Setting

Prescription

Parameters

All prescription settings for the KnightStar 330 must be programmed.

Before programming prescription settings, review the physician’s

prescription. Then, proceed as follows:

1. Choose the appropriate interface.

2. Explain the intended therapy to the patient, and offer reassurance

about the procedure.

NOTE:

For correct use, start the KnightStar 330 system before

putting on the mask or interface.

3. Set the mode according to the physician’s prescription (CPAP,

I/E PAP, or A/C). If there is no prescription (such as in a sleep

lab setting), begin with low IPAP pressures in the range of

5 cm H

O to 10 cm H

O, and an EPAP pressure of 3 cm H

NOTE:

When changing from I/E PAP or A/C to CPAP, the CPAP

value will default to the set IPAP value. Press the Set

button and use the ▲ (Up Arrow) or the ▼ (Down Arrow)

button to change the CPAP setting.

4. Set the respiratory rate to the minimum value required to

maintain the patient. Start with a setting of 12 bpm (A/C only).

5. In A/C mode, set the I:E ratio as ordered by the physician.

WARNING:

Some CO

rebreathing is possible during normal operation of

the KnightStar 330, especially at low airway pressures. When

using A/C mode, an I:E ratio of 1:2 or greater is recom-

mended to reduce the possibility of CO

rebreathing.
