Some asthmatics show elevation of the peripheral venous oxygen pressure (PvO2)

Validity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content

Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...

Peripheral venous pressure waveform.

PURPOSE OF REVIEW The focus of intraoperative monitoring is moving away from invasive monitoring. This has been attributed to procedure time, cost, and the known risks, which include carotid artery puncture, arrhythmia, pneumothorax, and infection. Until recently, the venous system's contribution to the circulatory system has been incorrectly identified as being insignificant. This article summ...

peripheral venous pressure as a predictor of central venous pressure in continuous monitoring in children

Renal lymphatic function following venous pressure elevation.

The renal lymphatic system plays an important role in removing excess fluid from the kidneys. Unfortunately, the factors influencing lymphatic flow are difficult to measure. We used a simple model to represent renal lymphatics as a single pressure source (PL) pushing lymph through a single resistance (RL). In anesthetized dogs, we cannulated renal lymphatics and measured lymph flow rate (QL) as...

Influence of tissue pressure on central venous pressure/peripheral venous pressure correlation: An experimental report.

BACKGROUND Peripheral venous pressure (PVP) has been shown to correlate with central venous pressure (CVP) in a number of reports. Few studies, however, have explored the relationship between tissue pressure (TP) and PVP/CVP correlation. METHODS PVP and CVP were simultaneously recorded in a bench-top model of the venous circulation of the upper limb and in a single human volunteer after under...
