Endotracheal Tube and Tracheostomy Tube Cuff Care CORRECT ANSWER ... Which statement regarding endotracheal tube and tracheostomy tube cuffs is accurate? CORRECT ANSWER Cuff pressure should be maintained between 27 and 41 cm H2O to decrease the risk of mucosal damage and establish an effective seal. While injecting air into the cuff, the nurse notes that there is no audible leak on inhalation during ventilation with the MRB, and the patient is unable to speak. Which intervention is the most appropriate? CORRECT ANSWER Connect the patient to the ventilator to implement mechanical ventilation because cuff inflation is appropriate.
