Simulated Obstructive Disease Respiratory Pressure and Flow

The dataset presented is from 20 healthy adults at the University of
Canterbury, where the tests were approved by its Human Research Ethics
Committee (HREC) ethics. Data was collected using a modular device simulating
the effects of Chronic Obstructive Pulmonary Disease (COPD) in healthy people,
and in particular, the gas trapping due to airway collapse in expiration.
Pressure and flow data were recorded in this trial using a y-split venturi
with the device attached to the exhalatory outlet by the mouth. Data was
collected using continuous positive airway pressure (CPAP) ventilation at
positive end-expiratory pressure (PEEP) settings of 4 and 8 cmH20, and without
the CPAP at zero end-expiratory pressure (ZEEP). The recording time for each
test was 45 seconds with time in between each test to allow subjects to
recover. Each subject filled out a de-identified demographic questionnaire to
gather background information, including age, height, sex, and history of
smoking, vaping, or asthma. The data collected is intended to be used as a
preliminary validation method of respiratory computational models, where the
device use avoids the need to test unhealthy people or use invasive methods.
