As costs related to mechanical ventilation increase, clear indicators of patients' readiness to be weaned are needed. Research has not yet yielded a consensus on physiological variables that are consistent correlates of weaning outcomes. Subjective perceptions rarely have been examined for their contribution to successful weaning. ⋯ Multidimensional assessment of both primary and secondary indicators of readiness to be weaned is necessary for timely, efficient weaning from mechanical ventilation. Primary assessments include physiological variables related to gas exchange, hemodynamic status, diaphragmatic expansion, and airway clearance. Secondary assessments include perceptions related to key physiological variables. Additional research is needed to determine the predictive value of physiological variables and perceptions of dyspnea, fatigue, and self-efficacy.

No data have been collected to describe the products, methods, and frequency of oral care needed to reduce dental plaque, oral colonization, and ventilator-associated pneumonia in critically ill patients. ⋯ Despite evidence that they are ineffective for plaque removal, sponge toothettes remain the primary tool for oral care, especially in intubated patients in intensive care units. Nurses report frequent oral care interventions, but few are documented. Education and focus on good oral care strategies are required; nursing research to delineate the best procedure for all patients in intensive care units is needed.

Although low concentrations of inhaled nitric oxide may by therapeutic, both nitric oxide and its oxidation product nitrogen dioxide are potentially toxic. The threshold limits for time-weighted average concentrations of nitric oxide and nitrogen dioxide issued by the American Conference of Governmental Industrial Hygienists are 25 and 3 ppm, respectively. The concentrations of these gases in the breathing space of hospital personnel during administration of nitric oxide to adult patients have not been reported. ⋯ Inhaled nitric oxide therapy at doses up to 20 ppm does not appear to pose a risk of excessive occupational exposure to nitric oxide or nitrogen dioxide to nurses during routine delivery of critical care.

Today's critically ill patients require heightened vigilance and extraordinarily intricate care. As skilled and responsible health professionals, the 403,000 critical care nurses in the United States must acquire the specialized knowledge and skills needed to provide this care and demonstrate their competence to the public, their employers, and their profession. Recognizing that nurses can validate specialty competence through certification, this white paper from the American Association of Critical-Care Nurses and the AACN Certification Corporation puts forth a call to action for all who can influence and will benefit from certified nurses' contribution to patient care.
