1. Precautions
WARNING
Please read this operation manual carefully, and operate GT-105 spirometry
system properly and safely.
1. Precautions
1.1 Contraindication and prohibition
1.1.1 Precautions for use
Prepare the device for operation according to instructions in this operation manual.
Check to be sure that all the cords are connected correctly and firmly.
When the device is used with other equipment, check to be sure that they can be used safely without causing mutual
interference.
Observe the patient closely. If any abnormality is observed, proper action, which may include stopping the test,
should be taken immediately.
Do not allow the patient to touch the device directly.
When disconnecting the cords, do not apply excessive force.
Clean the accessories, cords, and flow sensor after use. Keep them in a clean environment.
A bacterial filter must be used to reduce the risk of patient cross contamination.
If any abnormality is found in the device, Turn off the power and plug off the Flow sensor cord.
In case of malfunction, mark the device with the notice, "FAILURE" or "DON'T USE". And contact our sales office, our
authorized representative, or medical dealer in your area as quickly as possible.
GT-105 should be used by trained healthcare professionals and is not intended for patient operation.
Equipments connected to Signal I/O ports, such as RS-232C and USB have to comply with IEC60601-1. If not,
IEC60950. In order to connect other equipments, use a separation transformer for the power supply, or connect it by
means of a separation device.
1.1.2 Precautions for handling
Strong electromagnetic waves in the surrounding may cause noise in the curve or malfunction. If any unexpected
malfunction occurs during operation, check the electromagnetic environment and take appropriate measures.
Examples:
1) Use of a cellular phone
・The electromagnetic wave may cause unexpected malfunction.
Turn off the power source of cellular phones and radio equipment in the room or building where electrical equipment for
medical equipment is installed.
2) When high-frequency noise generated by other equipment enters through the socket for power source
・Identify the source of noise, and take countermeasures such as installing a noise limiter in the circuit.
・If possible, stop the operation of the equipment that generates the noise.
・Connect the power cord to another power supply socket.
3) Electrostatic effect (caused by electrical discharge in the device or in the surrounding)
･Completely remove the electrostatic charge from the operator and patient.
・Humidify the room.
4) Effect of thunderbolt
・An excessive voltage may be induced in the device when a thunderbolt occurs in the neighborhood. In such a case, operate
the device using an uninterrupted power supply.

-5- Rev.1.4
5) Noise generation
・If noise is caused to a receiver of radio or television by the device, move the receiver to a distant place from the device.
1.1.3 Precautions for installation
Avoid placing the device in the following places.
1) A place likely to be splashed with water.
2) A place with the direct sun light, high temperature, high humidity, dust, and air containing salt or sulfur.
3) A place with inclination, vibration, or shock (same during transportation.)
4) A place where chemical substances are stored or gasses are generated.
1.1.4 Precautions for maintenance and inspection
Do not make any modifications to the devices; any modifications made will void the warranty.
Do not disassemble the device, anytime.
Perform routine maintenance and inspection on the device.

2. Introduction
Thank you for purchasing the CardioTech, GT-105. GT-105 provides you SVC, FVC, MVV, MV,
and bronchodilator inhalation & broncho-constrictor challenge tests. Patient data can be
saved in the internal memory, also be downloaded to a computer for database creation and A4
printing with optional Spirobank software. It also provides the useful information to help
physicians to diagnose patients’lung function as well as COPD. GT-105 features the large full
color LCD, high-speed in-line thermal printer, highly accurate pneumotacho flow sensor, and
RS-232C/USB interfaces for data transfer. GT-105 is suitable in early detection of respiratory
impairments such as Asthma and COPD. We trust our product will enable you to use
office-based Spirometry tests to diagnose and enhance your patient’s pulmonary health.
Caution: Federal (U.S.A.) restricts this device to sale by or on the order of a physician.
Spirometry testing
Spirometry is used to measure the rate at which the lung changes volume during forced
breathing maneuvers. The most commonly performed test procedure uses the forced
expiratory vital capacity (FVC) maneuver, in which the subject inhales maximally and then
exhales as rapidly and completely as possible. The FVC test is the most important. Generally,
it provides most of the information that is to be obtained from pulmonary function testing.
(“Interpretation of Pulmonary Function Tests”by Robert Hyatt et al) The FVC test shows how fast he
can blow (flow) and how much he can blow (volume). These parameters are compared to
normal values derived from “Predicted formula”based upon the patient’s age, height and sex.
Depending on the results, it is decided whether the patient is normal, or has an obstructive or
a restrictive lung disease.
Scope of this manual
This manual will show you how to use the CardioTech, GT-105 Spirometry system. Read and
understand the entire manual before trying to use this device.
Intended use
CardioTech, GT-105 Spirometry system is an electrical medical device designed to perform
pulmonary function tests. It is to be used by physicians or by trained personnel on a
physician’s responsibility. It is intended for use with pediatric and adult patients in hospitals,
physicians’ offices, and occupational health testing environments.
Indications for use
The CardioTech Spirometry System, Model GT-105 is 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 system
is intended for use with pediatric (4 to 17 years) and adult (18 to 99 years) patients in
hospitals, physician’s offices, laboratories, and occupational health environments.

4. System Preparation
Make sure that the power switch of GT-105 is OFF before attaching the power cord, flow sensor, and
other optional device, such as mouse, RS-232C, and USB cables. .
WARNING
Be sure to connect the power cord to the right voltage power outlet.
1. Connecting the Power cord
1) Connect the attached power cord to the power supply inlet located in the rear of the body.
2) Connect the other end of the cord to 100-120V or 220-240VAC, 50/60Hz power supply.
2. Connecting the Flow sensor spiral tube
1) Attach the coupler of the sensor tube “A”to the sensor tube connection port “A” on the unit.
2) Attach the coupler of the sensor tube “B”to the sensor tube connection port “B”on the unit.
Sensor tube Coupler Sensor tube connection port
3) Turn and secure the couplers as drawn.
