  i-STAT EG7+ cartridge; List Number: 03P76-25;

  Approximately 7.6% of cartridges from specific i-STAT EG7+ (list number 03P76-25), i-STAT EG6+ (list number 03P77-25) and i-STAT G3+ (list number 03P78-26) cartridge lots in the U.S. marketplace may report higher than expected PCO2 and lower than expected pH results due to a manufacturing issue. A falsely high pCO2 together with a falsely low pH makes the blood gas appear as if the patient is in severe respiratory acidosis. If the clinician believes the values are real, it may trigger unnecessary or even harmful interventions such as unnecessary ventilator changes, unnecessary medications, potential harm from overcorrection, or delays in identifying true problems.

  epoc BGEM BUN Test Card (25 pk) for the epoc Blood Analysis System; Siemens Material Number (SMN): 10736515;

  Use of the affected product can result in discrepant low pH and measured Total Carbon Dioxide (mTCO2) results and corresponding calculated values in arterial, venous, and capillary patient samples. An erroneously low pH or mTCO2 reading can lead to inappropriate treatment of nonexistent acidosis (respiratory of metabolic) or missed diagnosis of alkalosis (a true high pH: respiratory or metabolic alkalosis), potentially causing harm through unnecessary interventions with the former or failure to deliver appropriate treatment with the latter.

  GEM Premier 5000 PAK, Part No. 00055360004.

  Confirmed customer complaints indicating that GEM PAKs (cartridges) for the GEM Premier 5000 may experience an increased incidence of Process Control Solution Not Detected (PCSND) errors during warm-up, including consecutive occurrences, resulting in GEM PAK ejection and requiring insertion of a new GEM PAK. iQM2 is an active quality process control program designed to provide continuous monitoring of the entire testing process. Thus, if a GEM PAK completes AutoPAK Validation following warm-up, it may remain in use. Consecutive GEM PAK ejections during warm-up may prolong turnaround times, potentially delaying results. In such cases, patient management may require reassessment once results are available. While many GEM PAKs continue to perform as intended, consecutive ejections may increase the likelihood of operational disruption, highlighting the importance of advance planning where feasible to help minimize impact.
