15Monitoring Airway Flow,
Volume and Pressure
The M1014A Spirometry Module is designed to be used in combination with Philips-branded airway
flow sensors and combined CO2/airway flow sensors. It produces a real time wave for flow, volume and
pressure of respiratory gases together with numerics for analysis of ventilatory mechanics.
The measurement provides:
• Airway flow, airway volume and airway pressure waveform.
•Numerics for:
– respiratory rate
–tidal volume
–minute volume
– PEEP (positive end-expiratory pressure)
– PIP (peak inspiration pressure)
– dynamic compliance
– airway resistance
• Numerics for: (only visible in Spirometry Values Window, no alarming, no trending)
– peak inspiratory flow
– peak expiratory flow
– negative inspiratory pressure
– mean airway pressure
–plateau pressure numeric
– I:E ratio
The measurement also provides pressure-volume loops, flow-volume loops and pressure-flow loops.
Please see the Respiratory Loops chapter for details on loops.
When using combined CO2/Flow sensors you can also perform mainstream capnography with
intubated adult, pediatric and neonatal patients. See the Measuring CO2 chapter for details on the CO2
measurement and the Accessories chapter for a list of compatible accessories.
WARNING Electrical Shock Hazard: Do not open the module. Contact with exposed electrical components may
cause electrical shock. Always turn off and remove power before cleaning the module. Refer servicing
to qualified service personnel.
