Effects of the Breath Stacking Technic in Healthy Individuals
- Conditions
- Hemodynamic Instability
- Registration Number
- NCT03042403
- Lead Sponsor
- Federal University of Uberlandia
- 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.

- Primary Outcome Measures
Name Time Method maximum inspiratory and expiratory pressures 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.
- Secondary Outcome Measures
Name Time Method 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. the measurement of systolic arterial pressure were assessed using an aneroid-type sphygmomanometer from the brand Lamedial Commercial
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. through a pulse oximeter
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. 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
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. the measurement of systolic arterial pressure were assessed using an aneroid-type sphygmomanometer
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. by palpation method of radial artery, of respiratory frequency by direct counting of thoracic movement
