From roadside assessment to critical decisions.

POCUS designed for EMS environments.

eFAST

Rule out life-threatening injuries in seconds. With Butterfly's Ultrasound-on-Chip technology, clinicians can complete an eFAST assessment using a single handheld probe, reducing delays when every second matters. Customisable probe controls and one-touch image capture help clinicians stay focused on patient care while securely storing scans to the Butterfly Cloud.

  • Rapid abdominal assessment
  • Lung evaluation
  • Cardiac windows
  • Streamlined documentation
Lung

Unlock the power of lung ultrasound. Automatically detect and quantify B-lines within seconds, supporting rapid evaluation of pulmonary edema and fluid status during prehospital and emergency care assessments.

Vascular access

Improve guidance for challenging PIV access. As many as 1 in 2 acute care patients have difficult PIV access1. With Needle Viz™ technology and the world's first POCUS Biplane Imaging™, Butterfly iQ3 can help support successful insertion.

Frequently Asked Questions

    How is ultrasound used in EMS?

    Prehospital crews use point-of-care ultrasound to assess trauma, breathing difficulty, and circulation at the scene — informing triage and transport decisions before arrival at hospital.

    What is prehospital point-of-care ultrasound?

    It is ultrasound performed at the patient's side — in the field or in the rig — to answer focused clinical questions quickly, rather than in a hospital imaging suite.

    Why use handheld ultrasound in the field?

    A single handheld probe is rugged, pocket-sized, and boots in seconds — well suited to the space, time, and mobility constraints of prehospital care.

    Can ultrasound improve trauma triage in EMS?

    Focused exams such as eFAST can help identify life-threatening findings early, supporting faster and better-informed triage and transport decisions.

    What is eFAST and can Butterfly be used for it?

    eFAST is a focused exam for free fluid and pneumothorax in trauma. Butterfly's single-probe workflows support abdominal, lung, and cardiac windows for eFAST assessment.

    Can Butterfly ultrasound help with difficult IV access?

    Needle Viz™ and POCUS Biplane Imaging™ are designed to improve visualisation during peripheral vascular access, helping support successful insertion.
