A "One punch can kill"-style campaign should be considered for the risks of choking in a domestic violence situation, a Queensland coroner says.
Coroner David O'Connell made the recommendations while handing down his findings following an inquest into the death of Tracy Ann Beale in Gladstone in 2013.
Ms Beale died after being restrained by her husband James Andrew Beale in a choke hold during a domestic violence situation, Mr O'Connell found.
Mr Beale told police his wife had woken him up and repeatedly hit him, and he said he placed her in a choke hold to "calm her down".
Mr Beale was charged with murder and committed to stand trial on a charge of manslaughter, but it did not proceed to trial as the Director of Public Prosecutions withdrew the charge.
Mr O'Connell found the cause of death was the choke hold, which likely triggered a vasovagal attack - causing heart rate and blood pressure to drop. Ms Beale was more susceptible to the fatal effects of the attack due to an underlying condition of a dilated cardiomyopathy and the fact she had consumed alcohol.
"What I am able to conclude is that the medical evidence makes clear that the force of the restraint was not severe, and the duration of the restraint was not prolonged," he wrote in his findings.
"What that highlights is that there is a very real danger in any form of neck compression as it can lead to sudden, and fatal, consequences."
Mr O'Connell said the inquest also raised the question of whether a community education program should be held on the dangers of strangulation, with comparisons made with the "One punch can kill" campaign.
"Clearly neck compression (however it occurs) carries with it dangers, in fact possible fatal consequences," he said.
"The government should consider if it is appropriate for there to be a similar-style community education or awareness program of the dangers of choking or strangulation."
Mr O'Connell also recommended that Attorney-General Yvette D'Ath review the offence of choking or strangulation in a domestic setting, to determine if it adequately dealt with the vasovagal reflex.
Professor Heather Douglas told the inquest the offence possibly overlooked the circumstances of the Beale case, which involved a reflex cardiac arrest or vasovagal reflex.
"Accordingly the legislation is likely deficient in dealing with this certain aspect of the neck compression situation," Mr O'Connell said.
A spokeswoman for Ms D'Ath said the coroner's findings would be given due consideration after the recommendations were forwarded to her office.
In 2015, the Palaszczuk government introduced the offence of strangulation to the Criminal Code, as recommended by the Not Now, Not Ever report into domestic and family violence.
Women's Legal Service Queensland chief executive Angela Lynch said the service would support a broader community education program on domestic violence risk factors, including strangulation, sexual violence, extreme sexual jealousy, escalation violence and separation, which can trigger violence.
Police told the inquest that two people were charged with strangulation in Queensland every day.
