Clinical Presentation & History
The bedside nurse hands you the chart. Mr. Youssef Khaled, 58, day 4 of ICU care after multiple rib fractures and pulmonary contusion from a construction site collapse. He was intubated for hypoxemic respiratory failure; his P/F ratio has improved from 140 yesterday to 220 this morning. He just spiked 38.9°C. You cannot obtain history from the intubated patient — you must gather collateral information from the bedside nurse and review the chart.
