Official title

Investigation of Efficiency of Breathing With Different Breathing Patterns in Healthy Volunteers and Patients With Respiratory Failure

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Our aim in this study is to investigate the efficiency of the breathing with different breathing patterns. Ten volunteers and twenty patients having respiratory problems will be coached on their breathing through specific masks which will provide four different breathing patterns. These patterns will be 1) Breathing in through the nose only and out through the mouth only 2) Breathing in through the mouth only and out through the nose only 3) Breathing in and out through the nose only 4) Breathing in and out through the mouth only The data obtained from volunteers and patients will be compared within and between the groups.
