Abstract

It is already established that low flow oxygen therapy is beneficial to the hypoxemic patients who need oxygen. With development of non-invasive oxygen monitoring system such as pulse oximetry, variable oxygen monitoring studies were tried. One of those studies, we recently designed a modified oxygen cannula to improve oxygen effect with lower cost of oxygen therapy. We compared oxygen saturation using conventional nasal catheter (A), standard nasal cannula (B and C) and modified nasal cannula (D) at 1 through 3 L/min Under the same flow of oxygen, the level of SaO₂ by oxmetry, are not signicant in defferent type of oxygen supplier. With newly modified type D cannula there are significant changes of SaO₂ rather than type C cannula at flow of 2-3 L/ min of oxygen (P < 0.05). The mean improvement in oxygen saturation using type D vs the type C was 1 % at 2 L/ min However, when the modified nasal cannula was compared with the conventional nasal cannula (type B) and the nasal catheter, SaO₂levels were not significantly different at flow rates 1.0, 2.0 and 3.0 L/ min. There was a very good correlation between SaO₂ levels measured by ear oximeter and SaO₂ measured by ABG (r=0.97).
