4-8 Radical-7 Signal Extraction Pulse CO-Oximeter Operator’s Manual

Operation

SENSITIVITY

Three sensitivity levels enable a clinician to tailor the response of the Radical-7 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.
