hemodynamic monitoring is needed in up to 58% of patients presented to the emergency department. central venous pressure (cvp) monitoring is generally useful to assess general volume status. there are several methods of cvp measurement, which can be categorized as invasive and non-invasive. cvp manometer and electronic transducer are among the invasive methods and direct observation, ultrasonog...

Venous occlusion plethysmography is commonly used as a tool to assess BF (blood flow) and VR (vascular resistance) at baseline and during PORH (post-occlusive reactive hyperaemia). However, little is known about the reproducibility of this method. The purpose of the present study was to investigate short- (hours) and medium (week)-term reproducibility of forearm, calf and thigh BF and VR at bas...

INTRODUCTION Pulmonary function tests allow an objective assessment of the degree of bronchial obstruction in collaborative subjects. The measurement of airway resistance using passive methods is very helpful in non-collaborative subjects. The objective of this study was to assess the applicability of measuring airway resistance by the interrupter technique (Rint) in pediatric subjects, determi...
