Key result
Continuous pulse oximetry alarm thresholds of 80-86% SpO2 detected 63-73% of generalized convulsions and 20-28% of focal seizures, with 25-146 minutes between false alarms.
Why the study?
What are the optimal continuous pulse oximetry alarm thresholds for detecting seizures while minimizing false alarms in patients with drug-resistant epilepsy?
Observational (n=45)
What are the optimal continuous pulse oximetry alarm thresholds for detecting seizures while minimizing false alarms in patients with drug-resistant epilepsy?
Setting continuous pulse oximetry alarms at 80-86% SpO2 provides a reasonable tradeoff between seizure detection and false alarm frequency in patients with drug-resistant epilepsy.

May support SpO2 monitoring in epilepsy units; leaves open optimal thresholds and prospective validation.
Goldenholz et al. (2016) conducted an observational in Drug-resistant epilepsy (n=45). Continuous pulse oximetry (SpO2) alarm thresholds was evaluated on Seizure detection accuracy and false alarm frequency. Continuous pulse oximetry alarm thresholds of 80-86% SpO2 detected 63-73% of generalized convulsions and 20-28% of focal seizures, with 25-146 minutes between false alarms.
