base deficit is a non-respiratory indicator of acid base status. aim of this study is to assess relationship between the base deficit value in immediate post operative period of cabg and valvular heart disease with cardiopulmonary and in hospital outcome of patient. a total of 136 consecutive with cabg and valvular heart disease scheduled in study. 20 variables were determined during the pre-in...

INTRODUCTION Glucose control to prevent both hyperglycemia and hypoglycemia is important in an intensive care unit. Arterial blood gas analyzers and glucose meters are commonly used to measure blood-glucose concentration in an intensive care unit; however, their accuracies are still unclear. METHODS We performed a systematic literature search (January 1, 2001, to August 31, 2012) to find clin...

The objective of this study was to measure differences between arterial and venous blood gas parameters and to evaluate whether arterial blood gas values can be estimated from venous blood in Asiatic black bears (ABBs). Twelve healthy captive ABBs (8 males and 4 females; 8-16 years; 76.8-220 kg) were included in this study. The bears were immobilized with medetomidine and zolazepam-tiletamine u...

Arterial blood gas analysis, the focus of this article, provides a fuller and more accurate ”gold standard” assessment of blood oxygenation status. It allows generation, not only of oxygen saturation (in arterial blood) sO2(a), but a number of further oxygen-related parameters, including the partial pressure of oxygen in arterial blood, pO2(a) and the total oxygen concentration of arterial bloo...

background  : on-pump coronary artery bypass graft (cabg) surgery impairs gas exchange in the early postoperative period. the main object on this study was evaluation of changes in arterial blood gas values in patients underwent on pump cabg surgery receiving different dose of intravenous nitroglycerin (ntg). methods : sixty-seven consecutive patients undergoing elective on-pump cabg randomly e...

abstract background: after coronary artery bypass surgery, pulmonary complications and oxygenation disorders are common, which have an important role in mortality and morbidity. different methods are used for the improvement of pulmonary function and oxygenation, of which incentive spirometry (is) has been investigated here. the aim of this study is to evaluate the effects of is on arterial blo...

In adult mammals, arterial blood gases closely reflect lung gas composition, and arterial blood gases can, therefore, be effectively regulated through changes in ventilation. This is not the case among most ectothermic vertebrates, where the systemic and pulmonary circulations are not completely separated, resulting in central vascular shunts. In the presence of a right-to-left shunt (R-L shunt...

Effects of acute hypercapnia on the cardiovascular system (CYS) were studied in the anesthetized cat. After surgery the animal was exposed to a gas mixture of 12% CO2 and 25% O2 in nitrogen, and hypercapnia with low levels of arterial pH (pHa) was produced for 20 minutes. In the second run the same level of hypercapnia was induced by ventilating the same cat from the above gas mixture but ...
