Brief summary
Computational models of lung have been developed to assess lung mechanics. Recently these methods have been developed to be identifiable in spontaneous normal breathing, where historical quantification of muscular effort and technological capacity limited these assessment methods. Bench testing these methods have been made using a mechanical test lung and healthy subjects have been tested at the low-risk clinical unit at the University of Canterbury. This study would be a pilot feasibility test in a clinical population to establish clinical efficacy to justify further testing and technology/methodology improvements.
Interventions
A new resting breathing pressure and flow measurement device with be tested (pressure and flow meter with a rapid expiratory occlusion (REO) valve. Where, computational models will be used to assess lung function parameters from the new device following the study. The subject will be instructed to breathe (at rest) through the device using the mouthpiece (similar to spirometry) by a researcher for 3-5 1 min recordings. This test will occur in the pulmonary physiology lab at Christchurch hospita
