Pilot Evaluation Comparing Regional Distribution of Ventilation During Lung Expansion Therapy

"A study investigator will provide instruction on Incentive Spirometry procedure performance before supervised therapy and monitoring begins.~* Five minutes of eupneic ventilation EIT monitoring will occur before I.S. therapy commences.~* Study participants will be asked to take 10 deep breaths through the incentive spirometer's mouthpiece, followed by a 60 second pause.~* The 10-breath cycle will be repeated three times with respiratory therapist coaching.~* Five minutes of eupneic ventilation EIT monitoring will occur following the last I.S. lung expansion therapy breath cycle.~* Incentive Spirometry therapy and monitoring session will last about 15 minutes"

"* A study investigator will provide instruction on EzPAP® procedure performance before supervised therapy and monitoring begins. A second study investigator will perform EIT device set-up and monitoring only.~* Five minutes of eupneic ventilation EIT monitoring will occur before EzPAP® therapy commences.~* Study participants will be asked to breathe normally through the EzPAP® device's mouthpiece for 10 breaths, followed by a 60 second pause.~* The 10-breath cycle will be repeated three times with respiratory therapist coaching.~* Five minutes of eupneic ventilation EIT monitoring will occur following the last EzPAP® lung expansion therapy breath cycle.~* EzPAP® therapy and monitoring sessions will last about 15 minutes"
