Automatic Control for Oxygen Intake via Nasal Cannula

摘要

In the present oxygen supplying using nasal cannula is the first aide for a patient who has the problems in respiratory system by example in a newborn baby in which the incompetence of respiratory system on early days of birth is concerned. An indicator of this kind of symptom is physiological Jaundice, yellowish discoloration of the skin. Direct oxygen intake is a usual caretaking for this group of patients. Basically manual valve control of feeding oxygen by caretaker is a treatment by using pulse oximetry value as monitoring of effectiveness. This treatment is either time or labor consuming in a corona care unit. The purpose of this research is to develop an automatic control for oxygen intake. By studying the mechanism of arterial oxygen saturation in blood (SaO_2) under the partial pressure of feeding oxygen (PiO_2), the effective model can be applied as control value of oxygen for this group of patient.
