Anyone know how to set a Bi-PAP Puritan Bennett Knight STAR 330?

Question

I need to know how to set the pressures any help would be greatly appreciated!!

Answer 1

I guess no one is answering this question. I haven't used this particular machine, but you can set the Inspiratory Pressure with the up and down arrows... navigating the menu to find IPAP for inspiratory pressure, and EPAP for end-expiratory pressure (which is synonymous with CPAP and PEEP). The range is 2-30 cmH2O of pressure. Typical "minimum" settings would be EPAP of 5 cmH2O. Typical for IPAP would be about 10-15 cmH2O... as IPAP minus EPAP equals the level of pressure support (the amount of push given when the user triggers an inspiration from the machine).

[UPDATE: According to the manual, the factory default is IPAP 5 cmH2O and EPAP of 3 cmH2O]

[UPDATE]: To be able to change parameters on the machine, you need to switch the machine to "Clinician Mode". You can do this by following directions in section 2.4 of the Clinician Manual by pressing and holding the MODE and UP-arrow button simultaneously for 2 seconds after the power-on self test. I'm guessing this is the ANSWER you you were looking for. Follow instructions on section 2.4.2 to adjust the parameters.

It took a while to find the manual, as this product is discontinued.

You can go to http://www.puritanbennett.com/serv/Manuals.aspx and download the manual in PDF format. They have the user manual, the clinician's manual, and also the service manual.

When you navigate to the page use the drop-down menu to find "CPAP/Bi-Level Devices"

Then find "KnightStar 330 Bi-Level Ventilator" under the second device drop-down.

There you should find the manuals.

The KnightStar 330 ST has three ventilation modes. [UPDATE: According to the manual, the modes are CPAP, I/E, and A/C. The terms CPAP, EPAP, and PEEP all mean the same thing... which is the level of end-expiratory pressure. I/E is the mode with a minimum CPAP level along with the pressure-supported IPAP breaths, which are patient triggered. A/C is the timed mode with just machine triggering on top of the I/E mode]

Essentially, you have to tweak the settings of IPAP and EPAP to the level of user comfort.

Hope that answers some of your questions. I'd write in more detail, but the manual should help you navigate the menu settings.

Good luck.
