Patient Evaluation
Oximetry
| Question | Answer |
|---|---|
| Oximetry Noninvasive Method/Pulse Oximetry/Defined | -most appropriate noninvasive technique for continuous monitoring of oxygen saturation(Sp02)and pulse. |
| Oximetry Noninvasive Method/Pulse Oximetry/Normal Range | - normal range = 93-97% |
| Oximetry Noninvasive Method/Pulse Oximetry/Equipment | - probe attaches to finger and transmits light pulses through the capillary beds. |
| Oximetry Noninvasive Method/Pulse Oximetry/Troubleshoot | - if there is a sudden fall in readings without a change in the patients condition then there is a possible malfunction of the probe.= probe needs to be changed. |
| Oximetry Noninvasive Method/Pulse Oximetry/Saturation | - displayed saturations from pulse oximeters are accurate in patients with good perfusion and saturation of 70%or higher |
| Oximetry Noninvasive Method/Pulse Oximetry/Recommended | - recommended for monitoring during sleep studies - evaluating resting and exercise desaturation |
| Oximetry Noninvasive Method/Pulse Oximetry/Accuracy | - accuracy affected by perfusion(shock and hypotension) - conditions that interfere with light(erythema, bright ambient lights |
| Oximetry Noninvasive Method/Pulse Oximetry/Readings | - pulse oximeters will read higher saturation if carbon monoxide is present. |
| Oximetry Overnight Pulse Oximetry/Describe | - - assessment of oxygen saturation during an overnight period through the use of pulse oximetry. |
| Oximetry Overnight Pulse Oximetry/Indications | - as a screening tool for identifying patients with sleep related breathing disorders. - to asses response to treatment for obstructive sleep apnea. |
| Oximetry Overnight Pulse Oximetry/Invasive/Co-Oximeter/Hemoximeter | - used to diagnose carbon monoxide poison (>20% COHb) |
| Oximetry Overnight Pulse Oximetry/Invasive/Co-Oximeter/Hemoximeter Normal | - normal COHb = 1-3% - smokers COHb = 5-10% - heavy smokers = 10-15% |
| Oximetry Overnight Pulse Oximetry/Invasive/Co-Oximeter/Hemoximeter | - best method to evaluate oxygenation in patient with CO poisoning |
| Oximetry Overnight Pulse Oximetry/Invasive/Co-Oximeter/Setup | - works like pulse ox, except that a blood sample and more wave-lengths are used instead. |
| Oximetry Overnight Pulse Oximetry/Invasive/Co-Oximeter/Hemoximeter/Accurate Measurements | - more accurate measures COHb, O2Hb, and other non-functional hemoglobin (MetHb) |
