“…The small sales market make manufacturing such a device unattractive from a business model. We found one report where a customized flexible adapter was constructed on demand for CPET testing with good success [13] . We describe here the results of creatively using parts on hand, at no cost to the patient, which provided the hermetic, flexible seal we needed to facilitate a cycle ergometry to maximal patient effort.…”

Respiratory Medicine Case Reports

A patient presents with a new bronchogenic carcinoma 5 years after laryngectomy for recurrent laryngeal tumor and 13 years after chemoradiation for concurrent lung cancer with synchronous base-of-tongue tumor. Due to his complex history and perceived limited respiratory reserve, he was felt high risk for the completion pneumonectomy needed for resection of this new tumor. The attending surgeon requested a full cardiopulmonary exercise test for risk assessment prior to surgery. We found that there was no commercially available connector that would allow our CPET equipment to reliably collect respiratory gases from a patient with tracheostomy stoma or tube. We report here a simple coupling devised “in house” that allowed for the performance of an interpretable test leading to a significant change in medical care.
