What are the causes of acute respiratory failure?

Acute respiratory failure can be caused by all that results in insufficient gas exchange in the lungs. When a person breathes, carbon dioxide (CO2) is absorbed from the bloodstream by lungs and oxygen is absorbed into the blood; Insufficient gas exchange leads to high levels of carbon dioxide or low blood oxygen levels. The "acute" refers to an imbalance that develops very quickly and anywhere from a few minutes to an hour. Acute respiratory failure may be caused by injury, disease or problems with blood flow. Hypoxemic failure, known as type 1 respiratory failure, concerns to reduce the amount of oxygen in the blood to pressures less than 60 millimeters of mercury (mmhg). Normal blood pressure in the blood ranges from 85 to 100 mmHg. The main causes of hypoxemic acute respiratory failure are bleeding or accumulation of fluid in the lungs.

Hypercapnic, OR respiratory failure of type 2 is caused by the accumulation of carbon dioxide in the blood. Normal carbon dioxide pressure in the bloodranges from 35 to 45 mmHg; Hypercapper levels are higher, above 50 mmHg. The main causes of hypercaping acute respiratory failure include loss of consciousness, lung disease and hypoventilation or low breathing speed.

Several types of lung diseases can cause acute respiratory failure type 1 and 2. Pneumonia and cystic fibrosis cause the lungs to be filled with liquid. Empy and heavy asthma can result in CO2 accumulation because the lungs or pulmonary cells are blocked. In each of these conditions, blood oxygen levels are exhausted and CO2 cannot be released from the blood.

conditions that reduce blood flow to the lungs such as lung embolism also lead to insufficient gas exchange. Lung embolism is the blocking of pulmonary arteries, so so can not reach lung cells to replace carbon dioxide with new oxygen. High levels of carbon dioxide accumulate in the bloodstream and onThe end reaches the levels sufficiently high for respiratory failure.

injury to specific parts of the body can cause both hypecaping and hypoxemic failure. A heavy wound in the head or alcohol or drug overdose can change the functions of the brain that control the lungs and reduce the respiratory frequency. A heavy chest wound can damage ribs or pulmonary tissue, resulting in incorrect breathing. If the broken rib pierces the lungs, acute airway failure may occur due to bleeding.
