COMMUNITY first responders in Hornsea are urging the ambulance service to use them 24/7.
The responders team has to log on to the ambulance service system to be called out on jobs, but has asked to be called whether it is logged in or not.
Hornsea Inshore Rescue, whose crew also saves lives at sea, are asking to be on constant call-out, but to be contacted through their boathouse phone number or pager system.
Sue Hickson-Marsay, of the rescue team, is concerned they are missing the opportunity to be called out.
"If no one logs on, then we aren't getting the calls from the ambulance service when we could be helping," she said.
"We are offering our services to Yorkshire Ambulance Service (YAS) 24/7, but asking them to either phone us up or page us if we can help. Currently, they are not using us as much as they could."
The concerns were raised when it was revealed the first responder group was not called when Iain and Simon Poole's dad Raymond died.
Mr Poole's sons tried desperately to resuscitate him for 30 minutes, before paramedics arrived after he had collapsed. He was later pronounced dead.
Iain said: "We have spoken to many people who didn't understand why, when we have so many valuable resources in Hornsea, none of them were called upon to support us in our time of need.
"As a family, we feel this is a positive move towards changing the way these volunteers are managed and, hopefully, saving another family from the heartache we continue to suffer at the loss of our father.
"It does beg the question that if any of these resources had been deployed to help our family, would we have had a more positive outcome?"
The YAS trains first responders in basic life-support skills, cardiopulmonary resuscitation (CPR), the use of an automated external defibrillator and the administration of oxygen.
When a 999 call is received by the service, an ambulance response is dispatched.
At the same time, a community first responder on call in the area can be alerted and asked to assist, to ensure help reaches the patient as quickly as possible.
Ian Walton, associate director of resilience and special services at YAS NHS Trust, praised the role and said the Hornsea Inshore Rescue team had attended 42 incidents since April.
"Each team is assigned a call sign and needs to book on to the YAS emergency operations centre system as an available resource to attend appropriate medical emergencies in the area," he said.
"This procedure only takes a few seconds and allows us to carefully monitor the availability and whereabouts of our volunteers and is essential from a safety perspective.
"At the time of the incident involving Mr Poole, no first responders in the local area were booked on with our emergency operations centre."
