In Canada, paramedics administer blood and blood products.
In Saskatchewan, paramedics carry and administer blood - a friend of mine was given blood in his home before being transported by ambulance to the hospital.
This is from a training module for Portage College of Paramedics in Alberta:
The incidents of administering blood products in the field are very rare, except
perhaps in the air ambulance setting. However, with the trend of increased patient
transfers and specialized health care centers, the frequency Paramedics are
required to initiate and monitor the transfusion of blood products is increasing. As
a result, the practitioner must have a strong understanding of the different types of
blood products; the importance of ensuring the blood product is administered to
the intended recipient, the process of initiating and monitoring blood products and
assessing the patient for adverse reactions.
Where this becomes pertinent for Canadians, is disclosed in the following article:
Christian medical professionals are challenging Ontario's College of Physicians and Surgeons in court over a policy that requires doctors to provide or at least refer medical services, even when they clash with personal values.
In a statement of claim filed in Ontario's Superior Court of Justice, two groups — the Christian Medical and Dental Society of Canada and the Canadian Federation of Catholic Physicians' Societies — and five individual doctors say the college's policy violates their rights under the Charter of Rights and Freedoms.
At issue is the Ontario medical regulator's vote earlier this month to update its professional and human rights policy.
The new Ontario policy requires doctors unwilling to provide certain care, such as prescriptions for contraception, to refer patients in good faith to a "non-objecting, available, and accessible" physician. The policy also says in medical emergencies, the doctors would be required to perform procedures themselves.
Doctors who violate the policy could face disciplinary action, the college policy states.
Would paramedic be an occupation be that one of Jehovah's Witnesses simply cannot accept, knowing fully well that you would be in a likely position to administer blood.
I believe this was directly answered in one of the Watchtowers from back in the 80s or 90s, I think. I don't know the exact quote, but it could have been a question from readers - whether someone working in health care (doctor or nurse) could administer blood. The answer was 'yes'.
