Gemini
Respiration Monitor - Rats - Large Animals
Respiratory gas measurement has long
been known to be an excellent indicator of respiratory status,
for both spontaneously breathing and artificially ventilated
animals. The GEMINI Respiratory Monitor measures breath-by-breath
oxygen and carbon dioxide concentration for accurate respiratory
status assessment.
The instrument uses the latest technology
fast infrared (CO2) and paramagnetic (O2) measurement cells
for unsurpassed accuracy and long-term stability. Respiratory
rate is computed using the normal inspiration/expiration
excursion of the CO2 signal. Adjustable CO2 and respiratory
rate alarms are standard. Linear voltage outputs are provided
for both gasses and respiratory rate, and a standard RS232
serial port provides data for external monitoring or collection
on a computer.
The measurements and computed results
are reported directly on the front-panel backlit LCD display.
High/Low alarm settings are individually adjustable, and
are stored in non-volatile memory.
These settings are restored when
the unit is next used. Indicator lights and an audible signal
provide status indicators for proper system operation. Measurements
can be displayed as continuous (fast) or peak end-tidal
readings.
The small diameter sample tubing
is connected to the animal's endotracheal tube using the
supplied fittings. All alarm settings are adjusted with
a single knob. Alarm lights are always active, but an audible
alarm can be switched on or off as desired. The gas and
rate outputs are standardized for easy external recording.
The RS232 port provides simple ASCII
formatted data that can be received using any communications
software, and easily imported into a spreadsheet for calculation.
The only maintenance required is periodic inspection or
replacement of the supplied moisture filters. Special input
tubing includes a Nafion® membrane that automatically
dries the sample gas for long, trouble-free monitoring.
A miniature in-line hydrophobic filter prevents water from
entering the analyzer.

Expandable:
The GEMINI monitor includes an open slot for use with any
SYSTEM 1000 instrumentation module. Available modules include
a cardiotachometer (Model CT-1000), blood pressure amplifiers
(Model PM-1000) and many other signal acquisition and processing
functions. A plethysmographic respiration module (Model
RR-1000) uses closed-chamber pressure changes to monitor
respiratory rate for very small animals.
