Thus, it should come as no surprise that impaired cognitive function is associated with hypothyroidism and subclinical hypothyroidism. Another common problem during aging is anemia. Sometimes this is due to a loss of blood for various reasons, including stomach infections like h. pylori.
Pulmonary embolism is a blockage in one of the pulmonary arteries in your lungs. In most cases, pulmonary embolism is caused by blood clots that travel to the lungs from the legs or, rarely, other parts of the body (deep vein thrombosis). Because the clots block blood flow to the lungs, pulmonary embolism can be life-threatening. However, prompt treatment greatly reduces the risk of death.
A pulmonary shunt is a physiological condition which results when the alveoli of the lungs are perfused with blood as normal, but ventilation (the supply of air) fails to supply the perfused region.he shunt fraction is the percentage of blood put out by the heart that is not completely oxygenated. In pathological conditions such as pulmonary contusion, the shunt fraction is significantly greater and even breathing 100% oxygen does not fully oxygenate the blood.
