SPC Fundamentals Unit 6 Exam 3
| Question | Answer |
|---|---|
| What is oxidation? | Electron Loss Occurs @ the anode of the E/C Analyzers Electrolyte solution supplies ions for oxidation reaction |
| What is reduction? | Electron Gain Occurs @ the cathode of the E/C Analyzers O2 is reduced forming OH- (Hydroxide Ion) |
| Polorgraphic Analyzer | Classified as electrochemical type of analyzer 0.6 volt charge is applied to the anode to drive the REDOX reactions Found in Blood Gas Machines/TCO2 monitors Ventilator circuits/Oxygen Analyzers |
| Galvanic Fuel Cell | Classified as electrochemical analyzer No voltage needed for REDOX reactions Found in Ventilator Circuits/Oxygen Analyzers |
| P/G (Polorgraphic Analyzer) Components | Silver Anode Platinum Cathode Battery KCI Electrolyte Solution Polypropylene Membrane |
| GFC (Galvanic Fuel Cell) Components | Lead Anode Gold Cathode KOH or CsOH Electrolyte Solution Teflon Membrane |
| Clinical Applications | Pressure effects readings (High ALT=low readings)(PEEP=high readings) Water vapor effects readings (low) |
| P/G Response Time | <30sec |
| GFC Response Time | Up to 60sec |
| E/C stands for? | Electrochemical |
| REDOX | Reduction-Oxidation |
