An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle , [ 1 ] but sometimes the femoral artery in the groin or another site is used.
Acute hypercapnia is called acute hypercapnic respiratory failure (AHRF) and is a medical emergency as it generally occurs in the context of acute illness. Chronic hypercapnia, where metabolic compensation is usually present, may cause symptoms but is not generally an emergency.
Hyperoxia is the state of being exposed to high levels of oxygen; it may refer to organisms, cells and tissues that are experiencing excessive oxygenation, [1] or to an abnormally high oxygen concentration in an environment (e.g. a body of water).
Respiratory alkalosis is a medical condition in which increased respiration elevates the blood pH beyond the normal range (7.35–7.45) with a concurrent reduction in arterial levels of carbon dioxide. [1] [4] This condition is one of the four primary disturbances of acid–base homeostasis. [5]
Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...
But medical interventions and associated measures are only meant to help the mother carry the baby as close to term as possible, because, in the end, "the only complete treatment for preeclampsia ...
Arteriovenous oxygen difference is also used in other areas of study such as medicine and medical research. For example, the a-vO 2 diff has been used to measure cerebral blood flow in comatose patients, assisting with their diagnosis and treatment. [2] The a-vO 2 diff has also been used to determine the effects of physical training in coronary ...
