Measure
Volumetric Incentive Spirometry
Incentive Spirometry Volumetric Incentive Spirometry: 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
EzPAP® POSITIVE AIRWAY PRESSURE
EzPAP EzPAP® POSITIVE AIRWAY PRESSURE: - 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
