Nuchal Cord Risk Checker
Nuchal-cord evidence review, not infer a universal cord-risk probability or delivery recommendation from a loop count. Independently established criterion columns: actual cord finding independently assessed, actual fetal assessment independently reviewed, clinically relevant context independently established, qualified clinical interpretation recorded. Unknown/missing evidence retained. Not readiness, eligibility, diagnosis, treatment, safety or compliance approval.
Description
Nuchal-cord interpretation requires the actual finding, fetal assessment and clinical context.
Nuchal-cord interpretation requires the actual finding, fetal assessment and clinical context.1
A checklist records which review elements are documented without diagnosing an outcome.
When to use Nuchal Cord Risk Checker
Use this tool to calculate or review the supplied observations under the stated rules. Establish the observation date, units, measurement context and independently applicable clinical reference or calibrated model.
How to use Nuchal Cord Risk Checker and understand its results
- Establish the observation date, units, measurement context and independently applicable clinical reference or calibrated model.
- Enter independentlyWitnessedCriterionFlags, criterionKnownFlags, using the field meanings and rules below, then run the tool.
- Read result.witnessedCriteria, result.knownMissingCriteria, result.unknownCriteria. Use the units and sign conventions below. Review unresolved records and any possible bounds separately from known results.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| independentlyWitnessedCriterionFlags | Independently witnessed criterion flags | list of number | Required |
| criterionKnownFlags | Criterion known flags; binary 1 means the matched observation is known, 0 means unknown | list of number | Required |
Enter exactly 4 independently annotated criterion flags and matched known flags in the listed order. Both lists must contain only 0 or 1. A known criterion is recorded as witnessed when its flag is 1 and missing when its flag is 0. An unknown criterion remains unknown irrespective of its placeholder flag. Return the three label lists and witnessed count; this is an evidence inventory without an overall pass, diagnosis or approval decision.
| Zero-based column | Criterion |
|---|---|
| 0 | actual cord finding independently assessed |
| 1 | actual fetal assessment independently reviewed |
| 2 | clinically relevant context independently established |
| 3 | qualified clinical interpretation recorded |
witnessed={label_i:known_i=1 and flag_i=1}; missing={label_i:known_i=1 and flag_i=0}; unknown={label_i:known_i=0} Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result; its nested fields below contain the actual calculation or selected reference | object |
| result.witnessedCriteria | Criterion labels with known flag 1 and observed flag 1 | list |
| result.knownMissingCriteria | Criterion labels with known flag 1 and observed flag 0 | list |
| result.unknownCriteria | Criterion labels with known flag 0; their observed placeholder flag does not resolve the evidence | list |

}Limitations and assumptions
Dating evidence, acquisition conditions and applicable clinical references remain independently established. The output describes supplied observations or a conditional model without diagnosing an outcome, choosing a dose or verifying clinical applicability.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use Umbilical Cord Length Normal Checker: Umbilical-cord length is interpreted in the context of the actual measurement and applicable reference. For a complementary comparison, use Fetal Viability Checker: Fetal viability requires a qualified assessment of gestational dating, fetal evidence and clinical context.
