What is FAST & eFAST Ultrasound?
The FAST exam, or Focused Assessment with Sonography for Trauma, is a rapid bedside ultrasound protocol used primarily in trauma settings to detect free fluid—most importantly blood—in the peritoneal, pericardial, and pleural spaces. Its extended version, the eFAST exam, adds the evaluation of the thorax to detect pneumothorax and hemothorax.
Both these protocols have become first-line investigations in trauma because they provide immediate, actionable information without the delays or risks of transporting unstable patients to radiology.
Traditional ultrasound machines, while effective, often suffer from limitations in trauma settings:
- Bulky size slows deployment in emergency scenarios.
- Long boot-up times delay critical assessments.
- Dependence on power outlets restricts mobility.
Handheld ultrasounds bridge this gap by offering portability, rapid startup, and battery-powered operation.A 2021 study in Current Emergency and Hospital Medicine Reports showed that handheld ultrasounds provide accuracy comparable to conventional machines for FAST exams, with the added benefit of faster scan times.
Their ability to function at the bedside, in ambulances, and even in prehospital environments makes them a critical extension of modern trauma protocols.

Key Features of an Ideal Handheld Ultrasound for FAST
When choosing a handheld device for FAST exams, these five fundamental features are non-negotiable:
- Portability and Ease of Deployment – Lightweight and compact devices allow clinicians to perform scans in tight spaces, from crowded ERs to ambulances.
- Image Quality in Emergency Conditions – High-resolution imaging ensures detection of subtle fluid collections even in difficult patient conditions.
- Speed of Use – Minimal boot-up times and intuitive interfaces are essential to avoid delays during resuscitation.
- Battery Life – Long-lasting batteries ensure uninterrupted performance during extended trauma cases or in prehospital settings.
- Connectivity – Devices that support wireless and wired options allow for quick data transfer, while ensuring seamless DICOM integration for image sharing.
Advanced Functional Features
Beyond the basics, an ideal handheld ultrasound for FAST should include advanced functions that optimize workflow and improve diagnostic accuracy in real-world trauma care.
- Preset Optimization for FAST – Preconfigured imaging settings for the three core FAST areas—abdomen, lung, and cardiac—help reduce operator dependency and scanning time. These presets automatically adjust depth, gain, and focal zones to highlight the regions most relevant for detecting free fluid.
- Probe Versatility – A phased array or curvilinear probe (2-5 MHz) is standard for FAST, but having multi-frequency options allows adaptability for different body types. Handhelds supporting all three probes are useful beyond trauma (e.g., vascular or lung ultrasound).
- Doppler Capabilities – While not always essential for FAST, color and power Doppler help differentiate fluid from vascular structures, reducing false positives. This is particularly useful in assessing pericardial effusions or distinguishing ascites from active bleeding.
- Cine Loop and Image Storage – Trauma often involves rapid decision-making with multiple team members. The ability to record clips (cine loops) and storage allows clinicians to review and share critical findings, ensuring accuracy and team-based verification.
- Reliable Built – Trauma settings demand durability as devices are exposed to drops, spills, and harsh handling. A robust design—shock-resistant, water-tolerant, and built to military-grade durability standards—ensures the device performs reliably in both hospital trauma bays and field deployments.
