Thanks for your question on Healthcare Magic. I can understand your concern. Respiratory acidosis within swelling all over the body are commonly seen with Cor puomonale. Cor puomonale is right sided heart failure due to pulmonary diseases (most commonly COPD). So if he is smoker then smoking should be stopped immediately. Give him medications and inhalers regularly. Fluid restriction should be done (less than 1.5 liters per day). Salt restricted diet should be followed. Get done adult respiratory vaccines like influenza and pneumococcal. Do regular follow ups with your doctor about his health. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
