Introduction7

Description of the SpotOn temperature monitoring system

The SpotOn temperature monitoring system measures the core temperature of the patient. The system is comprised of the SpotOn temperature sensor, which connects to the SpotOn control unit through the sensor cable, a power supply, and an optional monitor cable. For additional sensors, sensor cable, power supply, control unit stand, monitor cable, hook-and-loop, or foam adhesive, contact 3M Patient Warming.

8Introduction

How it works

The SpotOn temperature monitoring system uses zero-heat-flux thermometry to accurately measure a person’s core temperature as characterized in Figure 1-2 below. 1) The SpotOn temperature monitoring system gently warms the sensor creating an isothermal pathway under the sensor. 2) Once equilibrated to the core temperature, skin-surface heat loss to the environment is prevented and a zero-heat-flux condition is established. 3) When the temperature sensor reaches equilibrium with the patient’s core temperature, the SpotOn control unit displays an accurate, noninvasive measurement of the patient’s core temperature. Temperature Sensor

2) Equilibration - isothermal pathway development

3) Equilibrated - isothermal pathway established Figure 1-2: Isothermal pathway formation with zero-heat-flux technology

SpotOn control unit

The SpotOn control unit displays non-invasive core temperature measurements obtained from the SpotOn temperature sensor. The current temperature is displayed numerically, and previous temperature data is displayed graphically as a temperature trend graph. When the sensor is plugged into the sensor cable and equilibration is complete, the control unit reads up to the last two hours of stored temperature data and displays the temperature trend graph. Disconnections of the sensor from the sensor cable are indicated by gaps in the temperature trend graph. The current temperature measurement can be continuously transmitted to a patient vital signs monitor through the optional SpotOn monitor cable using a standard YSI-400 type input.

SpotOn temperature sensor

The SpotOn sensor is constructed of two layers of medical grade foam and a flexible circuit which contains a resistive warming circuit, two calibrated thermistors, and nonvolatile memory. The information that generates the temperature trend graph is stored on the SpotOn sensor. When the patient is transferred from one location to another, the SpotOn sensor is disconnected from the SpotOn sensor cable so the sensor is left in place on the patient. The SpotOn sensor may be reconnected to a different SpotOn sensor cable and control unit when the patient arrives at the next point of care. Once the SpotOn sensor is reconnected to the SpotOn sensor cable, the system will begin to reequilibrate and will regenerate the stored temperature trend graph and display the patient’s current temperature. The act of disconnecting and reconnecting the SpotOn sensor from the sensor cable is indicated by a gap in the temperature trend graph.

Installation9

Section 2: Installation 1.

WARNING:

To reduce the risks associated with access to critical patient information or equipment do not mount the control unit: • • • •

To a surface that is not flat or clean. Over air vents of other equipment. Over controls, displays, or buttons of other equipment. Over speakers or alarms of other equipment.

Mounting the SpotOn control unit CAUTION: To prevent injury, mount the SpotOn temperature monitoring system at a height no higher than 84” (213 cm). 1.

Use the provided hook-and-loop or foam adhesive to secure the control unit stand to any hard, flat surface (use only the 3M provided/specified control unit mounting materials).

Note: Confirm the hook-and-loop is securely fastened together before mounting the control unit to a surface. Recommend: Clean surface with a 70% mixture of isopropyl alcohol and water prior to applying the provided hook-and-loop or foam adhesive. 2.

The SpotOn control unit’s height and orientation can be adjusted by loosening/tightening the control unit stand knob on the back of the unit.

Equilibration

A flashing yellow temperature display indicates the sensor has been connected to the patient and to the control unit and is in the process of equilibration. The graph below the temperature output indicates the progress of equilibration. This process will take approximately three minutes. If you see a temperature in the upper left hand corner of the screen, that is the last recorded temperature that has been captured by the sensor. The sensor captures and records a temperature every five minutes.

After the equilibration is complete, the core temperature of the patient is displayed on the SpotOn control unit in bold white numbers and can be automatically transmitted to the patient monitor via the monitor cable.

Running

The running screen displays the core temperature of the patient in white. The trend graph at the bottom of the screen displays up to the last two hours of the patient’s temperature in five minute increments. The bars on the graph will begin filling from the right with the 36°C always visible. The blue bars indicate that the temperature dropped below 36°C (white indicates the temperature is above 36°C).
