A 76-yeаr-оld mаn with а histоry оf chronic obstructive pulmonary disease has been receiving ventilatory support for 4 days after an acute myocardial infarction. The ventilator settings are VT 500 mL, IMV rate 8 breaths/min, FIO2 0.5, and PEEP/CPAP 5 cm H2O. ABG results on these settings are pH 7.37, PaCO2 36 mm Hg, PaO2 78 mm Hg, and SpO2 93%.The patient currently meets all criteria for weaning and is placed on a T-piece. Within 10 minutes he develops restlessness, tachycardia, rapid, shallow breathing, and diaphoresis. The SpO2 drops from 93% to 90%, and the pulmonary artery occlusion pressure rises from 12 to 17 mm Hg. The patient does not complain of chest pain and has no dysrhythmias.What do you think is responsible for the failed weaning attempt?
