When the First Aid course instructor has never treated a patient
Here is an interesting one. Recently during the course a site manager was stood listening at the back of the room. During the session he heard me say that when we lose a pint of blood in trauma it is replaced normally within 24 to 48 hours (plasma) and fully back up and replaced after 4 to 6 weeks.
On his recent First Aid Course he raised this with his instructor who corrected him sternly that this was rubbish and it takes 3 months minimum. That student decided not to argue but did decide he wouldnt get involved in the session with more questions for fear of a repeat embarrassment.
Today he took me to one side to reassure him he had heard me correctly during my session.
So for that site manager and for the first aid trainer.
How long will it take to replenish the pint of blood I donate?
The plasma from your donation is replaced within about 24 hours. Red cells need about four to six weeks for complete replacement. That’s why at least eight weeks are required between whole blood donations.
If you want the link for this question and answer email me.
Sad that by answering the question with admonishment and embarrassment he lost that student.
