Blood donation & DCS

I would like to know if a diver is more inclined to get DCS if he donates
blood 12 hours prior to dives that involve some minor (10-15 min) mandatory
deco stops and dove with conservative tables. Dive and deco done on 30%.
Plenty of fluids taken.

Not even getting into deco, I don't think I'd want to dive at all 12 hours
after giving blood. I'd way several days for your body to build the red
cells back up.

And fluid.

Several days is a lot, my guess is about two.

I'm always told to not lift heavy objects for 24 hours and to avoid
strenuous exercise for at least 12.

There has been no correlation between blood donation and DCI.

How long will it take to replenish my blood?
Blood volume or plasma is replaced within 24 hours. Red cells need about 4
to 8 weeks for complete replacement.

How will I feel after the donation?
Most people feel great! Donors who know what to expect and have eaten
regular meals before donating are usually fine. After donating, drink extra
fluids for the next 24 hours and avoid strenuous exercise.

How soon after donating can I resume exercising?
Heavy muscular or strenuous activity such as lifting or pushing heavy
objects should be avoided for 4 to 5 hours after giving blood, as this may
cause bleeding from the needle site. Strenuous exercise should be postponed
until the day after your donation.

I'm conservative. :) Dive saturday and sunday, give blood on a Tueday and
head back to sea on Saturday.

BTW an FAQ I found said plasma is replaced in 24 hours and red blood cells
take 4-8 weeks. I guess how long to wait past 24 hours is going to be
determined by someones initial cardio fitness level.

Well, yeah. "plasma" is just the liquid, cell free part of the blood.
It's almost entirely water with ions and dissolved matter. Your body
notices the lost blood volume and replaces it very quickly... the actual
blood cells you gave up take a while for your body to actually manufacture.

I can't see how any of it would affect your risk of DCS, though. It's
not like red and white blood cells bring nitrogen into your tissues..
that stuff is dissolved in the water of your body.

The lack of plasma is equivilent to being dehydrated, which definately
increases your chances of DCS (plasma is the transport vehicle for
nitrogen). Chris' cite of 24 hours to replace lost plasma is probably a
good guideline.

One could also call DAN and ask, of course
