ABSTRACT
The use of continuous positive airway pressure (CPAP) in asthma has been a point of debate over the past several years. Various studies, including those on animals and humans have attempted to understand the role and pathophysiology of CPAP in patients with either well controlled or poorly controlled asthma. The aim of this manuscript is to review the currently available literature on the physiologic and clinical effects of CPAP in animal models of asthma and on humans with stable asthma.
ABSTRACT
CASE PRESENTATION: A 44-year-old man with a history of coronary artery disease, type 2 diabetes mellitus, and OSA reported progressively worsening dyspnea on exertion over a 6-week period. Outpatient CT angiogram revealed a pulmonary artery filling defect. He was sent to the ED where he was started on a heparin drip for unprovoked pulmonary embolism (PE). Echocardiogram revealed normal cardiac function without evidence of right heart strain. Lower extremity ultrasound was negative for DVT. He improved symptomatically, and no risk factors for PE were identified. He was discharged on apixaban. Five weeks later, the patient returned to the ED with hemoptysis. He reported compliance with anticoagulation and improvement of his dyspnea on exertion. History remained negative for recent travel, trauma, surgery, clotting disorders, thromboembolic disease, and alcohol or drug use. He had a 60 pack-year cigarette smoking history and quit 3 months prior.
