Listing of Warnings, Cautions, and Notes
P-495220-00 Rev. D 4
CAUTION
Battery Cautions
• The NiCad battery pack or other batteries may discharge over time.
Check batteries at least once per month for corrosion and verify
batteries are fully charged. Store spirometer in base station to keep
unit ready for use.
• Remove batteries if spirometer will not be used for at least two weeks.
• Dispose of batteries properly. Do not incinerate. Puritan Bennett
recommends that customers or technical service personnel follow local
governing ordinances and recycling instructions regarding disposal or
recycling of batteries.
Service Caution
• Do not remove the cover of the Renaissance II Spirometry System or
base. Removal of the cover is permitted only by qualified service

Flow Sensor Cautions
• Use only the FSII flow sensor specifically designed for the Renaissance
II Spirometry System.
• The FSII sensor is for single-patient use only. In the interest of
environmental protection, dispose of all sensors and nose clips
properly.
Notes
Accuracy Notes
• For test accuracy, elevation must be entered.
• Verify that the displayed barometric pressure is correct. If not correct,
there will be an error in the inspired volume (FIVC) during an FVL
maneuver of approximately -1.3% for every 1,000 feet above sea
level. Refer to the System Configuration section starting on page 78
for more information. The barometric pressure displayed is based on
the initial elevation setting of the spirometer. However, the
barometric pressure may be changed and the spirometer will, from
that point on, use the new value entered.
• If you choose to obtain barometric pressure from an agency, such as
the National Weather Service, verify that the value is NOT corrected
to sea level.

Listing of Warnings, Cautions, and Notes
5P-495220-00 Rev. D
Calibration Notes
• The date of the last valid calibration check will display as part of the
spirometer's initialization sequence if a calibration check has not
been performed in the current calendar day.
• The American Thoracic Society (ATS) recommends performing a three-
speed calibration check on a daily basis.
• Puritan Bennett recommends that the 3 liter calibration syringe be
recertified on an annual basis.
• Verify that the temperature of the room is the same as the
temperature noted for the calibration test. For every degree
discrepancy, there will be a corresponding 0.15% error in the test
results.
• Overestimation of the room temperature will cause lung volume to
be underestimated by 5%; conversely, if temperature is
underestimated, lung volume will be overestimated.
Test Method Notes
• The “Val” (best value) method is recommended by the American
Thoracic Society and mandated by NIOSH/OSHA standards and should
be used for all industrial and disability testing.
• If the patient test will be submitted for Social Security Disability
(SSD) determinations, enter patient information prior to performing
the SSD calibration verification.
• Clinicians performing PFT studies should consider attending NIOSH
training seminars and refresher courses to further their skills in
spirometry testing and to stay current with industry standards.
Spirometer Use Notes
• Demonstrating the test using your FSII sensor is strongly
recommended for patients that have never performed a spirometry
test before.
• Obstructing sensor opening with teeth, lips, or tongue while
performing the test will cause low readings.

Battery Notes
• The Renaissance II base station allows interfacing to parallel printers
and computers and provides an alternate means for charging the
custom NiCad battery pack.
• The Renaissance II Spirometry System is designed to recharge only
the custom battery pack supplied with the system, and will not
recharge batteries from other manufacturers.
• When there is a low battery condition, the Renaissance II spirometer
beeps every 30 seconds and a low battery icon is displayed.
• Do not mix brands or types of batteries.
• Puritan Bennett recommends replacing the NiCad battery pack at
least once per year.
• If the battery is removed, the unit will operate solely on AC power if

Introduction to the Renaissance II Spirometry System
The Renaissance II Spirometry System consists of a spirometer, docking base
and optional accessories, as shown in Figure 2. The Renaissance II system
provides long-term data storage capacity, and when connected to a printer
generates printouts of the data. Patient data can also be downloaded to a
computer. The spirometer test results can be compared to any of several adult
or pediatric predicted normal values. The spirometer also performs pre/post
medication comparisons.
Features
• Intuitive graphical user interface.
• Graphic display for real-time viewing of Volume-Time, Flow-Volume and
incentive displays.
• Automatically compares results to predicted values.
• Allows pre/post-medication comparisons.
• Provides clinical interpretations with COPD Risk and Lung Age
calculations.

