Respiratory

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.

In conjunction with our complete systems shown below, any device with an analog output (+/- 10V) can be connected to a PowerLab data acquisition system for synchronization of event in LabChart. So you have even more flexibility and can integrate all your data streams in one place.

All of our hardware recommended for human use is backed by the appropriate safety certification standards. More information on safety standards.

Signals Supported

Pressure
+

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) 
Respiratory Flow
+

Measure Peak expiratory flow (PEF) as maximum flow rate attained during FVC maneuver, or peak inspiratory flow (PIF) as peak flow rate at inhalation. Graph flow-volume to indicate obstruction and/or restriction present in airway abnormalities.

Respiratory Gas Analysis
+

 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) 
Respiratory Rate
+

Measure breathing trace / breathing rate through changes in band circumference are used to characterize breathing patterns (inhalation, exhalation and breathing strength). 

SpO2
+

Record pulse and blood oxygen saturation (SpO2) in relation to other signals like ECG, spirometry or blood pressure. 

Temperature
+

Nasal temperature can be used as an indicator of respiration.

Volume
+

Measure Forced Vital Capacity (FVC),  Forced Expiratory Volume (FEVT) as measures of expired gas volumes.

RER higher than expected?

RER is calculated by dividing VCO2 by VO2, therefore if the VCO2 is higher than expected but the VO2 is normal, this would explain the high RER. Alternatively, if the VCO2 is normal, but the VO2 seems low, this would also explain the high RER. In either case, the raw CO2 and O2 values should be assessed by recording known concentrations of each to make sure these are calibrated correctly. If the CO2 and O2 values are not contributing to the high RER, the flow calibration should be checked. Other factors that might cause a high RER are subject panting/breathing uncomfortable once the face mask is attached creating a higher than normal CO2 output. Another common problem can be air leaks, either from around the face mask which must be completely air tight, or within the breathing circuit.
