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
• 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.
