results fifty-seven patients were enrolled; 35 patients (62.5 %) were male. the mean of etco2 and paco2 of patients were 41.49 ± 9.80 and 64.74 ± 9.76, respectively. the mean of paco2 was significantly more than the means of etco2 in patients with copd. the association between arterial bicarbonate and etco2 was weak and not significant (p = 0.136 and r = 0.04). conclusions capnography can be us...

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...

In addition, due to the nature of ABG testing, clinicians cannot afford to waste time or resources when making decisions based on an ABG sample analysis. To ensure accurate results for such decision-making, it is imperative that the analytical process be as standardized and finely calibrated as possible. For example, variations in technique in the areas of specimen preparation, turnaround time ...

SEVERINGHAUS, JOHN W. Blood gas calculator. J. Appl. Physiol. 21(3): I 108-1 I 16. 1966.-A slide rule is described whose scales yield direct solutions of the following blood gas problems: r) the whole blood oxygen dissociation curve of man with variable temperature, pH, and base excess; 2) the effect of anaerobic temperature change on blood Pea , Pcoz , and pH; 3) the true oxygen consumption fr...

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.

abstract objective: to determine the correlation between blood gas parameters and central venous pressure (cvp) in patients suffering from septic shock. m e t h od s : forty adult patients with diagnosis of septic shock who were admitted to the emergency department (ed) of shohadaye tajrish hospital affiliated with shahid beheshti university of medical sciences, and met inclusion and exclusion ...
