cylinder. Our service technician can set the rate at which the volume
under the piston is eliminated. If you would prefer it work faster or slower
give us a call we can make the change for you over the internet.
Buffer Volume Setting
To set the buffer volume depress the TV control and hold it for 3 seconds.
The
of the screen will change to BV, release the
knob. Turn the knob to the desired setting and depress it again to save
the new setting. The BV value on the display will update with the new BV
setting and the knob will revert to controlling the set TV. The default BV
setting is 5.0 liters.
Controls on the Anaesthesia Machine Side
These controls are on
Tafonius Junior
w/gas and include the oxygen flowmeter, air
and N
2
O flowmeters if fitted, the oxygen flush button and scavenging flowmeter. If you have
the version of
Junior
that is sans gas (the ventilator only) these controls would be found
on your existing anaesthesia machine if fitted.
Oxygen Flowmeter
The oxygen flowmeter has a 0 -10 lpm scale but considerably more flow can be delivered
when the ball is off the top of the scale. Use this flowmeter as you would on any other
anaesthesia machine.
Air Flowmeter
An optional air flowmeter with either a yellow knob for the US or a black and white knob for
most other countries may be installed on your machine. This allows the user to adjust the
FiO
2
delivered to the breathing system.
The nomogram shown below can be used as a guide for setting the FiO
2
but it is easy to
remember that:
Equal flows of air and oxygen yields 60% O
2
3 times as much air as oxygen yields 40% O
2
3 times as much oxygen as air yields 80% O
2
N
2
O Flowmeter
Although the use of N
2
O is much a thing of the
past this option is still available but should never
be used without a working oxygen analyzer in the
breathing circuit.
Oxygen Flush Button
The oxygen flush button delivers a high flow of
pure oxygen to the breathing system without
going through the vaporizer. It is generally used
to fill the system quickly or to quickly dilute the
anaesthetic concentration in the system.
Scavenging Flowmeter
This flowmeter is located on the right side near the rear of the machine. It is used only when
the machine is connected to a central vacuum system such as is used for surgical suction.
Adjust the scavenging flow to the minimum flow possible to extend the life of your vacuum
pump. The scavenging flow should be set enough to keep the reservoir bag flat at most
times.
