An infant with hypoplastic left heart syndrome, excessive pulmonary blood flow, and tachypnea was placed on subatmospheric oxygen (supplemental nitrogen) to increase pulmonary vascular resistance and decrease pulmonary blood flow. His cardiorespiratory status stabilized without mechanical ventilation, but 2 weeks later he developed spontaneous subcutaneous emphysema. The emphysema worsened over approximately 1 month. During this time his left-to-right shunt gradually decreased, and he was weaned to room air. Even without the use of supplemental oxygen the emphysema resolved without complication, and the patient underwent successful orthotopic heart transplantation at 65 days of age.
一名患有左心发育不全综合征、肺血流量过多和呼吸急促的婴儿被置于低于大气压的氧气环境（补充氮气）中，以增加肺血管阻力并减少肺血流量。他的心肺状况在没有机械通气的情况下稳定下来，但2周后出现了自发性皮下气肿。气肿在大约1个月内逐渐加重。在此期间，他的左向右分流逐渐减少，并且逐渐停用氧气直至使用室内空气。即使没有使用补充氧气，气肿也自行消退且无并发症，该患者在65日龄时成功接受了原位心脏移植。
