Introduction Warnings, Precautions and Notes
vi 0070-00-0420 Passport 5-Lead, 5L, LT, XG Service Manual
WARNING: Do not use the following 3-Lead ECG cables with Passport 5L
(P/N, 0998-00-0126-xx) and 5L-CE (P/N, 0998-00-0131-
xx): 0012-00-0620-05, -06, -07, -08; 0012-00-0722-05, -
06, -07, -08; 0012-00-0723-05, -06, -07, -08; 0012-00-
0724-05, -06, -07, -08. The above 3-Lead cables contain a
jumper wire which connects RL (right leg) to LL (left leg). As a
result, when you view aVR, aVL and aVF you will see the
appropriate ECG waveforms (even though you are using a
3-lead cable). However, there may be excessive noise on
these waveforms which can corrupt the heart rate
calculation. See Section 5 in the Operating Instructions for a
list of the proper ECG cables.
WARNING: When equipped with Nellcor® SpO
2
, use only Nellcor®
oxygen transducers including Nellcor® OXISENSOR™
patient dedicated adhesive sensors. Use of other oxygen
transducers may cause improper oximeter performance.
WARNING: Tissue damage or inaccurate measurements may be caused
by incorrect sensor application or use, such as wrapping it
too tightly, applying supplemental tape, failing to inspect
the sensor site periodically, or failing to position it
appropriately. Carefully read the sensor directions for use,
the Passport operating instructions, and all precautionary
information before use.
WARNING: Excessive ambient light may cause inaccurate
measurements. Cover the sensor site with opaque material.
WARNING: Inaccurate measurements may be caused by incorrect
sensor application or use; significant levels of dysfunctional
hemoglobins, (e.g., carboxyhemoglobin or methemoglobin);
or intra-vascular dyes such as indocyanine green methylene
blue; exposure to excessive illumination, such as surgical
lamps (especially ones with a xenon light source), bilirubin
lamps, fluorescent lights, infrared heating lamps, or direct
sunlight; excessive patient movement; venous pulsations;
electro-surgical interference; and placement of a sensor on
an extremity that has a blood pressure cuff, arterial
catheter, or intra-vascular line.
WARNING: In certain situations in which perfusion and signal strength
are low, such as in patients with thick or pigmented skin,
inaccurately low SpO
2
readings will result. Verification of
oxygenation should be made, especially in preterm infants
and patients with chronic lung disease, before instituting
any therapy or intervention.
WARNING: Insure that the conductive parts of ECG electrodes do not
contact other conductive parts including earth ground.
WARNING: Many patients suffer from poor peripheral perfusion due to
hypothermia, hypovolemia, severe vasoconstriction,
reduced cardiac output, etc. These symptoms may cause a
loss in vital sign readings.
