What fetal heart rate monitoring actually measures
Fetal heart rate (FHR) surveillance is an indirect measure of fetal oxygenation. Contractions temporarily reduce blood flow through the placenta; a healthy, well-reserved fetus absorbs that stress without difficulty. A compromised fetus does not, and the heart rate pattern changes before permanent injury occurs — which is the entire point of monitoring.
Two methods are used in Quebec hospitals:
- Intermittent auscultation (IA) — periodic listening with a Doppler, appropriate for low-risk pregnancies in spontaneous labour.
- Electronic fetal monitoring (EFM) — a continuous paper or digital tracing, indicated when risk factors are present (induction or augmentation with oxytocin, meconium, prematurity, preeclampsia, suspected growth restriction, prior caesarean, epidural in certain configurations, bleeding, fever, or any abnormal IA finding).
Clinicians interpreting an EFM tracing assess several features together: the baseline rate (normally 110–160 bpm), variability (the beat-to-beat fluctuation that reflects an intact autonomic nervous system), accelerations, and the presence, type and timing of decelerations — early, variable, late, or prolonged. Uterine activity is read alongside the FHR, because excessive contraction frequency (tachysystole) is itself a cause of fetal compromise, particularly when oxytocin is running.
The Canadian standard of care: SOGC Guideline No. 396
Quebec practitioners are measured against Canadian practice, not American practice. The governing document is the *Society of Obstetricians and Gynaecologists of Canada, Clinical Practice Guideline No. 396, Fetal Health Surveillance: Intrapartum Consensus Guideline*** (2020), which replaced the 2007 guideline.
An important distinction for anyone comparing Canadian and U.S. sources: the SOGC classifies EFM tracings as normal, atypical, or abnormal — not by the American three-category (I/II/III) system. That classification drives the required response. An atypical tracing calls for closer evaluation and intrauterine resuscitation; an abnormal tracing calls for prompt action, escalation, and often delivery.
The guideline also sets out the expected toolkit when a tracing deteriorates:
- Intrauterine resuscitation — maternal repositioning, IV fluid bolus, correcting hypotension, reducing or stopping oxytocin, and considering tocolysis.
- Digital fetal scalp stimulation to provoke an acceleration.
- Fetal scalp blood sampling (pH or lactate) where available, beyond 34 weeks, when an atypical or abnormal tracing does not resolve and delivery is not imminent.
- Umbilical cord blood gases at delivery — the SOGC recommends sampling both arterial and venous, because venous blood is mistakenly sampled a meaningful share of the time.
- Contemporaneous documentation, and separate assessment of the maternal heart rate to confirm that the monitor is actually tracking the fetus.
That last point deserves emphasis. Mistaking the maternal pulse for the fetal heart rate is a recognized and recurring error. A reassuring-looking tracing that is in fact recording the mother while the fetus is in distress is one of the more devastating patterns we encounter.
How negligent monitoring happens
In our experience reviewing Quebec obstetrical files, breakdowns cluster into a handful of recognizable patterns:
1. Failing to monitor at all, or at the right intensity. Risk factors present at admission that should have triggered continuous EFM, but IA was used instead — or auscultation was performed at intervals longer than protocol allows.
2. Misinterpreting the tracing. Recurrent late decelerations, minimal or absent variability, or a rising baseline recorded but classified as reassuring. Loss of variability combined with recurrent late decelerations is a classic warning sign of evolving hypoxia.
3. Failing to respond. The tracing is correctly identified as abnormal, but no intrauterine resuscitation is undertaken, oxytocin continues to run, and no attempt is made to confirm fetal status by scalp stimulation or sampling.
4. Failing to escalate. A nurse recognizes a deteriorating pattern; the obstetrician is not called, is called late, does not attend, or attends without reviewing the tracing personally. Communication failures at shift change are a frequent aggravating factor.
5. Oxytocin mismanagement. Augmentation continued or increased in the face of tachysystole with an atypical or abnormal tracing.
