I-stat portable blood analyzer in austere locations Flashcards
what device is best described as a portable blood analyzer?
I-stat
_____________testing is defined as a pathology or laboratory test that is performed at the site of clinical interaction allowing immediate decision regarding treatment.
Point-of-care (POC)
T/F One of most important environmental factors that medics must always be cognizant of are extremes in ambient temperature; exposure to extreme temperatures can render results inaccurate.
true
what lab values can I-stat measure
cardiac troponin I, electrolytes, blood gas, urea, creatinine, glucose, ionized calcium, and international normalized ratio
Test results from the i-STAT are generally available in __ minutes or less.
10
T/F Cartridges are each loaded with a sample of the patient’s urine and inserted into the bottom port of the analyzer for analysis.
False, its blood not urine
T/F I-stat cartridges must be frozen to maintain their integrity and reliability
false, refrigerated
T/F Optimal operating temperature for the i-STAT analyzer is 16—30 oC (61—86oF).
true
T/F when drawing a blood sample for an I-stat, it is recommended to have the patient pump their fist multiple times to decrease the chance of missing the vein
false
when executing a blood draw for the I-stat on a patient with IV fluids being administered you must draw blood proximal to an iv site
false
Prior to using a cartridge, it must be removed from refrigerated storage and kept at room temperature in its protective pouch for at least ___minutes.
5
T/F Liquid controls, which are injected into cartridges, verify the cartridges are producing accurate results and should be used each time a new batch of cartridges is opened.
true
i-STAT does not recommend the use of ___ cartridges for patients receiving propofol or thiopental sodium.
EC8+
when using an I-stat _________and creatine can increase creatinine measurements by 0.20—0.25 mg/dl.
Acetaminophen
T/F the I-stat device will function for 15 days with expired software
false
what is the ideal method to update an I-stat device without internet connectivity?
from another I-stat device
T/F with the I-stat The electronic simulator will fail if high relative humidity interferes with the measurements.
true
If the analyzer and simulator have been stored separately in areas where the ambient temperature differs by more than ______, allow the simulator and analyzer to stand in the same place for 30 minutes before inserting the simulator into the analyzer.
3 degrees celsius or 5 degrees F
Liquid controls used in a cartridge that measures oxygen concentration must stand at room temperature for a minimum of ___ hours before use; controls for other analytes only need to equilibrate at room temperature for ____ minutes.
4 hours, 30 minutes
