Abstract

Background: Chronic hypoxemia has deleterious effects on psychomotor function that can affect daily life. There are no clear results regarding short term therapy with low concentrations of O2 in hypoxemic patients. We seek to demonstrate, by measuring the characteristics of drawing, these effects on psychomotor function of hypoxemic patients treated with O2.<br />Methods: Eight patients (7/1) M/F, age 69.5 (9.9) yr, mean (SD) with hypoxemia (Pa O2 62.2 (6.9) mmHg) performed two drawings of pictures. Tests were performed before and after 30 min breathing with O2.<br />Results: Stroke velocity increased after O2 for the house drawing (i.e. velocity 27.6 (5.5) mm/s basal, 30.9 (7.1) mm/s with O2, mean (SD), p<0.025, Wilcoxon test). The drawing time 'down' or fraction time the pen is touching the paper during the drawing phase decreased (i.e. time down 20.7 (6.6) s basal, 17.4 (6.3) s with O2, p<0.017, Wilcoxon test).<br />Conclusions: This study shows that in patients with chronic hypoxemia, a short period of oxygen therapy produces changes in psychomotor function that can be measured by means of drawing analysis.<br /> (Copyright © 2015 Elsevier Ireland Ltd.
