide the appropriate factors for predicting or correcting left ventricular ejection time at any HR. We investigated HR-LVET regressions under different conditions common to both physiological and clinical studies of LVET which had been selected because of predictably different physiological responses. Ten normal subject...

The aim of this article was to compare 2 portable devices (a heart-rate monitor and an electromagnetic-coil system) that evaluate 2 different physiological parameters--heart rate (HR) and ventilation (VE)--with the objective of estimating energy expenditure (EE). The authors set out to prove that VE is a more pertinent setting than HR to estimate EE during light to moderate activities (sitting ...

purpose: hypercapnia increases minute ventilation (v’e) with little effect on heart rate (hr), whereas hypoxia may increase hr without affecting v’e. however, the effects of hypercapnia and hypoxia on both heart rate variability (hrv) and the clustering of heart beats during spontaneous breathing (respiratory sinus arrhythmia – rsa), are not clear. methods: in this study, 10 human volunteers br...
