    Venous blood can once more enter the chest and the heart; cardiac output increases. Return of cardiac output Blood return to the heart is enhanced by the effect of the entry of blood that has been dammed back, causing a rapid increase in cardiac output (24 seconds on). The stroke volume usually rises above normal before returning to a normal level.

    While healthy livers are predominantly oxygenated by portal blood supply, long-standing portal hypertension results in compensatory hypertrophy of and increased reliance on the hepatic artery for oxygenation. Thus, in people with advanced liver disease the shunting of portal blood away from hepatocytes is usually well tolerated.

    First aid at altitude is oxygen at the highest practicable concentration and earliest and largest practicable reduction in cabin altitude. Ground-level 100% oxygen therapy is suggested for 2 hours following type-1 decompression sickness that occurs at altitude, if it resolves upon descent.

  5. Superior vena cava syndrome - Wikipedia

    en.wikipedia.org/wiki/Superior_vena_cava_syndrome

    Superior vena cava syndrome (SVCS), is a group of symptoms caused by obstruction of the superior vena cava ("SVC"), a short, wide vessel carrying circulating blood into the heart. The majority of cases are caused by malignant tumors within the mediastinum , most commonly lung cancer and non-Hodgkin's lymphoma , directly compressing or invading ...

    Vertebral artery dissection is one of the two types of cervical artery dissection.The other type, carotid artery dissection, involves the carotid arteries.Vertebral artery dissection is further classified as being either traumatic (caused by mechanical trauma to the neck) or spontaneous, and it may also be classified by the part of the artery involved: extracranial (the part outside the skull ...

  7. Emergency bleeding control - Wikipedia

    en.wikipedia.org/wiki/Emergency_bleeding_control

    Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation. Blood typically exits the wound in spurts, rather than in a steady flow; the blood spurts out in time with the heartbeat. The amount of blood ...

    Ice can be used to decrease inflammation of sore or injured muscles. Heat can also aid in relieving sore muscles by improving blood circulation to them. While the whole arm generally feels painful in TOS, some relief can be seen when ice or heat is intermittently applied to the thoracic region (collar bone, armpit, or shoulder blades).

    Blood flow restriction training / Occlusion Training (also abbreviated BFR training [1]) or Occlusion Training or KAATSU is an exercise and rehabilitation modality where resistance exercise, aerobic exercise or physical therapy movements are performed while using an Occlusion Cuff which is applied to the proximal aspect of the muscle on either the arms or legs.
