If the anaesthetic caused you to stop breathing properly — was that a mistake, or just a risk you accepted?
You went in for a procedure. Something went wrong with the anaesthetic. You stopped breathing properly — or you weren’t breathing at all — and the recovery was not what anyone told you to expect. Now you are trying to work out whether that was an unavoidable complication, or whether someone made a mistake.
That distinction matters. It is also answerable. The records will show what the anaesthetist knew, what they did, and what a competent practitioner in the same situation was required to do instead.
This article will help you understand what anaesthetists are required to do, where the failures that cause respiratory distress typically occur, and what to look for in your own situation.
What the anaesthetist was required to do
Anaesthesia is not passive. The anaesthetist actively manages your airway, your breathing, your drug doses, and your response throughout the procedure. Australian law requires that they do this to the standard of a competent specialist anaesthetist — not a perfect one, but a careful and skilled one.
That standard includes assessing your airway before the procedure, anticipating difficulties, monitoring your oxygen levels continuously, and responding immediately when something changes. It also includes giving you enough information beforehand to make a real decision about the risks specific to you.
A patient with a documented history of sleep apnoea undergoes elective surgery. The anaesthetist does not adjust the sedation protocol or arrange post-operative monitoring beyond the standard recovery room. In recovery, the patient’s oxygen levels drop. Staff do not notice for several minutes. The patient sustains a hypoxic brain injury. The anaesthetist’s pre-operative assessment was in the notes. The adjustment was not.
Where it goes wrong
The anaesthetist failed to assess a known airway risk
Before any procedure, the anaesthetist must review the patient’s history for factors that complicate airway management — obesity, sleep apnoea, a short neck, previous difficult intubations, or certain medications. When the anaesthetist skips or rushes this assessment, they go into the procedure without a plan for what they already had reason to anticipate.
A difficult intubation that injures the airway, or a period of oxygen deprivation that follows a failed first attempt, is not automatically a known risk. It may be the direct consequence of inadequate preparation.
The monitoring failed — or the response to it did
Continuous monitoring of oxygen saturation is not optional. When the monitor alarms and no one acts quickly enough, or when the alarm is silenced without investigation, the failure is not the machine’s — it belongs to the team. Delayed recognition of respiratory distress during or after anaesthesia is one of the most common patterns in anaesthesia negligence claims.
The records will show the timestamps. They will show when the saturation dropped, when the alarm triggered, and when anyone intervened. That sequence is often where the case turns.
The drug dose was wrong for this patient
Anaesthetic agents suppress breathing. The dose must be calibrated to the individual — their weight, their age, their existing conditions, and the other drugs they are taking. An anaesthetist who uses a standard dose without adjusting for a patient’s specific profile, or who fails to account for a drug interaction that was documented in the notes, has not met the required standard.
Respiratory depression caused by an excessive or poorly managed drug dose is not a risk the patient accepted. It is a failure of clinical judgment.
- You experienced breathing difficulties, oxygen deprivation, or respiratory arrest during or immediately after a procedure — and no one gave you a clear explanation of why.
- You have a condition — sleep apnoea, obesity, a previous difficult intubation — that the anaesthetist knew about, and the complication relates directly to that condition.
- You woke up in intensive care, on a ventilator, or with a longer recovery than the procedure warranted — and the treating team described it as “one of those things.”
- You were not told before the procedure about a specific respiratory risk that applied to you — only given a general consent form.
- You suffered lasting harm — cognitive changes, cardiac damage from oxygen deprivation, or a prolonged recovery — that your treating doctors have not fully explained.
- This happened years ago and you have only recently started to connect what occurred with the possibility that something was done wrong.
The records — not anyone’s recollection — will answer these questions. What the anaesthetist documented before the procedure, what the monitoring showed during it, and what the post-operative notes record are the evidence that matters.
Time limits apply to medical negligence claims in Australia and vary by state and territory. Many people wait years before looking into what happened. That delay is understandable — but it is worth knowing where you stand before the limitation period closes.
What happens next
A legal review of an anaesthesia claim starts with the records — the pre-operative assessment, the anaesthetic chart, the monitoring data, and the post-operative notes. Those documents tell a story that is independent of what anyone remembers or was willing to say at the time.
The goal is an honest answer. Not to blame anyone for the sake of it — but to establish whether what happened to you was avoidable, and whether the law gives you a path forward.

Dr Rosemary Listing is a lawyer specialising in medical negligence claims, with a PhD in medical negligence. She practises through Peter Evans & Associates, servicing clients across Australia.
Her background allows her to read anaesthetic charts and monitoring records — and then apply the law to what she finds. For anaesthesia claims, that perspective matters: the failures that cause respiratory harm often sit in the gap between what the pre-operative assessment documented and what the anaesthetist actually did with that information.
Dr Listing’s work is focused on giving people an honest answer about whether what happened to them was avoidable. Many people wait a long time before looking into it. She understands why and applies a sensitive and caring approach to all her clients’ cases.
