Validation of the capnodynamic method to calculate mixed venous oxygen saturation in postoperative cardiac patients

Intensive Care Medicine Experimental
Background Cardiac output and mixed venous oxygen saturation are key variables in monitoring adequate oxygen delivery and have typically been measured using pulmonary artery catheterisation. The capnodynamic method measures effective pulmonary blood flow

Arterial and Mixed Venous Blood Gas Tensions in Exercising Ducks

Poultry Science, 1980
Adult White Pekin ducks were exercised at three work levels on a treadmill at speeds of .9, 1.47, and 2.16 km/hr for 20 min with a 90 min rest period following each exercise period. Blood gas and pH analyses were performed on samples simultaneously withdrawn from the brachial artery and the right ventricle (as an estimate of mixed venous blood) at ...

Retrograde Cerebral Air Embolism in a Patient with Intestinal Necrosis: A Case Report

Balkan Medical Journal, 2017
Background: Cerebral venous air embolism is a severe clinical condition related to an unfavourable outcome in patients with neurological impairment. Cerebral venous air embolism may occur secondarily to arterial or venous interventions.

A Comparative Evaluation of Venous Blood Gas between Arterial and Venous Blood Samples in Patients of Acute Breathlessness

, 2023
AbstractAim: The aim of the present study was to compare venous blood gas assessments for variables such as pH, pCO2,bicarbonate and base excess between arterial and venous blood samples.Methods: This Prospective study was conducted at ANMMCH Gaya by Department of Emergency Medicine forthe period of 2 years.

Analysis of α-lipoprotein cholesterol in 50 μl of plasma

Journal of Lipid Research, 1974
A micromethod for quantitation of α-lipoprotein cholesterol was devised for gas–liquid chromatography to minimize plasma sample size and facilitate lipid studies using capillary blood from children or small animals. α-Lipoprotein cholesterol was measured

Does traffic‐related air pollution exposure alter blood gas parameters in recreationally trained male cyclists during prolonged endurance exercise?

Physiological Reports
Exposure to air pollution has been a significant challenge in large cities as São Paulo, Brazil, particularly for individuals exercising outdoors. The increasing on ventilation (VE) during physical effort can lead to greater pollutant inhalation.

Prediction of arterial blood ph and partial pressure of carbon dioxide from venous blood samples in patients receiving mechanical ventilation

Journal of Medical Signals and Sensors, 2013
Substitution of arterial with venous blood samples to estimate blood gas status is highly preferable due to practical and safety concerns. Numerous studies support the substitution of arterial by venous blood samples, reporting strong correlations ...

Pulmonary shunt in critical care: a practical approach with clinical scenarios

Journal of Anesthesia, Analgesia and Critical Care
Background Pulmonary shunt refers to the passage of venous blood into the arterial blood system bypassing the alveoli-blood gas exchange. Pulmonary shunt is defined by a drop in the physiologic coupling of lung ventilation and lung perfusion.

Hematology, Biochemistry, and Blood Gas Reference Intervals for Captive Anesthetized Long-Tailed Goral (Naemorhedus caudatus)

Animals
The long-tailed goral (Naemorhedus caudatus) is classified as an endangered species globally, and national projects for conservation are underway in South Korea. However, blood test references would enable comprehensive health assessments in this species.

Venous blood gas in adult patients with diabetic ketoacidosis [PDF]

Emergency Medicine Journal, 2003
A short cut review was carried out to establish whether venous blood gas measurement accurately demonstrates the degree of acidosis in patients with diabetic ketoacidosis. A total of 27 papers were found using the reported search, of which two presented the best evidence to answer the clinical question.
