cSpirometer™Sensor Instructions for Use
Cohero Health, Inc. cannot be held responsible for any damage caused
by users failing to follow the instructions contained in this manual.
1. Indications for Use
cSpirometer sensor is intended for home use by patients to monitor PEF
(Peak Expiratory Flow) and FEV1 (Forced Expiratory Volume in one second).
The device is designed for children greater than ve years of age, adolescent
and adult subjects.
2. Important Information Concerning Intended Use
PEF is the maximum speed a person can blow air out of the lungs after taking
as big a breath as possible.
FEV1 is the maximum volume of air a person can exhale from the lungs in
one second after taking as big a breath as possible.
CAUTION: WHEN CSPIROMETER SENSOR IS USED TO MONITOR LUNG
CONDITIONS SUCH AS ASTHMA YOU SHOULD BE UNDER THE CARE OF A
PHYSICIAN OR OTHER LICENSED HEALTHCARE PROFESSIONAL.
Medical studies have shown that regularly reviewing accurate measurements
of PEF and FEV1 with a physician or other licensed healthcare professional
may allow individuals with lung disease to better manage their conditions.
It is important to watch for changes from one measuring to the next, and to

follow the actions you have to take according to the action plan provided to
you by your physician or other licensed healthcare professional.
If you have breathing conditions such as asthma your physician or licensed
healthcare professional may recommend that you measure PEF/FEV1 to
watch your disease and discover if there are changes in your airow. When
you blow into the mouthpiece of the ow meter, the device will display a
number. The faster you blow, the higher the reading.
This number tells you how well air is moving through the airways in your
lungs. When you use cSpirometer sensor regularly, you will be able to detect
changes in your measurements, which will tell you and your physician or
other licensed healthcare professional what is happening with your lungs.
These changes may require special treatment of your condition according
to the action plan given to you by your physician or licensed healthcare
professional which will tell you when and how often to use your cSpirometer
sensor. They also will explain how your PEF and FEV1 measurements help
them monitor your lung function and how well treatments are working.

3. Determining Your PEF Baseline Value
A PEF measure with a high value usually means that your airow is good.
The best way to determine what is a healthy PEF for you is to discuss this
with your physician or other licensed healthcare professional. In fact the
importance of any changes in airow from one measurement to the next
depends upon how dierent they are from your baseline value when you are
in healthy physical condition.
Your physician or other licensed healthcare professional will use one of two
possible ways to identify your baseline value. The rst method adopts the
predicted value calculated according to the results of epidemiological studies
of large groups of healthy subjects of your same age, height, sex, and origin.
The second method adopts the personal best value you can reach when you
are in the healthiest physical condition.
The ATS (American Thoracic Society): PEF predicted values are calculated
according to Knudson, R. J., Slatin R. C., Lebowitz, M. D., Burrows, B., The Maximal
Expiratory Flow-Volume Curve – Normal Standards, Variability, and Eects of Age,
AM REV RESPIR DIS, 1976 113;587-600.
It is important to know that these predicted values are average numbers
for large groups of people. You may have a higher PEF measure than the
predicted value and you may not be healthy. Or you may have a lower PEF
than the average and be healthy.

your treatment plan. if you have trouble determining your baseline
value, ask your physician or other licensed healthcare professional for
assistance.

Please read all the information in this user manual before using this
device. If you do not understand these instructions or if you have
questions about your PEF and FEV1 meter and its use consult your
physician or other licensed healthcare professional.
When cSpirometer sensor is used to monitor lung conditions such as
asthma you should be under the care of a physician or other licensed
healthcare professional.
A healthcare professional’s advice is required to interpret the meaning
and importance of the measurements reported by cSpirometer sensor
and how to decide on an appropriate action plan.
Diagnosis and appropriate treatments are to be given only by a physician
or other licensed healthcare professional. The action plan will tell you
what action to take when there are changes in your measures.
Self–measurement means control, not diagnosis or treatment. In
any event please be sure to discuss your measured values with your
physician or other licensed healthcare professional. They will also
explain which values are normal for you.
No matter what your measures are, if you have signs and symptoms
such as chest tightness, shortness of breath, coughing or wheezing you
