case, because it's
mixed with fresh air
coming into the oxy-
gen mask, ETCO2
might only read 15
mmHg.
If the patient's respi-
ratory rate increases
(hyperventilation),
the CO
2
waveform
becomes smaller and
more frequent, and
the numeric reading
falls below the nor-
mal range. If respira-
tion decreases
(hypoventilation), the
waveform becomes
taller and less fre-
quent, and the numer-
ic reading rises above
the normal range. If
the square waveform
starts to collapse,
there's an airway
obstruction. If the
square becomes a flat
line, the patient is not
breathing.
Is your ventilatory vision 20/20?
We can help you
see more clearly.
As recommended by the ASA, pulse
oximetry may be inadequate for
monitoring of hypoventilation in
sedation. However, studies indicate
that "reliable" CO2 values may not
be attainable utilizing etCO2. Visit
