Desaturation without an airflow event
An oxygen drop that appears while airflow and effort channels stay unchanged.
Educational reference, not a diagnostic tool. A scored event, an elevated index and a clinical diagnosis are different things. Follow your facility’s scoring manual, notification policies and clinical protocols.
- An oxygen drop alone does not establish apnea or hypopnea.
- Assess signal quality and clinical context before scoring anything.
- Do not infer an apnea from oximetry alone.
