Abg (arterial Blood Gas)

Arterial Blood Gas analysis typically measures: And may include: These measurements are often used to evaluate oxygenation of the tissues and pulmonary function. pH is a measurement of the acidity of the blood, reflecting the number of hydrogen ions present. Lower numbers mean more acidity; higher number mean more alkalinity. pH is Elevated (more alkaline, higher pH) with: Hyperventilation Anxiety, pain Anemia Shock Some degrees of Pulmonary disease Some degrees of Congestive heart failure Myocardial infarction Hypokalemia (decreased potassium) Gastric suctioning or vomiting Antacid administration Aspirin intoxication pH is Decreased (more acid, lower pH) with: Strenuous physical exercise Obesity Starvation Diarrhea Ventilatory failure More severe degrees of Pulmonary Disease More severe degrees of Congestive Heart Failure Pulmonary edema Cardiac arrest Renal failure Lactic acidosis Ketoacidosis in diabetes pCO2 (Partial Pressure of Carbon Dioxide) reflects the the amount of carbon dioxide gas dissolved in the blood. Indirectly, the pCO2 reflects the exchange of this gas through the lungs to the outside air. Two factors each have a significant impact on the pCO2. The first is how r Continue reading >>

    So when a pt comes in with DKA I know that the pH is low due to the acidic ketone bodies and HCO3- gets low in an attempt to buffer and I can understand how initially the PCO2 is low. BUT for most questions I see, the stem usually refers to stating that the patient is lethargic ...so in that case wont the PCO2 be high due to hypoventilation?

    lethargic is the state of consciousness. patient still can hyperventilate, namely DKA coma is characterized by Kussmaul breathing pattern: rapid and deep

Introduction: Diabetic ketoacidosis (DKA) affects many children with type 1 diabetes. Insulin treatment of DKA is traditionally guided by changes in the blood glucose levels and blood gases, whereas β-hydroxybutyrate (β-OHB)—the main ketoacid causing acidosis—is rarely measured. The purpose of this study was to evaluate if bedside monitoring of blood β-OHB levels can simplify management of DKA through elimination of superfluous laboratory monitoring. Methods: Our emergency department treated 68 children with DKA using a standard protocol with monitoring of venous pH, partial pressure of CO2 (pCO2), bicarbonate, glucose, blood urea nitrogen, and electrolytes (two to 10 time points per patient). Venous β-OHB levels were measured using the Precision Xtra™ meter (MediSense/Abbott Diabetes Care, Abbott Park, IL) and, on duplicate batched serum samples, using a reference laboratory method (Cobas Mira Plus; Roche Diagnostics, Indianapolis, IN). Correlations between bedside meter β-OHB and other parameters were evaluated in a series of general linear models with a time series covariance structure fit using spatial power law. Results: The bedside meter β-OHB levels were signific Continue reading >>

Arterial Blood Gases (blood Gases), Acidosis And Alkalosis

Sample The better choice is the Radial artery. The sample may be taken from the femoral artery or brachial. The tests are done immediately because oxygen and carbon dioxide are unstable. Arterial blood is better than the venous blood. For arterial blood don't use the tourniquet and no pull on the syringe plunger. For venous blood syringe or tubes are completely filled and apply a tourniquet for few seconds. Arterial VS Venous blood Arterial blood gives good mixture of blood from various areas of the body. Venous blood gives information of the local area from where the blood sample is taken. Metabolism of the extremity varies from area to area. Arterial blood measurement gives the better status of the lung oxygenating the blood. Arterial blood gives information about the ability of the lung to regulate the acid-base balance through retention or release of CO2. Precautions for the collection of blood Avoid pain and anxiety to the patient which will lead to hyperventilation. Hyperventilation due to any cause leads to decreased CO2 and increased pH. Keep blood cool during transit. Don't clench finger or fist. This will leads to lower CO2 and increased acid metabolites. pCO2 values are Continue reading >>

    Abstract Current guidelines for treatment of diabetic ketoacidosis (DKA) recommend administration of an intravenous bolus dose of insulin followed by a continuous infusion. This study was designed to investigate whether the initial bolus dose is of significant benefit to adult patients with DKA and if it is associated with increased complications. This was a non-concurrent, prospective observational cohort study of adult patients who presented wi ...
