NOTE: Inaccuracy specifications are affected by the breath rate and I:E change.
The end-tidal gas reading is within specification for breath rate below
15BPM and I:E ratio smaller than 1:1 relative to the gas readings
without breath; Add ±6%REL to inaccuracy for HAL and O2 for breath
rate larger than 15 BPM; Add ±6%REL to inaccuracy for all gases for
breath rate larger than 30 BPM(inaccuracy for HAL and O2 are
unspecified in this case); inaccuracy is unspecified for breath rate larger
than 60 BPM.
NOTE: The ability to properly resolve end-tidal values can be measured by
using the set-up described in ISO 80601-2-55:2011 figure 201.101. In
short, the method consists of sampling gas from two different sources
connected to an electrically controlled pneumatic valve to permit rapid
switching between the two sources. During the test, the valve is set to
switch gas source at a number of frequencies (simulating the range of
specified breath rates) and for each frequency the end-tidal value
presented by the gas analyzer is noted. From a diagram of end-tidal
value over frequency, the frequency at which the gas analyzer is no
longer able to resolve end-tidal values according to specification is
identified. This ability to properly resolve end-tidal values is listed in
the corresponding AION? Multigas Analyzer technical specification.
NOTE: Data sample rate 25 Hz. Data presentation is 50 Hz, every second data
point is interpolated.
NOTE: Inspiratory and end tidal CO2 concentration readings are identified by
AION? Platinum Multigas Analyzers using the lowest and highest
values respectively of the temporal CO2-curve. Corresponding
readings of N2O and anesthetic agents are taken at the same point in
time. Inspiratory and end-tidal O2 concentration readings are
identified by the O2 mean value during the respiratory phase as
identified by the temporal CO2 curve. Once correctly identified, the
highest and lowest O2 concentration readings during each part of the
phase will be presented as inspiratory and end-tidal O2 respectively.
