What is the Valsalva Maneuver? What Does It Do?


The Valsalva maneuver is a well-known and versatile physiological response that has intrigued scientists, healthcare professionals, and researchers for centuries. Named after the 17th-century Italian anatomist Antonio Maria Valsalva, this maneuver involves a specific pattern of forced exhalation against a closed airway, followed by relaxation. In this comprehensive scientific article, we will explore the intricacies of the Valsalva maneuver, including its mechanisms, various applications in medicine and daily life, and the physiological implications associated with its use.
