It was a Saturday. I was on an overtime duty in an RRV, covering a rural patch, when the call came in. Patient with traumatic injuries. Rural setting. I started moving immediately, calling up control as I went, asking what else was coming.
A double-crewed ambulance, they told me, but at a distance, and HEMS had been activated. I would be the first on the scene. Give a sitrep when I get there.
I acknowledged, put the radio down, and focused on the road ahead. The countryside moved past the windows in the way it does on a blue-light run — fast and peripheral, scenery rather than landscape, something to navigate around rather than look at.
The closer I got, the longer the traffic backed up. That told me something before I had seen anything. Traffic backs up when something has stopped the ordinary rhythm of a road, and out here, on a rural stretch with fields on both sides, there was nothing ordinary about what had stopped it.
I felt it in my stomach the way you always do with calls with few details or those where it sounds serious – that nervous feeling that settles somewhere below the ribs when a job announces itself before you arrive. It does not go away with experience. You just learn to work alongside it.
I parked up, grabbed my bag, and went to work.
Alone at a scene like that, with the ambulance still quite a distance away and HEMS somewhere in the air behind me, you do what you were taught to do and what you’ve learnt from your past experience. Bystanders were there. I directed them, kept them useful, and got on with the assessment.
I started my primary survey, then began doing what was deemed important. Oxygen mask on, working on IV access, talking to my patient, and trying to keep things as steady as circumstances allowed. The patient was conscious. Injured but present, responding, and still in the conversation with me.
You keep talking to a patient in those circumstances because it matters to them and to you. Every answer is information. Every response tells you they are still there.
When you have been in this job long enough, you learn to listen for the sounds that mean something is shifting. The cry of a baby when you have been told there are no signs of life. A groan from someone reported unconscious.
The sound of a front door opening when you have been working in a house on your own, and you know that help has arrived. These sounds do something to your body before your brain has fully named them. You feel them first — somewhere in your chest or your shoulders or your hands — and your body starts adjusting before your conscious mind has finished processing.
Out here, on a rural road with one pair of hands and a patient who needed more than I could give alone, the sound I was listening for was different from all of those.
Somewhere behind me, still on the road, the ambulance was coming. You hear a siren like that differently when you are the one waiting for it. It starts as nothing — a suggestion at the edge of things, a sound you are not sure is real or imagined.
Then it grows. Slowly at first, rising out of the distance in stages, getting louder and more certain with each passing second until there is no mistaking it. It is the sound of someone coming to help you.
It does something to your shoulders when you hear it. Something in you that had been braced starts to ease, just slightly, just enough to keep working. The siren in the distance is not just a sound. It is a message. I am coming. Hold on.
Then you hear a heavy, rhythmic, piercing wop-wop-wop. The mechanical sound that cuts through engine noise, through wind, through everything else and lands somewhere in your chest before your brain has caught up with what it means.
I looked up from what I was doing, and the HEMS helicopter came circling above the fields like an eagle spying on its prey. I looked at my patient. “Here comes the cavalry,” I said.
I meant it as much for myself as for them. We both needed to hear it.
What landed with the helicopter was not just a machine. It was a capability I did not have. The HEMS doctor and critical care paramedic (CCP) came off the aircraft and moved with the kind of purpose that comes from doing this repeatedly — in fields and on roadsides and at the ends of lanes that most people never travel.
A critical care paramedic is not simply another paramedic who arrived on a helicopter. The title sounds like a variation on a theme. It is not. They carry drugs that standard paramedics do not carry. They perform interventions that standard paramedics are not trained to perform.
They operate at a clinical level closer to what you would find in a resuscitation room than anything that belongs on a roadside. I assisted the doctor whilst the CCP did what they are specifically trained to do — drugs and decisions and procedures that sit beyond my scope, delivered at the side of a rural road as if that were the most natural thing in the world.
I watched, and I helped, and I was glad they were there.
The ambulance eventually arrived during this. Between all of us, the patient was stabilised and packaged. A decision came quickly: given the nature of the injuries, the road to Belfast by ambulance was the wrong road. Too far. Too slow.
The patient was loaded onto the helicopter. The blades started up again — that same wop-wop-wop, that same mechanical percussion — and they lifted off. As they climbed and turned and shrank into the distance, the sound faded by degrees.
The fields came back. The road came back. The birds, somewhere. My colleagues and I stood there and watched until the helicopter was gone, and then the world was just a rural road again, quiet and ordinary, as if nothing had happened on it at all.
It always surprises me that it returns to normal. The speed of it. One moment, the air is full of noise and motion and controlled urgency; then it is just a road, traffic edging forward again, and people getting back into their cars.
You are left with the equipment to pack, the paperwork to start, and the quiet that follows something significant. You do not always have words for it. You do not always need them.
HEMS — the Helicopter Emergency Medical Service — exists because geography and time are clinical problems. In Northern Ireland, the distances involved in pre-hospital care are not theoretical. They are real, and they carry consequences.
A patient on a rural road an hour from a trauma centre is in a fundamentally different position to a patient two minutes from an emergency department, and no amount of skill from a ground crew can fully bridge that gap. The skill is not the issue. The time is.
HEMS compresses time. It also delivers clinical capability that the time problem alone does not resolve. It does both things simultaneously, and that is why it exists and why, when it works, it works in a way that nothing else does.
The service in Northern Ireland operates under the Northern Ireland Ambulance Service and is staffed by a combination of consultant-level doctors and critical care paramedics. It runs on a response model that prioritises the most critical calls – the jobs where the gap between what a ground crew can offer and what the patient needs is the widest.
