First responders - people who can save lives by using special equipment to work with the ambulance service - are needed for Heathfield and Waldron.
The Lottery funded group already has five responders trained by South East Coast Ambulance (SECAmb) but needs at least 12 by the end of the year.
A responder (aged from 17-70) uses his or her own vehicle and is given a dedicated mobile phone, a defibrillator, oxygen, other medical kit and a uniform.
All are unpaid volunteers and most have no prior medical background of any kind.
When the ambulance service receives an emergency call it despatches an ambulance as usual but also calls any responder who may be close to the incident.
The patient could be suffering from a heart attack, breathing difficulties, a choking fit or have fallen over and notable to get up. More than 100 incidents of varying kinds have been attended, including two cardiac arrests, from which one patient was successfully resuscitated, and more volunteers are urgently needed.
Each responder costs £1,600 to equip and although there has been generous Lottery and Parish Council support, this vital service still bears ongoing costs.
The next fundraising event is a quiz night at the Star Inn, Waldron from 7.30pm on Monday, March 31.
There will be raffle prizes. Teams can be up to six people and the evening costs £10 per head to include supper.
