EtCO2 Anesthetized Range Checker
Actual independently measured actual anesthetized end-tidal CO2 under actual species/age/state/device/protocol-specific caller review bounds in caller verified same-unit pressure relative only to independently applicable caller bounds. Inclusive endpoints, signed margins; method, context, age/state and uncertainty must be independently established. No universal normal range, diagnosis, intervention or safe-use approval.
Description
End-tidal carbon dioxide is a capnography measurement tied to the sampled respiratory phase and instrument.
End-tidal carbon dioxide is a capnography measurement tied to the sampled respiratory phase and instrument.1
A matched pressure-range comparison does not independently assess ventilation or adjust anesthesia.
When to use EtCO2 Anesthetized Range Checker
Use this tool to compare a measurement with the supplied applicable bounds. Establish the animal, measurement protocol, units and independently applicable veterinary prescription or reference.
How to use EtCO2 Anesthetized Range Checker and understand its results
- Establish the animal, measurement protocol, units and independently applicable veterinary prescription or reference.
- Enter independentlyMeasuredValue, callerApplicableLowerValue, callerApplicableUpperValue, using the field meanings and rules below, then run the tool.
- Read withinCallerScreen. A true result includes both boundaries; inspect signedLowerMargin and signedUpperMargin to see the distance from each bound.
- 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 |
|---|---|---|---|
| independentlyMeasuredValue | Independently measured value | number | Required |
| callerApplicableLowerValue | Caller applicable lower value | number | Required |
| callerApplicableUpperValue | Caller applicable upper value | number | Required |
Enter a finite observation and independently applicable lower and upper bounds in the same units. Require lower≤upper, including equal bounds. Both endpoints pass the inclusive comparison. Return the within-bounds boolean and two signed margins; a negative margin identifies which boundary is exceeded. The implementation does not impose additional physiological ranges or choose the bounds.
within=(lower≤observed≤upper); lowerMargin=observed−lower; upperMargin=upper−observed Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observation, conditional calculation or reference | object |
| result.withinCallerScreen | True when the measurement is between the supplied bounds, endpoints included. | boolean |
| result.signedLowerMargin | Observed value minus the supplied lower bound. | number |
| result.signedUpperMargin | Supplied upper bound minus observed value. | number |

}Limitations and assumptions
The patient context, observations and applicability of any reference or prescription must be independently established. This result supplies no diagnosis, default dose, treatment selection or assessment of clinical suitability. Passing means only that the supplied measurement is inside the supplied inclusive bounds.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use SpO2 Pulse Oximeter Interpretation Tool: Pulse-oximeter SpO2 is a measured oxygen-saturation percentage subject to device and measurement context. For a complementary comparison, use Vet ECG HR QRS Interpretation Tool: An ECG review needs calibrated tracing context and qualified interpretation of observed findings.
