Analysis and Monitoring of Gas Exchange
| Question | Answer |
|---|---|
| Analysis | Study or interpretation |
| laboratory analysis | refers to discrete measurements of fluids or tissue that must be removed from the body |
| lab analysis measurments are made by what? | a laboratory analyser |
| Monitoring | an ongoing process by which clinicians obtain and evaluate dynamic physiological processes in a timely manner. (over time -- trending) |
| Used to measure the FiO2 | O2 Analyser |
| Monitor | a device that provides the data to the clinician in real time |
| 2 ways of measuring blood gases | 1. invasive 2. noninvasive |
| Inasive | requires insertion of a sensor or collection device into the body |

| FiO2 can be measured in 2 ways | 1. Polarographic 2. Galvanic Cell |
| Problems with Galvanic Cell include: | Low battery Sensor Electric faiure |
| Under ideal conditions of temp.,pressure, and relative humidity, both types are accurate to within _______% of the actual concentration. | +/- 2% |
| SaO2 normal value can never reach 100%. why? | SHUNT |
| Water has a constant pH of what. | 7.0 |
| To obtain accurate results with an o2 analyser, the RT must first __________ it. | Calibrate |
| O2 analyser sensors must be exposed to two gases of different O2 concentrations. What are they? | 100% O2 and (room air) 21% |
| If the analyser fails to read 100%, the device's ______________ must be adjusted until it reads________%. | clibration; 100% |
