Abdominal Exam IV: Acute Abdominal Pain Assessment
0 Views •
2023
Source: Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT Abdominal pain is a frequent presenting concern in both the emergency department and the office setting. Acute abdominal pain is defined as pain lasting less than seven days, while an acute abdomen refers to the abrupt onset of severe abdominal pain with features suggesting a surgically intervenable process. The differential diagnosis of acute abdominal pain is broad; thus, clinicians must have a...

Pulmonary arterial hypertension (PAH) is a disease of pulmonary arterioles that leads to their obliteration and the development of right ventricular failure. Rodent models of PAH are critical in understanding the pathophysiology of PAH. Here we demonstrate hemodynamic characterization, with right heart catheterization and echocardiography, in the mouse and rat.

Abdominal Exam II: Percussion

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Medical percussion is based on the difference in pitch between the sounds elicited by tapping on the body wall. The auditory response to tapping depends on the ease with which the body wall vibrates, and is influenced by underlying organs, strength of the stroke, and the state of the body wall. There are three main medical percussion sounds: resonance (heard over lungs), tympany (heard over...

FAQs
Elevated pressure can compress abdominal vessels and reduce venous return to the heart. It may also lower perfusion of abdominal organs, creating cardiovascular and kidney-related consequences as pressure rises. These effects explain why clinicians interpret pressure measurements alongside changes in organ function rather than treating the numerical reading as an isolated finding.
The urinary bladder provides a practical window into pressure within the abdominal cavity. Clinicians measure pressure through the bladder because its pressure can reflect conditions affecting the surrounding abdominal space. Repeated assessment can therefore help identify a rising trend and support evaluation of whether increasing pressure is contributing to organ dysfunction.
As pressure within the abdomen increases, it can restrict downward movement of the diaphragm. This limitation reduces the space available for lung expansion and can contribute to respiratory complications. Monitoring respiratory status alongside abdominal pressure helps clinicians recognize when pressure-related mechanical effects may be affecting breathing and assess whether the condition is progressing.
Abdominal hypertension describes elevated intra-abdominal pressure, whereas abdominal compartment syndrome represents a more severe clinical state in which marked pressure elevation is accompanied by new organ dysfunction. This distinction makes the patient’s clinical condition essential to interpretation. A rising measurement becomes especially concerning when it coincides with kidney, respiratory, or cardiovascular deterioration.
Monitoring is particularly relevant in critically ill patients, in whom pressure elevation may develop or recur and affect several organ systems. Repeated measurements help identify changes over time rather than relying on a single observation. This surveillance can support early recognition of progression toward abdominal compartment syndrome and guide evaluation of emerging complications.
Pressure monitoring can help clinicians connect changes in intra-abdominal conditions with kidney, respiratory, and cardiovascular findings. It supports assessment of whether rising pressure may be impairing organ perfusion, venous return, or lung expansion. The resulting information can aid targeted management and improve evaluation of patients at risk for worsening pressure-related organ dysfunction.
