Nursing care
Echocardiogram: the nurse's role, start to finish
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Echocardiogram nursing management centres on preparing the patient for a painless ultrasound of the heart, positioning them left lateral for image quality, and interpreting the ejection fraction once results return. An EF below 40 confirms systolic heart failure, but a normal EF does not rule heart failure out. Nursing care is otherwise low-risk: no fasting, no sedation, no recovery period for a standard transthoracic study.
What the procedure achieves
An echocardiogram uses ultrasound to show the heart's chambers, valves and wall motion in real time. It measures ejection fraction, the percentage of blood the left ventricle pumps out with each contraction, along with valve competence, chamber size and any pericardial fluid.
Ejection fraction is the figure nurses act on. A normal range sits between 55 and 70 percent. Below 40 confirms systolic heart failure with reduced ejection fraction. But a normal or preserved EF does not exclude heart failure — diastolic dysfunction, where the ventricle fills poorly despite pumping well, produces heart failure with a preserved EF. Do not read a normal EF on the chart and assume the patient's heart failure workup is closed.
Transthoracic echo (TTE) is the standard, non-invasive version done through the chest wall. Transoesophageal echo (TEE) passes a probe down the oesophagus for clearer images of the posterior heart and valves, and carries the risks of a scoped procedure with sedation.
Pre-procedure nursing responsibilities
Confirm which type of echo is ordered. A standard TTE needs no fasting, no sedation and no consent form beyond routine department policy. A TEE requires informed consent, fasting for 6 to 8 hours, and screening for swallowing difficulty or oesophageal disease.
Explain the procedure in plain terms: a technician will apply gel and move a probe across the chest, the room may be dimmed, and the patient may be asked to breathe differently or roll onto their left side. Reassure them it does not use radiation and is not painful, though the probe pressure can feel firm over the ribs.
For a TEE, verify a driver is arranged for discharge and remove dentures before sedation. For a stress echo, confirm beta-blockers or other rate-limiting drugs have been held per the ordering physician's instructions, since these blunt the heart rate response the test depends on.
Equipment and positioning
Position the patient in the left lateral decubitus position for a standard TTE. This shifts the heart closer to the chest wall and improves the acoustic window, giving the sonographer clearer views of the left ventricle and mitral valve.
The bed or exam table needs ECG leads attached throughout, since the machine correlates images with the cardiac cycle. Expose the chest from the sternal notch to below the ribcage and have towels ready for the ultrasound gel afterward.
For a TEE, position the patient in the left lateral position as for an upper endoscopy, with suction and airway equipment at the bedside. A bite block protects the probe and the patient's teeth once sedation takes effect.
Complications and early signs
A standard TTE carries essentially no procedural risk; the main nursing concern is comfort and positioning, particularly for a patient who cannot tolerate lying flat or on their left side, such as one with severe orthopnoea.
A TEE carries the risks of any sedated, scoped procedure: aspiration, oesophageal perforation, and respiratory depression from sedation. Watch for oxygen desaturation, a drop in level of consciousness, or new throat or chest pain during and immediately after the probe passes.
A stress echo, whether exercise or pharmacological, can provoke chest pain, arrhythmia or a significant blood pressure drop. Stop the test and notify the physician immediately for ST changes on the monitor, sustained tachyarrhythmia, or a systolic pressure fall of 10 mmHg or more with signs of ischaemia.
Post-procedure care
After a TTE, there is no recovery period. Wipe residual gel from the chest, help the patient dress, and they may resume normal activity immediately.
After a TEE, keep the patient nil by mouth until the gag reflex fully returns, typically one to two hours, to prevent aspiration. Monitor vital signs and oxygen saturation per your sedation protocol until the patient meets discharge criteria.
Once results are available, review the ejection fraction and any new valve or wall motion findings against the patient's presenting symptoms. A newly reduced EF in a patient admitted for dyspnoea supports a heart failure diagnosis and should prompt review of diuretic and ACE inhibitor or ARNI therapy with the team.
What to teach before discharge
Tell the patient the test is a picture of the heart's structure and pumping strength, not a stress test of exertion capacity unless a stress echo was specifically ordered. Clarify who will discuss results and when, since the sonographer performing the study will not interpret it on the spot.
For a TEE patient, teach that a mild sore throat is expected and resolves within a day or two; persistent difficulty swallowing, chest pain or fever after discharge warrants an urgent call.
If the echo confirms reduced ejection fraction, use the result as a teaching anchor. Explain that EF is one measure among several, that a normal EF on a future echo does not mean heart failure has resolved if diastolic function remains abnormal, and that symptom tracking — weight, swelling, breathlessness — matters as much as the number on the report.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our cardiovascular practice questions are the closest set to what this page covers.
Common questions
What ejection fraction is considered heart failure?
An ejection fraction below 40 percent defines heart failure with reduced ejection fraction. Between 40 and 49 is considered mildly reduced. A normal EF, 55 to 70 percent, does not rule out heart failure, since heart failure with preserved ejection fraction involves a stiff ventricle that fills poorly despite normal pump strength.
Does a patient need to fast before an echocardiogram?
No fasting is needed before a standard transthoracic echocardiogram. A transoesophageal echo requires fasting for 6 to 8 hours because it involves sedation and a scope passed down the oesophagus.
Why is the patient positioned on their left side for an echo?
The left lateral decubitus position brings the heart closer to the chest wall, improving the ultrasound's acoustic window onto the left ventricle and mitral valve. This produces clearer images than a supine position.
What is a common NCLEX question about echocardiogram nursing care?
NCLEX questions often test whether a normal ejection fraction excludes heart failure — it does not, because of HFpEF. They also test TEE-specific safety: fasting status, gag reflex return before oral intake, and sedation monitoring.
What should a nurse do if a patient develops chest pain during a stress echocardiogram?
Stop the test immediately, keep the patient on the monitor, and notify the physician. Document the vital signs, ECG changes and symptom onset time, since this determines whether the study is read as positive for ischaemia.
