Dimension Vista® System V-LYTE® IMT Online Training

The (Integrated Multisensor Technology) IMT System uses ion selective electrodes to measure electrolytes in serum, plasma, and urine samples. This clinical laboratory training qualifies for continuing education units (CEU).

RAPIDComm® will send results to a hospital or laboratory information system. The hospital system is displayed in the Hospital Connections tab of the Set up Patient Sample Validation window. This option is defined at the Setup Hospital Connections window accessed from the System menu. When the Query for Patient Demographics during automatic validation option is disabled, patient demographic requests are not initiated during automatic patient sample validation. During manual validation for blood gas results, operators can request patient demographics, regardless of the option setting.  When the patient query is enabled for Blood Gas, the program queries the hospital system during both automatic and manual validation of patient results. Welcome to the Dimension Vista® System V-LYTE® IMT System Training.  The (Integrated Multisensor Technology) IMT System uses ion selective electrodes to measure electrolytes in serum, plasma, and urine samples.  Electrolytes measured by the IMT System include:   Na+   K+   Cl- Select Next to continue.    Describe basic troubleshooting steps Describe flow of V-LYTE® IMT Fluids through the system Identify components of the V-LYTE® IMT Module Identify maintenance procedures After successfully completing the course, you will be able to: Select Next to continue. Congratulations. You have completed the Dimension Vista® System V-LYTE® IMT System Online Training course. Listed below are the key points that have been presented.  Take time to review the material as needed before proceeding to the final quiz.  Overview of the V-LYTE® IMT System: What is the V-LYTE® IMT System? Integrated Multisensor Technology (IMT) allows the Dimension Vista® System to simultaneously measure Na+, K+, and Cl- concentrations in serum, plasma, and urine samples. What’s integrated? The IMT System uses a special cartridge that “integrates” four electrodes: three ion selective electrodes plus a reference electrode into a single device called the V-LYTE® Multisensor. How does it work? The IMT System uses peristaltic action to pull samples and standards through the manifold and accurately position fluids in the V-LYTE® Multisensor for measurement. What is unique? The IMT System uses an alternating air-liquid flow pattern to separates samples as well as allow the V-LYTE® Multisensor to detect when fluids cross ion selective membranes for optimal measurement. Identify components of the V-LYTE® IMT System:There are various components of the IMT Module that all work together to ensure the successful measurement of electrolytes in patient samples.    The IMT System Manifold (sample port, rotary valve, and tubing connections) The IMT Probe makes a 1:10 dilution of the sample in the sample port and the Rotary valve controls the air and fluids that enter the system. The IMT System pump uses peristaltic action to pull fluids through the system. The IMT Multisensor contains ion selective electrodes and a reference electrode that measure the electrolytes. Consumables of the IMT System include: Standard B/Salt Bridge-Used in performing a two-point calibration and provides a constant reference at the reference electrode. Standard A-Used in performing a two-point calibration, a one-point offset check during each assay and used to rinse the sample port.  V-LYTE® Diluent-Used to dilute the samples 1:10. The IMT Probe must be paused prior to replacing this fluid on the system.  If it is the only fluid replaced, it does NOT require a calibration.  V-LYTE® Multisensor-Contains the Na, K, and Cl reference electrodes. Must be replaced every 14 days of use, after 2000 samples (whichever comes first), and following an Advanced IMT cleaning. Describe the flow of V-LYTE® IMT fluids through the system: The V-LYTE® IMT System uses peristaltic action to pull fluids from the rotary valve into the V-LYTE® IMT Multisensor for testing.  Understanding and identifying how the fluids flow through the system will assist you in running the system efficiently.  Once the diluted sample (1:10 with V-LYTE® Diluent) is positioned in the sensor, the Na+, K+, and Cl- ions establish equilibrium with the electrode surface. The potential generated is proportional to the logarithm of the analyte activity in the sample.  The electrical potential generated on a sample is compared to the electrical potential generated on a standard solution. Identify maintenance procedures for the V-LYTE® IMT System:  Maintenance procedures ensure the system is clean, and operating efficiently.  This is accomplished by cleaning various components of the system to remove any dried fluid build-up and to maintain proper flow rate of the Standards and samples. Routine IMT Clean-Performed automatically each day during Off-Peak Activities Inspect and clean the IMT module-Performed during weekly maintenance Inspect the Peristaltic pump tubing-Performed during weekly maintenance Perform an Advanced IMT Clean Describe basic troubleshooting steps of the V-LYTE® IMT System: The V-LYTE® IMT System is a closed indirect system of measurement.  This requires the system to have proper fluid flow. When fluids are not flowing properly, the system will fail to calibrate.  The alert displayed in the system status area will be red and display "IMT Failed to Calibrate". This error is generated when the system attempts a calibration.  The Dimension Vista® IMT System performs a two-point automatic calibration in duplicate every 4 hours. In addition, the system will routinely perform a one-point calibration check with each sample measurement.  Auto-calibration occurs after power-on, with the changing of standards A, B/Salt Bridge, or a sensor and when the system software is reset.  Select Next to continue.
