I n 1958, James et al recognised that umbilical cord blood gas analysis can give an indication of preceding fetal hypoxic stress. It has since become widely accepted that umbilical cord blood gas analysis can provide important information about the past, present and possibly the future condition of the infant. Umbilical cord blood gas analysis is now recommended in all high-risk deliveries by b...

results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...

N AVERAGE adult at rest consumes approximately A 100 million trillion molecules of oxygen per second; with virtually no capacity for oxygen storage, cessation of oxygen delivery quickly results in irreversible cellular damage. The human cardiopulmonary system functions remarkably well in healthy individuals, maintaining the mitochondrial oxygen tension (greater than 1 mmHg) required for aerobic...

Sodium heparin solution is widely used as an anticoagulant in blood gas analysis. Although alterations in blood gas measureIf heparin makes up 10% or more of the t ments may occur when small sample volumes are diluted by volume of a sample for blood gas anal. heparin,' 2 such errors are generally thought to be of theoretical important errors in the carbon dioxide pressi rather than practical im...

BACKGROUND This work aimed to compare frequency of blood gas measurements per day of mechanical ventilation, occurrence of extreme blood gas CO2 values, and clinical outcomes among ventilated neonates managed with and without transcutaneous carbon dioxide (PtcCO2) monitors. This work also measures agreement between simultaneous PtcCO2 and blood gas CO2 measurements and ascertains factors that a...

Invasive measurement of carboxyhemoglobin (COHb) by blood gas analysis (BGA) is accepted as the standard diagnostic procedure in diagnosis of inhalation injury and carbon monoxide (CO) intoxications. The main disadvantage of BGA with COHb testing is the unavailability in pre-hospital rescue conditions. The non-invasive SpCO analysis using pulse CO oximetry (Rad57, Masimo Corp., USA) represents ...

BACKGROUND The utility of routinely obtaining arterial blood gas analyses (ABGs) prior to extubation in patients who have successfully completed a spontaneous breathing trial is not known. OBJECTIVE Review our practices and determine our extubation success rate with a policy of selective ABG utilization. METHODS Retrospective chart review. RESULTS We reviewed 54 extubations of 52 patients...
