Performing a test using the canopy option
The principle of a ventilated bubblehood system is that a stream of air is forced to pass
across the face of a subject and mixes with the air which is collected by a transparent
hood, placed over the subject’s head. A measurement system, knowing the flow rate,
calulates the oxygen consumption and the CO
2
production and, starting from these
values, the energy expenditure.
Calibrations
Before the test, it is necessary to perform an ergo calibration (see Calibration chapter)
and it is advisable to perform also a turbine calibration (see Recommendations in this
chapter).
How to prepare the canopy and the patient
Replacement of the power plug
If the power plug does not fit into the mains socket, replace it with the one in the
packaging.
In order to replace the plug:
1. Extract the plug from the battery charger
2. Insert the proper plug in the battery charger.
Connecting the Canopy
1. Connect the Canopy unit to the mains by means of the medical grade AC/DC
adapter provided.
2. Insert the bubblehood adapter into the bubblehood from the outside and fix it
screwing the ring from the inside, being careful to insert it in the proper hole, as
shown in the following picture.
3. Connect the bubblehood to the wrinkled tube, interposing a bacterial filter.
4. Connect the wrinkled tube to the unit through the Flow in connector.
5. Connect the optoelectronic reader of the Quark to the Flow out connector of the
Canopy unit through the spirometry adapter.
6. Fix the vail to the bubblehood through the velcro strips.
