CompuFlo® Epidural

Intelligence for First Attempt Epidural Placement

The CompuFlo® Epidural Instrument offers objective detection of pressure changes to verify true loss of resistance and confirm the epidural space

The New Standard

CompuFlo Instrument Uses DPS Dynamic Pressure Sensing Technology® Systems 1-4

  • Subjective tactile feel + objective DPS - differentiates between true loss and false loss of resistance
  • 25% reduction in procedure time for labor and delivery epidurals
  • Clinicians can successfully perform epidural procedures with fewer attempts
  • Detects subtle pressure changes 4 times a second, making it extremely responsive to minor pressure changes
  • Precisely controls the flow rate of fluid with real-time feedback, based on exit pressure at the needle tip
  • The CompuWave Display shows the pulsatile waveform found in the epidural space, again confirming needle and catheter placement

CompuFlo® Epidural Instrument Setup Instructions

1 step-1

Turn on the CompuFlo® instrument.

2 step-2

Take out the disposables package.

3 step-3

Unpackage the disposables.

4 step-4

Connect the pre-filled saline syringe to the pressure sensor.

5 step-5

Insert the syringe into the syringe receptacle until it is fully seated.

6 step-6

Firmly insert the ID adaptor into the ID adaptor port on the right side of the instrument.

7 step-7

Select the desired epidural needle size.

8 step-8

Approve the choices. Auto-purge starts and fills the extension tubing with fluid.
