The role of portable high-efficiency particulate air (HEPA) filters for supplemental aerosol mitigation during exercise testing is unknown and might be relevant during COVID-19 pandemic. ⋯ The portable HEPA filter reduced the concentration of aerosols generated during exercise testing by 96% ± 2% for all particle sizes and reduced aerosol room clearance time in clinical exercise testing laboratories. Portable HEPA filters therefore might be useful in clinical exercise testing laboratories to reduce the risk of COVID-19 transmission.

Worldwide, health-care professionals are experiencing unprecedented stress related to the coronavirus disease 2019 pandemic. Responding to a new virus for which there is no effective treatment yet and no vaccine is beyond challenging. ⋯ We explore here, guided by evidence, the concept and features of moral distress and individual resilience. Mitigation strategies involve individual and institutional responsibilities; the importance of solidarity, peer support, psychological first aid, and gratitude are highlighted.

Case Reports
A Woman in Her Late 40s with Hypersensitivity Pneumonitis and Recurrent Pleural Effusions.
A woman in her late 40s with a history of recurrent deep vein thromboses and hypersensitivity pneumonitis (HP) presented to the ED with progressive exertional dyspnea and productive cough. She recently had started oral corticosteroids after HP was confirmed via transbronchial lung cryobiopsy from both the right upper and lower lobes, which showed poorly formed granulomas with mild interstitial and perivascular lymphocytic infiltrates. A causative antigen for her HP was never clearly identified.

A 27-year-old man was hospitalized in the burn unit after sustaining an acute inhalational injury and facial burns after an accidental occupational exposure to an industrial disinfectant consisting of a mixture of hydrogen peroxide (15%-30%), acetic acid (5%-15%), and peracetic acid (5%-15%). He demonstrated cough, shortness of breath, and hoarseness of voice at presentation that had developed 6 h after exposure. In addition to the inhalational injury of the vocal cords and lower airways on bronchoscopy (Fig 1), the patient also was diagnosed with acute inhalational pneumonitis based on the findings of hypoxemic respiratory failure and bilateral perihilar airspace opacities on chest radiography (Fig 2). ⋯ However, symptoms of productive cough and shortness of breath on exertion persisted, and he was rehospitalized 27 days after exposure. He was a nonsmoker with no prior history of atopy, asthma, or lung disease. His medical history was remarkable for hypertension and severe obesity with a BMI of 34.7 kg/m2.
