Sexual harassment in the workplace is a prevalent form of impermissible sex discrimination in employment. The high profile of this issue in the media, together with laws prohibiting sexual harassment, have not prevented this problem for working nurses. ⋯ These results suggest that many critical care nurses are harassed and that relatively few hospitals have sexual harassment policies known to employees. They also indicate that sexual harassment training, policies, and procedures are needed to provide a safe, healthy work environment for critical care nurses.

Comparative Study Clinical Trial
The effect of Trendelenburg and modified trendelenburg positions on cardiac output, blood pressure, and oxygenation: a preliminary study.
Although we have insufficient knowledge about the effects of Trendelenburg positions on various hemodynamic parameters, these positions are frequently used to influence cardiac output and blood pressure in critically ill patients. ⋯ This preliminary study does not provide support for Trendelenburg positions as a means to influence hemodynamic parameters such as cardiac output and blood pressure in normovolemic and normotensive patients.

Published reports indicate that survival rates of patients with adult respiratory distress syndrome have not improved dramatically since the first report of the condition in 1967. However, changes in ventilator strategies and improved critical care management may result in better survival rates in patients with well-defined, severe adult respiratory distress syndrome. ⋯ This survival rate exceeds most recently reported rates and thus supports the idea that improvement in treatment of adult respiratory distress syndrome is occurring.

Comparative Study Clinical Trial
Comparison of SVO2, SpO2, and clinical parameters with arterial blood gases during ventilatory weaning after cardiac surgery.
Correlations of mixed venous and arterial oxygen saturation, heart rate, respiratory rate, and mean arterial pressure with arterial blood gas variables were computed for 57 sets of data obtained from 30 postoperative coronary artery bypass graft patients who were being weaned from mechanical ventilation. Arterial oxygen saturation and respiratory rate correlated significantly, although moderately, with blood gases.

Comparative Study Clinical Trial
Comparison of five clinical weaning indices.
Despite extensive data acquired in the area of weaning, clinicians still struggle with the questions of how and when to begin the process. Clinical weaning indices, designed to predict weaning potential, are often difficult to use. They provide an answer at a specific time; extrapolation to the weaning process is rarely possible. No single index has proven to be superior. ⋯ The results of this study suggest that the process of weaning may be enhanced by comprehensive, systematic approaches and that clinical weaning indices like the Burns Weaning Assessment Program might best serve as tools to track trends in progress, keep care planning on target, and prevent unsuccessful weaning trials.
