Monitoring a pulse oximeter with InfluxDB is a method used by Mike Hinkle, a parent, to track his daughter's health in real-time. He uses time-stamped data stored in InfluxDB to analyze trends and patterns in her oxygen levels and heart rate. This allows him to better understand her health status and identify potential issues before they become severe. With the help of Grafana, Mike can visualize the data and create dashboards that provide valuable insights into his daughter's condition. Additionally, he is exploring environmental factors such as barometric pressure, temperature, and humidity that may impact his daughter's health, with the goal of identifying correlations between these variables and her oxygen levels or heart rate. By using InfluxDB to collect and analyze data, Mike aims to improve his daughter's treatment and provide more effective care for her hydrocephalus and VP shunt.
