To better control the oxygen levels reaching the neonate when on either CPAP, Low-Flow Nasal Cannula or High-Flow Nasal Cannula treatment, an automated system needs to closed the loop between the blood oxygen saturation levels and the O2 concentration of the inhaled air. A system that continuously monitors the SpO2 levels of the child and then controls that level within a prescribed range by continually adjusting the FiO2 levels to the child will not only off-load the attending nurses to do other vital tasks but will help maintain the child in the healthy SpO2 level for a greater percentage of the time.
The main features of this product include:
- Continual monitoring of the SpO2 from existing pulse oximeter systems
- Means of adjusting FiO2 levels through custom oxygen blender
- Closed-Loop control system maintaining appropriate control
Current Activities Include:
- Prototyping first system
- Determining approximate transfer function of typical patient
Project History:
- Project identified and supported through Children’s Hospital of Minnesota
- Fall 2009, 2-Semester Senior Design Project initiated with University of Minnesota Bio-Medical Engineering
