Arterial Blood Gases: A Simplified Bedside Approach

Interpretation of Arterial blood gases is an essence of critical care. It helps for the assessment of clinical oxygenation, ventilation and acid-base status in critically ill patients. The four closely inter-related physiological parameters pH, PCO2, HCO3 and PO2 helps to diagnose, monitor and manage the ICU patients. Its correct interpretation and application necessitates the knowledge of basi...

Can 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...

Spirometry 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...
