•• | CV |
•• | AC |
•• | SIMV |
Circuit Type
There are three circuit types you can select:
•• | Passive |
•• | Active PAP |
•• | Active Flow |
The Passive circuit type uses the Whisper Swivel II passive exhalation device. The Active PAP circuit type uses an active exhalation device with a proximal air pressure sensing connection. The Active Flow circuit type uses an active exhalation device with a proximal flow sensor.
When using the Passive circuit, the ventilator displays estimated patient pressures based on the resistance of the standard patient circuit (Whisper Swivel II with 1.8 meter tubing). Adding accessories to the patient circuit (humidifier, water trap, etc.) may cause an increase in circuit resistance and cause the device to display slightly higher pressures than what is actually delivered to the patient.
With the Active PAP or Active Flow circuit type selected, patient pressure is measured directly and is not affected by any change in circuit resistance.
Note: See Chapter 3 for detailed information about each therapy mode.
Note: Refer to the chart in Chapter 3 to easily review all of the settings available in each therapy mode.
Note: This chapter describes how to enable all of the device settings, including device alarms. For detailed information about each alarm, please refer to Chapter 6.
Note: To change the circuit type, you must be in the Setup screen with the airflow turned off. See the Full Menu Access Mode section for more information.
Note: When the Circuit Type setting is set to Passive Circuit, all Ramp Start Pressure settings in all modes will maintain the minimum range.
Note: When the Circuit Type setting is set to Active PAP or Active Flow, the Flex and AVAPS features are unavailable.
