What is a phrenic pacemaker?
Phrenic Pacemaker
- Definition
- The phrenic pacemaker is an implantable
diaphragmatic phrenic nerve stimulator that
provides support for patients with chronic
ventilatory insufficiency whose diaphragm,
lungs, and phrenic nerves have residual function
(Aron, 2005). - Indications
- Potential candidates for a phrenic pacemaker
include but are not limited to those individuals
who require chronic ventilatory support related
to - Central alveolar hypoventilation
- Decreased day or night ventilatory drive (i.e.,
sleep apnea, Ondines Curse) - Brain stem injury or disease
- Spinal cord injury or disease
-
- Mr. M. is a 57 year old male veteran who was
critically injured in a motor vehicle accident in
1984. The accident rendered him a C-2
quadriplegic who became dependent on a mechanical
ventilator to breathe. In 1985, Mr. M. had a
phrenic pacemaker implanted. The phrenic
pacemaker took the place of the mechanical
ventilator. Mr. M. has been phrenically paced
for almost twenty years. He attributes an
increased quality of life benefit directly to the
phrenic pacemaker. Mr. M. states that the
phrenic pacemaker is 100 natural compared to
being on a ventilator. - Mr. L. is 42 year old male veteran who was
rendered a C2 quadriplegic from a motor cycle
accident. Since his respiratory muscles lost
their ability to function, Mr. L. relied on a
mechanical ventilator to breathe until he had a
phrenic pacemaker placed in 1985. This was
almost twenty years ago. Mr. L. reports that
it really feels like I am breathing on my own
with the phrenic pacemaker.

Phrenic Pacemaker System Components
- External radio transmitter with a 9-volt battery
or batteries - External antennae
- Radio receivers implanted into subcutaneous
pockets - Electrodes sutured to the phrenic nerves
- The external radio transmitter transmits energy
or an electrical stimulus through the two
antennae that are taped to the persons skin.
The signal is then received by the radio
receivers implanted in the subcutaneous pockets
under the skin. The electrical pulses are then
delivered by the platinum electrodes which are
sutured to the phrenic nerves. The diaphragm
muscle contracts and inhalation occurs. The
transmitter then stops producing a stimulus,
which causes the diaphragm to relax and
exhalation occurs. The signals are automatically
repeated by the transmitter. These bursts of
pulses are applied for 1.6 seconds and repeated
12 times per minute. As a result, a normal
breathing pattern is produced.
Advantages Disadvantages
Avery Biomedical Devices, Inc.
- Advantages
Potential Disadvantages - -Improved venous return due to negative
-Battery exhaustion - not positive pressure
- -External components are small and silent
-Wire breakage from the 9-volt -
battery to the
portable transmitter - -Provides safe pacing 24 hours per day
- Breakage of the antenna wire - -Cost effective related to the ventilator
- Breakage of the electrode wires - disposables being eliminated
- -FDA approved and reimbursed by many -
Temporary loss of pacing - insurance carriers
- -Increased mobility and independence
- Infection - -Improved quality of life
- Dehiscence

- NURSING SERVICE PROCEDURE NO. 118-P-02
- SUBJECT Phrenic Pacers Skin Care of the
Individual With - PURPOSE To outline the care of individuals with
phrenic pacers, i.e., care of - skin under pacer.
- DEFINITION The diaphragm pacing system is an
implantable diaphragmatic/ - phrenic nerve stimulator that provides support
for individuals with chronic - ventilatory insufficiency whose phrenic nerves
are intact. - SPECIAL CONSIDERATIONS
- Ambu bag must be available at all times.
- Respiratory Therapy is responsible for the
changing of the antenna with - Nursing assistance, if required.
- Antenna must be changed every 6 months and PRN
(cracked antenna, loosened - connections, patient complaining of difficulty
breathing) - Tegaderm must be changed monthly and PRN
(dislodged, loss of contact with - skin)
- Transmitter do not allow to become wet, do not
drop, protect during
ESSENTIAL STEPS IN PROCEDURE KEY POINTS 1.
Explain procedure to patient.
1. Decrease patient anxiety 2. Wash
hands.
2. Handwashing is considered
the single
most important
procedure in preventing cross-
contamination. 3.
Put on gloves.
3. Standard precautions. 4.
Following patient inspiration, gently
4. Changing one antenna at a lift
off right antenna including both
time allows the patient to layers of
Tegaderm, wash and dry
continue breathing with skin, removing any
remaining the
other pacer. adhesive. 5. Place on
layer of Tegaderm followed 5.
Antenna should be positioned by antenna
over the implanted receiver. and
repositioned until contact
provides maximum operation
efficiency
(breathing).
Antenna must lie flat. 6. Cover antenna
with second layer of Tegaderm. Apply
hypoallergenic tape if necessary. 7.
Repeat steps 3, 4, 5, and 6 for the left
antenna. 8. Ambu patient and notify
Respiratory Therapy immediately if patient
experiences respiratory distress. 9.

Helpful Hints
- If the phrenic pacemaker malfunctions, adequate
ventilatory support must be maintained or - the person will arrest.
- Ensure pulse oximetry and apnea monitor are
available. Document refusal. - A back- up ventilator is warranted. The person
with a phrenic pacemaker can also be - taught to perform glossopharyngeal (frog)
breathing to provide emergency respiration. - Turn off the phrenic pacemaker during prolonged
manual and/or mechanical ventilation. - Transtelephonic monitors relay data from the
phrenic pacemaker if a problem is suspected. - MRI and shock wave lithotripsy are
contraindicated. - Avoid exposure of the implanted components to
therapeutic levels of ultrasound energy. - Nurses should review the hospital policy and the
phrenic pacemaker instruction manual when - caring for a spinal cord injured individual with
a phrenic pacemaker.