6. Delay in delivery. The decision for an urgent caesarean is made, but the decision-to-delivery interval stretches well past the roughly 30 minutes expected for an emergency section — because an OR is unavailable, anaesthesia is delayed, or staff are not assembled.
7. Documentation gaps. Missing tracing segments, unlabelled paper, retrospective charting, or entries that conflict with the tracing itself. In litigation, this cuts both ways — but it is frequently the thread that unravels a defence.
The consequences
Prolonged, unrelieved oxygen deprivation during labour can produce hypoxic-ischemic encephalopathy, which in turn may lead to cerebral palsy, seizure disorders, cognitive and developmental impairment, feeding and mobility difficulties, or death. Evidence supporting an intrapartum cause typically includes a low umbilical arterial cord pH (often below 7.0) with a significant base deficit, an early neonatal encephalopathy consistent with Sarnat staging, the need for therapeutic hypothermia (“cooling,” which must generally begin within six hours of birth), and characteristic patterns on later MRI.
An honest word here, because it matters to how a case is assessed: not all cerebral palsy is caused by events during labour. A substantial majority of CP cases have antenatal or genetic origins, and this is the central argument the defence will make. A credible Quebec claim therefore does not rest on the outcome alone — it rests on demonstrating both a departure from the monitoring standard and a causal link between that departure and the injury.
The Quebec legal framework
Quebec is a civil law jurisdiction. Medical liability is governed by the Civil Code of Québec, principally articles 1457 and 1458, and not by common-law negligence doctrine — a distinction that makes Ontario or U.S. sources unreliable guides for a Quebec family.
To succeed, a claimant must establish three elements on the balance of probabilities:
- *Fault (faute)* — a departure from the conduct of a prudent and diligent professional placed in the same circumstances, judged according to the knowledge and practice available at the time, not with hindsight.
- *Injury (préjudice)* — the bodily, moral and pecuniary harm suffered.
- *Causal connection (lien de causalité)* — a direct and immediate link between the fault and the injury.
Physicians in Quebec owe an obligation of means (obligation de moyens), not an obligation of result. They do not guarantee a healthy baby; they undertake to deploy reasonable care, skill and diligence. The Supreme Court of Canada confirmed the rigour of this framework in *St-Jean v. Mercier*, 2002 SCC 15 — a Quebec case — holding that proving a breach of the standard does not, on its own, establish causation. Each element must be proved independently.
Obstetrical practice is also shaped by the Code of ethics of physicians and by each establishment's own protocols. Internal hospital policies are not automatically the legal standard, but a documented failure to follow a hospital's own written monitoring protocol is persuasive evidence of fault.
Who can be held liable
- The nurse and the establishment. Nurses in Quebec public hospitals are employees. Under article 1463 CCQ, the establishment is liable for faults committed by its employees in the performance of their duties. Since the reorganization of the health network and the creation of Santé Québec, claims against public institutions are now typically directed at the CISSS or CIUSSS operating the hospital, with Santé Québec involved.
- The physician. Obstetricians, family physicians and anaesthesiologists generally practise independently rather than as hospital employees, and are sued personally. They are almost always defended by the Canadian Medical Protective Association (CMPA), a well-resourced national organization — which is a realistic factor in assessing any claim.
- Midwives working in a maison de naissance or hospital, where applicable.
Evidence: the tracing is the case
Obstetrical claims are unusual in that the central piece of evidence is a contemporaneous, machine-generated record made before anyone knew there would be a dispute. Preserving it matters.
