What should you know about point of care ultrasound in critical care?

Critically ill patients may not be able to travel easily for imaging. A trained clinician can bring a portable ultrasound system to the bedside and repeat focused assessments when the patient’s condition changes. Depending on the question, the scan may look at the heart, lungs, blood vessels, abdominal fluid or a procedure site. Images need to be interpreted alongside blood pressure, breathing, examination findings and laboratory results. It is not a complete substitute for formal imaging when that is needed.

If you are able to participate, tell the team about new symptoms, previous heart or lung conditions, medicines and recent procedures. Ask what the scan is checking and whether it will alter treatment. Families can ask who is interpreting the images and what further testing may be required. For a broader explanation, see Point-of-Care Ultrasound. Some image-guided procedures, including PRP Injection in other settings, use ultrasound for targeted placement.

In a critical-care setting, tell staff immediately about worsening breathlessness, chest discomfort, confusion, faintness, new weakness, severe pain or bleeding around a procedure site. Outside hospital, call emergency services for these symptoms or for a person who is difficult to wake. A scan supports urgent care decisions but should never delay airway, breathing or circulation treatment.

Ask what clinical question prompted the scan, whether it is being repeated, what the images show in relation to the examination and what decision follows. If a procedure is guided by ultrasound, ask how the team checks the target and monitors you afterward.
