If anyone has any experience with the HT50, I would love to hear your opinion or comment on this ventilator.

Thanks,

we use HT50 in almost all of our patients requiring vent outside of ICU. HT50 requires no compressed air and in absence of O2 blender, bleed in O2 can do. We also use HT50 for adult patients requiring medical escort going to places in USA, UK,etc. Ventilator is very handy, with wide range of mode selection. Personally I am confident with this machine using above proceedures on VOLUME VENTILATION mode only....

That is my problem, we use it with pressure control on our Peds. Can you tell me reasons why you do not use pressure control with this vent. Then maybe I can convince them not to use this vent for pressure control.

In the province I work in all chronic ventilator pediatric patients now receive either a Newport HT50 or a LTV 1000. We have used pressure control in this pediatric population on the HT50 without any problems. The Newport is a nice easy to use ventilator that has a good battery life and internal PEEP unlike the LTV which has a fairly short internal battery life and externally set PEEP. The Newport is a tough vent too, it can take a bit of abuse (not that we normally abuse our ventilators), it was designed by the Israeli military for transporting critically ill patients.

Let me know if you have any specific questions about the ventilator.

I am confused about the peep compensation. It is peep compensated, therefore when I set a PC of 15 with a peep of 5, I should see PIPs of at least 20. However, I only get PIPs of 16-17.

With the Newport, set level of PC is above ambient (atmospheric) pressure, it is not a PC level above PEEP. So, your PC essentially equals your PIP.

Now with the PS (pressure support) level it is different, the PS level is above PEEP.

I know this seems strange but that is the way its is. If you ask Newport they will give you some long winded answer of why this is.

It would be nice if all the ventilator companies would just do this the same already.

Hope that clears it up for you.

This should be fun since I just went through explaining this at work. I read that PC and PS were peep compensated on this vent, so they ended up changing a patients PC setting. Thank you so much. I will make sure to clarify this at work.

Thank you so much. I finally found it in the manual and you are correct. PS is peep compensated and PC is not. I wish the manual would have stated that more clearly.

Thanks again!

At one hospital I worked at we had both Servo 300A and Drager Evita's. The Servo vent had PC defined as ABOVE PEEP (Peep 10 and PC 20 meant PIP of 30). Whereas the Drager had PC as a constant value (PC 20 with Peep of 10 meant PIP of 20).

Every so often (for often really bizzare or stupid reasons) there would be a vent change from one to the other. So you can imagine the results as the default settings were then just matched to the orders---"how come the VT went up" (Or down).

I guess there are two approaches. If one is using PC and wants to by inference limit the Pressure then Pressure Constant PC makes sense. But if one wants to use PC such that one has VT distension constant then having it Peep compensated makes sense. IMO one can work with either approach and with a modicum of intelligence achieve either or both goals. It's when one has set orders and then changes set vents that a bit of chaos reigns.

If anyone knows of other vents that are not peep compensated, whether its just the PS or the PC or both, I would like to know about them.
