The lack of clinical relevance for the severity of dry nose with nonhumidified oxygen and the improvement reported by patients over three days with other symptoms/problems whether oxygen therapy was humidified or not suggests guidelines for clinicians. We recommend nonhumidification for short term low flow oxygen therapy (ie, up to three days). However, when oxygen therapy is ordered, patients should be assessed individually for their propensity for dry nose and nosebleed and, based on this assessment, clinicians may elect to order humidified oxygen for individual patients.
Findings from this study do not support continuation of routine humidification with low flow oxygen therapy on the basis of improved patient comfort and presumed improvement in their subjective symptoms because most symptoms/problems were not alleviated by oxygen humidifica-tion. Some may argue that further research is needed to address other possible effects achieved with humidified oxygen administration before established therapies are jettisoned. For example, investigations have been suggested to determine the effect of humidified oxygen on the rate of recovery for patients with chest disease , on its effect on asthmatics and on its relationship to patient outcomes (eg, length of stay and infection rates). Others would question the need for additional evidence to continue a therapy with unproven benefit. We recognize that further studies would allow comparison of the effects of humidified and nonhumidified oxygen therapy on the symptoms of patients in similar diagnostic categories according to severity of illness.
