(see Figure 4.18).
Therapist Trigger Mode must remain On to use On-Demand Mode for therapy (see
Section 5.1: On-Demand Mode Menu) and to initiate a therapy session and trigger
stimulation per the VNS Pairing Therapy menu (see Section 5.1.1: On-Demand Mode
Therapy via the VNS Pairing Therapy Menu). The status of the Therapist Trigger
Mode is reflected in the On-Demand Mode menu (see Section 5.1: On-Demand Mode

4.5 Impedance
In the Impedance portion of the Patient Information area of the Program Implant menu, the
Lead impedance can be checked by selecting the Check or Lead Impedance buttons (circled
in Figure 4.20). Doing so delivers a small current through the Lead to calculate the Lead
impedance. This measurement pulse contains minimal charge and is not expected to cause any
discomfort, even in the most sensitive patient. The Lead Impedance button is available at all
times once the user is logged in. See Section 3: Using the Software (SAPS).
