Application advancements of ultrasound in assessment of diaphragmatic function in chronic obstructive pulmonary disease patients / 中国医学影像技术

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is a progressive disease characterized by persistent restricted airflow. Systemic inflammation and hyperventilation can cause diaphragmatic dysfunction. Conventional assessment methods of diaphragmatic function are invasive and lack of specificity. Recently, as a simple, noninvasive method of quantification of diaphragm contractile activity,ultrasound has attracted great attention. The progresses of ultrasound methods and application for assessing diaphragm function of patients with COPD were reviewed in this article.
