Senior Management still donates. She tells me they no long serve tea and
biscuits.
That was to keep you there for a period of 10 minutes or so after giving blood. If someone is going to have a reaction to losing nearly an arm-full it will be in those first few minutes. When I last gave blood decades ago it seemed that the wait was only for those giving blood for the first time or if you had problems on the previous occasion(s). If someone reacted to giving blood the cure was to lie on your back, feet up, for 5 to 10 minutes whilst being observed.
When I had my covid jabs they also recommended sitting in the waiting area (or sitting in your car in the adjoining car park) for 10 minutes before leaving.
It's better to wait in the room. I know when I'm sitting in the
recovery room, I'm watching the other patients for signs. That's
because there isn't always a medical professional in the recovery
room. They roll in and roll out again, and don't stay in the room.
If your throat swells up, you want to alert someone right away.
You can't afford to wait until your airway is cut off, because
there might not be someone there to hit you with an Epipen, or
to fit you with an esophageal airway. Even in a hospital, the
skill at fitting an airway, isn't a given. Histamine reactions
can be so bad, that you can't stop them, but a vaccine is unlikely
to elicit something like that. They ask you questions about your
allergy history, and it would be silly on your part, to not be
honest about these things.
But that's in case you have a histamine reaction to the injection.
For some reason, COVID (if say, made with an egg method), might have
the same egg-reaction concern as the flu shots that are based on eggs.
I think the flu shot was 10 or 15 minutes wait. Even the MRNA shots
have a histamine concern, but it's because of trace materials in
some of the first lots. Later on, they were less concerned, and I
guess the statistics did not indicate much of a problem with the MRNA ones.
But you will still find the policy varies from one vaccine
campaign to another (the pharmacy makes you wait ten minutes).
Blood donation is more likely to be shock.
When I was 17-18, they had a blood donation clinic in the school.
The nurses there, would tell the students not to do anything
too demanding, during the waiting period after donating. They made
you wait, might have had a sugary fruit juice as a beverage.
One young lad (could have been on our football team, I did not
keep track of such things), was determined that he was a super-athlete
and was made of sterner stuff. He was standing near the nurse, said
he didn't have to listen to any of this... and proceeded to sprint
down the school hallway (we were standing in a wide hallway).
After about I would guess fifty feet of running, he passed out
and hit the floor :-) Just about the best demo you could have,
of the need for care after your donation, I would say.
Good work, Mr.Athlete. I didn't stick around to see the
look on his pasty white face, when he came to :-)
I hope the nurse gave him a couple kicks in the bum
for being a fool.
When you're young, you frequently have no idea what shock is.
Later in life, you have enough experiences to be "calibrated"
and you can tell from your symptoms, when it is "brace for impact"
or "find a nice spot for a short sleep on the floor" :-) Once your
systolic drops to about 90 or so, you don't have that many more
feet to go before the crash landing. You can have as little as
five seconds to make up your mind (this is in a case where the
odds are good of shock happening, so shock does not come as a
surprise to you, but the symptoms can still sneak up on you).
Like the kid who ran down the hall.
The reason our football team was not "noteworthy", is they did not
seem to be participating in any "league". And as such, I didn't
care if you wore an outfit with a number on it, it didn't mean
a lot if you weren't actively participating. You might as well
be in the Chess Club :-) I don't remember the reason the team
was not playing. But at least nominally, I suspect the individual
was on the football team. Maybe that's why he felt defensive
about his manhood, and being told he might be a pansy.
Most of the other students thought his address to the
nurse, was out of proportion to the situation. But
the demo, was chefs kiss. Couldn't have trained better in
acting class.
