Sensitivity Modes
Three sensitivity levels enable a clinician to tailor the response of the Radius-7 to the needs
of the particular patient situation. The sensitivity levels are as follows:
• NORM (Normal Sensitivity)
NORM is the recommended sensitivity mode for patients who 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).
• APOD® (Adaptive Probe Off Detection Sensitivity®)
APOD is the recommended sensitivity 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.
• MAX (Maximum Sensitivity)
MAX is recommended sensitivity mode for patients with low perfusion or when a
low perfusion message displays in APOD or NORM mode. MAX 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.
