Noninvasive Positive Pressure Ventilation (NIPPV)-Associated Expanding Hiatal Hernia Causing Pulmonary Tamponade: A Case Report on Unusual Complication of NIPPV.

Numerous diseases related to gastric distension have been found and shown to be linked with noninvasive positive pressure ventilation (NIPPV). We describe the case of a 93-year-old female who came with progressively worsening shortness of breath that initially responded to NIPPV but subsequently deteriorated. Imaging revealed gaseous distension of a preexisting hiatal hernia with air-fluid levels and compressive effects on the left lower lobe of the lung.

COVID-19-Associated Spontaneous Pneumomediastinum and Pneumopericardium: Review of Case Series.

Coronavirus disease 2019 (COVID-19) and its spectrum of respiratory illnesses ranging from mild to severe and critically ill have been well established. Spontaneous pneumomediastinum and pneumopericardium (PP) appear to be less reported entities and have been found to be reported complications in COVID-19 infection. Pneumomediastinum (PM) and PP are characterized by the presence of air in the mediastinal and pericardial cavity, respectively.
