Masimo EMMA - Chapter 1: Technology Overview; Principles of Operation

Saturated Capnogram
5 User Interface
5.1 Controls
EMMA has one Power On and one Alarm Silence button. These buttons may also be used for adjusting
the Low and High ETCO
2
alarm limits up and down.
5.2 Monitoring
EMMA is fitted with a graphic OLED-display that shows the ETCO
2
value, the Respiratory Rate and a
CO
2
waveform (the capnogram).
5.2.1 ETCO
2
EMMA is available in two versions displaying ETCO
2
either in mmHg (0 - 99 mmHg) or kPa (0.0 - 9.9
kPa). ETCO
2
values are displayed after one breath and the averaged value is updated every breath.
5.2.2 Respiratory Rate
Respiratory Rate (RR) is displayed as breaths per minute (3 - 150 bpm). RR is displayed after two
breaths and the value is updated every breath.
5.2.3 Capnogram
The capnogram is displayed as a filled graph with a 14.4 sec horizontal sweep and a fixed 0-53
mmHg/0-7 kPa scale.
Figure 9. EMMA Display
If the CO
2
level reaches or exceeds 53 mmHg/7 kPa, a horizontal dashed line will be displayed to
indicate that the capnogram is saturated.
