Respiratory

Respiratory parameters such as airflow and nasal pressure are significant when undertaking sleep studies in regards to detecting respiratory disturbances.

ADInstruments’ flexible and easily customized systems are designed to be simple to setup and use, minimizing interference with your sleep study subjects to ensure accurate recording and results of their respiratory activity.

We can help you match Labchart and PowerLab with a comprehensive range of solutions for recording high quality respiratory signals, giving you the power choose robust combinations that best meet your requirements. Our software is algorithm agnostic giving you the ability to easily customize macros suited for your preferred sleep scoring methodology.

Record and analysis a range of respiratory and pulmonary pressures including

Airway resistance (pressure difference developed per unit flow into or out of the lungs)
Airway conductance (flow generated per unit of pressure drop across the airways)
Compliance (volume change per unit of pressure change)
As well as Maximal Inspiratory Pressure (MIP) (greatest subatmospheric pressure developed during inspiration against an occluded airway)
And Maximal Expiratory Pressure (MEP) (highest pressure that can be developed during a forceful expiratory effort against an occluded airway)

The simultaneous measurement of respiratory gas concentrations and airflow with our metabolic systems permits the calculation of the following metabolic parameters.

VO₂, the rate of oxygen consumptions (L/min)
VCO₂, the rate of carbon dioxide production (L/min)
RER, respiratory exchange ratio (VCO₂/VO₂)
VE, the expired minute ventilation (L/min)
