Intelligence for First Attempt Epidural Placement
CompuFlo offers objective detection of pressure changes to verify true loss of resistance and confirm the epidural space
Traditional subjective technique relies on surface landmarks, feedback from the needle and tactile sensation. This makes space identification difficult —particularly in patients with a high body mass index (BMI).
Researchers report 17 % of epidural placement failures are due to false loss of resistance.
CompuFlo uses real-time Dynamic Pressure Sensing® technology to detect pressure changes that are imperceptible by touch.
Visual, quantifiable pressure and fluid measurements are paired with audible feedback to allow anesthesia providers verify the epidural space has been reached with objective intelligence.
Clinically-Proven Technology
Clinical studies have found CompuFlo more effective than the current standard of care:
- 99 % EFFECTIVE in identifying the epidural space on the first attempt
- 0 DURAL PUNCTURES compared to 4 with loss of resistance for L&D epidurals
- 14 % MORE SUCCESSFUL than loss-of-resistance technique in patients with high body mass index
- 25 % REDUCTION time for labor and delivery procedures
- RELIABLE IDENTIFICATION of ligamentum flavum and epidural space
- DIFFICULT BLOCKS rescued in a single attempt
- 3 TIMES MORE SUCCESS for inexperienced operators to identify space on first attempt with CompuFlo

CompuFlo Epidural Instrument Introduction
How CompuFlo Works 
CompuFlo is enabled by innovative Dynamic Pressure Sensing® technology that monitors pressure changes at the tip of a needle and offers objective intelligence that is imperceptible by touch and traditional technique:
- A high-resolution sensor continually detects pressure and changes imperceptible by touch
- Pressure at the tip of the needle provides objective feedback
- Fluid controls the infusion; maximum pressure stops flow, a pressure drop restarts flow
- On-screen quantifiable pressure data and waveforms display for visual verification
- An audible tone changes in pitch corresponding with pressure
Entrance to the epidural space is confirmed with three indicators: tactile feel, a visual sudden drop in pressure forming a low and stable plateau that lasts for more than five seconds, and an audible decrease in pitch.
