You may check the Chest Sensor battery status by pressing the Patient Call Button when the device is off. Do not press and hold. Briefly after pressing the Patient Call Button, the Chest Sensor LED will briefly display a color for 4 seconds. The displayed color will indicate the battery status – see the table below for the color representations: Use the battery status indication to guide your decision about whether that Chest Sensor has enough charge to be used for a certain period of time. If the Chest Sensor indicates low battery (red or blinking red), please consider
_____________________________________________________________________________________________________________________________ Chest Sensor IFU Page 11 of 28 charging the Chest Sensor or using a different device. See the ‘Charging the Chest Sensor’ section for instructions on charging. Device Cleaning Use disinfecting wipes to clean the Chest Sensor and Adapter prior to patient application. The following may be used for cleaning the Chest Sensor and Adapter:  Isopropyl Alcohol (70% Alcohol/water mixture)  Hydrogen Peroxide  Ethyl Alcohol (50% Alcohol/water mixture)  Water Figure 3 Attach an Adapter Depending on where you want to monitor pulse oximetry, you may choose either a L2050F Adapter or L2050E Adapter. Slide the Chest Sensor into the Adapter so that the 30-Pin connectors mate. Ensure that the Chest Sensor is properly aligned on the Adapter rails.
_____________________________________________________________________________________________________________________________ Chest Sensor IFU Page 12 of 28 Figure 4 Caution: Ensure when sliding the Chest Sensor into the Adapter that the 30-Pin connectors are fully mated. Snap two (2) electrodes into the back of the Adapter. Ensure there is no overlap between the two electrodes. Caution: Ensure that when snapping the two (2) electrodes into the Adapter that there is no overlap between the electrodes.
_____________________________________________________________________________________________________________________________ Chest Sensor IFU Page 13 of 28 Snap four (4) electrodes into the RA, LL, and V lead snaps. Device Placement Peel off the adhesive liner from all six (6) electrodes. Attach the Chest Sensor with Adapter to the upper left pectoral area of the patient’s chest. Ensure that the device is positioned correctly per the image below.
_____________________________________________________________________________________________________________________________ Chest Sensor IFU Page 14 of 28 Affix the two Right Arm (RA) electrodes to the upper right pectoral area of the patient’s chest. Ensure the leads are positioned correctly per the image below. Affix the Left Leg (LL) electrode to the patient’s left abdominal area, below the Chest Sensor. Ensure the lead is positioned correctly per the image below.
_____________________________________________________________________________________________________________________________ Chest Sensor IFU Page 15 of 28 Lastly, affix the precordial (V) electrode to the patient. Placement of the electrode will determine which precordial lead is being monitored. The VMS may monitor one of the six (V1, V2, V3, V4, V5, V6) leads at a time – please see the image below for appropriate placement. Pulse Oximeter Placement Next, place the pulse oximeter at the appropriate site. The site will depend on which adapter was connected to the Chest Sensor – please refer to the corresponding section below:
_____________________________________________________________________________________________________________________________ Chest Sensor IFU Page 16 of 28 L2050F Adapter Place the pulse oximeter finger clip over a finger on the patient’s left hand (index finger preferred). Ensure that the patient’s finger reaches the back of the pulse oximeter enclosure. It is recommended to tape down the cable slack to prevent accidentally pulling or yanking of the cable. See the picture below for recommended tape sites. L2050E Adapter Place the pulse oximeter ear clip over the patient’s earlobe. Ensure that the ear clip fully covers the earlobe and is secure.

See the picture below for recommended tape sites. 3 Charging the Chest Sensor Overview The Chest Sensor uses a micro-USB connector for connecting to a charger. The charger must be connected to mains power to charge the Chest Sensor internal battery. Vios recommends using the following power supplies for charging the Chest Sensor:  TRUMPower Medical Grade Power Supply, Model TRM15-S05-E-UB-10F  ASUS Switching Power Supply, Model PSM06A-050Q Note: Please do not charge the Chest Sensor at temperatures less than or equal to 32°F. LED Indications When properly connected to a powered charger, the Chest Sensor LED will indicate a color based on the remaining battery life. See the images below for descriptions of each color representation.
_____________________________________________________________________________________________________________________________ Chest Sensor IFU Page 18 of 28 Use the battery status indication to guide your decision about whether that particular Chest Sensor should be used or not. If the Chest Sensor indicates low battery (red), please consider waiting for the Chest Sensor to fully charge or use a different, fully charged device. See the ‘Charging the Chest Sensor’ section for instructions on charging. 5 Pairing to a Bedside Monitor Overview Before pairing the Chest Sensor with a Bedside Monitor (BSM), you must initiate Bluetooth Low Energy (BLE) advertising on the Chest Sensor. Initiating Bluetooth Low Energy (BLE) Advertising To initiate Bluetooth Low Energy (BLE) Advertising, press and hold the Patient Call Button for at least seconds (4) seconds. For the first four (4) seconds, you will see the battery status indicated as described in the ‘Battery Check’ section. If you continue to hold the Patient Call Button for more than four (4) seconds, the Chest Sensor LED will begin blinking blue at a rate of once per second.
_____________________________________________________________________________________________________________________________ Chest Sensor IFU Page 19 of 28 Pairing to a Bedside Monitor (BSM) Once you have initiated Bluetooth Low Energy advertising, pair the Chest Sensor to the Bedside Monitor (BSM) using the Bedside Monitor software. For instructions on how to do this, please refer to the Bedside Monitor (BSM2050) Instructions for Use. Confirmation of Pairing After pairing the Chest Sensor to the Bedside Monitor (BSM), the Chest Sensor LED will slowly blink green (once per 10 seconds) to indicate that it is paired.
