Respiratory and heart rate monitoring dataset from aeration study

A study was conducted to collect respiratory pressure and flow data for model-
based assessment, alongside electrical impedance tomography (EIT) aeration,
electrocardiogram (ECG), and heart-rate belt (HRB) data. A 20 subjects set was
selected with no known significant respiratory abnormalities, under University
of Canterbury Human Research Ethics Committee (HREC) consent (HREC 2023/30/LR-
PS). Subject demographic data was collected using a combination of
measurements and a self-reported questionnaire. Subject demographic
information to ascertain: sex; height; weight; age; any history of asthma,
smoking, or vaping; and approximate thoracic cage and breast tissue volumes.
The trial was setup with subjects breathing through the pressure and flowmeter
using a full-face mask and filter. Inspiratory and expiratory flow were
separated using one-way valves for measurement purposes and both ports were
rapidly occluded every 200ms to generate passive mechanics assessment
intervals. A continuous positive airway pressure (CPAP) machine was used to
provide positive airway pressure (PEEP) in series with the inspiratory port.
Three trials were conducted per subject. Two of which, involved increasing
PEEP (0, 4, and 8 cmH2O), and in one of which subjects were asked to perform
two 10s breath holds at each level. The third was a recording of three forced
expiratory manoeuvres (FEM). These tests were conducted to provide an initial
comparison of current respiratory techniques to model-based methods, which
aims to inform the design of future clinical testing on subjects with known
respiratory abnormalities.