It does not go to every serious call. It cannot. The aircraft is a single asset covering the whole of Northern Ireland, and deployment decisions are made in real time using clinical criteria that weigh need against availability.
There are calls you want it for, and it cannot come. Weather grounds them, although they can travel by car. Operational demands take them elsewhere. The geography that makes HEMS necessary is the same geography that sometimes makes it unreachable. You learn not to build your clinical plan around an asset whose arrival you cannot guarantee.
The HEMS role is worth understanding on its own terms because the public tends to focus on the helicopter and misses the person stepping off it. When people see HEMS land near a scene, they see the aircraft. They think about the speed of it, the drama, and the way it clears a field and sets down on a road as though roads were always meant for that.
What they often do not see is the clinical capability that walks off it. Both the doctor and the critical care paramedic are trained beyond the standard level to deliver interventions that sit outside the normal pre-hospital scope. Sedation, anaesthesia, and advanced haemorrhage control, as well as surgical airway management and procedures, which would normally be done in an emergency department setting.
These are not routine extensions of standard practice. They are a different tier entirely, acquired through further specialist training and developed through deployment over time. When HEMS lands at your scene, the aircraft is the transport. The capability is human.
Not every call goes the way the first one did. A second call stays with me for different reasons.
We were with a patient who had become severely agitated — initially unresponsive with a quivering seizure and a fall, but by the time we were fully into the assessment, the agitation was the dominant problem. The fire service was with us. The patient needed to leave the property, but his level of agitation made it unsafe.
He needed sedation before anyone could do what needed to be done. Sedation at that level, in that setting, is not something I carry. It is not something I am authorised to administer. HEMS was the right call.
They carry the drugs. They hold the clinical authority to use them. We activated, and they said they were on their way.
I went back to the patient and kept working. The fire service waited. We talked quietly between ourselves, the way you do when you are holding a situation rather than resolving it, keeping things contained until the right resources arrive.
By the time the HEMS doctor and CCP arrived, the patient had started to settle. Not dramatically, not completely, but enough. Enough that sedation was no longer necessary. Enough that the fire service could move him safely without it.
I apologised. I told the doctor I was sorry for bringing them out unnecessarily. The doctor looked at me and told me not to worry about it. Given what I had described at the time of the call, activating HEMS was exactly the right decision.
That a patient who had improved in the interval — a crew who had managed — was precisely what they were there for. They said it without irritation, without the weight of a wasted journey. They had meant it, and I heard it.
I did not have long to sit with that — the patient still needed the hospital, and I had a job to finish. But it settled something.
There is a version of this work in which you second-guess yourself when a call resolves without drama, and the situation that improved starts to feel, in retrospect, like evidence that you overreacted. The doctor’s words were a reminder that pre-hospital medicine does not run on outcomes alone.
The decision to activate HEMS is not made with the benefit of hindsight. It is made in the moment, with the information available, under pressure, in the interest of a patient whose condition could go anywhere from where it currently sits.
You call it when you believe it is needed. The situation may change before they land. That is not a failure of judgement. That is the job. The right call and the good outcome are not always the same event. You must be at peace with that, or this work will hollow you out.
The relationship between a ground crew and HEMS is not the hierarchy that people sometimes imagine — the helicopter arriving to correct the crew who could not manage it. It is a collaboration shaped by capability and circumstance.
When HEMS arrives, clinical leadership transfers appropriately, and you become part of a wider team rather than the sole practitioner at the scene. That shift is not a demotion. The system is working as it should.
The ground crew brings scene knowledge, patient history, and any stabilisation already achieved. HEMS brings what comes next. The two things fit together. Neither is sufficient without the other, and experienced practitioners on both sides understand that without saying it.
There are calls where you stand on a dark rural road in the rain, the asset you most need is unavailable, and you work with what you have. You do not stop. You adapt.
You push the clinical ceiling as far as your training allows, make the best of what is in your bag and in your head, and do not let the patient see that you are doing the calculations.
Those moments clarify something that gets taken for granted on the days when everything arrives, and everything works. When the helicopter does come, the relief is not simply emotional — though it is that too, absolutely, and there is no point pretending otherwise. It is clinical. It changes what is possible for the person in front of you.
It is the difference between one pair of hands on a roadside and what a trauma team can deliver, made available in a field in Northern Ireland because someone built a service capable of bringing it there.
I think about the first call often. The tailback on the road. The nervous feeling below the ribs. The IV access, the talking, the waiting, the listening for something in the air. The siren is rising in the distance.
And then the other sound – that heavy, rhythmic, piercing wop-wop-wop – cutting through the quiet of a Saturday morning and the helicopter circling high and fast above the fields. The patient loaded. The helicopter rotor blades starting again. The lift and the turn and the shrinking shape of it, climbing away until the fields and the road and the ordinary Saturday came back around us.
HEMS sends a follow-up after jobs like that. Injuries sustained. Where the patient ended up: ICU, theatre, or straight to surgery. You read it on your email between calls, and it lands differently than you expect.
Not closure. Something more complicated than that. You know now what was wrong. You understand, for the first time, exactly what you were managing on that road before you fully knew what you were managing.
But the email stops there. The health system is long, and the patient travels through parts of it you will never see, and at some point, their journey and yours stop running alongside each other. You were there for one stretch of road.
My colleagues said nothing when they left. There was nothing that needed saying. We had both been part of something that had gone as well as it possibly could, and we both knew it, and sometimes that is enough.
Then I went back to the car. There was still work to do. There always is.
