A patient with a past medical history of COPD was placed on a ventilator after upper abdominal surgery for a serious wound infection. Although the patient was medically stable, a tracheostomy was performed 2 weeks later because the patient was unable to be weaned from the ventilator. The patient is on VC-CMV, rate = 12, VT = 700 mL, FIO2 = 40%, PEEP = 5 cm H2O, with an HME. The respiratory therapist notes that the patient is assisting at a rate of 18 and has bilaterally decreased breath sounds in the bases. The respiratory therapist suctions a moderate amount of very thick, tenacious yellow sputum from the tracheostomy tube. What action should the respiratory therapist take?
