From researching what type of apps are needed in the world that are developed but not responsive for a smartwatch device.

I came across this app called OxyKnight, for tracking blood oxygen levels while you’re sleeping. It’s catered towards people suffering from breathing difficulties and alerts you if you’re levels drop too low.

This research inspired me to design an app similar to this but catered towards children and their parents to monitor their child’s blood oxygen levels while they’re sleeping.

KidsO2 Pediatric Oxygen Monitor

Looking at the above website encouraged me to create an interface which reassured parents when their child was sleeping giving them peace of mind knowing it would alert them if their levels got too low.

This would be targeted for children from the ages 4-11, as these ages the children have some understanding of their condition but still would need monitoring from their parents until they’re a bit older.

The app would connect to a small device fitted on the child to record their blood oxygen levels. Some of the breathing conditions, it would be useful for is COPD, sleep apnoea, CF and asthma.


How it works-Oximeter:

SpO2 is usually measured with a pulse oximeter, a device that shines light on your wrist. It works by checking how much light is absorbed by your blood vessels, using red and infrared light to tell how much oxygen is in your blood. Oxygen-rich blood absorbs more infrared light, while blood with less oxygen absorbs more red light. A sensor called a PPG sensor in devices uses this information to calculate your blood oxygen level.

This was helpful to find out how blood oxygen is measured as I don’t really know much about this subject area.
