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...

arterial blood gas parameters were analyzed in forty-nine healthy persons (31 males, 18 females) to detemine reference values fo these parameters and their relation to the time from last food intake to arterial puncture (t). the mean ± standard deviation of arterial oxygen pressure, arterial carbon dioxide pressure and ph at core body temperature were 84.4±7.0 mmhg (male: 83.0±6.5, female: 86.7...

introduction: arterial gas derangement could change urinary sodium excretion in chronic obstructive pulmonary disease (copd) patients.there are very few and conflicting data in regards to the measurement of fractional excretion of sodium in copd patients. the main aim of this study was to assess the relationship between renal fractional excretion of sodium(fena) with arterial blood gas and spir...

For more 20 years, noninvasive blood pressure (NIBP) monitors have been widely used in operating rooms and critical care units to closely monitor blood pressure in patients of all ages. Despite the widespread use of automated blood pressure monitors, clinicians continue to deliberate over the accuracy and reliability of automated NIBP devices compared to other methods of blood pressure determin...

End-organ damage associated with hypertension is more closely related to ambulatory blood pressure (ABP) than clinic or casual blood pressure measurements. ABP measurements give better prediction of clinical outcome than clinic or casual blood pressure measurements. The technique of ABP monitoring (ABPM) is specialised; validated monitors and appropriate quality control measures should be used....

The main purpose of the leakage detection system on a gas pipeline is to give a warning of the dangers related to a gas leak that could endanger human lives and cause material loss. There is a wide range of gas detection systems used to provide an early detection and warning in the event of a leak in a gas pipeline, one of which that is wired monitoring system. However, in its implementation, t...
