Critical Care Suite with Enteric Tube Positioning AI Algorithm

Evidence summary

The FDA clinical ground-truth study used 954 independent images from five sites across North America and the United Kingdom, spanning neonates to patients over 65 years, both chest and abdominal images, multiple tube types, varied image quality, and at least eight vendors. Five expert annotators performed two reads with arbitration. The packet reports enteric-tube detection sensitivity 0.992 (0.982, 0.997) and specificity 0.975 (0.947, 0.991); tube-tip sensitivity 0.957 (0.935, 0.973) and specificity 0.941 (0.901, 0.968); side-port sensitivity 0.931 (0.904, 0.952) and specificity 0.859 (0.801, 0.905); tube Dice 0.911 (0.912, 0.921), airway Dice 0.741 (0.730, 0.753), diaphragm Dice 0.821 (0.808, 0.834), and mean localization errors of 1.789 mm for the tube tip and 2.575 mm for the side port.

Postmarket safety review

The exact-identifier FDA recall query returned no native recall record for K253502. This limited result does not establish absence of recalls or other safety information and does not cover later versions, family records, MAUDE reports, corrections, or field notices.

• Verify deployment and data flow: The reviewed sources do not establish the current exact-release hosting topology, data flow, region, tenancy, or disaster-recovery configuration.
• Verify security and privacy controls: Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.
• Verify training: Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.
• Verify pricing and total cost: No public price or quote for the exact K253502 configuration was established in this review.
• Verify reimbursement and coding relevance: No exact-product payer policy, coding instruction, or payment determination was established; eligibility must be evaluated by payer, site of service, and use case.
• Verify local validation and lifecycle monitoring: Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.

Exact-submission ACR model-card fields were normalized under the current provenance rules; vendor and independent-study confirmation remain distinct. Exact FDA scope controls clinical claims. ACR provides bounded exact-submission catalog context. Candidate literature metadata remains a discovery queue until full-text identity, endpoint, population, and version review is completed. Automated exact-name discovery found 0 PubMed and 0 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.

Candidate leads remain unpublished until a human confirms the exact product and tested version.
