FG504 1 AMP FUSE MODIFICATION
To improve reliability of the FG504 , Mod # M41569 was implemented at Serial
Number B057810 . The current one ( 1.0 ) amp . fuse ( P / N 159-0116-00 ) has
proven to be both heat sensitive and mechanically weak and will be replaced
by a one and a half ( 1.5 ) amp . fuse ( P / N 159-0153-00 ) .
To install this modification in an existing FG504 perform the following :
1
.
Remove F1616 and F1716 ( P / N 159-0116-00 ) from the A4 Floating Board .
2 .
Remove F1615 and F1715 ( P / N 159-0116-00 ) and the four associated pin
sockets ( P / N 136-0261-00 ) from the Al Main Board .
3 .
Install the new fuse ( P / N 159-0153-00 ) along with a protective sleeving
( P / N 162-0008-00 ) into the four vacated positions as shown in the
following diagram .
159-0153-00

MEDICAL
413A
QUESTIONS
AND
ANSWERS
The following information may be useful to expand your knowledge of the 413A
capabilities
:
QUESTION : WHAT IS CVA ( CARDIO VASCULAR ARTIFACT ) ?
ANSWER :
The pumping action of the heart causes a change in chest impedence
due to blood flow through the lungs . This signal is picked up by
the
respiration
circuit
and
displayed on
the
respiration
waveform
as
an
artifact
.
Q : WHAT IS THE FUNCTION OF THE CVA DETECTOR ? HOW DOES IT WORK ?
A : The function of the CVA Detector is to check for coincidence between the
ECG
signal and the
respiration
signal .
When no
inspirations
are
detected
,
the
gain of the
Inspiration
Detector
automatically
increases
.
This
allows the Inspiration Detector to sense the change in chest impedence
due to blood flow through the lungs . This impedence change is CVA , and is
rejected
by
comparing
its
timing
with
the
ECG signal
.
Q : WHY
DID YOU
CHANGE THE
NOMENCLATURE
FROM
"
RESPIRATION "
TO "
RESPIRATORY
EFFORT
" AND "
APNEA "
TO "
RESPIRATORY
EFFORT
ARREST " ?
A : In the standards set by the FDA , respiration is defined as air exchange in
the lungs . Since the 413A measures breathing effort only , true apnea ( lack
of
air exchange
)
may
not
be
detected
if
there
is an
airway
obstruction
.
The
nomenclature
emphasizes
this
distinction
.
Q : WHY
IS THE
QRS
WARNING
PRINTED
ON THE
FRONT
PANEL ?
A :
The
labeling on
the door
is a
reminder
that
CVA will
not
be
detected
unless
the
ECG channel
is
indeed
on
and
functional .
Without
the
ECG
channel
turned
on ,
CVA
could
mimic
respiratory
effort
,
and
crisis
situa
tions
could go
undetected
.
The CVA
detector
looks for
a
decrease in
chest
impedence
in a
time
" window
"
following a
QRS
detection .
When
CVA is
detected on four consecutive QRS occurrences , the inspiration detector is
inhibited ; and the inhibit is not removed until a QRS occurs without a
corresponding
CVA
.

413A QUESTIONS AND ANSWERS ( Cont . )
Q : WHAT HAPPENS WHEN I MONITOR RESPIRATION WITH THE ECG CHANNEL TURNED OFF ?
A : A respiratory effort arrest ( apnea ) condition may be ignored by the
alarms . This is because the ECG timing data , used to reject CVA , is
missing
.
The CVA may thus be mistaken for a true respiratory effort
signal
.
Q :
WHY WILL THE ALARM SOMETIMES SOUND WHEN I HAVE NO ALARMING CONDITION ?
A :
This will always happen when the pressure / pulse alarm is pushed in and
pressure /
pulse
is
not being
monitored
.
It can also happen if electrodes
are not properly applied and respiratory effort signal is inadequate .
Q :
HOW IS THE ZERO ADJUST DIFFERENT IN THE 413A ?
A :
As you know , this control permits establishment of a zero - pressure refer
ence , and is adjustable with a screwdriver or fingertip . Pressing in
while rotating the control provides a fast , accurate indication of offset
on the digital display . The 413A zero control has a course and fine
adjustment to provide good adjustment resolution over a wide range of
pressure
transducer
offset
values .
Small
adjustment
angles
provide
easy
settability
,
while
large
angles
give wide
range
.
Q : SHOULD THE 100mm TEST BE HELD IN WHILE ZEROING THE TRANSDUCER ?
A :
No
!
Zero can only be adjusted when transducer is connected and test
signal
is
inactive .
Q : HOW IS THE INTEGRITY OF THE ECG AND RESPIRATION LEADS CHECKED ?
A :
Connect the patient cable to the input connector at the back of the instru
ment , and attach the electrode wires to the branch block .
Then snap the
wires onto the side of the instrument marked " ECG RESP LEAD TEST " . These
three terminals provide a test signal for checking cable , electrode , or
electrode wire defects , and ECG / Respiratory effort circuit operation .
When the ECG lead selector button is pushed in and the ECG size and respi
ratory effort size controls are centered on the mid range mark , the display
should read : ECG Lead I = 20mm of positive going signal at 117BPM , ECG Lead
I I = 30mm of positive going signal at 117BPM , ECG Lead III = 10mm of positive
going signal at 117BPM , Respiratory Effort = 10mm tilted square - wave at 29
breath
/
min .
If LEAD FAULT indicator lights , the cable or the electrode
wires may be defective .
