This … WebBecause oxygen completely saturates hemoglobin after only a fraction of the time that blood is in contact with alveolar gas, hypoxemia due to impaired diffusing capacity occurs only when cardiac output is increased (eg, during exercise), when barometric pressure is low (eg, at high altitudes), or when > 50% of the pulmonary parenchyma is destroyed.
WebThe alveoli in the lungs are responsible for gas exchange (they move oxygen to the capillaries and pick up carbon dioxide from the blood to the breathed out). Due to the scarring of the lung tissue in PF, this process can not be carried out properly. This leads to the many symptoms of PF including shortness of breath and a dry cough.
