Why is “data retention” more important than a one-time measurement?
A single blood oxygen value can reflect the current state, but it cannot reveal long-term trends. For patients with chronic conditions, continuous monitoring data is essential to help them understand their real health status. For example:
1. Is blood oxygen gradually declining?
2. Are there intermittent drops in oxygen saturation during sleep?
Such questions cannot be answered by a single reading.
Modern handheld pulse oximeters can transmit data to mobile phones or management platforms in various ways, enabling:
1. Automatic recording of historical data, making it easier for doctors to evaluate when needed;
2. Integration with health record systems to support long-term follow-up management.
