3.4 Sherlock 3CG™ TCS Audio Information
When the audio is on, there are four possible tones:
- Tone 1: The stylet tip is detected and the tip is not under the sensor.
- Tone 2: The stylet tip is under the sensor and is at or above the Bard logo.
- Tone 3: The stylet is under the sensor and below the Bard logo.
- Tone 4: The stylet is past max P-wave location.
Note: Tone 1 – Tone 3 audio signals are only applicable to the magnetic navigation capability of the device. Tone 4 is applicable to ECG in patients
where there are no alterations to the cardiac rhythm that change the presentation of the P-wave.
3.5 Parallax
When a patient's chest is not flat, the sensor will rest at an angle, causing an effect known as parallax. Parallax is the difference in the apparent location
of an object from two different points of view. The difference between the point of view of the sensor and the user can be several centimeters.
Note: Parallax should only be considered in relation to magnetic navigation.
