Pressure, flow, and dynamic thoraco-abdominal circumferences data for adults breathing under CPAP therapy

A respiratory pressure, flow, and dynamic circumference (chest and abdominal)
dataset was collected from 30 healthy adults at the University of Canterbury
under Human Research Ethics Committee (HREC) ethics. Pressure and flow data
was collected using a bi-directional Venturi, with data combined in post-
collection processing. Dynamic circumferences were measured using inelastic
band tape measures attached to rotary encoders capturing expansion and
contraction. Data was collected at zero end-expiratory pressure (ZEEP) and
with continuous positive airway pressure (CPAP) ventilation, at positive end-
expiratory pressure (PEEP) settings of 4 and 8 cmH2O. Data was also collected
over three breath types, in which subjects were instructed to breathe
normally, to pant as fast as possible, and to breathe as deeply as possible.
Recording times were set to 65 seconds for normal and deep breathing, and 35
seconds for panting trials. Subjects self-determined rest time between trials.
A questionnaire was used to collect relevant demographic data (sex, height,
age, weight, and history of smoking or asthma). The dataset was collected to
inform and validate model-based respiratory monitoring systems, with the
ultimate goal of shifting respiratory testing from specialist clinical
settings to primary care and home settings
