Impact of Volume-Oriented Incentive Spirometry on Lung Volume and Peak Expiratory Flow Rate in Patients With Tracheostomy.

Abstract

Background The volume-oriented incentive spirometer is a specialized device designed to facilitate maximal inspiration, promote deep breathing exercises, and enhance lung function. The use of spirometry is challenging and not proven in patients with tracheostomy. Therefore, this study aimed to assess the impact of volume-oriented incentive spirometry on lung volume and peak expiratory flow rate (PEFR) in patients with tracheostomy. Methodology All adult patients with cuffed tracheostomy tubes with a Medical Research Council (MRC) score of more than 48 were studied. Volume-oriented incentive spirometry was performed and the PEFR was measured before and after the spirometry session. All patients underwent 28 sessions in seven days with initial few training sessions. Patient demographic information, such as age, gender, reasons for tracheostomy, MRC at the beginning of the session, volume (volume per breath, mL), and PEFR, was documented. Results Thirty patients were studied, consisting of 18 males and 12 females with initial MRC scores ranging from 48 to 60. The mean lung volume and mean PEFR at the end of seven days were 950 ± 330.9and 134.7 ± 63.3, respectively, demonstrating safety with minimal complications, including four cases of pain at the tracheostomy site, three cases of hypotension, one case of abdominal pain, and 22 cases with no reported complications. Conclusion Volume-oriented incentive spirometry improves lung volumeand PEFRin patients with a tracheostomy tube. Additionally, spirometry proved to be both feasible and effective in this patient population.
