2.11.1 Overview of
flow paths
2-24
This section looks at three types of flow paths.
• Ventilation paths: How gas flows from the drive source (bag or bellows) to and from
the patient.
• Fresh gas paths: Fresh gas can flow from the machine interface directly to the patient
through the inspiratory check valve, or through the absorber into the expiratory flow,
or directly to an external circuit through the optional auxiliary common gas outlet.
• Scavenged gas paths: APL or Pop-off.
