Radical-7 Chapter 4: Operation

Overview of Sensitivity Modes
Three sensitivity levels enable a clinician to tailor the response of the Radical-7 to the needs
of the particular patient situation. Access the menu by tapping on the indicator in the upper
left corner of the Display View.
The sensitivity levels 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) Sensitivity
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.
Toggle between the sensitivity modes by pressing the indication on the top left of the
Display View. The sensitivity mode also can be changed in the Profile menu which is
accessible from the Main Menu.
Note that the device will revert to APOD mode after a power cycle.
See Changing Profiles Settings on page 90.
