New Oxygenation Method Based on Pulse Oximeter

Abstract

The body's need of o xygen is certainbecause of its necessity to make energy fro m the food. Lungs deliver oxygen to the blood and if it cannot get enough oxygen to the blood, the patient feels short of breath, which is very uncomfortable. In this state, o xygen therapy can be help ful. Blood gas measurement provides vital information about oxygenation, ventilation and acid-base status. However, these measurements only provide a snapshot of the patient's condition taken at the time that blood sample was drawn. Oxygen level can change very quickly. In the absence of continuous oxygenation monitoring, these changes may go undetected until it is too late. In this paper, we present a new method of online oxygenation, which, could g ive o xygen to the patient with high accuracy and solve many problems involved in other methods. Ten patients ; five COPD and five patients suffer of asthmawere examined with this new method of oxygenation. None of the patients exh ibited signs of oxygen to xicity during new method of o xygen therapy. Experimental results show the acceptability of new o xygenation method in examined subjects.
