Setup and Pre-Use Preparations

Making Parameter Changes

3.5
Most parameters are changed with a simple touch/adjust/accept method:
Activate the control by touching it (the button will appear highlighted).
1.
Use the Up/down buttons to adjust the setting.
2.
Press the Accept button to accept the change. To reject the change and return to the previous setting,
3.
press the Cancel button.
Several adjustments can be made before accepting the changes. When satisfied with the chang-
es, accept them all by pressing the Accept button once. In the case of a mode or breath type
change, select the Main screen for view, change the mode or breath type, and then adjust all
visible parameters prior to pressing the Accept button.

Note:
If a parameter is touched and adjusted but Accept is not pressed within 20 seconds of the last button
touched, the parameter will revert to the original setting.

Attaching a Patient Circuit

3.6
Always use a clean and dry patient circuit.
Always use a proximal inline filter (part number HT6004701 or equivalent) at the prox line connec-
tor to protect the internal transducers from moisture or other contaminants.
Always use a bacteria filter (part number FLT3302P or equivalent) on the gas output connector.
Always orient the exhalation valve for the correct flow orientation. Valves used in a single-limb
circuit have arrows that point toward the patient, and valves that are used in J-style or two-limb
circuits have arrows that point away from the patient.
When using the on-airway flow sensor, orient it so that the blue tubing is toward the patient.
The Newport HT70 Ventilator will perform to specification when Covidien-recommended breath-
ing circuits and exhalation valves are used. Covidien cannot guarantee the safe use of breathing
circuits or exhalation valves that are not recommended.

With a Third-Party Humidifier

3.6.1

use. Refer to Figure 3-6. , Figure 3-7. , Figure 3-8. , and Figure 3-9. during the following set-up pro-
cedure.
