Accepts healthy volunteers: yes
Observational model: OTHER
Time perspective: PROSPECTIVE
Sampling method: NON_PROBABILITY_SAMPLE
Study population: 52 healthy young volunteers The volunteers at the age of 18 to 30, sedentary: absence of neuromuscular and/or cardiac respiratory diseases were included, the smokers, overweight, claustrophobic or the ones with difficulty in carrying out the technic were excluded

Brief 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.

Detailed 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.

Eligibility criteria: Inclusion Criteria:

* age of 18 to 30, sedentary, absence of neuromuscular and/or cardiac respiratory diseases

Exclusion Criteria:

* the smokers, overweight, claustrophobic or the ones with difficulty in carrying out the technic

Primary outcomes:
measure: maximum inspiratory and expiratory pressures
timeFrame: 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 outcomes:
measure: modified effort perception Borg scale
timeFrame: 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.
measure: heart rate
timeFrame: 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.
measure: peripheral oxygen saturation
timeFrame: 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.
measure: systolic arterial pressure
timeFrame: 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.
measure: diastolic arterial pressure
timeFrame: 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.
