What is a Tec 7 Vaporizer?
The Tec 7 Vaporizer is designed for use in continuous flow techniques of inhalation
anesthesia. Each vaporizer is agent specific and is clearly labeled with the anesthetic
agent that it is designed for.
The vaporizer is temperature, flow and pressure compensated so that its output
remains relatively constant despite cooling due to evaporation, variations in inlet flow
and fluctuating pressures as described in Section 7, Effects of Variables.
The vaporizer is designed to be used on Selectatec
vaporizer can be installed on other Selectatec Manifolds but the interlock system is
designed to function on Selectatec Series Mounted Manifolds only. Mounting a Tec 7

3 Setup and Mounting Procedure
Vaporizer mounting procedure
The vaporizer is designed to be used on Selectatec Series Mounted Manifolds. The
vaporizer can be installed on other Selectatec Manifolds but the interlock system is
designed to function on Selectatec Series Mounted Manifolds only.
Mounting a Tec 7 Vaporizer on a Selectatec 7 Compatibility Block is not
recommended.
ww
ww
WARNING Do not lift or support the vaporizer by holding the control dial. Handle the
vaporizer with care at all times.
Before mounting a vaporizer onto the Selectatec Series manifold,
ensure that each manifold port valve O-ring is intact and that there is no
foreign matter around the mating surfaces. A damaged O-ring and/or
foreign matter around the mating surfaces can cause leaks.
Earlier versions of the Selectatec Series Mounted Manifold that provide
mounting positions for three vaporizers require that if only two vaporizers
are fitted, then the center position must be occupied. If the center
position is not occupied, the interlock that helps ensure that only one
vaporizer at a time can be turned ON is ineffective.
Do not use a vaporizer if the liquid level decreases below the minimum
level.

WARNING To help ensure correct operation, do not use a vaporizer that is either
visibly out of line on the manifold or that can be lifted off the manifold
when the locking lever is in the locked position.
If more than one vaporizer is fitted, visually check to make sure that the tops of the
vaporizers are level. If the vaporizer is visibly out of line, perform steps 2 and 3 as
described in Removing the vaporizer from a manifold and remount it correctly.
When the vaporizer appears to be level and the locking lever is in the locked position,
attempt to lift the vaporizer straight up from the manifold. If the vaporizer can be lifted
off the manifold, it is not correctly mounted. Remount the vaporizer (see Vaporizer
mounting procedure ).
Verify that the interlock rods are in alignment by making sure that only one vaporizer at
a time can be turned ON.
Check the anesthesia system for leaks in accordance with the relevant User’s
Reference Manual with the vaporizer dial turned to 0% and then repeat the check with

Filling and draining the vaporizer
ww
ww
WARNING Do not fill the vaporizer with any agent other than the agent specified on
the front label. The vaporizer is designed for that agent only. If any
substance other than that specified is used, patient injury could occur.
Only fill the vaporizer when it is in an upright position. Failure to do so
may result in the vaporizer being overfilled.
To avoid explosive hazards, flammable anesthetic agents such as Ether
and Cyclopropane must not be used in or with this vaporizer. Only
anesthetic agents that comply with the requirements for non-flammable
anesthetic agents in the IEC 60601-2-13 Standard,
Requirements for the Safety of Anesthesia Machines

Particular
, are suitable for
As this vaporizer is not suitable for use with flammable anesthetic agents
such as Ether or Cyclopropane, the use of antistatic breathing tubes and
face masks is not necessary. The use of antistatic or electrically
conductive breathing tubes when using high frequency electric surgery
equipment may cause burns and is therefore not recommended in any
application of this vaporizer.
Do not fill the vaporizer unless the control dial is in the position.
Do not turn the dial ON during filling or attempt to fill beyond the ¥
mark.
Do not drain the agent into any container other than a properly marked
drug container.
Ensure that the filler cap is tightened prior to use.

