the relation between serum osmolality, glucose, sodium, bicarbonate, arterial ph, bun and level of consciousness was studied in 189 patients with diabetic ketoacidosis (dka). there was much overlap between all laboratory values among various groups, even when there was a statistically significant difference. to find a better predictor, we defined a new factor as serum osmolality/arterial ph. th...

With increasing use of arterial blood gas analysis in various ward and other hospital settings to aid medical diagnosis and management, nurses who can interpret results are often able to initiate earlier interventions and understand the reasons for medical interventions. This article enables nurses to interpret such results.

the acid-base status and arterial blood gas change with temperature variation. to determine the changes in arterial ph and pc02, arterial blood samples of 50 neonates with different clinical conditions were examined at temperatures of 35 to 42°c with an increment of 0.5° c, which resulted in two nonlinear equations with perfect fit on data. the temperature correction factors of these equations,...

background: substitution of arterial with venous blood samples to estimate blood gas status is highly preferable due to practical and safety concerns. numerous studies support the substitution of arterial by venous blood samples, reporting strong correlations between arterial and venous values. this study further investigated the predictive ability of venous blood samples for arterial acid-base...

BACKGROUND Arterial blood gases (ABGs) are often sampled incorrectly, leading to a 'mixed' or venous sample. Delays in analysis and air contamination are common. OBJECTIVES We measured the effects of these errors in patients with chronic obstructive pulmonary disease (COPD) exacerbations and controls. METHODS Arterial and venous samples were analyzed from 30 patients with COPD exacerbation ...

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...

1. Previous studies of the ventilatory response to metabolic acidosis have usually considered only patients with arterial blood pH above 7-10. To define the response during more severe acidaemia, arterial CO, tension and pH were measured in fifty-three episodes of diabetic ketoacidosis, including twenty-four with pH below 7-10, and ten with pH below 7.00. 2. The relation between arterial CO, te...

OBJECTIVE To assess the utility of umbilical cord venous blood gas measures for prediction of umbilical artery pH and base deficit acidemia. METHODS A retrospective cohort study was conducted of all singletons with valid paired arterial and venous cord gas samples delivered at our institution from January 2006 to March 2012. Fetal acidemia was defined primarily as cord arterial blood gas pH l...
