Perfusion, hypoperfusion, and ischemia processes: the effect on bodily function.

Adequate perfusion is requisite for normal body function. Should perfusion be disrupted, a cascade of events may result that can lead to disruption of function and potentially cell, tissue, organ, and ultimately organism death. Contrary to logic, reperfusion as a modality of treatment is not without issues in the form of reperfusion injury.

Pressure ulcers and the home health aide: evaluation of an educational program.

In a 6-month period, it was noted that 3 home care patients had developed pressure ulcers although they had been visited by home health aides providing full hygienic care. In an attempt to improve care, an educational program was developed and provided to the home health aides. After implementation of this program, posttest scores improved.

A comparison of the effectiveness of an opioid analgesic and a nonpharmacologic intervention to improve incentive spirometry volumes.

The purpose of this study was to compare the effects of opioid analgesics and relaxation as interventions for incentive spirometry in postcardiovascular surgery patients. With the use of incentive spirometry change scores from pre- to posttreatment, 72 patients received either relaxation, opioid analgesia, or no intervention. Pre- to posttreatment differences in achieved spirometry volumes were significantly different for the 3 groups (F[2, 69] = 7.