Tec 7 Vaporizer
When filling the Tec 7 Vaporizer, observe the following:
• Periodically check the agent level. The vaporizer should be refilled at appropriate
intervals. The vaporizer is designed to function according to specification as long
as there is agent visible above the
mark.
• The vaporizer must be filled and used in an upright position. Small deviations
from the upright position do not affect either the output or the safety of the
vaporizer.
• Every two weeks, preferably when the agent level is low, drain the contents of the
vaporizer into an appropriately marked container and discard the agent. Less
frequent intervals may be used when the anesthetic agent does not contain
additives or stabilizing agents, but the procedure must be performed at least
once every year.
• The following steps should be taken for Halothane vaporizers:
— Drain the vaporizer every two weeks
— If Halothane is used infrequently the vaporizer should be drained after use.
— The decomposition of halothane causes the release of halides, which may
corrode metal components particularly in the presence of moisture. Also a
preservative added to halothane by its manufacturers to impede
decomposition can leave a residue, which may cause vaporizer
components to stick.
• If the vaporizer is not upright, check the agent level more frequently to avoid a
misleading impression of the amount of agent in the vaporizer.
Step 1
Turn the vaporizer dial clockwise to the

contaminant (such as water), proceed as follows:
1. Remove the vaporizer from service immediately and label the vaporizer stating
that it is contaminated. Discard all liquid.
2. Return the vaporizer to a Datex-Ohmeda Authorized Service Center stating that
the vaporizer is contaminated and, if possible, the type of contaminant in the
vaporizer.
Connect the Tec 7 to an Anesthesia Machine.
1. Set the oxygen output of the anesthesia machine to a flow of 5± 0.5 L/min.
2. Ensure that the fresh gas output is connected to a gas scavenging system.
3. Measure the concentration at the fresh gas outlet, using an agent monitor which
is calibrated to measure the specific agent.
4. Allow the readings to stabilize and check that the readings are within specified
tolerances.

The performance of most vaporizers that are in clinical use can be confirmed by observing
patient signs and consumption of anesthetic agents. Some users may, however, wish to
employ analyzers either as a routine procedure or as part of an investigation to determine
whether any abnormalities of performance have developed.
To help to achieve the reliability and consistency of performance of the Tec 7 Vaporizer,
Datex-Ohmeda uses closely specified test conditions, test methods and detailed protocol
in conjunction with training, experience and quality auditing systems. For these reasons,
the full program necessary to help to ensure that a vaporizer complies with Datex-Ohmeda
specifications cannot practicably be carried out in a field situation.
The following points must be considered when any measurements are being carried out on
vaporizers to assist in determining whether any abnormalities of performance have
developed.
Min Vol% Max Vol%
1175-0013-000
1. To predict the concentration that the vaporizer can be expected to deliver, the
detailed nominal performance data and the preceding comments must be taken
into account.
2. The method of test used must not be such that it bears little relation to normal
conditions of clinical use.
3. Any sampling techniques used must be such as to ensure the following:
a. The sample is fully representative of the vaporizer output, which may not be a
homogeneous mixture at the vaporizer outlet.
b. The absorption of agent by any connecting tubing is negligible.
4. If a number of vaporizers are being examined at the same time the probability of all
of them being consistently in error is so remote as to be negligible and the cause of
any apparent error probably lies in the test method employed.
5. Consistent and reproducible analytical techniques must be used.
6. If unexpected results are obtained, it is a wise precaution to repeat the observation
because the vaporizer may be more reliable than the techniques used to observe its
performance.
5-3
Page 30
Tec 7 Vaporizer
7. If unexpected results occur, it is also worthwhile checking for sources of error
such as the flowmeter, leaks or absorption by adjacent components.
8. Full account must be taken of any extraneous effects on the analyzer that may
arise from changes in the carrier gas composition.
9. If the anesthetic machine on which the vaporizer is fitted is left for a period of
time with no gases flowing, sensitive analyzers may detect small concentrations
of agent for a short time at the machine outlet after the gas flow is turned ON with
the vaporizer turned to . This is a normal machine characteristic caused by
residual vapor left in the machine from previous use.
10. When the vaporizer is turned from to 0% or above after a period out of use,
an increased concentration may occur that rapidly stabilizes to the set
concentration within approximately 10 seconds at 5 liters/minute flow.
11. At the 0% setting it is normal for small steady concentrations to be observable on
sensitive analyzers.
Analytical techniques
For field checking of the state of calibration, many techniques and analyzers are
available. Datex-Ohmeda would not recommend any one technique or analyzer in
preference to another, but the calibration and reliability of analyzers must be
realistically considered and account must be taken of errors of use.
The following method of checking can be used where special equipment is not
available or where a secondary check of analyzers is desired. The characteristics of the
vaporizer are such that, if the vaporizer is satisfactory at one dial setting, it should be
satisfactory at all other graduations.
1. Ensure that the vaporizer is at least half full and has been at an ambient
temperature of 21 ± 2° C for at least three hours.
2. With the vaporizer securely mounted, drain the vaporizer as detailed in Section 4
and, after draining, ensure that either the drain plug and the filler cap are both
securely tightened or the port valve is fully closed and the locking clamp is in the
up position, as appropriate.
3. Check that the control dial is turned to and then carefully and quickly pour a
measured 50 milliliters of agent into the vaporizer without spilling.
4. Leave the vaporizer at a nominal temperature of 21 ± 2° C for one hour to help to
ensure that the temperature has stabilized.
5. Set the flowrate to 5 liters/minute oxygen.
6. Turn the control dial to 2%, note the time and check that the flowrate is still 5
liters/minute. Readjust the flowrate as necessary.
7. Leave the vaporizer at this setting for 30 minutes. Periodically check and adjust
the flowrate as necessary. Turn the vaporizer to and turn the oxygen OFF.

