he gas-mixing unit serves as proportioning device for medical gases
T
(e.g. oxygen, nitrous oxide and compressed air).The desired gases can be
mixed in any relation by means of the proportioning valves below the
flowmeter tubes. The types of gas can be clearly recognized on the
control knobs.
To prevent conf
usion, the control knob of the regulating valve for oxygen
differs haptically from the two other valves. Inadvertent shift of the
settings is avoided by a special twisting-prevention device.
he proportioning valves (control knobs) permit a continuous flow, when
T
they are rotated counterclockwise. The measuring area for O
consists of

two flowmeter tubes, so that an exact proportioning is guaranteed.

6 Circle System
6.1 Design and Description of Performance
The circle system together with the patient forms a closed cycle, into
which fresh gas is fed via the fresh gas pipe line. Excess gas escapes
through the excess gas valve (10)from the cycle and is removed from the
field of activity of the anaesthetist by means of the suction system for
anaesthetic gas (13).During the inspiration phase, the gas contained in the
system is transported to the patients' lungs by effecting pressure,
produced either by the respirator or by manual operation of a respiratory
bag. The consequent PRESSURE RELIEF in the system during the
expiration phase and the increase of pressure in the lungs due to the
elasticity of the thorax makes the gas flow back out of the lungs. Thereby
it is the task of the inspiration valve (1) and the expiration valve (7) to
permit the flow of gas only in one direction and so to establish the cycle.
Prior to reaching the patient again, CO
(2). Humidity and heat given off by the patient are fed back to him in
such a semi-closed system, which prevents desiccation and excessive
cooling of the airways. The fresh gas feeder is located on the lower end of
the holding tube. The adjustability of elevation and the possible
swivelling stand for a good adaptation to the local conditions of the
operating theatre. The respiratory pressure gauge(3), which can be
slipped onto the holding device of the circle system, has a measuring
range from - 10 to 100 mbar. It can be replaced by a blind plug.
is removed in the two absorbers
2
6 Circle System
As a standard, a mechanic volumeter (9) is installed below the expiration
valve, which measures all expiratory values of respiratory volume. The
measuring of O
in accordance with DGAI, is carried out by means of a polarographic cell
(by Clark) (1) at the head of the inspiration valve. Moreover, the circle
system is provided with connection tapers in accordance with ISO
respectively DIN 13 252, so that corrugated tubes for the ventilation of
adults as well as tube systems for infants can be used. The excess valve
(10) serves to carry off spent respiratory gases. It can be operated in four
different adjustments.

-concentration, required
2
6 Circle System
6.1.1 CL (closed)
The valve is completely closed. This setting is necessary for operation in
respirator mode. In this mode, the spent respiratory gases are evacuated
via the ejector on the patient component during the expiration phase.
6.1.2 Pressure Range from 5mbar to 50mbar
This setting is used to limit the maximum pressure during manual
ventilation. When the set pressure is reached, the valve evacuates.
6.1.3 Spontaneous Respiration
During spontaneous respiration of the patient under light anaesthesia, the
valve closes in the inspiration phase, the patient now breathes the fresh
gas provided by the apparatus. In the expiration phase, the valve opens
and evacuates the system until ambient pressure is reached.
This setting is to be used in case of assisted ventilation with the patient
triggering the respiration and the respirator deepening the respiration.
Aside of that, it is possible to switch to SP briefly in case of manual
ventilation in the pressure range of 5 to 50 mbar to evacuate an overfilled
respiratory bag.
6.1.4 VOL (volume-controlled ventilation)
With the valve setting VOL, the circle system is closed automatically to
guarantee supply of the patient with the desired respiratory working
volume. Spent and excess respiratory gases escape from the valve at the
end of the expiration phase. During the expiration phase, pressure in the
system never rises above 1,5 mbar.
