Randomized double-blind trial of the effects of humidified: DISCUSSION (4)

Although replication of this study with a larger sample would confirm or refute present study findings, larger studies are difficult to justify based on anticipated cost savings. Consequently, we recommend that patient outcomes be monitored with routine short term nonhumidified Read More

Randomized double-blind trial of the effects of humidified: DISCUSSION (3)

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 Read More

Randomized double-blind trial of the effects of humidified: PATIENTS AND METHODS (3)

The questionnaire used for data collection was based in part on information described by Campbell et al and on the clinical expertise of the co-investigators. After being critiqued by university-based experts in medicine, nursing and educational psychology, the questionnaire was Read More

Randomized double-blind trial of the effects of humidified: PATIENTS AND METHODS (2)

Procedure: Only the respiratory therapist commencing the oxygen administration knew of the patient’s random assignment to group. Patients received oxygen using two flowmeters attached to a duplex outlet. Only one flowmeter was attached to a humidification bottle so that randomization Read More

Randomized double-blind trial of the effects of humidified: PATIENTS AND METHODS (1)

A randomized double-blind experimental study design was used. The independent variable was the method of low flow oxygen administration. The treatment group received nonhumidified oxygen whereas the control group received humidified oxygen according to standard hospital practice. Dependent variables included Read More
