Question

Quizplus · Accepted Answer

Studies have found that to achieve benefits with rotation therapy,rotation must be aggressive,and the patient must be at least 40 degrees per side,with a total arc of at least 80 degrees for at least 18 hours a day.Kinetic therapy has been shown to decrease the incidence of ventilator-acquired pneumonia,particularly in neurologic and postoperative patients.Complications of the procedure include dislodgment or obstruction of tubes,drains,and lines; hemodynamic instability; and pressure ulcers.Lateral rotation does not replace manual repositioning to prevent pressure ulcers.Continuous lateral rotation therapy (CLRT)has been shown to be of minimal pulmonary benefit for the critically ill patients.
