PURPOSE The purpose of this study was to assess the effects of hyperventilation on patients undergoing laparoscopic surgeries on haemodynamics, partial pressure of carbon dioxide and acid base status. METHODS 60 patients undergoing laparoscopic surgeries under General Anaesthesia were randomized into two groups, "control group" ventilated with tidal volume of 10 ml/kg and respiratory rate of ...

The heterogeneous reaction CO + O + COZ on water ice and various inorganic oxide (Si02, A1203, Fe203, Fe304, CaO, MgO, and Ti02) surfaces has been investigated in order to evaluate the proposition that this heterogeneous reaction may contribute to the COZ stability in the Martian atmosphere. The reaction probabilities were measured at both 196 K and 294 K by using a fast flow-tube reactor coupl...

In a steady state the rate of removal of COz from the blood into the alveoli equals its rate of removal from alveoli to atmosphere. There is a gradient of COz concentration from mixed venous blood to alveolar gas or arterial blood and then to mixed expired gas. The mixed venous to alveolar (or arterial) difference depends upon cardiac output (Fick) and the alveolar (or arterial) to mixed expire...

Aim: This study investigated common fish assemblages in four aquatic stations (Gbaji, Topo, Agboju and Ajegunle) relation to physico-chemical parameters of its water as well simulates numerical values the for year 2024.
 Methodology: Data were collected computed using standard methods algorithm machine learning model respectively. Statistical tools employed include ANOVA Pearson correlatio...

The authors studied the effect of changes in arterial carbon dioxide tension on plasma tidocaine concentrations dltring a constant lidocaine infusion in eight healthy volunteers. With a PaC02 of 41.4 : 0.9 mmttg (mean • SE). total plasma lido. caine concentrations were 3.97 ~0.20 tzg.ml t. There was no significant change associated with hypercarbia (PaCO 2 = 55~7 • 1.5 mmtfg, lidoeaine = 3.93 •...

In a previous paper (Schaefer et al., 1955) it was reported that incubation in air with increased CO2 content enhances the growth of many strains of tubercle bacilli on oleic acidalbumin agar medium. Two of our stock laboratory strains, Vall6e (bovine) and H37Rv (human), showed diminished growth or even no growth when incubated under a C02-enriched atmosphere on this medium.' Occasionally, howe...
