Müller's maneuver

 [mil´erz]
an effort at inhalation with a closed glottis after exhalation, used during fluoroscopic examination to cause a negative intrathoracic pressure with engorgement of intrathoracic vascular structures, which is helpful in recognizing esophageal varices, and in distinguishing vascular from nonvascular structures.

Müller's maneuver

Etymology: Johannes P. Müller
an inspiratory effort against a closed airway or glottis. The effort decreases intrapulmonary and intrathoracic pressures and expands pulmonary gas. It is used during fluoroscopic examination to help visualize esophageal varices because it also causes engorgement of intrathoracic vascular structures.

Müller's maneuver

Inspiratory effort with a closed glottis at the end of expiration. This technique is used during radiographic studies to produce negative intrathoracic pressure and cause engorgement of blood vessels, thus allowing visualization of esophageal varices.

For example, a lengthy time separation between performing the Muller's maneuver and performing the NPSG could reduce the correlation coefficient.
Upon application of Muller's maneuver, there was a total collapse of the airway at the level of the palate and a narrowing of the airway at the level of the tongue base.
