Cartridges: The main supply of cartridges should be kept refrigerated at 2—8°C (35—46°F). In this state, they may be used until the date shown on the cartridge pack or box. Do not allow the cartridges to freeze. Cartridges may also be stored at room temperature (18-30°C or 64-86°F) for the time frame defined on the cartridge box. For example, CG8+ cartridges may be stored at room temperature for up to 2 weeks; then they must be discarded. Cartridges should not be returned to the refrigerator once they have been warmed to room temperature, and they should not be exposed to temperatures above 30°C (86°F). If a cartridge is removed from the refrigerator, then the labeled expiration date should be crossed out and the temperature expiration date should be written on the cartridge package.

Controls: Blood gas, electrolyte, and chemistry controls should be stored at 2—8°C (35—46°F). They may also be stored at room temperature (18 to 30 °C or 64 to 86 °F), but only for up to 5 days.

Analyzer: The i-STAT analyzer (and accessories) should be stored in the hard plastic case provided in the allowance standard. The device should be protected from extremes of temperature as much as possible. The optimal operating temperature range is 16 to 30 ºC.

Electronic Simulator: Store at room temperature and protect contact pads from contamination by making sure the blue plastic cap (Figure 4) covers the contact pads when stored in its protective case after use.

DEPLOYMENT CONSIDERATIONS 

One challenge for POC testing in the deployed setting is keeping the equipment within the proper temperature range.
