In a prospective study of the complications of cardiac resuscitation, 705 cases were autopsied to identify the cause of death and the pathologic findings attributable to cardiac resuscitation. Thoracic complications were observed in 42.7 percent of the cases. ⋯ Abdominal visceral complications were noted in 30.8 percent of the cases, and pulmonary complications occurred in 13 percent of the resuscitation population. Life-threatening complications, such as heart and great vessel injuries, occurred in less than .5 percent of the cases.

The efficacy of long-term oxygen therapy for hypoxemic COPD patients is well established. However, oxygen is expensive and the portability of home oxygen is limited by the weight and bulk of the oxygen source. As a result, there has been a recent surge of interest in creating oxygen-conserving devices and methods. ⋯ Each has its own set of advantages and disadvantages. By using oxygen conservation methods, the oxygen required to achieve adequate blood oxygenation can be reduced by a factor of 2:1 to 7:1 compared to steady flow. Thus, the cost of oxygen can be substantially reduced while increasing the portability and range of home oxygen therapy.
