Clinical Trial Summary

This study aims to Analyze and compere the hemodynamic and respiratory variables before, during and after the applying of technic as well as evaluate respiratory pressures generated during applying of this same technic and correlate them with the effort noticed by device user.

Description:

The breath stacking technic (BS) is an inspiratory maneuver used for recruitment of collapsed alveoli and, consequently, improves oxygenation and, therefore, used by respiratory physiotherapy aiming promoting lung re-expansion being. The BS was described by Marini as an attempt of optimizing vital capacity in little co-operative individuals and hemodynamics has been considered a way of incentive spirometry that provides high lung volume, in situations, in which, inspiratory maneuver duration can be as important as the volume reached, composing an alternative incentive of inspiration technic4. The system used is composed by an interface (facial mask) connected to the patient, an inspiratory unidirectional valve and the respiratory branch which is kept occluded during the carrying out of maneuvers.

Intervention

Other:
• Breath stacking
During initial rest period, the volunteer remained seated for 10' in spontaneous breathing. Right after, the measurement of arterial pressure, of SpO2 (%), of heart rate, of respiratory frequency and applied to a modified effort perception Borg. During carrying out of the breath stacking technic, the volunteer remained seated, being requested to hold the mask on his/her face not allowing air scape, The volunteer was oriented to inhale normally and exhale all the air during expiration for 20 seconds, and the variables were assessement again the same variables of control. In the final rest period, right after technic end, the volunteers remained seated for 10 minutes in spontaneous breathing and again the same variables of control at the 10th minute were assessed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	maximum inspiratory and expiratory pressures	connected to a manometer from brand Commercial Medica (Brazil) used to measure maximum inspiratory and expiratory pressures generated during carrying out of technic. The volunteer was oriented to inhale normally and exhale all the air during expiration for 20 seconds.	During the intervention. They will be used to verify the average pressures generated during the execution of the technique. Time of the technique equal to 20 seconds.
Secondary	modified effort perception Borg scale	applied to a modified effort perception Borg scale with a score from 0 to 10, considering 0 the smallest effort noticed and 10 the biggest effort reported	Before, during and after the intervention. They will be used to compare the variation before, during and after the technique. Valuation time was 1 minute.
Secondary	heart rate	by palpation method of radial artery, of respiratory frequency by direct counting of thoracic movement	Before, during and after the intervention. They will be used to compare the variation before, during and after the technique. Valuation time was 1 minute.
Secondary	peripheral oxygen saturation	through a pulse oximeter	Before, during and after the intervention. They will be used to compare the variation before, during and after the technique. Valuation time was 1 minute.
Secondary	systolic arterial pressure	the measurement of systolic arterial pressure were assessed using an aneroid-type sphygmomanometer	Before, during and after the intervention. They will be used to compare the variation before, during and after the technique. Valuation time was 1 minute.
Secondary	diastolic arterial pressure	the measurement of systolic arterial pressure were assessed using an aneroid-type sphygmomanometer from the brand Lamedial Commercial	Before, during and after the intervention. They will be used to compare the variation before, during and after the technique. Valuation time was 1 minute.
