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 ...
متن کاملEstimation of arterial PCO2 during high frequency jet ventilation. Studies in the dog.
The arterial to end-tidal PCO2 difference (PaCO2-PE'CO2) was measured in five anaesthetized dogs during controlled ventilation at 0.25 Hz (15 b.p.m.) and during high frequency jet ventilation at 1, 3 and 5 Hz. Because of the slow response of the infra-red carbon dioxide analyser, satisfactory recordings of end-tidal carbon dioxide could not be obtained at frequencies greater than 1 Hz. The inte...
متن کاملEffect 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 ...
متن کاملArterial PCO2 as an index of activity in fibrosing alveolitis.
Alveolar hyperventilation is a characteristic feature of the interstitial lung diseases, yet its pathogenesis remains unknown. We examined the relationship between inflammatory alveolar acinar cell counts and the steady state, resting arterial PCO2 in patients with fibrosing alveolitis. To eliminate the influence of overwhelming mechanical lung restriction or resting hypoxemia, we studied 20 pa...
متن کاملIndirect Estimation of ‐ Stable
It is a well-known fact that financial returns exhibit conditional heteroscedasticity and fat tails. While the GARCH-type models are very popular in depicting the conditional heteroscedasticity, the α-stable distribution is a natural candidate for the conditional distribution of financial returns. The α-stable distribution is a generalization of the normal distribution and is described by four ...
