A 77-year-old woman is still intubated and breathing spontaneously following a total hip replacement. The muscle relaxant has been reversed. Tidal volume is 400 ml, end-tidal carbon dioxide tension is 45 mmHg, and SpO2 is 98% at an FiO2 of 1.0. On transfer from the operating table to the gurney, heart rate increases from 65 to 100 bpm and blood pressure decreases from 130/80 to 80/50 mmHg. End-tidal carbon dioxide tension is 30 mmHg and SpO2 is 94%. The most likely diagnosis is
