PURPOSE: The purpose of this study was to compare the efficiency and comfort of binasal cannula vs. face mask during oxygen therapy.
METHODS: Sixty hypoxemic patients with the mean age±SD of 62±13 yr (range 28-87 yr) were enrolled to this prospective study. Arterial blood gas analyses of all patients were obtained before beginning the oxygen supplementation. Hypoxemic patient first used nasal cannula or face mask. Arterial oxygen saturation was continuously monitored by a finger pulse oximeter during the treatment period ended by reaching the highest level steadily. The subject was allowed to return to his oxygen saturation level in room air before changing the device for face mask or nasal cannula for oxygen treatment. Same procedures applied in the period with the treatment by the second device. Patient’s comfort was evaluated with a questionnaire after each treatment period.
RESULTS: There was no statistically significant difference in the achieved oxygen saturations with the two devices. Binasal cannula reached more quickly than the face mask to similar oxygen levels (p=0.007). Higher degree of comfort and lower degree of dyspne, nuisance and restlessness were found with binasal cannula (p=0.0001, p=0.019, p=0.0001 and p=0.0001, respectively). Binasal cannula was the frequently preferred device for oxygen therapy by 71% of the patients.
CONCLUSION: Although the efficiency of two devices doesn’t differ remarkably, the binasal cannula can be suggested as being more comfortable and time saving way of oxygen therapy in hypoxic patients.
CLINICAL IMPLICATIONS: Oxygen therapy is ordered frequently for patients with chronic pulmonary diseases and still remains a cornerstone of modern medical practice. The results of the recent study showed that oxygen supplementation via nasal cannula appears to be more comfortable, time saving and cost-effective method of oxygen delivery in the majority of subjects when compared with face mask.
