A 34 year-old male presents to your emergency department in moderate respiratory distress. He is conscious and as the nurses are hooking up monitors, you are able to obtain a history of recent sore throat, followed by increasing weakness in his extremities with progressive dyspnea on exertion. Several years ago, the patient underwent a thymectomy and has since been maintained on prednisone 30-mg/day and pyridostigmine 60-mg Q4H. Vitals: pulse 112, blood pressure 110/80 mmHg and respiratory rate of 26/min. His oxygen saturation is 87% on room air. What are your next steps in management?
