Assessment of Cough Strength in Patients With Tracheostomies

NCT02566512 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 20

Summary

The investigators propose to assess cough strength in patients undergoing spontaneous breathing trials in the Intermediate Intensive Care Unit (IICU) and compare their cough strength under two conditions,

1. Tracheostomy cuff inflated: cough strength will be measured with the tracheostomy cuff inflated and the patient coughing through the tracheostomy tube.
2. Tracheostomy cuff deflated: cough strength will be measured with the tracheostomy cuff deflated and the patient coughing around the tracheostomy tube, through their mouth..

The investigators hypothesize that patients will have a stronger cough when they can use their vocal cords.

Conditions

  • Mechanical Ventilator Weaning

Interventions

OTHER

Tracheostomy cuff inflation.

With the tracheostomy cuff inflated, the peak expiratory flow meter will be attached directly to the tracheostomy tube. The patient will be instructed to take as big a breath as they can and then forcefully cough. This will be repeated four times.

OTHER

Tracheostomy cuff deflation

With the tracheostomy cuff deflated, a one-way valve will be attached to the tracheostomy tube. The patient will use a mouthpiece to connect to the peak expiratory flow meter. The patient will be instructed to take as big a breath as they can and then forcefully cough. This will be repeated four times
