RAPIDLab 348EX Blood Gas SystemDeliver reliable and economical critical care testing in low-volume settings

Get trusted results for critical analytes with ease, efficiency, and economy.


The RAPIDLab® 348EX Blood Gas System* is the cost-effective solution for smaller laboratories tasked with the challenge of performing fast-turnaround critical care tests. Fully-automated operation supports low-to-medium throughput on an easy-to-use analyzer that’s ready to generate accurate, on-demand results when clinicians need them, with a minimum of operator involvement.

  • Fast, accurate critical care results from whole blood and dialysate fluid
  • Easy-to-use design features a color touchscreen, bar-code scanner and front panel access to sensors, reagents, and waste
  • Proven Ready Sensor® technology for reliable, low maintenance operation
  • Automatic sample aspiration, calibration and washes increase workflow efficiency
  • Compact footprint fits easily in core laboratory and other testing locations
  • Advanced data management and connectivity with optional remote control and monitoring via the RAPIDComm® Data Management System

Fonctionnalités et avantages

The RAPIDLab 348EX analyzer combines proven Siemens blood gas technology with a range of next-generation system enhancements designed to streamline and simplify day-to-day operations and workflow.

  • Actionable patient test results are available in approximately 60 seconds
  • Small sample size (50 µL–95 µL) suitable for most patients
  • Analyze whole blood and dialysate fluid
  • Whole blood results: pH, pCO2, pO2 Na+, K+, Ca++/Cl-, and hematocrit
  • Dialysate results: pH, pCO2, Na+, K+, Ca++, HCO3-, and ctCO2
  • Test and report only those parameters ordered by the clinician
  • Bar-code reader, for patient/operator ID entry, can be mounted on either side and offers optional setting for continuous-on, single-handing scanning
  • Sample probe aspirates from syringes, capillaries, and QC ampules automatically, without the need for adapters
  • Automatic detection of short samples shifts analyzer into microsample mode, with no operator involvement required
  • Time-tested Ready Sensor® electrodes have a proven track record of performance and long use-life
  • Comprehensive QC materials help verify system performance
  • Automatic calibration routines and wash sequences minimize demands on operators time and attention
  • Intuitive, color, touch screen user interface features large, easy-to-read system icons that display analyzer status
  • One-touch icon selection of sampling mode - syringe, capillary, dialysis fluid, QC
  • Easy navigation to all routine functions from the Ready screen
  • Measurement chamber houses all sensors and is designed for easy access and replacement
  • All reagents are located on the front panel of the analyzer, enabling easy reagent replacement
  • Clear plastic bottles and blue-colored solutions allow at-a-glance checks of fill volumes
  • Minimal maintenance requirements further extend system uptime
  • Economically priced – low cost of acquisition
  • Low operating costs – cost of reagents/consumables will not vary significantly, even if throughput triples from five to 15 samples/day
  • Small footprint saves valuable bench space in smaller labs and point-of-care settings
  • Results can be viewed on-screen, output to the onboard printer, or electronically transmitted to LIS/HIS or RAPIDComm® Data Management System
  • Convenient onboard storage of up to 250 patient test records, and up to 90 results for each level of QC
  • Print calibration and QC summaries for inspection purposes including off-line generated Levey-Jennings reports to document QC performance
  • USB port simplifies data uploads/downloads

When analyzers in remote, decentralized settings are supported by the RAPIDComm Data Management System, point-of-care coordinators can oversee the entire testing process from a central location.

  • Configure, monitor, and control multiple networked RAPIDLab 348EX analyzers
  • Troubleshoot analyzers, standardize test protocols, authorize and certify operators, and enforce QC checks
  • Generate customized reports for accreditation inspections
  • Help ensure testing and regulatory compliance, and improve risk management
  • Connect multiple Siemens point-of-care analyzers – including blood gas, urine chemistry, and diabetes care systems -- through a single interface to the LIS/HIS
