AMID the unfolding tragedy of four deaths on a ride at Dreamworld on Tuesday, an ambulance officer’s seemingly heartless description of the victims’ injuries had social media in uproar.

But seasoned paramedic Gavin Fuller, facing the media just two hours after no doubt one of the most traumatic scenes of his career, was merely using a widely used medical term when he described the four victims as having suffered “injuries incompatible with life”.

It caused a social media maelstrom, with many attacking the Gold Coast's acting supervising officer — and the media for reporting it — for a seemingly cold description so soon after four deaths.

But the clearly shaken, senior officer, facing a live national television cross fresh from leaving the grisly scene, was using a clinical term commonly used by medical professionals, police and other emergency services.

"Suffered injuries incompatible with life." Another death sentence. For words. @SENNews — Tony Tea (@AfterGrogBlog) October 25, 2016

Why ambulance and police officers use phrases like "sustained injuries incompatible with life" is beyond me. Such cold, impersonal language — Mark Ludlow (@M_Ludlow) October 25, 2016

I also can't believe the journalism around the tragic event. These poor families. "Injuries incompatible with life" - what? And "The dead" ? pic.twitter.com/0fVjeAKYJt — Ruby Rose (@RubyRose) October 25, 2016

Reading about #Dreamworld theme park deaths. Spokesperson: "they sustained injuries incompatible with life" - what a horrible phrase. — Geoff Robjent (@robjent) October 25, 2016

Unknown to many was that the term gave a sad insight into the extent of the injuries the victims suffered.

When injuries are deemed by paramedics to be so severe that they are “incompatible with life”, CPR is deemed a futile exercise.

The Queensland Ambulance Service official clinical practice guidelines for resuscitation outline a number of instances in which CPR should not be attempted.

They include where the patient has sustained injuries that are “totally incompatible with life”.

According to the document, such injuries include decapitation, cranial and cerebral destruction, hemicorporectomy (where the body is amputated below the waist), incineration or foetal maceration (foetal death).

Issues with media coverage so far 1."incompatible with life" is a medical phrase, not #Dreamworld responders being dismissive of tragedy. — Epiphanater (@epiphanater) October 25, 2016

@Veteran_Status said "injuries incompatible with life". Give me a break the poor bloke has had a tough day. People should calm their farm — Jon Tuxworth (@Tuxy81) October 25, 2016

If you were wondering about that somewhat heartless-sounding "injuries incompatible with life" term, it's a technical one. pic.twitter.com/ymSQJkYBHX — Philip Calder (@philipjcalder) October 25, 2016

Many social media users rushed to defend Mr Fuller’s use of the term on live television.

A 32-year-old woman and her 35-year-old brother were killed in Tuesday afternoon’s tragedy, which happened on the Thunder River Rapids Ride.

The man’s 38-year-old male partner also died. All three were from Canberra.

The woman’s 12-year-old daughter was thrown clear of the ride and watched in horror as her mother and uncles perished.

Another unrelated woman, 42, from Sydney was also killed.

Her 10-year-old son was also thrown free from the raft and watched his mother die.

More than 30 detectives are investigating the incident.

Dreamworld remains closed today as the investigation continues.

Earlier, Queensland Police Service Assistant Commissioner Brian Codd said emergency services who rushed to Dreamworld following the incident had been left badly shaken by the scene that confronted them.
