CFRs respond to emergency 999 calls, providing vital support in life-threatening situations, including cardiac arrests and trauma cases.
Trained by the Ambulance Service, they work without pay in both urban and rural areas when available and in their own time.
Volunteers are wanted in Bromyard, Kington and Leominster.
In addition to emergency response, CFRs support their local schemes through community engagement such as fundraising and promoting CPR and defibrillator awareness.
Tim Cronin, regional community response manager, said: "Maybe you've added 'volunteering' to your list of New Year's Resolutions? If so, this position could not be more perfect.
"We're recruiting for CFRs at multiple locations across the region and are looking for kind, compassionate people who are committed to helping others in their local community."
Applicants should have a good level of education, basic IT skills, strong communication skills, and a good level of physical fitness.
They must also have held a full UK driving licence for at least one year with no more than six penalty points.
