About This Manual
This manual is written for clinical professionals performing pulmonary function testing.
Users must be familiar with measurements and the clinical significance of basic
spirometry products.
Before using the spirometer, all users and technicians must read and understand this
manual and all other information accompanying the CP 200 spirometry option and the
CP 200 electrocardiograph.
Caregivers need to know how to properly coach patients, to recognize acceptable
waveforms, and to know whether results meet ATS reproducibility criteria.
The hospital's Biomedical/IT support staff shall require primary skills including disciplines
related to maintenance and servicing computer controls/platforms.
It is recommended that users attend a certified spirometry training course. The
instructions given here are only a guide and should not be used to train a technician.
For definitions of specialized terms and abbreviations used in this manual, see “Glossary”
on page 77.
Note
This manual supplements the CP 200 electrocardiograph manual, entitled
CP 200 12-Lead Resting Electrocardiograph Directions for Use.
See the electrocardiograph manual for procedures that are common to both ECG
and spirometry functions, such as how to move through the menus, how to
search for patient data, or how to edit the medication list.
Directions for Use Chapter 1 Introduction 3
Product Overview
The CP 200 spirometry option performs FVC and SVC testing, including pre- and postbronchodilator testing. It displays flow/volume and volume/time curves in real time,
depicting both inspiratory and expiratory measurements.

Intended Use
The CP 200 spirometry option allows the user to acquire, view, store, and print measures
and waveforms of pulmonary function including, but not limited to, maximal volume and
flow of air that can be moved in and out of a patient's lungs. These measures are used in
the diagnosis and monitoring of lung diseases and interventions for the treatment of
certain lung diseases.
The spirometer may be used with patients who are able to understand the instructions for
performing the test. However, normal values and interpretive results are not calculated
for children under the age of six.
Indications for Use
Spirometry is indicated for use in various common clinical situations:
• Assessing health status before a patient begins strenuous physical activity.
• Evaluating the following symptoms, signs, or abnormal laboratory tests:
Symptoms — dyspnea, wheezing, orthopnea, cough, phlegm production, chest pain
Signs — diminished breath sounds, overinflation, expiratory slowing, cyanosis, chest
deformity, unexplained crackles, shortness of breath
Abnormal laboratory tests — hypoxemia, hypercapnia, polycythemia, abnormal
chest radiographs
Contraindications
The spirometer does not support the MVV effort type.

Using the Spirometer Safely
Before using or servicing the spirometer, you must read and understand the following
safety-related information.
General Warnings
The following warning statements apply to spirometer use in general. Warning
statements that apply specifically to particular procedures, such as preparing the patient
for testing, appear in the corresponding sections of the manual.
Warning statements indicate conditions or practices that could lead to illness, injury, or
death.
WARNING Do not perform spirometry tests if any of the following conditions
apply to the patient:
• hemoptysis of unknown origin (forced expiratory maneuver may aggravate the underlying condition)
• pneumothorax
• unstable cardiovascular status (forced expiratory maneuver may worsen angina or cause changes in blood
pressure)
• recent myocardial infarction
• pulmonary embolus
• thoracic, abdominal, or cerebral aneurysms (danger of rupture due to increased thoracic pressure)
• recent eye surgery (for example, cataract)
• presence of an acute disease process that might interfere with test performance (for example, nausea,
vomiting)
• recent surgery of thorax or abdomen
WARNING The spirometer captures and presents data reflecting a patient’s
physiological condition. When reviewed by a trained physician or clinician, this
data can be useful in determining a diagnosis. However, the data should not be
used as a sole means for determining a patient’s diagnosis.
WARNING To minimize chance of a misdiagnosis, it is the physician’s
responsibility to assure that spirometry tests are properly administered,
evaluated, and interpreted.
WARNING To prevent the spread of infection, do not try to clean the flow
transducers and nose clips. Discard these items after a single patient use.
WARNING Read and observe all safety information provided in the flow
transducer instructions.

A patient’s best effort is a measurement calculated from a set of efforts. To determine the
way in which best effort is calculated, choose from these options:
• Best Measurement —
Defines best effort as the single best effort in a set of efforts (best FVC-pre, best FVCpost, best SVC). This ATS-recommended method uses the effort with the highest sum
of FVC + FEV1, or the effort with the highest SVC value. (For details, see the document
noted in Reference 6 on page 76.)
• Best Composite —
Defines best effort as a composite of the highest parameter values across all selected
efforts (except FVC and FEV1, which are both selected from the highest sum of
FVC + FEV1.)

Reversibility is the percentage difference between pre-test and post-test data for FVC
testing. This measurement indicates the effect of medication on lung function. Reversibility
applies to each parameter separately.
To determine the way in which reversibility is calculated, choose from these options:
• ((Post-Pre)/Pre)*100
• (Post/Pre)*100
• ((Post-Pre)/Predictive)*100
The FEV1% formula determines the calculation method for a test’s (not an effort’s) overall
FEV1% value, which affects the automatic interpretation. The variable part of this formula
is the denominator. Both the numerator and the denominator represent best effort values.
To determine the way in which FEV1% is calculated, choose from these options:
• FVC (FEV1% = FEV1/FVC
• FIVC (FEV1% = FEV1/FIVC
• FEV6 (FEV1% = FEV1/FEV6
• Max (FVC, FIVC, SVC) (FEV1% = FEV1/FVC
Yes or no. If yes, predictive points display and print. Predictive points may be enabled with

Yes or no. If yes, a curve displays and prints along the predictive points. When the curve is
enabled, the points are automatically also enabled.

Enable Composite
Norm Values
Yes or no. If yes, any parameters that are not supported in the primary (selected) norm are
given predictive values from alternative (composite) norm sources.
If set to no, only the primary norm’s values are used, no composite values. On the screen
and in reports, any unsupported parameters appear without predictive values.

About Calibration
The American Thoracic Society recommends calibrating a spirometer every day before
testing. In addition, each time you open a new package of flow transducers, verify the lot
number on the package label. If this lot number differs from the lot number used during
the most recent calibration, you must recalibrate the spirometer before resuming testing.
There are two types of calibration:
• Single-flow calibration
One inhale/exhale cycle.
• Multiple-flow calibration
Three inhale/exhale cycles at three different rates:
3 L in 1 second (3 L/s)
3 L in 3 seconds (1 L/s)
3 L in 6 seconds (0.5 L/s)
Note
For a diagram illustrating this procedure, see Figure 9 on page 25.
For step-by-step calibration instructions, see “Performing a Calibration” on page 26.
For information on reviewing or changing the settings that affect calibration, see
“Reviewing the Calibration Settings” on page 15.
If you want to add efforts to a saved test, the calibration must stay the same.
Whenever you recalibrate, you lose the ability to add new efforts to tests that
were saved earlier.
Caution For proper performance, the calibration syringe itself must be
recalibrated every year. See its calibration certificate for the most recent
calibration date. When the syringe is due for recalibration, return it to the
manufacturer. For details, see “Service Policy” on page 53.
