Upper and lower respiratory tract infections. Nursing intervention.

Proper nursing intervention can assist in the reduction of nosocomial respiratory tract infections. Maintaining the integrity of the patient's respiratory defense mechanisms and/or augmenting those that are impaired helps to control endogenous factors that can contribute to infection. Nursing implications in controlling endogenous factors include mobilization of secretions, prevention of aspiration, and reduction of oral resident microorganisms. Strict aseptic technique in caring for artificial airways and respiratory assistance equipment is essential. Advocacy of a patient's right to protection from harm should be exercised if breaks in proper technique by others are observed. The care that nurses provide is relevant to infection control.
