Developments on Split Vent Theories

:tiphat:I talked to a rep for Dr. Bird.:D He is Giles Wilson. He says the splitter question was very interesting and would ask the dr if it is feasable.. and that they are working very hard on the H1N1 problem. He mentioned another small devce, that may be helpful also, a small machine for patients to use to prevent moving to a larger full time vent. I told him who I was and what I do, He also asked for this site and thread. He will be contacting me back soon, as he was getting on a plane when I called him. At the least we may find out if a splitter can be used on vents and get a glimpse into other ventilator treatment options in developement. :applause:
 
Re: Developments on Split Vent Theories

Are you talking about one lung ventilation, and/or separate ventilation of each lung? Yes, both are possible. In regard to the "small machine" - I think you may be talking about NIPPV, which is Non-Invasive Positive Pressure Ventilation. I've seen patients avoid intubation with this - but not anyone with ARDS.

If that is indeed what you're referring to, I'll be glad to provide some useful links for you to read further.
 
Re: Developments on Split Vent Theories

Ohhhhh... well that would solve some problems, wouldn't it?

I'm thinking of how that would work... and I don't see how it would, unless the vent settings per patient were identical. It's so much more complicated than putting oxygen through an endotracheal tube. Other issues come to mind: the need to increase O2 temporarily during bathing and/or transient hypoxic episodes, etc... and never mind the physical logistics of two critical care patients sharing one vent. What happens when someone needs to go for diagnostic testing? The vent more often that not travels with the patient to various departments...

Interesting concept though. I'm eager to read more about the possibilities and how the logistics of it all would work.

Forget that. A ventilator system is about managing carefully: volume, pressure (positive and negative), mix (air and O2) and respiratory rythm.
If you have this for two patients, then basically you have two respirators!! :)
 
Re: Developments on Split Vent Theories

Well, that may be the case. When you gotta bunch lined up to die, you may be the first in line with a hose and some duct tape ;)
 
Re: Developments on Split Vent Theories

:tiphat:I just got off the phone with mr Wilson, and he said it WAS possible, He said it would just use more "gas" from the hospital supply. I asked about where could hospitals get the splitter, if they could and where he said he is sending me more info within 48 hrs. So..

:tiphat:This is his email to me recieved today..I never saw the first reply:rolleyes:

This was what I sent a few weeks ago. From testing, it is possible to run two Phasitrons from a single driver but there will be an increase in gas consumption.

Attached is the brochure for the IPV Acute care; we are in the process of updating this and I?ll get you a copy of this. This device is only $2750 so not a huge issue to stockpile but far more expensive than the Vortran device.

Flu (of any sort) and indeed most potential chemical plant releases or other variations on mass casualty result in peripheral airway problems. High Frequency Percussive Ventilation is one of the few modalities that is well proven in this area of airway clearance and lung recruitment (burn patients present the most challenging airways with inhaled smoke and then also possible lung tissue damage).

Gas consumption for a single patient on a single device is about 15 lpm; if one were to split the delivery between two patients (who because of the Phasitron interface could be quite different) would increase gas consumption. We are not sure to what degree, possibly as much as double. We hope to perform some testing on this over the course of the week.

Thanks

I don't see the attachment note, so I will ask for that again :tiphat:
