Hypophosphatemia and acute respiratory failure in a diabetic patient
- 52 Downloads
A previously healthy 48-year-old male developed diabetic ketoacidosis and severe hypophosphatemia. Within a few hours, acute respiratory insufficiency developed with a marked discrepancy between the pulmonary pathology and the very poor oxygenation seen. We argue that this was due to the effect of hypophosphatemia on respiratory muscle- and heart function and P50, leading to impaired oxygen delivery.
