The present invention involves methods for the treatment of chronic hypoxemia, COPD and lung fibrosis in patients with both COPD and pulmonary fibrosis, and in patients with idiopathic pulmonary fibrosis without COPD, by stimulating the synthesis of human and animal patient lung and sinus surfactants to increase lung functions, prevent hypoxemia while reducing the sinus and lung infections, reducing some drug side effects, inhibiting fibrosis and reducing coughing and nasal erythema. These methods include the following steps: A) analyzing and diagnosing a patient with a lung ailment selected from the group consisting of i) both COPD and pulmonary fibrosis； and ii) idiopathic pulmonary fibrosis without COPD； and, B.) treating the patient to raise the patient's lung functions including FEV1/FVC ratio by contacting mammalian cells with a therapeutically effective amount of a treatment composition that includes a therapeutically effective amount of each constituent of the composition, the composition including the following constituents: a) a pyruvate salt； b) a phosphate； c) a salt of calcium； and d) a salt of magnesium.