8. Drain the vaporizer as detailed previously in Instruction 2 and measure the
amount of liquid drained off. The amount of liquid consumed should be as
follows:
Enfluratec 15.5 milliliters
Fluotec 13.5 milliliters
Isotec 15.5 milliliters
Sevotec 16.6 milliliters
Appropriate action must be taken to handle the exhaust gases and spillage.

Note
This method is designed to be a quick and easy check of vaporizer operation and,
therefore , it is somewhat imprecise. However, it is unusual for the measured liquid
consumption to vary by more than 25% of the values listed above.

6 Principle of Operation
Interlock mechanism
The vaporizer locking lever is interlocked with the vaporizer percentage control dial so
that the control dial release, located at the rear of the dial, cannot be actuated until
the vaporizer locking lever is in the locked position.
With the vaporizer locking lever in the locked position, the dial release can be pressed
in toward the dial to operate the interlock mechanism, which allows the manifold port
valves to open, prevents an adjacent vaporizer from being turned on, and allows the
vaporizer to operate.
Turning the control dial to automatically reverses the operating sequence, which
allows the dial release to move out to lock the dial in the position, closes the
manifold port valves and vents the vaporizer gas connecting ports, and allows an
adjacent vaporizer to be turned ON.
Turning the locking lever to the unlocked position releases the vaporizer allowing it to
be removed from the manifold.
Delivery of gas/agent vapor
Overview
The output concentration of the Tec 7 Vaporizer is regulated by the ‘variable flow-split’
method described in the following text and shown in figures 6-1 and 6-2.
A total flow of fresh gas from upstream flowmeters enters the vaporizer from the
flowmeter where it is immediately split into two streams. One stream flows into the
fresh gas bypass circuit and the other stream flows through the vaporizing chamber
where it is enriched with the vapor of the liquid anesthetic agent.
1175-0013-000
6-1
Page 34
Tec 7 Vaporizer
Bypass circuit
1
The bypass circuit includes the gas transfer manifold and also a thermostat assembly
that is located at the base of the vaporizer.
The fresh gas flows through the bypass circuit vertically downwards across the sump
base through the thermostat and back up the gas transfer manifold to the common
gas outlet as shown in Figure 6-1.
The thermostat deflects according to its temperature to control the resistance offered
to the flow of gas through it. This deflection varies the relative proportions of gas
flowing through the bypass and vaporizing chamber circuits.