Intended Use
The intended use of the Renaissance II Spirometry System is as a diagnostic
tool to measure the maximal volume and flow of air that can be moved in and
out of a patient’s lungs. The Renaissance II spirometer obtains the spirometric
data by direct measurement of flow via the FSII sensor and pressure tube. The
flow is then electronically integrated to obtain volume. This testing can be used
for the detection, assessment and monitoring of certain lung diseases. The
system is intended for use with pediatric (4 to 17 years) and adult patients (18
to 99) in hospitals, physicians’ offices, laboratories, and occupational health
testing environments.
CAUTION:
• Place the Renaissance II Spirometry System in a secure location,
where it is unlikely to drop or fall. Do not attempt to lift or
carry the Renaissance II spirometer by the pressure tube or
power cord.

status. A low battery indicator will appear in the right hand corner of the screen
when fewer than 20 patient tests can be performed. If the battery voltage drops
below a reliable operating level, the unit will shut-off and not power-up until
the batteries are recharged, changed, or the AC adapter is connected.
Connecting the Pressure Tube
The Renaissance II spirometer is shipped
with a pressure tube that connects the FSII
flow sensor to the spirometer. Upon receipt,
inspect the pressure tube for damage. If the
tube is damaged, contact Puritan Bennett
Technical Support at 1-800-255-6774.
Connect the pressure tube to the underside
of the spirometer, as shown in Figure 3.
Connect the other end of the pressure tube
to the FSII flow sensor, as shown in
Figure 4.
NOTE: If the battery is removed, the unit will operate solely on AC power if
connected to an electrical outlet via the AC adapter.
CAUTION:
• The NiCad battery pack or other batteries may discharge over
time. At least once per month, check batteries for corrosion and
verify batteries are fully charged. Store spirometer in base
station to keep unit ready for use.
• Remove batteries if spirometer will not be used for at least two
weeks.
NOTE: Puritan Bennett recommends replacing the NiCad battery pack at least once
per year.

Spirometry Testing
Introduction to Spirometry Testing
The purpose of a spirometry test is to assess and monitor a patient’s lung
condition. The most common spirometry test is the Forced Vital Capacity
(FVC) test. This test requires the subject to take a deep breath and then exhale
into the spirometer as forcefully, rapidly and completely as possible. The FVC
test results report how fast the air was exhaled (flow rate) and how much air
was exhaled (volume). These parameters are compared to values derived
from ‘Predicted Normal Equations” based on the patient's age, height, gender
and race. These equations are listed starting on page 60. Depending on the
results, the healthcare professional will be able to determine whether the patient
is normal, or has an obstructive or a restrictive lung pattern.
Obstructive diseases are characterized by an increased resistance to air flow.
This resistance makes it more difficult to move air into and out of the lungs
rapidly. An obstructive pattern is characterized by a reduction in the volume
that can be exhaled in the first second of the FVC test (FEV1) and by a low
FEV1/FVC ratio. The most common obstructive diseases are asthma, chronic
bronchitis and emphysema. Asthma constricts the bronchial tubes but can be
controlled by drug therapy. Bronchitis also constricts the bronchial tubes but
may not respond to drug therapy. Emphysema is the slow, irreversible
destruction of the alveoli, leading to collapsed airways.
Restrictive diseases impair the movement of the lungs or the volume of air that
can be expelled by the lungs. They are characterized by a reduction in the total
volume of air that can be exhaled. The FEV1/FVC ratio remains normal or
increases. Gross obesity, lung fibrosis, neuromuscular diseases or paralysis can
cause restrictive diseases. Several occupational related diseases such as “black
lung” and “cotton dust lung” also result in a restrictive pattern.
In addition to the FVC test, the Renaissance II spirometer can perform Flow-
Volume Loop (FVL), Slow Vital Capacity (SVC), Maximal Voluntary
Ventilation (MVV), and FEV6 tests. These additional tests will sometimes
provide more information that is helpful in the diagnosis of a patient's lung
disorder.
