If the pouch has been punctured, the cartridge should not be used. Cartridges should not be returned to the refrigerator once they have been at room temperature, and should not be exposed to temperatures above 30☌ (86☏). Cartridges may be stored at room temperature (18 to 30☌ or 64 to 86☏) for 14 days. (Freezing will cause higher than expected ionized calcium results). Store the main supply of cartridges at a temperature between 2 to 8☌ (35 to 46☏). Cartridge usage and efficiency reports can be generated for management of the system.Ĭartridges are sealed in individual pouches or portion packs. Data can be stored, organized, edited, and transferred to a laboratory information system or other computer system.
#Ionized calcium istat portable
IR Links for Portable Clinical Analyzers, Downloaders and Downloader/Rechargers for the i-STAT1 Analyzers and a Philips installed server for Blood Analysis Modules allow for transmission of patient records from a widely distributed network of analyzers to the Central Data Station program.
#Ionized calcium istat plus
The i-STAT1 Analyzer is capable of using the Abbott MediSense Precision PCx or PCx Plus Blood Glucose Test Strips.Ī dedicated desktop computer with the i-STAT Central Data Station program provides the primary information management capabilities for the i-STAT System. A whole blood sample of approximately 1 to 3 drops is dispensed into the cartridge sample well, and the sample well is sealed before inserting it into the analyzer. Cartridges are also available for Celite-ACT, Kaolin-ACT, PT/INR, and Troponin I/cTnI (Table 1). Sensors for analysis of pH, PCO 2, PO 2, sodium, potassium, chloride, ionized calcium, glucose, lactate, creatinine, urea nitrogen (BUN) and hematocrit are available in a variety of panel configurations. MediSense Precision PCx or PCx Plus Glucose Test Strip: 20 secondsĪ single-use disposable cartridge contains microfabricated sensors, a calibrant solution, fluidics system, and a waste chamber. Other cartridges: typically 130 to 200 seconds PT/INR cartridge: to detection of end point – up to 300 seconds (5 min.) A MediSense ® Precision PCx ™ or PCx ™ Plus Glucose Test Strip is scanned and inserted into the i-STAT1 Analyzer and a drop of whole blood is applied to the target area of the test strip.ĪCT cartridge: to detection of end point - up to 1000 seconds (16.7 min.) When a sample-filled i-STAT cartridge is inserted into an analyzer for analysis, the analyzer automatically controls all functions of the testing cycle including fluid movement within the cartridge, calibration and continuous quality monitoring. The System consists of the following primary components:Īnalyzers can be the i-STAT Portable Clinical Analyzer, the i-STAT1 Analyzer, or the Blood Analysis Module, which is used in conjunction with the Philips Medical Systems (formerly Agilent Technologies) CMS and 24/26 Patient Monitor. The i-STAT® System incorporates comprehensive components needed to perform blood analysis at the point of care. Quality Control.Ĭalibration.Ĭlinical Significance.
Supplies and Storage Requirements.īlood Specimens. pH, calculated HCO3, K and Ca measured by two methods showed significant difference, but observed differences would not affect clinical decisions except ionized calcium.ĬONCLUSIONS: This study shows that blood gas and electrolyte analysis using the I-STAT portable device is comparable with that performed by a conventional Chiron 348 pH/blood gas/ electrolytes analyzer except ionized calcium.System Overview. RESULTS: PO2, PCO2 and Na measured with I-STAT system and Chiron 348 PH/ blood gas/ electrolytes analyzer showed no significant differences. Differences between results of two methods were analyzed by paired t-test (p<0.05). METHODS: Thirty samples from the arterial blood were simultaneously analyzed with I-STAT system and with Chiron 348 pH/blood gas/ electrolytes analyzer. We evaluated the performance of the I-STAT portable clinical analyzer for measuring blood gases (pH, PCO2, PO2) and whole blood electrolytes (sodium, potassium and ionized calcium) with reference to a conventional blood gas analyzer (Chiron 348 pH/ blood gas/electrolytes). 기존의 혈액가스분석기 (Chiron348 ph/blood gas/electrolytes analyzer)와 I - STAT 휴대용 분석기의 비교Ĭomparison of Conventional Chiron 348 pH/blood Gas/electrolytes Analyzer and i-STAT Portable Clinical Analyzerĭong Suk Chung, Jong Bun Kim, Sie Hyun Youĭepartment of Anesthesiology, College of Medicine, The Catholic University of Korea, Seoul, Korea.īACKGROUND: The development of so-called "Point-of-care" (POC) devices for blood or urine analysis has resulted in many systems that are widely used at home or at the bedside.
