2 Introduction
2.1 Intended Use
The HEYER Pasithec is a compact and integrated anesthesia transmitting system. The anesthetic
ventilator not only provides patients undergoing operations with auto ventilation, but also monitors and
displays the patient’s various parameters.
The anesthetic ventilator used in the system is controlled by a microprocessor, which internally
configures the monitor and the volume mode; other functions are optional.
Not all the optional functions available may be included in the manual. It is also possible to add other
equipment to the top or middle of this system for added functions. For more information with respect to
the existing product, please contact your local representatives.
WARNING: All Pasithec users must be trained.
WARNING: HEYER Pasithec is not suitable for use in an MRI environment.
2.1.1 Range of Use
Pasithec is applicable for patients of over 2 kg with standard configuration. Pasithec is for use in the
Operating Room and/or Emergency Room of a hospital, drug addiction treatment center, or other
medical facilities where anesthesia is used.
2.1.2 Contraindication
Pasithec is not suitable for pneumothorax patients
2.2 Symbols
Warnings and Cautions indicate all the possible dangers in case of violation of the
stipulations in this manual. Refer to and follow them.
WARNING: Indicates potential hazards to operators or patients.
CAUTION: Indicates potential damage to equipment.

3 System Components
3.1 Anesthetic System
CAUTION: The anesthetic system is intended to be used with the following monitoring
devices, alarm systems, and protection devices:
+ pressure measuring in accordance with 8.1 of ISO 8835-2;
+ system is to be equipped with an ANESTHETIC GAS SCAVENGING
TRANSFER and RECEIVING SYSTEM complying with ISO 8835-3 before
being put into service.
+ pressure limitation device in accordance with 51.101.1 of IEC60601-2-13;
+ exhaled volume monitor in accordance with 51.101.4 of IEC60601-2-13;
+ breathing system integrity alarm system in accordance with 51.101.5 of
IEC60601-2-13;
+ continuing pressure alarm in accordance with 51.101.6 of IEC60601-2-
13;
+ O2 monitor in accordance with ISO 21647.
+ CO2 monitor in accordance with ISO 21647.
+ ANESTHETIC monitor in accordance with ISO 21647.
WARNING: To avoid explosion hazards, flammable anesthetic agents such as Ether and
Cyclopropane shall not be used in the anesthetic workstation. Only use
anesthetic agents that comply with the requirements for non-flammable
anesthetic agents as specified in this manual. Halothane, Desflurane,
Sevoflurane, Enflurane, and Isoflurane have been found to be nonflammable agents.
WARNING: Independent means of ventilation (e.g. a self-inflating manually powered
resuscitator with mask) should be available whenever the anesthetic system
is in use.
WARNING: Do not use antistatic or electrically-conductive breathing tubes and mask.
WARNING: Contact with a liquid, such as anesthetic agent, results in damage within the
device.
WARNING: The incline angle should not exceed 10 degrees whenever the anesthetic
system is in use.
