Desflurane Compensation - Mathematical correction applied to the CO
2
measurement to
account for the effects of Desflurane on the CO
2
concentration.
Differential Pressure Transducer - An electronic device that converts a nonelectrical parameter
into an electrical signal. A differential transducer has two inputs and produces an
output signal that is a function of the difference between the inputs. It is used together
with a fixed resistance across the inputs to measure gas flow.
EEPROM - Electrically Eraseable Programable Read Only Memory.
EN864 - Standard for Capnometers for use with humans.
ETCO
2
- End-Tidal CO
2
; the measured carbon dioxide value at the end of an exhaled breath.
ETCO
2
Monitor - A device that provides a numeric and/or graphical display of the end-tidal CO
2
value. Monitors typically include alarm parameters.
ETCO
2
Waveform - A graphical display of end-tidal CO
2
.
Exhaust Occlusion - Obstruction of the exhaust port or tubing downstream from the pump.
Fault State - A state in which the Module detects an internal operating error.
Flash - A type of EEPROM that can be reprogrammed in-circuit.
Forward Flow - A condition that causes a positive pressure on the Module’s input pneumatics or
CO
2
inlet port before the Module’s pump is activated.
Gas Canister - Typically a pressurized cylinder containing a known concentration of a specific
gas.
Hard Fault - Condition that halts Module operation and prevents the Module from accepting
commands. The software reset command (
clear a hard fault.
Hard Reset - Reset caused when the host holds the receive data line in a break condition for
more than 500 msec. The microprocessor is forced to enter the boot mode when the
break condition is released. The microprocessor boot mode is used to install new
software into the FLASH device.
HCV - High Clearing Vacuum.
Host System - The main system that controls the LC101 Module within a device.
IEC - International Electrotechnical Commission.
IEC 601-1 - Medical electrical equipment part 1: General Requirements for Safety.