Figure 6-1 • Bypass circuit
The fresh gas flow through the vaporizing chamber, as shown on Figure 6-2, flows from
the flowmeter across the sump cover where it is diverted through the central cavity of
the rotary valve and back through the Intermittent Positive Pressure Ventilation (IPPV)
compensating assembly.
Gas now flows from the IPPV assembly down through the tubular wick assembly where
it picks up anesthetic vapor and then flows across the base of the vaporizing chamber
above the liquid agent.
From the base of the vaporizing chamber the gas/agent mixture flows through the
sump cover to the proportional radial drug control groove of the rotary valve and then
back into the sump cover where it combines with the fresh gas from the bypass circuit.
The combined total flow then flows out from the vaporizer and via the Selectatec
circuitry to the anesthesia gas delivery system.

The rate of consumption of anesthetic agent depends primarily on flowrate and vapor
output concentration. As an approximate working figure, 1 milliliter of liquid
anesthetic is required to provide 200 milliliters of vapor.
The approximate hourly consumption of anesthetic agents can be expressed as
3 x % x F, where % represents the setting of the vaporizer output percentage and F
represents the input flowrate in liters/minute.
Example: If a vaporizer is set to deliver 2% at 6 liters/minute total gas

= 3 x 2 x 6 = 36 ml/hour.
The figures are approximate and are intended for general guidance only.

anesthetic is required to provide 200 milliliters of vapor.
The approximate hourly consumption of anesthetic agents can be expressed as 3.3 x
% x F, where % represents the setting of the vaporizer output percentage and F
represents the input flowrate in liters/minute.
Example: If a vaporizer is set to deliver 2% at 6 liters/minute total gas

= 3.3 x 2 x 6 = 39.6 ml/hour.
The figures are approximate and are intended for general guidance only.
Barometric pressure The Tec 7 Vaporizer is calibrated in percent v/v at 760 mmHg. If the ambient pressure
changes the % v/v changes, so that at an ambient pressure P mmHg the delivered
percentage (D% v/v) is calculated as follows:
% x 760
D =
To obtain a consistent depth of anesthesia when gross changes of barometric
pressure occur, the % v/v must be changed in inverse proportion to the barometric
pressure.
The vaporizer automatically makes this % v/v change and for practical clinical
purposes the effects of barometric pressure can be ignored.

7 Specifications
Ambient temperature The effects of variation in temperature are normally negligible at commonly used
combinations of dial setting and ambient temperature.
If the vaporizer temperature is above the range shown on the performance curves, the
vaporizer output may be unpredictably high, particularly if the temperature of the
agent approaches the agent boiling point specified by the agent manufacturer.
If the vaporizer temperature is below the range shown on the performance curves, the
vaporizer output may be lower than expected.
To help avoid inaccuracies due to extreme temperatures, before using the vaporizer it
must be allowed to attain a temperature within the range shown on the performance
curves.
Back pressure
wwwwWARNING Pressures in excess of 400 mmHg may overcome the internal pressure
balance and cause a variation in output.
Steady back pressure The vaporizer cannot distinguish between pressures at the outlet due to barometric
pressure and pressures in excess of barometric due to steady back pressures applied
by downstream components. The equation given in the section Barometic Pressure
therefore applies with the term P now being the absolute pressure at the outlet, that is,
barometric pressure plus back pressure. Steady back pressure reduces the % v/v.
Currently, it is unlikely that the steady back pressure imposed by commonly used
downstream components, other than some ventilators, exceeds 30 mmHg at
commonly used flowrates. Back pressures as high as 30 mmHg would reduce the
delivered % v/v, at 760 mmHg barometric pressure, to the following:
760
= 0.96 of what would otherwise be expected.
--------790
790
Under normal clinical circumstances effects of this magnitude can be ignored.
Fluctuating back pressure Fluctuating back pressure may be imposed on the vaporizer by downstream
components and/or assisted or controlled ventilation to the patient. These fluctuating
back pressures can affect the vaporizer and increase the concentration by
intermittently altering the pressures, and consequently the flow distribution, within the
vaporizer.
The greatest effects are observed at combinations of very low flowrates and low dial
setting with large and rapid pressure fluctuations. The effects become progressively
less important as the dial setting and flowrate increase and the magnitude and rate of
cycling of the pressure fluctuations decrease.

