Datex Ohmeda, GE Modulus SE

Features:
The Modulus SE anesthesia machine provides set flows of
medical gases to the breathing system.
A large selection of gases, vaporizers, ventilators,
and monitors gives you control of your system’s configuration.

Gases and Vaporizers
Comes with O2 (two connections), N2O and air,
plus one more cylinder connection for N2O or Heliox.
Holds three vaporizers.
Low leak rates, accurate flowmeters and a minimum proportion of O2 to N2O permit closed circuit and low-flow anesthesia.

Ventilators and Monitors
Available with the 7900 ventilator –
a microprocessor controlled ventilator with
internal monitors, electronic PEEP,
two modes of ventilation and a pressure
waveform display.
Available with the 7800 ventilator –
a microprocessor controlled ventilator with internal monitors.
The Modulus SE also accepts the Ohmeda Respiratory Gas Monitor or the Ohmeda Rascal II.

Patient Safety
Patient Safety devices decrease the risk of:

Hypoxic mixtures: The Link 25 System keeps the O2 concentration higher than 25% (approximate value) at the common gas outlet for O2 and N2O mixtures. N2O and air or heliox flow stop if the O2 provide decreases to less than 20 PSIG (138 kPa).
Agent mixtures: With correctly installed vaporizers,
you cannot turn on more than one vaporizer at a time.
The vaporizer manifold prevents gas flow through all
vaporizers that are OFF.
Complete power or sudden gas source failures: Batteries continue 7800 and 7900 ventilator operation during a power failure.
Ohmeda ventilators have power failure alarms,
and alarms for low gas source pressure.
The Modulus SE has an alarm for O2 source pressures less than
30 PSIG (207 kPa; approximate value).

Ventilator Option 1: 7800
Systems with the 7800 Ventilator use:
The ventilator to monitor inspiratory O2, expiratory volume, and airway pressure.
The system switch to start gas flow and to turn ON the ventilator.
A pneumatic alarm for low O2 source pressure.
A battery in the ventilator to continue ventilator operation during a power failure.
An outlet box to source electrical power to system components. A transformer in the box provides power for the light.
Ventilator Option 2: 7900
Systems with the 7900 Ventilator use:
The ventilator to monitor inspiratory O2, expiratory and inspiratory volumes, and airway pressure.
The system switch to start gas flow and to turn ON the ventilator.
An electronic alarm on the ventilator for low O2 source pressure.
A battery in the ventilator to continue ventilator operation during a power failure.
Software that adjusts for changes in fresh gas flow,
breathing circuit compliance, and leaks.
An outlet box to provide electrical power to
system components.
A transformer in the box provides power to the light.
The pressure mode provides constant pressure during inspiration.
The volume mode provides constant flow during inspiration.

Accurate flow tubes.
Vaporizers with linear concentrations.
Low leak rates.
An absorber that uses less absorbent.
