Safety-related information
2 Safety-related information
2.1 Intended use
This device is intended for use in anesthetizing adults, pediatric patients, and
neonates. The device can be used for mechanical ventilation, manual ventilation,
pressure-supported spontaneous breathing, and spontaneous breathing.
The device is equipped with the following basic functions:
– Ventilation monitoring
– Inspiratory O2measurement
– Device monitoring
– Anesthetic gas receiving system
The following options are additionally available:
– Patient-gas measurement module for O2, CO2, N2O, and anesthetic gases
–O
2insufflation
Anesthesia is achieved through a mixture of pure oxygen and Air (medical
compressed air) or pure oxygen and nitrous oxide, with the addition of volatile
anesthetic agents.
Ventilation is accomplished on the patient through a laryngeal mask, a breathing
mask, or an endotracheal tube.
The integrated breathing system can be used with partial rebreathing (low-flow or
minimum-flow).
A non-rebreathing system, such as the Bain, Mapleson, Kuhn, or Waters system,
may be used at the external fresh-gas outlet.
2.2 Indications
The device is specified for inhalational anesthesia and/or patient ventilation in
accordance with the intended use during surgical or diagnostic interventions.
2.3 Contraindications
The device has no product-specific contraindications.
It is the responsibility of the user to select the appropriate treatment for the patient’s
underlying disease. The patient's condition must be continually monitored for any
potential changes.
The safety information must be followed for patients suspected of malignant
hyperthermia, patients with ketoacidosis, and patients who are under the influence
of alcohol. Observe the following information: "Therapy and applications", page 89.
The device administers medical gases such as O2, N2O, Air (medical
compressed air), and volatile anesthetic agents (halothane, enflurane, isoflurane,
sevoflurane, desflurane). For contraindications to the applied medical gases, strictly
follow the instructions for use of the medical gases.

10 Instructions for use | Atlan A300, A300 XL, A350, A350 XL SW 1.0n
Safety-related information
2.4 Environments of use
The device is designed for use in rooms in which therapeutic or diagnostic
interventions can be performed under constant supervision of users. According to
IEC 60601-1-2, the use of the device is only permissible in hospitals and
comparable facilities with a Class A electromagnetic environment.
Do not use the device in the following environments:
– Outside buildings
– On intensive care units
– During patient transport
– In vehicles, airplanes, helicopters, and on ships
– In areas where oxygen concentrations above 25 Vol% or combustible or
explosive gas mixtures can occur.
– In rooms with magnetic field applications (e.g., magnetic resonance imaging)
2.5 Essential performance features
Correct functioning of the essential performance features ensures that the product
can be used in accordance with its intended use. The product has the following
essential performance features:
General
– Supply of the anesthesia workstation with O2:
If the O2supply (central gas supply or gas cylinder) fails, an alarm is issued.
– Supply of the patient with adequately oxygenated breathing gas:
If the breathing gas contains insufficient levels of O2, an alarm is issued.
– Supply of an adequate anesthetic gas concentration to the patient:
When the anesthetic gas is measured by means of an integrated patient-gas
measurement module, an alarm will be generated if the anesthetic gas
concentrations are too high.
– Monitoring of the airway pressure:
Alarms are issued depending on the set alarm limits.
Gas measurement
– Breathing gas monitoring:
– Set values for FiO2
– Inspiratory and expiratory measured values for O2, CO2, N2O, and
anesthetic gas; automatic anesthetic agent identification (patient-gas
measurement module)
The gas composition is measured with ISO accuracy.
– Monitoring of breathing gas concentrations:
Alarms will be issued depending on the set alarm limits or if the gas
measurement fails.