Carrier gas composition
ww
ww
WARNING Only operate the vaporizer with dry medical gases.
Time out of service
Effects of variables
Small output decreases can occur when the carrier gas composition is changed from
100% oxygen.
When either air or nitrous oxide is employed as the carrier gas, the output is lowered
compared to the output when oxygen is the carrier gas. This effect is the greatest (up
to 20% of setting) at low flows when nitrous oxide is employed, but using nitrous oxide
reduces the required inspired concentrations of volatile agent that can, depending
upon the proportion, mitigate the decreases in output from the vaporizer.
If the anesthesia machine on which the vaporizer is fitted is left for a period of time
with no gases flowing, small concentrations may be detected at the machine outlet
immediately after the gas flow is turned ON. This is a normal machine characteristic
and is caused by residual vapor left in the machine from previous use.
When the vaporizer is turned from the setting after a period out of use, a brief
high concentration may occur that rapidly stabilizes to the set concentration within
approximately 10 seconds at 5 liters/minute.
These phenomena are normal characteristics of vaporizers. In use the volume of vapor
involved is small compared to the volume of the breathing circuit.
Ambient temperature, input flowrate and duration of use can affect delivered
concentration, particularly when the vaporizers are used at extremes of the usual
clinical range.
Note
Use of the vaporizer at high gas flows and high dial concentrations may affect the
accuracy of delivered concentrations. Refer to Performance Curves in this chapter for
full information.
The valve design and temperature compensation system of Tec 7 Vaporizers reduces
the effects to levels such that, under most clinical conditions, their effect on vaporizer
performance is not clinically significant.

Buyer’s order, but in no event for a period of more than three years from the
date of original delivery by Datex-Ohmeda to a Datex-Ohmeda Authorized
Dealer, this Product, other than its expendable parts, is warranted against
functional defects in materials and workmanship and to conform to the
description of the Product contained in this User’s Reference Manual and
accompanying labels and/or inserts, provided that the same is properly
operated under the conditions of normal use, that regular periodic
maintenance is performed and that replacements and repairs are made in
accordance with the instructions provided. This same warranty is made for a
period of thirty (30) days with respect to expendable parts. The foregoing
warranties shall not apply if the Product has been repaired other than by
Datex-Ohmeda or in accordance with written instructions provided by
Datex-Ohmeda, or altered by anyone other than Datex-Ohmeda, or if the
Product has been subject to abuse, misuse, negligence, or accident.
Datex-Ohmeda’s sole and exclusive obligation and Buyer’s sole and exclusive
remedy under the above warranties is limited to repairing or replacing, free of
charge, at Datex-Ohmeda’s option, a Product, which is telephonically
reported to the nearest Datex-Ohmeda Customer Support Center and which, if
so advised by Datex-Ohmeda, is thereafter returned with a statement of the
observed deficiency, not later than seven (7) days after the expiration date of
the applicable warranty, during normal business hours, transportation
charges prepaid, and which, upon Datex-Ohmeda’s examination, is found not
to conform with above warranties. Datex-Ohmeda shall not be otherwise
liable for any damages including but not limited to incidental damages,
consequential damages, or special damages.
There are no express or implied warranties which extend beyond the
warranties hereinabove set forth. Datex-Ohmeda makes no warranty of
merchantability or fitness for a particular purpose with respect to the product
or parts thereof.
