Noninvasive Alternatives to Arterial Blood Gases in Obese Patients

Short-term effects of humidification devices on respiratory pattern and arterial blood gases during noninvasive ventilation.

BACKGROUND The impact of humidification devices on ventilatory and arterial blood gases parameters during noninvasive ventilation (NIV) remains controversial. The aim of the study was to compare the short-term impact of heat and moisture exchangers (HMEs) and heated humidifiers (HHs) during NIV for either hypercapnic or hypoxemic acute respiratory failure. METHODS Consecutive subjects receiv...

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...
