Imprecision detection
This is one category of potential reasons that can compromise the capture precision which is detected by the PIC system in the interactive detection screen.
There are other possible reasons that can affect precision:
By understanding these additional factors, you can effectively address and rectify any issues before attempting another capture.
MORE INFORMATION: Imprecision detected
External elements touching the PIC transfers can cause micro-movements. There are three common sources of micro-movements:
Patient's tongue
During a capture, it is common for the patient's tongue to come into contact with the PIC transfers, particularly when using more than four transfers. In such instances, the recommended solution is to use cotton rolls to help stabilize the tongue.
By strategically placing cotton rolls around the tongue, it can be gently hold in a stable position, reducing the likelihood of unintended contact with the PIC transfers.
Mouth opener
For optimal visibility of all PIC transfers captured by the PIC camera, it is recommended to utilize a mouth opener such as metal retractors or an OptraGate® to adequately open the patient's mouth. The use of a mouth opener prevents the patient's lips from interfering with the PIC transfers, but it must be put in with caution to avoid any contact or displacement of the transfers within the mouth.
By doing this, the mouth can be comfortably opened wider, providing a clear line of sight for the PIC camera.
Operator's fingers
It is advised to refrain from using the operator's fingers to hold the patient's mouth open during the capture of PIC transfers (as seen in the photo to the right). Instead, it is recommended to utilize large, metal retractors or an OptraGate®.
By using a mouth opener, the risk of accidental touch or interference with the PIC transfers is minimized.
