Study Objectives:Abdominal obesity, particularly common in centrally obese males, may have a negative impact on upper airway (UA) function during sleep. For example, cranial displacement of the diaphragm with raised intra-abdominal pressure may reduce axial tension exerted on the UA by intrathoracic structures and increase UA ...

In patients with autonomic failure orthostatic hypotension results from an impaired capacity to increase vascular resistance during standing. This fundamental defect leads to increased downward pooling of venous blood and a consequent reduction in stroke volume and cardiac output that exaggerates the orthostatic fall in blood pressure. The location of ...

Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body plethysmography during contractions of the diaphragm and abdominal muscles. Trunk volume changes with blood shifts, but body volume ...

Superior mesenteric artery (SMA) syndrome describes vascular compression of the third portion of the duodenum and presents with nausea, postprandial vomiting, and epigastric abdominal pain. The syndrome is rare and may be missed if appropriate radiologic studies are not performed or the clinical presentation is atypical. The clinical contexts in which SMA ...

We developed a model to demonstrate how a hopping kangaroo breathes. Interestingly, a kangaroo uses less energy to breathe while hopping than while standing still. This occurs, in part, because rather than using muscle power to move air into and out of the lungs, air is pulled into (inspiration) and pushed out of (expiration) the lungs as the abdominal organs ��flop�� ...

For an arbitrary magnetostatic equilibrium, instability growth rates are shown to be an increasing function of compressibility.

It is hypothesized that in some women an excessively high intra-abdominal pressure (IAP) compresses the inferior vena cava, uterine veins, portal vein, hepatic veins, splenic vein and renal veins which lead to a decreased flow in these vascular beds, producing lower extremity edema, fetal-placental ischemia, a glomerulopathy with proteinuria and ...
