Modified Technique for Assessing External Respiration Function in Chronic Tracheostomy Patients

Abstract

The function of external respiration (quiet breathing and forced maneuver) was studied in two groups of subjects: 18–24-year-olds (n = 48) and 50–60-year-olds (n = 36). Their parameters were recorded using the Spiro-Spectrum device (Neurosoft). A modified technique was tested taking into account the functionality of respiratory maneuvers in people with a permanent tracheostomy tube. Regression equations were derived to assess the external respiration function in tracheostomy patients and compare their parameters with normal values.
