| Auscultation of the lungs revealed inspiratory crackles in the lower lung zones. |
| Thus, in patients with severe airway obstruction, inspiratory muscle fatigue may limit exercise performance. |
| Flow demand was estimated from mean inspiratory flow on continuous positive airway pressure. |
| The flow rate of fixed concentration masks should be adjusted for patients with high peak inspiratory flows. |
| Chest examination revealed fine late inspiratory crackles with otherwise normal breath sounds. |
| This could make the inspiratory muscles vulnerable to the development of muscle fatigue. |
