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 |
ABG Analysis | self explanatory; interperate data or results |
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% |
