distension of pulmonary vascular bed causes tachypnoea: Chvostek sign: František Chvostek: endocrinology: hypocalcemia: tapping over facial nerve elicits abnormal muscle contraction(s) Claybrook sign: Edwin Claybrook: emergency medicine, surgery: blunt abdominal trauma: heart and/or breath sounds heard through abdominal wall indicate rupture ...
Cannon A wave. Cannon A waves, or cannon atrial waves, are waves seen occasionally in the jugular vein of humans with certain cardiac arrhythmias.When the atria and ventricles happen to contract simultaneously, the right atrium contracts against a closed tricuspid valve, resulting in back pressure into the venous system that can be seen in the jugular venous pulse as a high-amplitude "cannon ...
The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization of the internal jugular vein. It can be useful in the differentiation of different forms of heart and lung disease .
The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...
Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity.The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
An abdominal examination is a portion of the physical examination which a physician or nurse uses to clinically observe the abdomen of a patient for signs of disease. The abdominal examination is conventionally split into four different stages: first, inspection of the patient and the visible characteristics of their abdomen.
Müller's sign is the pulsation or bobbing of the uvula that occurs during systole. [1] It can be seen in patients with severe aortic insufficiency. Müller's sign is caused by an increased stroke volume. [citation needed] Müller's sign is named for Friedrich von Müller, a German physician. [citation needed]
A pulse pressure is considered abnormally low if it is less than 25% of the systolic value. [2] If the pulse pressure is extremely low, i.e. 25 mmHg or less, it may indicate low stroke volume, as in congestive heart failure. [3] The most common cause of a low (narrow) pulse pressure is a drop in left ventricular stroke volume.
