I just had my 3 monthly PFT today to see whether there was any change in my DLCO levels. The technician told me that my numbers were the same as my last PFT 3 months ago. When I got home I got the hospital to fax me through the results, I then noticed that on the top of the report, they had put my old weight down instead of the weight I was when weighed today. I am 3 kilos heavier than 3 months ago, does anyone think it would make much of a change in my DLCO numbers?

Many thanks
Celia

I think it could make a difference. I'm always weighed in the room just before my PFT.
You may want to talk briefly with the Doctor and let him know and ask him directly if it makes a difference.

Hi Celia,

That's terrific that your DLCO is stable, at least for now! 3 kilos is about 2 pounds. Most people can vary that much within a day, so I don't think it would be worth mentioning or inquiring about with them. Of course, I'm not a doctor and have no medical training at all...

But this brings to mind my very first PFT, when they took my weight in pounds but listed it as kilos, then converted it to pounds. So let's say someone weighs 150 pounds. 150 kilos equals 331 pounds. And I'm very short.

The analysis was to the effect of saying, OF COURSE this person has difficulty breathing and restrictive lung function! What do you expect from someone who is so massively obese?

The words "massively obese" caught my eye. I'd go along with obese, very obese, hugely obese, but I draw the line at "massively". :o But my doctor had read the results without even blinking an eye and told me that considering my weight, my lung function was as good as could be expected.

This is another lesson for all of us as to why it is important to request and read our medical records from time to time. I might add this could go for dental records as well -- for my old dental clinic had me listed as having had a heart transplant; which I've never even dreamed of! Then when I reported this, they refused to erase it from my records. Even when they enter something wrongly, it still stays in the chart forever.

Boy, did I ever digress. Sorry about that, Celia. But back to the point, they hardly noticed the difference even with my massive obesity :o so my impression is that they are more likely to care about general ballparks, than a few pounds here or there.

Ah, Shelley. I wish it were true. But a kilo is 2.2lbs. Your numbers in the example are correct, though.
Warm wishes,

Hi Jefa,

Oh whoops! :blink: See I'm not a doctor, not a mathematician...why I'm more "nots" than anything. But at least I'm good for some laughs. And if y'all ever get hungry, you'll always find plenty of egg --- on my face. :lol:

Thanks Shelley, you are right, I called the hospital where I had the pFT done and they altered my weight and faxed me through a copy of the results. Everything is basically the same, the 3 kilos hardly made a difference to the percentages.

Take care
Celia :)
