WebWhen a peristaltic swallowing wave passes down the esophagus, “receptive relaxation” of the lower esophageal sphincter occurs ahead of the peristaltic wave, which allows easy propul- sion of the swallowed food into the stomach. Rarely, the sphincter does not relax satisfactorily, resulting in a con- dition called achalasia. In medicine, the fluid wave test or fluid thrill test is a test for ascites (free fluid in the peritoneal cavity). It is performed by having the patient (or a colleague) push their hands down on the midline of the abdomen. The examiner then taps one flank, while feeling on the other flank for the tap. The pressure on the midline prevents vibrations through the abdominal wall while the fluid allows the tap to be felt on the other side. The result is considered positive if tap can be felt on t… products liability themesWebPred 1 dňom · Coastal erosion is increasing worldwide due to the increasing frequency of extreme natural phenomena and excessive human exploitation.
