Trial Outcomes & Findings for Non-invasive Tidal Volume Monitoring Using the Linshom Respiratory Monitoring Device (NCT NCT03279458)

NCT ID: NCT03279458

Last Updated: 2018-07-05

Results Overview

Tidal volume measured by CPAP mask with Lishom respiratory monitoring device. Tidal volume determined from the ventilator will be compared to tidal volume measured by Linshom (calculated indirectly by temperature changes by computer algorithm)

Measure
Linshom Respiratory Monitoring Device
Volunteers will breathe through a continuous positive airway pressure (CPAP) face mask fitted with the Linshom device. The volunteers will be instructed to breathe normal through the CPAP mask on room air. The excursions of the thermistor tracings (from valley to peak) will be recorded by the Linshom device and displayed continuously on a laptop monitor in a waveform. The tidal volume will also be measured by the ventilator and the data downloaded in a Compact Flash card.

PRIMARY outcome

Timeframe: 5 minutes

Population: Thirty participants successfully completed the experiment, which involved breathing through a CPAP mask in order to have the Linshom device record excursions of the thermistor tracings while the ventilator concurrently measured tidal volume.
