SIGNAL INDICATION AND QUALITY INDICATOR - ACOUSTIC (SIQa)
SIQa displays the confidence level of the measured signal. A high confidence level
displays as a high percentage. When the SIQa is high and the parameter label flash-
es, there may be interference from excessive ambient or environmental noise. A low
confidence level displays as a low percentage. A very small signal, with a red bar, may
indicate that the acuracy of the respiration rate measurement may be compromised.
Whenever the parameter label flashes, proceed with caution and do the following:
■
Assess the patient.
■
Check the Acoustic Respiration sensor and ensure proper sensor application.
■
The Acoustic Respiration sensor and ensure proper application. The Acoustic
Respiration sensor must be well secured to the site for the Radical-7R to
maintain accurate readings. Refer to the Acoustic Respiration sensor's
Directions for Use for proper sensor placement.
■
Identify and remove excessive ambient or environmental noise sources affect-
ing the Acoustic Respiration value.
RESPIRATION INDICATOR (RI)
The Respiration Indicator (RI) displays the sound level of the measured signal. A high
sound level displays as a tall signal. A low sound level displays as a small signal. When
the signal quality is very small the accuracy of the respiration rate measurement may be
compromised. When the RI is small, the bar turns red and the parameter label flashes.
Proceed with caution and do the following:
■
Assess the patient.
■
Check the Acoustic Respiration sensor and ensure proper sensor application. The
Acoustic Respiration sensor must be well secured to the site for the Radical-7R to
maintain accurate readings. Refer to the Acoustic Respiration sensor's
Directions
for Use
for proper sensor placement.
ACOUSTIC RESPIRATION SENSOR PLACEMENT
■
Only use on adult patients weighing > 30 kg.
■
The preferred measuring site is to either side of the larynx, in the area just above
the thyroid cartilage and below the jaw line. Refer to the Acoustic Respiration sen-
sor's
Directions for Use
for proper sensor placement.
■
Site should be hair-free, cleaned of debris and dry prior to sensor placement. Use
an alcohol swab to clean the neck area, if needed.
■
Ensure that the Acoustic Respiration sensor, Acoustic Respiration Patient Cable
and Dual Rainbow Cable are all securely connected.
NOTE:
When the Acoustic Respiration Sensor is off the patient and is connected
to the system the sensor may pick up periodic ambient sounds and
report a measurement. The sensor should only be connected to the
Acoustic Respiration Patient Cable while performing patient monitoring. If
the patient is not being monitored, the sensor should be disconnected from
the Acoustic Respiration Patient Cable.
