The ultrasound probe should move from lateral to medially, a hypoechoic mass should appear anteriorly and medially to the inferior epigastric artery during Valsalva maneuver. [8] The diagnosis of a Spigelian hernia is traditionally difficult if only given a history and physical examination . [ 9 ]
The Valsalva maneuver may help check for a dural tear following certain spinal operations, such as a microdiscectomy. An increase in intra-spinal pressure will cause cerebral spinal fluid (CSF) to leak out of the dura, causing a headache. [citation needed] The Valsalva maneuver has been associated with transient global amnesia. [17] [18] [19 ...
The hernia descends below the proximal (upper) third of the vagina in females, [2] or, according to another definition, below the pubococcygeal line (PCL). [ 3 ] [ note 1 ] According to a consensus statement by the USA, Australia and the UK, [ note 2 ] a cul-de-sac hernia / peritoneocele is defined as "a protrusion of the peritoneum between the ...
The Trendelenburg position along with the Valsalva maneuver, termed as modified-Valsalva maneuver, can also be used for the cardioversion of supraventricular tachycardia. [5] The Trendelenburg position is helpful in surgical reduction of an abdominal hernia. [6]
The patient presents with a protrusion near the neck or between the ribs. The mass becomes prominent when the patient is straining or coughing. In asymptomatic individuals, lung hernia is incidentally detected in a chest X-ray taken for another reason. [3] On physical examination, a prominence or mass is seen during Valsalva maneuver. [citation ...
Müller's maneuver: Johannes Peter Müller: pulmonology: collapsed section of airway: patient attempts to breathe in with nose and mouth closed (opposite of Valsalva maneuver) Müller's sign: Friedrich von Müller: cardiology: aortic insufficiency: Müller's sign at Who Named It? visible pulsation or bobbing of uvula: Murphy's punch sign: John ...
CSF pressure has been shown to be influenced by abrupt changes in intrathoracic pressure during coughing (which is induced by contraction of the diaphragm and abdominal wall muscles, the latter of which also increases intra-abdominal pressure), the valsalva maneuver, and communication with the vasculature (venous and arterial systems).
The position of the femoral canal medially to the femoral vein is of physiologic importance. The space of the canal allows for the expansion of the femoral vein when venous return from the lower limbs is increased or when increased intra-abdominal pressure (Valsalva maneuver) causes a temporary stasis in the venous flow.
