Cornley BG-800 Blood Gas Analyzer

Description

Key Features and Specifications

Measured Parameters: Directly analyzes pH, pO2 (partial pressure of oxygen), pCO2 (partial pressure of carbon dioxide), K+ (potassium), Na+ (sodium), Cl- (chloride), Ca++ (ionized calcium), and Hct (hematocrit).
Calculated Parameters: Derives 16 additional parameters, including temperature-corrected values (pH(TC), pCO2(TC), pO2(TC)), TCO2 (total CO2), HCO3- (bicarbonate), BE (base excess), sO2% (oxygen saturation), tCa (total calcium), AG (anion gap), RI (respiratory index), AaDO2 (alveolar-arterial oxygen gradient), and O2 SAT (oxygen saturation).
Sample Handling: Supports whole blood (120 µL), capillary blood (35 µL for arterial samples), or plasma. Results are generated and displayed within 90 seconds, enabling fast turnaround in high-pressure clinical scenarios.
Input Parameters: Allows entry of patient-specific data such as FiO2 (fraction of inspired oxygen), patient ID, temperature, hemoglobin (Hb), blood pressure (B.P.), and barometric pressure (500–800 mmHg) via the intuitive touchscreen, integrating these into results for enhanced accuracy in critical care.
Calibration and Reagents: Features a simple, snap-in disposable calibrant cartridge containing flush solution, mixed gas and liquid calibrants, and a waste container—all in a closed system for biosafe operation. Multi-specification kits (25–2000 tests per kit) offer 9 months of room-temperature storage and up to 45 days of on-board validity, reducing waste and downtime.
User Interface and Connectivity: Equipped with a color touchscreen for easy menu navigation and multilingual support. Includes built-in printer for immediate result output, RS-232 interface for connection to laboratory information systems (LIS), and USB ports for data export. Stores patient results with integrated demographics.
Technology and Safety: Utilizes electrochemical sensors for precise measurements in a biosafe, closed-loop system that minimizes exposure to biohazards. No external gas tanks required, simplifying setup and reducing operational hazards. Automatic alerts for low reagents or errors ensure reliable performance.
Physical Specifications: Compact dimensions (400 × 574 × 344 mm) with a weight of 18 kg, making it portable and easy to integrate into lab workflows. Operates on standard AC power (100–240V) with low energy consumption.

Purpose and Applications

The BG-800 is essential for assessing acid-base balance, oxygenation status, and electrolyte levels in patients with conditions like respiratory failure, sepsis, kidney disease, or those undergoing surgery/anesthesia. By providing comprehensive blood gas profiles, it aids in ventilator management, anticoagulant therapy monitoring, and overall critical care decision-making. Its rapid results and minimal sample volume make it suitable for neonates, pediatrics, and adults in ICUs, ERs, or outpatient clinics. The analyzer’s closed-system design promotes infection control, aligning with biosafety protocols in high-volume testing environments.

Compared to more advanced models, the BG-800 offers an entry-to-mid-level solution with robust functionality at a competitive price point, ideal for facilities seeking reliable performance without complex maintenance.
