Blood gas analysis for bedside diagnosis

Bedside estimation of nonaerated lung tissue using blood gas analysis.

OBJECTIVES Studies correlating the arterial partial pressure of oxygen to the fraction of nonaerated lung assessed by CT shunt yielded inconsistent results. We systematically analyzed this relationship and scrutinized key methodological factors that may compromise it. We hypothesized that both physiological shunt and the ratio between PaO2 and the fraction of inspired oxygen enable estimation o...

Accuracy of the i-STAT bedside blood gas analyser.

The performance of the i-STAT portable clinical analyser for measuring blood gases and pH was evaluated with reference to a conventional blood gas analyser (ABL520 Radiometer). Ninety-two samples from the routine blood gas analysis laboratory were chosen according to a wide distribution of partial pressure of carbon dioxide (Pa,CO2), partial pressure oxygen (Pa,O2) and pH and then analysed. All...

Bedside Diagnosis

Arterial blood gas analysis.

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.
