This is the first of a two-part unit on arterial blood gas (ABG) analysis, and focuses on background information and basic interpretation of ABGs where no evident compensation is taking place. It discusses the various components on an ABG report, the normal ranges and the significance of abnormal readings. A detailed step-by-step guide to ABG interpretation is available in the Portfolio Pages f...

SPATIAL ARRANGEMENT AS A PART OF GEOSPATIAL FEATURE ONTOLOGIES Jonathan R. Clark, Ph.D George Mason University, 2012 Dissertation Director: Dr. Anthony Stefanidis The geospatial sciences have always employed ontologies to describe spatial data, conduct analysis, and to design the systems and methods for conducting geospatial operations. While research on geospatial ontologies has addressed non-...

The effect of temperature, time of storage, and presence of air bubbles in specimens for blood gas analysis was studied. The results show that air bubbles in a 10% proportion are undesirable because of significant elevation in the PO2, and the storage of anaerobic blood samples at room temperature (25 degrees C) is acceptable when measurements are done within the first 20 minutes.

BACKGROUND Workforce planning in the British healthcare system (NHS) is associated with significant costs of agency staff employment. The introduction of a novel software (ABG) as a 'people to people economy' (P2PE) platform for temporary staff recruitment offers a potential solution to this problem. Consequently, the focus of this study was twofold - primarily to explore the locum doctor lands...

Respiratory system modeling has been extensively studied in steady-state conditions to simulate sleep disorders, to predict its behavior under ventilatory diseases or stimuli and to simulate its interaction with mechanical ventilation. Nevertheless, the studies focused on the instantaneous response are limited, which restricts its application in clinical practice. The aim of this study is doubl...

Poorly organised clinical equipment can waste significant amounts of time otherwise available for direct patient care. As a group of foundation year one doctors, we identified the organisation of clinical equipment across surgical wards at North Bristol NHS Trust to be poor with stocks often low and items frequently difficult to locate. Time-motion studies (n=80) were confirmatory demonstrating...

AIMS To describe the relation between oscillatory amplitude changes and arterial blood gas (ABG) changes in preterm infants receiving high frequency oscillatory ventilation, using a multiparameter intra-arterial sensor (MPIAS). METHODS Continuous MPIAS ABG data were collected after amplitude changes and stratified according to FIO(2): high (> 0.4) or low (< 0.3). For each amplitude change, th...

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 ...
