Simple Rapid Methods of Estimating Arterial and Mixed Venous pCO2

Noninvasive measurement of mixed venous PCO2.

Effect of acute hyperventilation on the venous-arterial PCO2 difference

colleagues [1] in the previous issue of Critical Care. Th e letter suggested that acute changes in the arterial partial pressure of carbon dioxide (PaCO2) can aff ect the venous-arterial diff erence in carbon dioxide tension (ΔCO2). In a study by the authors, 10 ventilated and hemodynamically stable patients were included after elective cardiac surgery. Hypocapnia was induced by increasing the ...

ABC of arterial and venous disease. Non-invasive methods of arterial and venous assessment.

In the simplest form of ultrasonography, ultrasound is transmitted as a continuous beam from a probe that contains two piezoelectric crystals. The transmitting crystal produces ultrasound at a fixed frequency (set by the operator according to the depth of the vessel being examined), and the receiving crystal vibrates in response to reflected waves and produces an output voltage. Conventional B ...

Arterial Pco2 and Cerebral Hemodynamics.

REIVICH, MARTIN. Arterial Pcoz and cerebral hemodynamics. Am. J. Physiol. 206(1) : q-35. rg64.---The effect of arterial Pco:! in the control of cerebral hemodynamics over the full range of responsiveness of the cerebral vasculature was studied in the rhesus monkey. Cerebral perfusion pressure and arterial 02 saturation were controlled so that they produced no significant effect on the cerebral ...
