background: the aim of this study was to evaluate the efficacy of arterial blood gases (abgs) in determining the type of intoxication. methods: medical charts of all patients who had referred to the toxicology ward of baharloo hospital between january 2009 and december 2009 were evaluated. after excluding the patients with multi-drug toxicity, data, including age, sex, type of intoxication (the...

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...

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...

conclusions propofol provided a safe and acceptable sedation for post-cabg surgical patients, significantly reduced the requirement for analgesics, and allowed for more rapid tracheal extubation than midazolam but did not result in earlier icu discharge. results the depth of sedation was almost the same in the two groups (rss=4.5 in midazolam group vs 4.7 in propofol group; p = 0.259) but the t...

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...

Objective: Chloride is the major plasma anion. There are several methods available for the determination of serum chloride levels. Unfortunately these methods are sometimes not available in the urgent setting where values are needed. Here we describe...

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 ...
