Typically, the standard practice for measuring the arterial blood carbon dioxide tension (PaCO2) during cardiopulmonary bypass (CPB) is to take intermittent blood samples for analysis by a bench blood gas analyzer. Continuous inline blood gas monitors are available but are expensive. A potential solution is the capnograph, which was evaluated by determining how accurately the carbon dioxide ten...

Point-of Care analysis is increasingly being applied in the prehospital scene. Arterial blood gas analysis is one of many new initiatives adding to the diagnostic tools of the prehospital physician. In this paper we present a study on the feasibility of the Radiometer ABL-90 in a ground-based Mobile Emergency Care Unit and report on some clinical situations in which the apparatus has proven ben...

background:  patients undergoing cemented hip hemiarthroplasty may develop bone cement implantation syndrome (bcis) which is a leading cause of intraoperative complications. the purpose of this study was to evaluate cardiovascular changes during cemented hip hemiarthroplasty in elderly patients.   methods:  cemented hip hemiarthroplasty was performed on 72 patients with femoral neck fracture. a...

The objectives of this study were to evaluate the accuracy of blood glucose measurements and to analyze the clinicopathological and experimental factors affecting the accuracy of blood glucose measurement devices. The study enrolled 172 patients who underwent cardiac surgery with cardiopulmonary bypass. Arterial, peripheral, and venous blood samples were collected simultaneously every hour to 1...

A daily dose of 20 mg of protriptyline can improve daytime arterial blood gas tensions in chronic obstructive pulmonary disease (COPD). Its usefulness is limited by anticholinergic side-effects. This study examined whether a daily dose of 10 mg of protriptyline improved daytime arterial oxygen tension (PaO2) and quality of life in patients with stable mild or moderate hypoxaemia caused by COPD....

the objective of this study was to find a relationship between blood gas parameters and thyroid hormoneactivity with ascites syndrome in broiler chickens exposed to cold temperature and receiving a high qualitydiet. one hundred and sixty one-day-old broiler chicks were randomly divided in two equal groups. toincrease the incidence of ascites, chicks of group 1 were fed ad libitum with a higher ...

Until the late 1960's there was a remarkable lack of information on the consequences of asthma on arterial oxygenation [1, 2). Since then, it has been known that arterial blood gas abnormalities can range from overt hypoxaemia, usually associated with hypocapnia and respiratory alkalosis, as shown in acute severe asthma, to mild increases in the alveolar-arterial 0 2 tension difference (AaPo,) ...

Sampling arterialized earlobe blood is thought to be easier and less painful than direct arterial puncture, and to allow measurement of blood gas values during exercise without the need to insert an arterial cannula. However, arterialized earlobe oxygen tension (PO2) often underestimates arterial PO2 at rest, and is not fully validated during exercise. We have therefore conducted a prospective ...

We evaluated whether arterial blood samples for pH and blood gas analysis need to be transported on ice. We found that although the changes in pH, pCO2 and pO2 were greater in samples kept at room temperature versus those kept on ice, the difference was probably not of clinical significance until the period of time after arterial puncture exceeded 20 minutes. We recommend that arterial blood sa...
