Randomized Controlled Trial Clinical TrialAcute effects of CPAP and BiPAP breathing on pulmonary haemodynamics in patients with obstructive sleep apnoea.
Continuous positive airway pressure (CPAP) breathing increases alveolar and intrathoracic pressures, hampering venous return and pulmonary capillary flow. Bilevel positive airway pressure (BiPAP) breathing assuring lower expiratory pressure should impede less the pulmonary circulation. We aimed to compare the effects of CPAP and BiPAP breathing on pulmonary haemodynamics in patients with obstructive sleep apnoea (OSA). ⋯ BiPAP breathing had no effect on intravascular and transmural pressures, Q' and pulmonary vascular resistance. We conclude that continuous positive airway pressure breathing increases pulmonary intravascular but not transmural, true, pressure. Bilevel positive airway pressure breathing does not affect central pulmonary haemodynamics.

Case ReportsSubcutaneous emphysema of the chest wall: a case with unusual presentation.
Subcutaneous emphysema (SE) is the presence of air or other gas in the subcutaneous tissue and is generally associated with pneumothorax and/or pneumomediastinum. We describe an unusual presentation of SE of the chest wall without radiological evidence of pneumothorax or pneumomediastinum, which aetiopathogenesis remains open to several hypotheses in spite of an accurate clinical study.
