简要总结
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.
详细描述
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.

结局指标
主要结局
maximum inspiratory and expiratory pressures
时间窗: 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.
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.
次要结局
- diastolic arterial pressure(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.)
- peripheral oxygen saturation(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.)
- modified effort perception Borg scale(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.)
- systolic arterial pressure(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.)
- heart rate(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.)