A thorough file review will typically assemble:
- The complete EFM tracing (paper strip and/or archived digital record), with time correlation
- Full maternal prenatal, labour and delivery records; nursing notes; the partogram
- Oxytocin administration records
- The neonatal chart, resuscitation record, cord blood gas results, cooling protocol documentation
- Imaging: cranial ultrasound, MRI
- The incident/accident report (form AH-223), where one was completed
- Operating room and anaesthesia records, for decision-to-delivery timing
Quebec health legislation gives patients — and parents on behalf of a minor child — a statutory right of access to their own health record, and establishments must respond within short statutory deadlines. There is also a legal obligation on establishments to disclose to a user an accident that occurred in the course of their care. Requesting the complete record, including the raw tracing rather than a summary, is usually the first concrete step.
Deadlines: the point most Quebec families get wrong
The general prescription period for an action in bodily injury is three years (articles 2925 and 2930 CCQ).

Here is the critical nuance, and it is one that is frequently misstated by sources written for other provinces: in Quebec, prescription is not automatically suspended until a child turns 18. Article 2905 CCQ suspends prescription for a minor only in narrow circumstances — for claims against the child's own representative or custodian, and for bodily injury resulting from an act that could constitute a criminal offence. A conventional medical malpractice claim arising from negligent fetal monitoring generally falls into neither category. Families who assume they have until their child's twenty-first birthday to act are relying on a rule that does not exist here.
—
Some flexibility does exist. Under article 2926 CCQ, where injury manifests gradually or belatedly, the period runs from the day it first appears — which can matter where a developmental impairment is only diagnosed years after birth. Article 2904 addresses situations where it was impossible in fact to act. But these are fact-intensive arguments, not safe assumptions.
The practical takeaway: obtain the medical record and a legal assessment early. Waiting is the single most common way a meritorious Quebec birth injury claim is lost.
What compensation covers
Quebec assesses damages under articles 1607, 1611, 1614 and 1615 CCQ. In a catastrophic birth injury file, the heads of damage typically include:
- Future care costs — attendant and nursing care, therapies, adapted housing and vehicle, equipment, medications. In a lifetime-care case, this is by far the largest component, and it is not capped.
- Loss of future earning capacity, projected from actuarial and vocational evidence.
- Non-pecuniary damages for pain, suffering and loss of enjoyment of life, subject to the Supreme Court of Canada's indexed ceiling from the 1978 trilogy — in the range of roughly $460,000–$470,000 in recent years, and adjusted annually.
- The parents' own claim for moral damages and, where applicable, expenses, extraordinary care and lost income.
Article 1615 CCQ also permits a court, in bodily injury cases, to reserve the plaintiff's right to claim additional damages within three years of judgment where the future evolution of the condition cannot yet be determined — a provision of real significance where a young child's prognosis remains uncertain.
Claims of this magnitude proceed before the Superior Court of Québec, and depend heavily on expert evidence from obstetrics, neonatology, paediatric neurology, life-care planning and economics.
Frequently asked questions
How long do I have to sue for a birth injury in Quebec?
Generally three years. Unlike some provinces, Quebec does not broadly suspend the clock until a child reaches majority for ordinary medical malpractice claims. Certain rules can affect the starting point where an injury manifests later, but you should not assume additional time is available. Get an assessment promptly.
Does an abnormal fetal heart tracing prove malpractice?
No. An abnormal tracing is common and often resolves. Liability turns on whether the team recognized it, responded appropriately, escalated, and delivered in time — and whether the failure to do so caused the injury.
My child has cerebral palsy. Was it caused by the delivery?
Not necessarily. Most cerebral palsy has causes unrelated to labour. Cord blood gases, the neonatal course, whether cooling was required, and MRI findings are the objective markers used to distinguish intrapartum injury from other causes.
Who pays if the claim succeeds?
Typically the physician's defence organization (the CMPA) and/or the public establishment and its insurers, depending on which parties are found at fault.
What does it cost to pursue a claim?
Many Quebec firms handle birth injury files on a contingency basis, with expert costs advanced. Ask about the fee structure in writing at the outset.
Can I still act if the hospital already told me nothing was done wrong?
Yes. An internal review is not a legal determination, and it is not binding on you. An independent review of the raw tracing by outside experts frequently reaches a different conclusion.
