Quick answer: The correct term is performing when referring to the act of carrying out a Cardiotocography (CTG) procedure. “Assisting” is not a standard alternative spelling or synonym for the primary action; it denotes a supportive role. If you are the clinician operating the monitor, you are performing a CTG.
It is surprisingly common to see confusion between the terms “performing” and “assisting” in medical documentation, particularly among junior staff or students new to obstetric wards. This confusion often stems not from a spelling error in the traditional sense—like “gray” versus “grey”—but from a misunderstanding of clinical roles and verb precision. In high-stakes healthcare environments, precise language is not just a stylistic preference; it is a legal and safety necessity. When documenting patient care, stating that you were “assisting” with a CTG when you actually “performed” it can misrepresent your level of responsibility and clinical involvement. Conversely, claiming you “performed” a complex interpretation when you only helped position the patient is equally problematic. Understanding the distinct semantic boundaries of these two words ensures accurate medical records and clear professional communication.
| Term | Meaning / When to use | Example sentence |
|---|---|---|
| Performing | Actively carrying out the procedure, including placing transducers, interpreting traces, and making clinical decisions. | “The midwife was performing a CTG to monitor fetal heart rate during labor.” |
| Assisting | Providing support to the primary clinician, such as helping with patient positioning or fetching equipment, without leading the procedure. | “The student nurse was assisting the registrar by holding the ultrasound probe during the CTG setup.” |
When to use Performing
Use the word performing when you are the primary agent executing the clinical task. In the context of Cardiotocography (CTG), this involves the physical application of the monitoring devices, the adjustment of the signal quality, and the ongoing assessment of the fetal heart rate and uterine contractions. It implies ownership of the procedure.
From a linguistic standpoint, “performing” is the gerund form of the verb “to perform,” which means to carry out, accomplish, or fulfill an action. In medical jurisprudence, the person who performs a test is often the one held accountable for its accuracy and the subsequent clinical actions taken based on its results. Therefore, if you are the one who walked into the room, applied the gel, secured the belts, and initiated the monitoring session, you are performing the CTG.
Consider these real-world scenarios where “performing” is the only correct choice:
- In a Shift Handover Email: “I spent the last hour performing continuous CTG monitoring on Patient A due to decreased fetal movements; the trace is currently reactive.”
- On a Resume or CV: “Competent in performing and interpreting antenatal and intrapartum CTGs in high-risk obstetric settings.”
- In a Clinical Note: “Dr. Smith arrived at 14:00 and began performing a CTG to assess fetal well-being following maternal fever.”
The key indicator here is agency. You are doing the work. The action originates with you and is completed by you. Even if a colleague is present in the room, if they are merely observing or waiting for their turn, you are still the one performing the task at that moment. This distinction is vital for billing codes, legal protection, and professional portfolio building. As noted in general definitions of the term, performing involves the execution of an action or function, which aligns perfectly with the active clinical duty of managing a CTG machine.
When to use Assisting
Use the word assisting when your role is supportive rather than primary. This term defines a secondary position in the clinical hierarchy of the specific task. You are helping someone else who is performing the procedure. This might involve physical tasks that facilitate the main action, but you are not making the critical clinical decisions regarding the setup or interpretation.
“Assisting” comes from the Latin assistere, meaning to stand by. In a medical context, it implies presence and aid, but not primary responsibility. If you are holding the patient’s hand, adjusting the bed height so the lead clinician can reach the abdomen, or printing the trace for the doctor to review, you are assisting. You are not the operator of record.
Here are examples where “assisting” is the appropriate terminology:
- In a Student Logbook: “Today I focused on assisting senior midwives with CTG setups, learning how to optimize signal acquisition while ensuring patient comfort.”
- In a Team Debrief: “While Nurse Jones was performing the emergency CTG, I was assisting by preparing the resuscitation trolley in case the trace showed severe bradycardia.”
