Used in point-of-care and laboratory settings by clinical staff. Employs electrochemical sensors (potentiometric, amperometric, conductimetric) to convert analyte concentrations into electrical signals. System processes signals to provide quantitative analyte values. Output used by clinicians for diagnostic assessment of patient metabolic and respiratory status. ## Clinical Evidence No clinical data provided; device relies on electrochemical sensor performance characteristics. ## Technological Characteristics Electrochemical sensor system. Potentiometric method for pH, Na+, K+, Ca2+, and pCO2; amperometric method for pO2; conductimetric method for hematocrit. Reference electrode uses silver/silver chloride in potassium chloride. Bench-top analyzer form factor. ## Regulatory Identification A blood gases (PCO2 , PO2 ) and blood pH test system is a device intended to measure certain gases in blood, serum, plasma or pH of blood, serum, and plasma. Measurements of blood gases (PCO2 , PO2 ) and blood pH are used in the diagnosis and treatment of life-threatening acid-base disturbances. ## Predicate Devices - Model 850 Analyzer ([K933373](/device/K933373.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Device Description The 348 Series system analyzer is a point of care and laboratory testing analyzer used for the direct measure of whole blood samples for the determination of the following parameters: - partial pressures of carbon dioxide; $p\mathrm{CO}_{2}$ - partial pressure of oxygen $p\mathrm{O}_{2}$ Ciba Corning 400 System 4/18/96 Page 2 {1} Company Confidential - pH - sodium; Na⁺ - potassium; K⁺ - ionized calcium; Ca²⁺ - hematocrit; Hct ## 3. Statement of Intended Use The Ciba Corning 348 System is intended for the point-of-care and laboratory testing of blood gases, electrolytes and metabolites in arterial, venous and capillary whole blood samples. ## 4. Summary of Technological Characteristics The 348 Series System uses measurement technology that is based on electrochemical phenomena. The device uses potentiometry, amperometry and conductimetric methods to convert the potential generated by the sensor to an electrical signal which the system then converts to a value that represents that concentration of a specific analyte in the whole blood sample. The 348 Series sensors (i.e., electrodes) provide direct measurement of the specific analytes or substances in the sample. Each sensor in the 348 system is highly selective for one substance over others. The sensors use the following measurement technology: | Sensor | Measurement Technology | | --- | --- | | | | | pH, Na⁺, K⁺, Ca²⁺, | potentiometric method using ion-selective electrode technology | | reference | silver electrode in potassium chloride and silver chloride | | pCO₂ | potentiometric method | | pO₂ | amperometric method | | hematocrit | conductimetric method | Ciba Corning 400 System 4/18/96 Page 3 --- **Source:** [https://fda.innolitics.com/submissions/CH/subpart-b%E2%80%94clinical-chemistry-test-systems/CHL/K962021](https://fda.innolitics.com/submissions/CH/subpart-b%E2%80%94clinical-chemistry-test-systems/CHL/K962021) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
