Disposable manual resuscitators are commonly used to ventilate patients during cardiopulmonary resuscitation, suctioning, and intrahospital transport, and their clinical performance is critical. ⋯ Resuscitator reservoir style and manufacturer design significantly affect FDO2. Some resuscitator models may not deliver adequate oxygen in certain clinical circumstances. Each institution should evaluate and choose the resuscitator that best fits its needs, while meeting established performance criteria.

We report a case of a previously healthy 41-year-old man who was admitted for progressive dyspnea and cough, which culminated in respiratory failure, shock, and death. Lung and muscle biopsy results were consistent with interstitial lung disease secondary to polymyositis. Polymyositis and dermatomyositis are rare autoimmune diseases that primarily affect the muscles and skin, with frequent extramuscular and specifically pulmonary manifestations. ⋯ Diagnosis of a specific interstitial lung disease relies mainly on high-resolution computed tomography of the chest and on tissue diagnosis. Prognosis depends on the histopathology findings and the specific form of interstitial lung disease and its response to therapy, which consists of high-dose steroids and immunomodulating agents. Unfortunately, patients with polymyositis/dermatomyositis associated with pulmonary complications have a worse prognosis than patients with isolated forms.
