How Electronic Fetal Monitoring Failures Can Lead to Birth Injury Claims

August 23, 2025

Electronic Fetal Monitoring (EFM) is the definitive tool hospitals use to track a baby’s status during labor and delivery. The EFM strip—capturing every heartbeat and contraction—records unmistakable signs of fetal distress in real time. When providers miss, ignore, or misinterpret these warning signs, preventable injury often follows. In birth injury litigation, the EFM record is the central piece of evidence showing when and how the harm occurred.

Birth injuries impose lasting financial and emotional demands on families. A successful claim ensures access to lifelong medical care, specialized therapies, adaptive equipment, and the ongoing support your child deserves. Every detail in the EFM record drives accountability and answers.

Wapner Newman’s legal and medical teams conduct an exhaustive review of EFM strips and all related hospital records to pinpoint missed opportunities for intervention. We take on the investigation and legal battle for your child’s future, so you remain focused on your family.

What is Electronic Fetal Monitoring, and Why is It Used?

During labor, two sensors are typically placed on the mother’s abdomen with elastic belts. One sensor, using ultrasound, tracks the baby’s heart rate. The other measures the frequency and duration of contractions by sensing the tightness of the abdominal wall. This information is then displayed on a screen and usually printed on a long paper strip.

The primary goal of EFM is to detect signs of fetal distress, as this may be an indication that the baby may not be receiving enough oxygen. An interruption in oxygen supply, even for a short period, risks leading to permanent brain damage and conditions like cerebral palsy. The monitoring is designed to give doctors and nurses an early warning, allowing them to intervene by providing oxygen to the mother, changing her position, or, if necessary, performing an emergency C-section to prevent a permanent injury.

The Two Types of Monitoring

External Monitoring: This is the most common method, using the belts and sensors placed on the abdomen. It is non-invasive and used in the vast majority of labors.
Internal Monitoring: This is a more direct and precise method where a tiny electrode is attached to the baby’s scalp after the mother’s water has broken. It is generally used when external monitoring is not providing a clear or reliable reading.

The Data It Provides

The machine generates a continuous tracing, either on a screen or a paper strip. This “strip” shows two distinct lines: the top line represents the fetal heart rate, and the bottom line shows the pattern of uterine contractions. Medical professionals are trained to interpret the relationship between these two lines, looking for patterns that signal the baby is either healthy and tolerating labor well or is in distress and needs help.

The Standard of Care: What is a Medical Team Required to Do?

In any medical malpractice case, the central question is whether the healthcare provider met the “standard of care.” This refers to the level of skill and attention that a reasonably competent healthcare professional would provide in a similar situation. It is a benchmark for competence and diligence.

National organizations have established clear guidelines that act as a measuring stick for performance in the delivery room. The National Institute of Child Health and Human Development (NICHHD) provides standardized guidelines for interpreting EFM patterns. These guidelines were created to establish a common language and set clear expectations for all obstetric professionals across the United States, ensuring that a fetal heart rate pattern is interpreted the same way in Philadelphia as it is anywhere else.

The core responsibility of the medical staff extends far beyond simply attaching the monitor. The standard of care requires them to:

Correctly interpret the data based on the established NICHHD guidelines.
Recognize the warning signs of fetal distress as they appear on the monitor.
Communicate any concerns clearly and effectively up the chain of command, such as a nurse alerting the attending physician to a troubling pattern.
Act in a timely manner to address the distress and prevent injury.

A failure at any one of these steps could be considered a breach of the standard of care.

How Do EFM Failures Happen?

In most birth injury cases involving fetal monitoring, the issue is rarely a technical malfunction. Instead, the injury typically occurs because of human error in interpreting or responding to the clear information the machine provides.

These can happen at several points in the process:

Misinterpretation: This is one of the most frequent points of failure. An inexperienced nurse, an overworked resident, or a distracted doctor might misread the signs on the EFM strip. Even among experts, there can be disagreement on interpretation, which highlights the high level of skill required. While EFM has a high false-positive rate, a trained professional must be able to distinguish a true emergency from a false alarm.
Delayed Response: The medical team might see the warning signs but fail to act with the necessary urgency. In cases of oxygen deprivation, a delay of just a few minutes is the difference between a healthy baby and a child with a lifelong brain injury like cerebral palsy. This delay is a common factor in many successful birth injury claims.
Communication Breakdown: The hospital’s chain of command is designed to ensure patient safety, but it can fail. A nurse might see a troubling pattern but fail to notify the doctor, or a doctor might dismiss a nurse’s valid concerns without proper evaluation.
Ignoring the Data: In some tragic cases, alarms from the monitor are ignored or even turned down due to “alarm fatigue.” In a busy labor and delivery unit with constant beeping, staff can sometimes become desensitized and fail to react to a warning.

