Prevention of complications such as gastrointestinal hemorrhage, venous thrombosis, and nosocomial infection is a crucial component of the care plan. [accessmedicine.mhmedical.com]
Losing weight may help prevent respiratory acidosis due to obesity (obesity-hypoventilation syndrome). Be careful about taking sedating medicines, and never combine these medicines with alcohol. [medlineplus.gov]
• Overproduction of carbon dioxide is usually matched by increased excretion (due to increased alveolar ventilation) such that hypercapnia is prevented. 6. • Secondary physiologic response – – Respiratory acidosis acidifies body fluids. – It elicits [slideshare.net]
