Clinical Implications of Assisted Peak Cough Flow Measured With an External Glottic Control Device for Tracheostomy Decannulation in Patients With Neuromuscular Diseases and Cervical Spinal Cord Injuries: A Pilot Study

The external glottic control device substituting for innate glottic function is beneficial for determining tracheostomy decannulation. It provides an objective and accurate APCF. It is particularly helpful for patients whose APCF is ≥160L/min while using the device, even if APCF is <160L/min without this device.
