Spare Respiratory Capacity

Measure spare respiratory capacity relative to corrected basal OCR.

Description

Spare respiratory capacity compares maximal and basal oxygen consumption after defining the corrected basal denominator.

Spare respiratory capacity compares maximal and basal oxygen consumption after defining the corrected basal denominator. The difference itself cancels a common non-mitochondrial background.^[1]

Measure spare respiratory capacity relative to corrected basal OCR.

When to use Spare Respiratory Capacity

Use this tool to measure spare respiratory capacity relative to corrected basal OCR.

Prepare the measured profile, formula counts, upstream model outputs or caller-defined reference criteria requested. Keep paired entries aligned and units, sample basis and preprocessing consistent.

How to use Spare Respiratory Capacity and understand its results

Prepare the measured profile, formula counts, upstream model outputs or caller-defined reference criteria requested. Keep paired entries aligned and units, sample basis and preprocessing consistent.
Enter maximalOcr, basalOcr, nonMitoOcr using the field table and calculation rules, then run the tool.
Read spareOcr, spareCapacityPercent. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
maximalOcr	Maximal ocr	number	Required
basalOcr	Basal ocr	number	Required
nonMitoOcr	Non mito ocr	number	Required

Enter finite rates with basal above non-mitochondrial and maximal at least non-mitochondrial. Return signed spare OCR and percentage; maximal below basal can yield negative spare capacity.

spare=maximal−basal; sparePercent=100 spare/(basal−nonMito)

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
spareOcr	Spare ocr	number
spareCapacityPercent	Spare capacity percent	number

Limitations and assumptions

No assay trace or drug response is processed. Baseline correction and physiological interpretation remain upstream tasks.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
