Respiratory bi-directional pressure and flow data collection device with thoracic and abdominal circumferential monitoring

Pulmonary function testing dataset of pressure and flow, dynamic circumference, heart rate, and aeration monitoring

“…A custom pressure and flow meter was used to non-invasively monitor airway opening pressure and flow [1] . Expiratory and inspiratory pathways are split using one way valves, which allows a shutter to rapidly occlude the expiratory pathway for the identification of passive lung mechanics [1] . A filter connected to a face mask was connected in series between the patient and this pressure and flow meter for each test [1] .…”

“…Expiratory and inspiratory pathways are split using one way valves, which allows a shutter to rapidly occlude the expiratory pathway for the identification of passive lung mechanics [1] . A filter connected to a face mask was connected in series between the patient and this pressure and flow meter for each test [1] . In tests 1 & 2 a CPAP device (SleepStyle SPSCAA, Fisher and Paykel Healthcare, East Tamaki, Auckland, NZ) was connected to the inspiratory port of the pressure and flow meter to provide set positive end expiratory pressures (PEEPs).…”

“… Code files are included in .mat format. Data collection A custom pressure and flow meter [1] , ECG [2] , [3] , [4] , PPG [5 , 6] , Dräeger PulmoVista 500 EIT, and Garmin HRM Dual heartrate belt were used to collect data in this trial. Data were recording over three tests for 20 subjects, evenly split by sex [7] .…”

“…Data were recording over three tests for 20 subjects, evenly split by sex [7] . In all trials the subjects wore a full-face mask and filter connected in series with the pressure and flow meter [1] . Test 1 incremented PEEP settings using a Fisher and Paykel Healthcare SleepStyle SPSCAA CPAP device connected to the inspiratory pressure and flow meter inlet.…”

Obstructive respiratory disease simulation device

“…The COPD simulation device presented is designed to avoid having to test unhealthy and/or fragile subjects, while minimising the need for invasive or equipment-specific tests, which usually come at a far higher time and economic cost. It is designed to be used in conjunction with an open-access venturi-based flow sensor [1] , [4] , to measure pressure, flow, and breath tidal volume, which can then be used to replicate COPD pressure-flow loops from healthy subjects with much lower cost and risk.…”
