Respiratory Support and Mechanisms

TInspiration boosting techniques were proposed in order to promote sustained maximal inspirations, creating high ventilation pressures and preventing alveolar collapse. Incentive spirometers are classified as volume-dependent or flow-dependent, possessing visual biofeedback mechanism and requiring patient cooperation for the effectiveness of the technique. An alternative mechanism for inspiration boosting that can be used with uncooperative individuals is called breath-stacking. This review aims to collate the current knowledge about volume or flow-dependent incentive spirometers and the breath-stacking technique, comparing the different incentive spirometers to one another to the breath-stacking technique. The volumedependent incentive spirometers have advantages with regard to providing lower respiratory rate, smaller tidal volume, larger displacement of the abdominal compartment, and less additional work of breathing in relation to flow-dependent incentive spirometers. In comparison with incentive spirometers, the breath-stacking technique achieves better inspiratory capacity and longer lung expansion. Furthermore, breath-stacking has the advantage of not depending on the individual’s cooperation Inspiration boosters: technical updates in incentive spirometers and breath-stacking Ingrid de Castro Bolina Faria1, Lincoln Marcelo Silveira Freire (in memoriam)2, Walkyria N Oliveira Sampaio3 1 Professora do Centro Universitario de Belo Horizonte.
