Important notices
Intended use
microQuark 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 responsibility.
Caution: Federal law restricts this device to sale by or on the order of a physician.
This equipment has been conceived with the aim of providing an auxiliary instrument allowing:
the formulation of lung pathology diagnosis;
important studies concerning human physiology;
the collection of important information in sport medicine.
No responsibility attaches COSMED Srl for any accident happened after a wrong use of the device, such as:
use by non qualified people;
non respect of the device intended use;
non respect of the hereunder reported precautions and
instructions.
Warnings
The device, the program algorithms and the presentation of measured data have been developed according to the specifications of ATS (American Thoracic Society) and ERS (European Respiratory Society). Other international references have been followed when these were not available. All bibliography references are reported in Appendix.
The present handbook has been developed with respect of the European Medical Device Directive requirements which sort microQuark within Class II a.
It is recommended to read carefully the following precautions before putting the device into operation.
The precautions reported below are of fundamental importance to assure the safety of all COSMED equipment users.
1. This user manual is to be considered as a part of the medical device and should always be kept on hand.
2. Safety, measure accuracy and precision can be assured only:
8 - microQuark User Manual
using the accessories described in the manual or given with the device. Actually non recommended accessories can affect safety unfavourable. Before using non recommended accessories it is necessary to get in touch with the manufacturer;
ordinary equipment maintenance, inspections, disinfection and cleaning are performed in the way and with the frequency described;
any modification or fixing is carried out by qualified personnel;
the environmental conditions and the electrical plants where the device operates are in compliance with the specifications of the manual and the present regulations concerning electrical plants. In particular grounding reliability and leakage current suppression can only be assured when the device three – wire receptacle is connected to a yellow - green return connected to earth ground. Attempting to defeat the proper connection of the ground wire is dangerous for users and equipment.
3. Before powering the system, check the power cables and the plugs. Damaged electrical parts must be replaced immediately by authorised personnel.
4. Cleaning residue, particulates, and other contaminates (including pieces of torn or broken components) in the breathing circuit pose a safety risk to the patient during testing procedures. Aspiration of contaminates can potentially be life-threatening. You must follow all the cleaning procedures in System Maintenance, and you must thoroughly inspect the components after cleaning and before each patient test.
5. This device is not suitable for use in presence of flammable anaesthetics. It is not an AP nor an APG device (according to the EN 60 601-1 definitions).
6. Keep the device away from heat and flame source, flammable or inflammable liquids or gases and explosive atmospheres.
7. In accordance with their intended use microQuark is not to be handled together with other medical devices unless it is clearly declared by the manufacturer itself.
Chapter 1 - Getting started - 9
8. It is recommended to use a computer with electromagnetic compatibility CE marking and with low radiation emission displays.
9. It is necessary to make the PC, connected to the
microQuark, compliant with EN 60601-1 by means of an isolation transformer.
10. Graphical symbols used in accordance to present specifications are described here below:

Contraindication
The physical strain to execute the respiratory manoeuvre is contraindicated in case of some symptoms or pathology. The following list is not complete and must be considered as a piece of mere information.
Contraindications for the Spirometer tests
Absolute contraindications
For FVC, VC and MVV tests:
Post-operating state from thoracic surgery
For FVC tests:
Severe instability of the airways (such as a destructive bronchial emphysema)
Bronchial non-specific marked hypersensitivity
Serious problems for the gas exchange (total or partial
respiratory insufficiency)
Relative contraindications
For FVC tests:
spontaneous post-pneumothorax state
arterial-venous aneurysm
strong arterial hypertension
pregnancy with complications at the 3
For MVV test:
hyperventilation syndrome
rd
month.
Contraindications for Bronchial provocation tests
The bronchial provocation tests must be executed according to the doctor’s discretion. There are not data that reveal specific contraindication for the bronchial provocation test through inhalation.
The modern standard processes have been revealing secure in several clinical studies. However it is recommendable to respect the following contraindications:
Chapter 1 - Getting started - 11
Absolute contraindications
Serious bronchial obstruction (FEV1 in adults)
Recent myocardium infarct
Recent vascular-cerebral accident
Known arterial aneurysm
Incapacity for understanding the provocation test procedures
and its implications.
Relative contraindications
Bronchial obstruction caused by the respiratory manoeuvre.
Moderate or serious bronchial obstruction. For ex. Predicted
value FEV1 less than 1.51 in men and predicted value FEV1 in women less than 1.21.
Recent infection in the superior air tracts
During the asthmatic re-acuting
Hypertension
Pregnancy
A pharmacology treatment epilepsy

Environmental condition of use
COSMED units have been conceived for operating in medically utilised rooms without potential explosion hazards.
The units should not be installed in vicinity of x-ray equipment, motors or transformers with high installed power rating since electric or magnetic interferences may falsify the result of measurements or make them impossible. Due to this the vicinity of power lines is to be avoided as well.
Cosmed equipment are not AP not APG devices (according to EN 60601-1): they are not suitable for use in presence of flammable anaesthetic mixtures with air, oxygen or nitrogen protoxide.
If not otherwise stated in the shipping documents, Cosmed equipment have been conceived for operating under normal environmental temperatures and conditions [IEC 601-1(1988)/EN 60 601-1 (1990)].
Temperature range 10°C (50°F) and 40°C (104°F).
Relative humidity range 20% to 80%
Atmospheric Pressure range 700 to 1060 mBar
Avoid to use it in presence of noxious fumes or dusty
environment and near heat sources.
Do not place near heat sources.
Cardiopulmonary resuscitation emergency equipment
accessible.
Adequate floor space to assure access to the patient during exercise testing.
Adequate ventilation in the room.
