The ribs and intercostal muscles filter out the expiratory sound more than the inspiratory sound. This reduces airflow through the bronchial tubes, a condition called airway obstruction, making it difficult to move air in and out of the lungs. By measuring how fast youre able to breathe out, your peak flow score can indicate whether your airways are narrowed.

The child has the following vital signs: HR 168/min, resp rate of 15/min, BP of 90/60, and a temp of 98.6 F. CAP refill is 4 sec. The expiratory flow rate depends on both air leaving the central airways during dynamic collapse as a result of the high intrathoracic pressure and the effect of high alveolar pressure, increased during the compressive phase and maintained at a high level by the contraction of the expiratory muscles. They may be seen with conditions such as pneumonia, lung fibrosis, or bronchiolitis obliterans . Wheeze - an overview | ScienceDirect Topics Inspiratory Vs Expiratory Wheezing. PDF The breathless infants - ERS-education Carbon dioxide builds up in the lungs as air gets trapped in the alveoli. Expiratory wheezing alone often indicates a mild airway obstruction. What Is The Meaning Of Inspiratory Phase? The graph below on the right shows that the obstructive changes in COPD reduce the ability to expire air, and this results in an increased residual volume.
