The efficacy of an oxygen mask with reservoir bag in patients with respiratory failure.
Oxygen masks with reservoir bags (OMR) are widely used for oxygen therapy in patients with severe respiratory failure. The purpose of the present study was to determine whether OMRs are effectively used in clinical practice. ⋯ Fixing an OMR very tightly to the face is mandatory for its effective use. It should also be kept in mind that there are limitations to the efficacy of OMR, even when they are used with such careful management.

Case ReportsA case of juvenile primary pulmonary malignant fibrous histiocytoma.
An 18-year-old female presented with an abnormal shadow of a 22-mm nodule in the left anterior segment of the upper lung lobe (S3) on chest X-ray and computed tomography (CT). Thoracoscopic partial lobectomy was performed, when a frozen section suggested spindle cell sarcoma of extrapulmonary origin, including malignant fibrous histiocytoma (MFH). ⋯ Primary pulmonary MFH is usually treated by total resection, however, in the current case we performed a partial lobectomy with clear margins and a watchful follow-up without any additional aggressive treatment. No relapse has been observed for 3 years after the surgery.
