Classification of respiratory failure

Answer 1

Answer:

The definition of respiratory failure is PaO27kPa (55mmHg). Respiratory failure is divided into type I and type II. Type I respiratory failure involves low oxygen, and normal or low carbon dioxide levels. Type II respiratory failure involves low oxygen, with high carbon dioxide

Answer 2

Answer:

Causes of Type I respiratory failure: disease that damage lung tissue, including pulmonary oedema, pneumonia, acute respiratory distress syndrome, and chronic pulmonary fibrosing alveoloitis. Causes of Type II respiratory failure: the most common cause is chronic obstructive pulmonary disease (COPD).Respiratory failure is classified according to blood gases abnormalities into type 1 and type 2. Type 1(hypoxemic) respiratory failure: in which PaO2 < 60 mmHg with normal or subnormal PaCO2.In this type the gas exchange is impaired at the level of aveolo-capillary membrane.

Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level. The definition of respiratory failure in clinical trials usually includes increased respiratory rate, abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.
