Hernia is defined as the protrusion of a totally or partially displaced organ from its normal visceral cavity. Most hernias occur at the level of the abdominal wall, because of a muscular defect. ⋯ We present a 64-year-old patient who developed a spontaneous pulmonary hernia after a severe coughing episode. We describe the clinical features, diagnosis, and successful treatment.

Most portable bi-level positive airway pressure devices are not equipped with air-oxygen blenders for precisely regulating oxygen concentrations, and supplemental oxygen must be added to increase the F(IO2). Very few studies have investigated the factors that affect F(IO2), and their conclusions have been inconsistent. We investigated in vitro noninvasive ventilation (NIV) parameters and their effects on F(IO2), particularly the effect of the oxygen injection site. ⋯ The oxygen injection site had the greatest effect on F(IO2) during NIV.
