It is classified according to blood gases values: Type 1 Respiratory Failure (hypoxemic): is associated with damage to lung tissue which prevents adequate oxygenation of the blood. Physiology, carbon dioxide retention. Since the third major alveolar gas, nitrogen (N), is inert, any increase in CO 2 is accompanied by a reduction of O 2, unless supplemental oxygen is provided. Chronic respiratory failure … for hypercapnic respiratory failure during the study period, of whom 14 received both NIV and HFNC (7 had HFNC as the initial treat-ment). Some people who have lung disease measure their own oxygen levels at home with a pulse oximeter, but this device cannot detect hypercapnia. This gas diffuses into your bloodstream so that it can be exhaled from your lungs. Respiratory failure is a condition in which not enough oxygen passes from your lungs into your blood, or when your lungs cannot properly remove carbon dioxide from your blood. Worsening symptoms B. Pneumonia. In instances, when hypercapnic respiratory failure is suspected, the levels of thyroid hormone should be detected in order to determine hypothyroidism. 10.