- In a Job Description: “The role involves assisting consultants during complex deliveries, which may include setting up CTG monitors under supervision.”
The nuance here is crucial for trainees. Many nursing students or junior doctors feel pressure to claim they “performed” procedures to bolster their experience logs. However, honesty in using “assisting” demonstrates professional integrity and a clear understanding of scope of practice. It shows you know the difference between watching/helping and doing. If you claim you performed a procedure when you only assisted, you risk being asked detailed technical questions during an interview or appraisal that you cannot answer, damaging your credibility.
How to remember the difference
The most effective way to remember the difference between performing and assisting in the context of CTG (or any medical procedure) is to use the “Pen Test.”
Ask yourself: “Who holds the pen?”
- If you are the one who will sign the medical notes, take legal responsibility for the interpretation, and make the call to escalate care based on the trace, you are performing. You own the outcome.
- If you are handing the pen to someone else, or if someone else is signing the notes while you stand by, you are assisting. You support the outcome, but you do not own it.
Another helpful mnemonic is the “P” for Primary rule.
- Performing = Primary actor.
- Assisting = Auxiliary support.
This mental shortcut works because it bypasses the complex clinical details and focuses on responsibility. In my years editing medical portfolios, I have seen countless candidates write “Assisted in performing CTGs” when they actually did them alone, underselling their skills. Conversely, I have seen others write “Performed CTGs” when they merely watched, which is a dangerous overstatement. Use the Pen Test to keep your language honest and accurate.

Common mistakes and exceptions
One of the most frequent errors I encounter is the phrase “helping to perform.” While grammatically acceptable in casual conversation, it is weak and ambiguous in professional writing. It blurs the line between assisting and performing. Instead, choose one: either you assisted, or you performed. Avoid hedging.
US vs. UK Spelling Note: While the core confusion here is semantic, there is a minor orthographic point regarding the word “program” vs. “programme” if you are discussing the CTG training module. In the US, you might enroll in a “CTG training program.” In the UK, Australia, and New Zealand, it is often a “CTG training programme.” However, the words “performing” and “assisting” are spelled identically in both variants of English. Do not let regional spelling differences distract you from the semantic precision required for these verbs.
The “Supervised Performance” Exception: There is a gray area known as “supervised performance.” This occurs when a trainee is physically doing the task (placing probes, adjusting gains) but a senior clinician is standing right next to them, directing every move. In this case, the trainee is technically performing the physical actions, but the senior clinician retains clinical responsibility.
How should you document this?
- For learning logs: “Performed CTG under direct supervision.”
- For legal/clinical notes: The supervising clinician usually documents the event as them overseeing the care, while the trainee notes their participation. It is rarely accurate for the trainee to say they “performed” it independently, nor is it accurate to say they only “assisted” if they did the hands-on work. The phrase “under supervision” is the critical modifier here.
Another common mistake is using “monitoring” as a synonym for both. “Monitoring” is the continuous process; “performing a CTG” is the specific act of initiating and managing that monitoring. You can monitor a patient without performing a new CTG setup (e.g., observing an existing trace). Be precise.
Frequently Asked Questions
Can I say I performed a CTG if I only placed the straps but didn’t interpret the trace? No. If you did not engage with the interpretation or clinical management of the trace, you assisted with the setup. Performing implies a holistic engagement with the procedure, including interpretation.
Is “doing a CTG” acceptable in formal medical documentation? No. “Doing” is too colloquial for professional records. Always use “performing,” “conducting,” or “initiating” to maintain professional standards and clarity.
What is the difference between assisting a CTG and observing a CTG? Assisting involves active physical help (e.g., positioning the patient, holding equipment). Observing is passive; you are watching to learn but providing no physical aid. Neither counts as performing.
Does assisting with a CTG count toward clinical competency hours? It depends on your institution’s policy. Generally, assisting counts toward exposure and familiarity, but only performing (often under supervision initially) counts toward independent competency sign-off. Check your specific curriculum guidelines.
