Simulating Apnea (Respiration Standstill)

Apnea is described as the cessation of breathing. In general there are three types of apnea:
central (often seen in infants, when there is no diaphragm movement and no air flow);
obstructive (where an object, such as food, is lodged in the trachea); and mixed (where
central apnea is followed immediately by obstructive apnea).
The MPS450 offers four apnea simulations, including three apnea conditions available as
preconfigured, one-time events (with apnea lasting for a duration of 12, 22, or 32
seconds), plus continuous (user-controlled) apnea.
Action in the Menu-Control Mode
1. Press the top-menu key labeled RESP. If the apnea on/off setting has not been
2. Select APNE to display the LCD screen RESPIRATION APNEA.
3. If the apnea setting has not been changed, the LCD screen references the default
4. For a one-time event of 22-second or 32-second apnea, or for a continuous-apnea
5. To terminate a running simulation of apnea at any time (including continuous apnea),
6. To return to the top menu RESPIRATION, press the ESC key.
Alternatively, in the Numeric-Control Mode, press the number keys for an apnea
condition according to Table 3-5, and select RUN:
APNEA ON CONTINUOUS
APNEA OFF
APNEA 12 SECONDS
APNEA 22 SECONDS
APNEA 32 SECONDS

Temperature (Adjusting Body Temperature)

All temperatures output by the MPS450 are compatible with Yellow Springs, Inc. (YSI)
Series 400 and 700 probes. The type of probe simulated is based on the type of cable
connected to the MPS450 and/or the input used. (Cables for connection to the 400 or 700
are available directly from Fluke Biomedical.)
The MPS450 simulates four preconfigured body temperatures, which can be applied at
any time while operating the instrument.
The MPS450 simulates four preconfigured temperatures of the human body, accurate to
within 0.40 C: freezing (0 C / 32 F); hypothermic (24 C / 75.2 F); normal (37 C /
