Use O2 Saturation Category when you need to classify peripheral oxygen saturation as hypoxemic (below 90), borderline (90 to below 95) or normal (95 to 100). Enter SpO2 using the definitions and units below so the result can be reproduced.

SpO2

A finite measured or assumed value from 50 through 100, expressed in %.

The published tool contract uses this rule: Classify peripheral oxygen saturation as hypoxemic (below 90), borderline (90 to below 95) or normal (95 to 100).

Oxygen saturation category

The calculated oxygen saturation category.

The category is produced by fixed software thresholds. Those cutoffs may differ from a laboratory, field protocol, population, jurisdiction, or current professional guideline. SpO2 must remain between 50 and 100.

Retain the original SpO2 values and their units alongside the result. O2 Content Blood is useful when you instead need to compute arterial oxygen content from hemoglobin, saturation, and PaO2. Bleeding Time Category provides another view by helping you classify a bleeding time in minutes up to 30 as normal (<= 7), borderline (<= 15), or prolonged.

• O2 Content Blood

  Compute arterial oxygen content from hemoglobin, saturation, and PaO2.

• Bleeding Time Category

  Classify a bleeding time in minutes up to 30 as normal (<= 7), borderline (<= 15), or prolonged.

• Clotting Time Category

  Flag whether a clotting time between 30 and 600 seconds falls inside the normal range of 90 to 180 seconds inclusive.
