简要总结
This research is being done to determine the resistance across stenosis in the airway.
详细描述
There is significant utility in objectively measuring airflow as subjects, undergoing endoscopic laryngeal surgery, commonly have difficulties with airflow secondary to their stenosis. Easier and quicker quantification will tailor diagnosis and treatment. In order to obtain an objective measure of airflow in these participants, we will place a 20-gauge angiocatheter needle into the airway. The catheter will be in situ for a short duration during several spontaneous and non-spontaneous breaths. This will be achieved via the existing tracheostomy stoma or percutaneously via the cricothyroid membrane. This technique is commonly used to access the muscles of the larynx, however, the primary purpose will be to measure airflow in this setting.
