Incentive Spirometry Volume Training
Incentive Spirometry Volume Training is a clinical respiratory therapy designed to mimic natural sighing and encourage maximal lung expansion. It utilizes a visual feedback device to guide slow, deep inhalations, effectively preventing or reversing alveolar collapse following surgery or prolonged bed rest.
- 1Sit upright in a chair or at the edge of your bed to allow for maximum diaphragmatic excursion.
- 2Hold the incentive spirometer upright, exhale normally, and then seal your lips tightly around the mouthpiece.
- 3Inhale slowly and as deeply as possible through your mouth, keeping the flow indicator within the target 'Best' or 'Better' range.
- 4Once you reach your maximum inhaled volume, hold your breath for 3 to 5 seconds to allow air to distribute evenly throughout the lungs.
- 5Remove the mouthpiece and exhale normally, resting for a few normal breaths before repeating the process for a total of 10 repetitions.
The technique relies on Sustained Maximal Inspiration (SMI) to increase transpulmonary pressure and maximize inspiratory volumes. By performing a slow, deep inhalation followed by a brief breath hold, the user promotes the collateral ventilation of alveoli through the Pores of Kohn and encourages the even distribution of pulmonary surfactant. This mechanical expansion prevents atelectasis, improves ventilation-perfusion (V/Q) matching, enhances oxygenation, and facilitates the clearance of pulmonary secretions.
