This measurement is often used under treatment with a heart lung machine (extracorporeal circulation), and can give the perfusionist an idea of how much flow the patient needs to stay healthy. Tissue oxygen saturation (StO 2) can be measured by near infrared spectroscopy. Although the measurements are still widely discussed, they give an idea ...
Hypoxemia (also spelled hypoxaemia) is an abnormally low level of oxygen in the blood. [ 1 ] [ 2 ] More specifically, it is oxygen deficiency in arterial blood. [ 3 ] Hypoxemia is usually caused by pulmonary disease.
Hypoxia can be due to external causes, when the breathing gas is hypoxic, or internal causes, such as reduced effectiveness of gas transfer in the lungs, reduced capacity of the blood to carry oxygen, compromised general or local perfusion, or inability of the affected tissues to extract oxygen from, or metabolically process, an adequate supply ...
A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic.
Situations that can cause asphyxia include but are not limited to: airway obstruction, the constriction or obstruction of airways, such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials; from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; environments where sufficiently ...
Blocking or disrupting blood flow to the heart is what causes a heart attack, while blocked or disrupted blood flow to the head causes a stroke. "In low doses, aspirin inhibits platelets and ...
The most common type of tumor of upper respiratory tract is squamous cell carcinoma, with the greatest risk factors for this condition being alcohol and tobacco use, with HPV (genotype 16) being another important risk factor. [5] An epidemiological study of over 5 million cases of head and neck trauma in the United States resulting in visits to ...
