significant immunity to ambient or strobing light, excessive ambient or excessive strobing
light may cause readings to be incorrect.
CAUTION:
IF ANY MEASUREMENT SEEMS QUESTIONABLE, FIRST CHECK THE
PATIENT’S VITAL SIGNS BY ALTERNATE MEANS AND THEN CHECK THE
PULSE CO-OXIMETER FOR PROPER FUNCTIONING.
SENSITIVITY
Three sensitivity levels enable a clinician to tailor the response of the Radical-7R to the needs
of the particular patient situation. They are as follows:
■
Normal Sensitivity – This is the recommended mode for patients that are experiencing
some compromise in blood flow or perfusion. It is advisable for care areas where patients
are observed frequently, such as an intensive care unit (ICU).
■
Adaptive Probe Off Detection (APOD) – This is the recommended monitoring mode where there
is a high probability of the sensor becoming detached. It is also the suggested mode for care
areas where patients are not visually monitored continuously. This mode delivers enhanced
protection against erroneous pulse rate and arterial oxygen saturation readings when a sensor
becomes inadvertently detached from a patient due to excessive movement.
■
Maximum Sensitivity (MAX) - This mode is recommended for patients with low perfusion or
when the low perfusion message is displayed on the screen in APOD or normal sensitivity
mode. This mode is not recommended for care areas where patients are not monitored
visually, such as general wards. It is designed to interpret and display data at the measuring
site when the signal may be weak due to decreased perfusion. When a sensor becomes
detached from a patient, it will have compromised protection against erroneous pulse rate
and arterial saturation readings.
CAUTION:
WHEN USING THE MAXIMUM SENSITIVITY SETTING, PERFORMANCE
OF THE SENSOR OFF DETECTION MAY BE COMPROMISED. IF THE
INSTRUMENT IS IN THIS SETTING AND THE SENSOR BECOMES
DISLODGED FROM THE PATIENT, THE POTENTIAL FOR FALSE READINGS
MAY OCCUR DUE TO ENVIRONMENTAL ‘NOISE’ SUCH AS LIGHT, VIBRATION
AND EXCESSIVE AIR MOVEMENT.
