Learn the guidelines for using the EpiFaith CV product effectively

Dear users,

Learn the guidelines for using the EpiFaith CV product effectively:

1. Needle Compatibility Use 18G needles. Use guidewires with a diameter of 0.64 to 0.96 mm. Different needles can affect pressure readings.

The use of alternative needles may impact pressure readings due to differences in needle tube resistance.

2. Angiocath Usage When using an Angiocath, insert it before reconnecting the EpiFaith CV to maintain pressure accuracy.

3. Auto-Aspirating Function A small volume of blood suctioned won't cause a vessel collapse.

4. Guidewire Insertion Insert the guidewire only when blood is smoothly aspirated. If the backflow is absent or small, adjust the needle first.

5. High Venous Pressure Patients The device signals high venous pressure (>30 mmHg) with a protruding insertion hole.

6. Trigger Area Interaction You can press the trigger area again to generate negative pressure, but avoid pressing continuously.

7. Guidewire Challenges If guidewire insertion isn't smooth, adjust the needle position before trying again.

8. Guidewire Insertion Hole Protrusion The device allows guidewire insertion at physicians' discretion if the hole is protruding.

9. Device Usage EpiFaith CV offers three auto-aspirations before it needs clearing of blood. Multiple uses can affect functionality due to clotting.

Note: While pressing the trigger, ensure the stability of the needle by maintaining an optimal hand posture. See the suggested gripping method for reference. It isn't mandatory to visually observe backflow. The plunger's movement, felt by touch, confirms the same.
