A 65-year-old woman with a history of COPD was discovered unconscious at home 4 hours ago. She is now intubated and is receiving mechanical ventilation.  A flow-directed pulmonary artery catheter has been inserted. Relevant data below.  Pulse    136/min Blood pressure    76/60 mmHg Pulmonary artery pressure    17/6 mmHg Pulmonary capillary wedge pressure    4 mmHg Cardiac output   3.8 L/min Systemic vascular resistance    1354 dynes/sec/cm-5 Central venous pressure    1 mmHg The most likely cause of this patient’s hypotension is