Connecting the Dots From a Fetal Heart Strip to a Birth Injury

For a medical malpractice claim to be successful, we must prove causation. This is a legal principle that means we have to draw a direct and provable line from the medical team’s failure, or the breach of the standard of care, to your child’s specific injury.

The EFM Strip as the Story’s Narrator

The EFM strip is the primary piece of evidence used to establish this crucial link. It tells an objective, minute-by-minute story.

Here is what to look for:

Baseline Heart Rate: A healthy baby’s heart rate should be within a normal range, typically 110-160 beats per minute (bpm). A rate that is consistently too fast (tachycardia) or too slow (bradycardia) is a major red flag.
Variability: Healthy babies have small, irregular fluctuations in their heart rate, which appear as a jagged, “variable” line on the strip. This shows a healthy, responsive nervous system. A flat line with minimal or no variability is an ominous sign of potential distress.
Accelerations: Brief, temporary increases in the baby’s heart rate, often in response to movement, are reassuring signs of well-being.
Decelerations: These are drops in the fetal heart rate. We pay extremely close attention to when they occur in relation to contractions. So-called “late decelerations,” which is a drop in heart rate that begins after a contraction has already peaked, are particularly dangerous signs of fetal distress and insufficient oxygen.

The Controversy and Complexity of EFM

While EFM is used in the vast majority of U.S. hospitals, its overall effectiveness is a subject of ongoing debate within the medical community.

The Risk of Over-Intervention

Studies have shown that the use of continuous EFM in low-risk pregnancies does not significantly reduce the rate of cerebral palsy or perinatal death. However, its use has been linked to a higher rate of interventions. Research suggests it may increase the rate of C-sections and operative vaginal deliveries (using forceps or a vacuum).

How We Investigate a Birth Injury Claim Involving Fetal Monitoring

The role of our firm is to take this complex investigation completely off your shoulders so you can focus on your child and family. Here’s what that looks like:

Step 1: Gathering Every Piece of the Puzzle

We begin by methodically collecting all relevant medical records. This includes the complete prenatal record, the full labor and delivery chart for both mother and baby, and most importantly, the original EFM strips. We handle this entire process in full compliance with patient privacy laws like HIPAA.

Step 2: A Deep Dive with Medical Professionals

We collaborate with a network of respected medical professionals, including obstetricians, labor and delivery nurses, and neonatologists who review the records with us. They help us determine if the standard of care was breached and if that breach directly caused the injury.

Step 3: Calculating the True Cost (Damages)

A serious birth injury is a lifelong condition. We consult with life care planners, economists, and vocational experts to calculate the full, true cost of your child’s future needs. The compensation sought to cover these costs is called damages and may include:

Past and future medical bills
Physical, occupational, and speech therapy
In-home nursing care
Special education needs and tutoring
Mobility aids, wheelchairs, and home modifications
Pain and suffering and loss of life’s pleasures

Step 4: Pursuing Accountability

Once we have built a strong, evidence-based case, we pursue compensation from the responsible hospital and medical providers. This process often begins with negotiation, but we prepare every single case with the thoroughness required for trial.

Frequently Asked Questions About EFM and Birth Injury Claims

How can I get the EFM strips from my delivery?

Under federal law, you have a right to your medical records, including the EFM tracings. You can request them directly from the hospital’s medical records department. However, as part of our investigation, we will formally request the complete, certified records on your behalf to ensure we receive every relevant document without delay.

The nurses said the readings were “reassuring.” Can I still have a case?

Yes. What was said verbally in the delivery room and what the EFM strip actually shows can be two very different things. Staff may use reassuring language to prevent panic, or they may have genuinely misinterpreted the data at that moment. The strip itself is the objective evidence, and its story is the one we will rely on to build your case.

How long do I have to file a birth injury claim in Pennsylvania?

In Pennsylvania, the statute of limitations for medical malpractice is generally two years from the date the injury was discovered or reasonably should have been discovered. However, for a minor, this rule is extended. A claim can be filed up to two years after the child’s 18th birthday, meaning until their 20th birthday.

What if my baby’s injury was caused by something other than fetal distress?

EFM failures are just one potential cause of preventable birth injuries. Other causes may include the improper use of forceps or a vacuum extractor, errors in managing a high-risk pregnancy (like undiagnosed preeclampsia), or failing to perform a timely C-section for other documented reasons. A full and thorough investigation of all the medical records will explore every potential cause of the injury.

Can a case be won if the hospital or doctor has a different interpretation of the EFM strip?

Yes. In fact, this is the central conflict in most birth injury trials. The defense will almost always have their own professionals who argue that the medical team’s interpretation and actions were reasonable. Our job is to use our own highly-credentialed medical professionals, the established NICHHD guidelines, and the facts from the EFM strip itself to demonstrate to a judge or jury that the care provided fell below the accepted standard of care and caused your child’s injury.
