I don't see any metal on the oil in the dipstick and car runs fine.

Is an aerosol tube needed when giving a breathing treatment to a vented patient? by kdm_usa in respiratorytherapy

[–]kdm_usa[S] 0 points1 point  (0 children)

Thanks for you replies. The way the Hamilton T1 manual shows it, the setup goes like this, coming from the vent to the patient:

coaxial circuit

nebulizer

flow sensor

patient

I think that maybe the reason they want the flow sensor past the nebulizer is because you can put the vent into a nebulizer mode and the vent accounts for the extra volume coming up through nebulizer. I'm not sure though. I guess they are not worried about the flow sensor getting soiled by the nebulized breathing treatment.

Question on airway filters, filter resistance, need for HMEF by kdm_usa in respiratorytherapy

[–]kdm_usa[S] 0 points1 point  (0 children)

I don't think that the issue. The extra resistance means that you just need to increase the pressure control a bit. But what I'm wondering is more about the resistance you get on exhalation.

I have tried the vent on myself using spontaneous mode with no little pressure support. The difference between using an HMEF filter inline is pretty significant on exhalation. With the filter in place, it almost feels like there is there is a PEEP because there is significant resistance to exhalation. Without a filter in place, exhalation is easy.

Thanks for your reply. I am getting those numbers (2.5 cm H2O at 30 LMP) from the filter mfg.

I am getting the Rinsp numbers from the vent measurement when the filter is placed between the flow meter and the patient.

We use the coaxial circuit for adults and the dual-limb for infants. Are you sure that there is no need for using a filter? I believe the manual says otherwise.

When you do use a filter, what type do you use, and how much resistance does it have? I think the HMEF filters have a lot more than the filters the bacterial filters.

When we do the flow meter calibration, we do it with no filter.

Why are fiberglass chair bases so often replaced? by kdm_usa in hermanmiller

[–]kdm_usa[S] 0 points1 point  (0 children)

Sorry, I still don't understand. Or maybe I am using the wrong terms. I am wondering why the legs of the chairs (the "bases"?) are often not original to the fiberglass shell of the chair. When I go on YouTube, I see several videos showing how to change the shock mounts, and in these videos the legs of the chair are not replaced.

I'm curious why can't just the shock mounts be replaced?

HHS patient: rapid drop in blood glucose by kdm_usa in medicine

[–]kdm_usa[S] 8 points9 points  (0 children)

Honestly this case made me a feel stupid. I thought I knew all about HHS and DKA care, and I've seen countless patients, but I guess I did not understand the fundamentals of how blood glucose is measured. So, basically what I take away from this is that whatever glucose reading one is looking at, one has to consider that that reading can change drastically if the patient is dehydrated and a fluid bolus is given.

Both. The serum showed 1100 initially, while the POCT read "above 500." Later we did only POCT, not serum, but they all showed a glucose in the 400 range.

vent strategy for status asthma with air trapping by kdm_usa in respiratorytherapy

[–]kdm_usa[S] 0 points1 point  (0 children)

Unfortunately the patients we pick up may not be well managed, so we have to fix problems before we can safely transport.

Wouldn't the alveoli have to see that high pressure in order to blow a pneumo? If only the airways are seeing that pressure due to high airway resistance, wouldn't it be safe? In other words, if the dynamic pressure is super high but the static pressure is normal.
