Operation
Low SpHb
When the signal quality for SpHb is very low the accuracy of the measurement may be
compromised. In a low SpHb SIQ state, the parameter label will flash and either the SpHb value
will be displayed or there will be dashes depending on how the user has configured this feature.
Refer to the Factory Default and User Configurable Settings section for details.
Signal Indication and Quality Indicator - Acoustic (SIQa)
SIQa displays the confidence level of the measured signal. A high confidence level displays as a
tall signal. When the SIQa is high and the parameter label flashes, there may be interference from
excessive ambient or environmental noise. A low confidence level displays as a small signal. A very
small signal, with a red bar, may indicate that the accuracy 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 must be well secured to the site for the Rad-87 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 affecting 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 Rad-87 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 Sensor'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.
