Assessment of blood gas status is important in the management of patients with chronic pulmonary disease. Arterial puncture is often painful and may damage the arterial wall. Measurement of oxygen saturation by transcutaneous oximetry offers a non-invasive alternative to arterial methods but does not allow assessment of partial pressure of carbon dioxide. We have examined the value of oximetry ...

Background: Fetal asphyxia and the consequent neurological damages could be avoided if the risk factors are controlled at earlier stages. Umbilical cord arterial blood gas (UCABG) seems to be related to the Apgar scores, as well as the neonatal morbidity and mortality rates. Therefore, we designed this study to assess the correlation between the Apgar score and UCABG i...

It is now recognized that acute respiratory failure, defined in terms of low arterial oxygen tension and/or C 0 2 retention, is usually a reversible syndrome. This is particularly true when respiratory failure occurs as a consequence of impaired ventilation secondary to central nervous system depression. The early recognition of respiratory failure by widespread utilization of arterial blood ga...

The Terumo Capiox SX18R is a commercially available, low prime, reverse phase, hollow fiber membrane oxygenator. The oxygenator consists of a 1.8 m2 microporous polypropylene hollow fiber bundle, a 2200 cm2 tubular stainless steel heat exchanger, and an open hard shell venous reservoir with integral cardiotomy filter. The Terumo Capiox SX18R oxygenator was evaluated to determine its clinical ox...

We describe the development of a “virtual” blood gas electrode system intended for use during cardiopulmonary bypass (CPB). The electrode functions in real time and predicts the patient’s arterial and mixed venous blood gas results every 500 ms. It takes as its primary inputs the settings of the heart-lung machine (FiO2, sweep gas rate, pump flow) and the patient’s hematocrit and metabolic rate...

Radiometer Blood Micro-system 2 was used in studies designed to, (a) compare the mean blood gas and acid-base values of 38 normal horses and 20 horses with chronic obstructive pulmonary disease (COPD), (b) determine the means and standard deviations of blood gas and acid-base values of Thoroughbred horses in training, and (c) investigate the relationships between clinical data, blood gas values...

background: long surgery causes hypothermia and increased bleeding and can increase the arterial blood lactate levels during anesthesia. it causes cellular hypoxia and its complications. considering the core temperature of the patient during surgery it can prevent hypoxia. this study aimed to compare the effects of different temperatures on the core temperature and the concentrations of lactate...

introduction: controlling and reducing serum uric acid levels may have beneficial effects on blood pressure control. the current study was carried out to assess the effects of allopurinol administration on serum uric acid and arterial blood pressure among the patients under hemodialysis.  methods: this double-blind clinical trial was conducted on 132 hemodialysis patients (two separate groups) ...
