Getting waveform data from the Puritan Bennett 840
Hi everyone,
Sorry to keep asking questions, but this one has actually bugged us for a while now. Do you know how to make the Puritan Bennett 840 ventilator output waveform data?
We have tried all ports but all we get is the miscf message with numeric data only. We can't see any options on the ventilator itself either. As far as I understand from the code, the PB demo is also only set up to ask for numeric data.
Any insight you might have will be appreciated.
Thanks!

This is an interesting question that has two possible answers for you:
If you are using the OpenICE supervisor GUI, and you click create a device adapter, select Puritan Bennett 840, the GUI only presents you with one serial port dropdown. It should present you with two selectors - one for waveforms, one for everything else. This is an error and I will put it in the queue to fix - thank you for bringing it to our attention. In the meantime, try starting the PB840 device adapter from the command line with options. On Ubuntu, the command from the OpenICE directory would be:
The PB840 is an interesting device with respect to the data export interfaces. The PB840 has several versions available, some with the capability to export waveforms some without. The easiest way to tell is to look at the back of the monitor and count the serial ports. Newer PB840s will have three ports - see the attached photo: PB840-serial-ports.JPG. Port 3 is the "high-speed" waveform port. To configure this port for use on PB840 GUI, on the lower screen touch "other screens" > "communication setup" > then touch the top box with the 3 and set it to waveforms - see the attached photo: PB840-comm-setup.JPG.
Hope this helps. Let me know if this works for now,
Jeff
Thanks for the answer. We'll try this in a couple of days and will let you know how it goes. We do have the same machine with the three ports. We hadn't seen the waveform option, though. Perhaps we didn't look at port 3.

OpenICE v0.6.1 now features two GUI inputs for serial interfaces for the PB840 device-adapter. The new version can be downloaded from http://mdpnp.sourceforge.net/. Thank you for your input on this issue.
Thanks,

Sorry but we have not used either or the Servo-i or LTV ventilators in the lab. My best advice is to contact your sales representative and ask for the 'data export specification' or 'programmer's guide'. The manufacturer should be able to provide you with the documentation needed to communicate with the device.
