Arterial blood gases: The investigation and analysis of the results

Arterial blood gas sponsored by the arterial blood gas test, partial pressure of oxygen, carbon dioxide, hemoglobin saturation with oxygen and pH in arterial blood. To take the sample, a superficial artery must be found and usually in the wrist or elbow area, and in very few cases at the top of the thigh, a thin needle is placed and about 2 milliliters of blood in a syringe containing a small amount of heparin, a substance containing blood clot. The sample takes a website of the artery and not of the vein; For what is meant to examine these compounds in the blood when left of the lungs and the heart, and before the gases are exchanged in the tissue. When should the doctor be informed? Since we have often collected a blood sample from one of the veins before, the hemorrhagic artery is usually off the wrist, and the poetic blood taken from the heel can be used for children. There are usually no special preparations for the investigation, but if the patient takes oxygen therapy, the treatment can be stopped for 20-30 minutes before undergoing the investigation. General warnings As the blood sample was taken from the artery and not out of the vein, the risk of bleeding is greater compared to taking it intravenously, so it should be pressed on the tingling area for about five minutes. Children and babies are not special problems or consequences, but in the event that the child cries heavily during a needle tingling, respiratory alkaline can occur. Medicines affecting the results of the anesthetics and bicarbonate can have caused the respiratory center and caused respiratory acid, while sodium bicarbonate and potassium oxalate can cause metaboliculi. Natural pronunciation results for arterial blood gases are as follows: Partial pressure of oxygen (PO2): 100 – 75 mm mercury. Partial pressure of carbon dioxide (PCO2): 35-45 mm mercury. Blood acidity (pH): 7.45 – 7.35. Blood saturation (SAO2): 100% – 94%. Bicarbonate (HCO3): 26-22 microscopes per liter. Cases of disturbance of these normal levels can be explained by the following: Reduced hemoglobin saturation in oxygen or low oxygen pressure in the arterial blood to the following: a lack of oxygen that can occur for individuals living in the highlands. Lung diseases. The increased concentration of carbon dioxide in arterial blood indicates a chronic obstructive pulmonary disease, such as: bronchitis. Acute asthma. The decrease in the concentration of carbon dioxide in arterial blood indicates the following: anxiety. Serious tension. High blood acid, that is, less than 7.35, and the concentration of high carbon dioxide, ie more than 45 millimeters mercury, means that the patient is suffering from respu -acidosis, can be caused by chronic obese pneumonia, such as: bronchitis. Acute asthma. pneumonia. Nerve disease. Dysfunction in the function of the thoracic wall that prohibits breathing properly. High blood acid, that is, less than 7.35, and a low bicarbonate concentration, that is, less than 24 microcons per liter, means that the patient suffers from metabolic acidosis, which may indicate the following: Serious diabetes leading to the occurrence of diabetic keto-diabetic ketoasidosis. Milksidosis due to shock. Serious infection. Acute malnutrition. Dehydration. A serious kidney function. Low blood acidity, ie higher than 7.45, and carbon dioxide concentration less than 35 millimeters mercury means that the patient is suffering from a respiratory alkalosis: Salicalalate. Anxiety. Fever. Hyperthyroidism. Pulmonary Embezzze. Low blood acid, ie higher than 7.45, and a bicarbonate concentration above 28 microscopes per liter indicate the following: Metabolic alkalosis. Vomiting. Aspiration. Intestinal blockage. Potassium loss. Production of excess sodium bicarbonate. Liver failure.
