Pre-Surgical Eval

100

These 2 positions used for the pre-surgical evaluation

Sitting and lying on the left side

200

This is the minimum R-wave amplitude required for the AspireSR device to sense heart rate.

0.4mV

300

This machine is used to perform the pre-surgical evaluation

ECG/EKG

400

This is the placement for the RA electrode

left neck/lead implant position

500

This is the heartbeat detection sensitivity that corresponds with 0.86-1.25mV amplitude range.

Warnings and Cautions

100

The potential cardiac conditions that can occur during diagnostic testing in the OR

bradycardia and asystole

200

This is the suture color that denotes the positive electrode

white

300

This is the period of time the device should remain off following implant.

14 days

400

The sterilization indicator should be this shade to indicate the device was sterilized before shipping

gold to bronze

500

This surgical equipment should not be used once the generator is introduced in to the sterile field

electrocautery/Bovie

Diagnostics

100

This diagnostic test must be performed during the procedure to confirm the generator and lead are properly connected.

System Diagnostics

200

In a typical case, System Diagnostics is performed twice - under these conditions

outside and inside the pocket

300

This must be verified in the OR during initial implant of the AspireSR

heartbeat detection

400

High impedance in the OR is generally noted by an impedance value in this range

5300 - 10,000 ohms

500

This indicates a short circuit or low impedance

Impedance value < 600 ohms

Troubleshooting

100

The most common reason for high impedance during a NEW implant in the OR

Lead pin not fully inserted into the generator

200

On a dual pin lead, the positive lead pin is denoted by these two indicators

White marker band and Model/SN

300

This must be used when performing Generator Diagnostics

Test resistor

400

Failure to communicate with a new generator outside of the sterile field prior to the case likely indicates this

communication/programmer system error

500

Besides lead/pin connector issues, another cause for high impedance in a NEW implant case could be this

electrodes off the nerve

Potpourri

100

The one item needed during diagnostic testing in surgery NOT provided by LivaNova

a laser arm drape/probe cover/video camera bag

200

This part of the strain relief should be 3cm in circumference and secured parallel to the anchor tether

strain relief bend

300

This is the recommended direction for tunneling

Neck to chest

400

This is the position that the patient should be placed in for surgery

supine/lying on the back

500

The vagus nerve typically is positioned in a posterior groove behind these two vessels

the carotid artery and the jugular vein
