Arterial blood gases and acid-base balance in normal children.
Robinson (1) studied the effect of age on the arterial blood gases and the acid-base balance of normal males from 5 to 91 years of age. In addition to the well known increase in oxygen combining capacity which occurs during childhood and adolescence, Robinson found moderately lower mean values for hemoglobin saturation in adults above 40 years of age, and slightly higher mean values for arteria...
متن کاملCan Venous Blood Gases Replace Arterial Blood Gases in Diabetic Ketoacidosis/Renal Failure Induced Metabolic Acidosis?
The study aims to identify the correlation between arterial and venous blood gas variables, in patients with metabolic acidosis secondary to renal failure and/or diabetic ketoacidosis(DKA). Paired arterial and venous blood samples of 100 patients, with metabolic acidosis resultant to renal failure and/or diabetic ketoacidosis during 2009-2011, were analyzed and the correlation between the varia...
متن کاملSpirometry and arterial blood gases in acute severe asthma
Background: We studied in a group of patients admitted for acute severe asthma (ASA) arterial blood gases at admission and it relationship with airway obstruction. We also compared arterial gases of a subgroup of patients unable to perform spirometry because their poor clinical status with those able to complete the test. Methods. Data from arterial gases and spirometry were obtained from two p...
متن کاملEvaluation of a mathematical model for blood gases and acid–base status during extracorporeal circulation
Results Surfactant properties did not change in the control group. In the CPB group, PL content increased in TA 24 hours after CPB. LA concentration dropped 4 hours after CPB (P < 0.01) but recovered within 24 hours. The PL : protein ratio of LA was decreased at 24 hours as compared with baseline (P < 0.01). The relative amount of phosphatidylglycerol in LA-PL content dropped linearly over time...
متن کاملHuman Cerebral Arterio-venous Vasoactive Exchange during Alterations in Arterial Blood Gases Running Title: Cerebral Vasoactive Agents and Arterial Blood Gases
Cerebral blood flow (CBF) is highly regulated by changes in arterial PCO 2 and arterial PO 2. Evidence from animal studies indicates that various vasoactive factors, including release of noradrenaline, endothelin, adrenomedullin, C-natriuretic peptide (CNP) and nitric oxide (NO), may play a role in arterial blood gas-induced alterations in CBF. For the first time, we directly quantified exchang...
