In this clinical investigation 35 patients under mechanical ventilation were studied. It was possible to establish the precision of two pulse oximeters of different brands. The performance of these equipments was evaluated by comparing data with the hemo-oximeter and a statistical analysis employed the student t test. Results showed that bias between oximeters reading and hemo-oximeter was similar for both instruments. Eventually critical patients may present conditions that limit the use of this technique. The study showed that the discrepancy in the results observed may be attributed to the presence of the methemoglobin and possible to anaemia associated to hipoxia.Downloads

RLAE’s authorship concept is based on the substantial contribution by each of the individuals listed as authors, mainly in terms of conceiving and planning the research project, collecting or analyzing and interpreting data, writing and critical review. Indication of authors’ names under the article title is limited to six. If more, authors are listed on the online submission form under Acknowledgements. The possibility of including more than six authors will only be examined on multicenter studies, considering the explanations presented by the authors.Including names of authors whose contribution does not fit into the above criteria cannot be justified. Those names can be included in the Acknowledgements section.
