The relationship between cerebral blood flow and venous sinus pressure: can hyperemia induce idiopathic intracranial hypertension?

open access: yesFluids and Barriers of the CNS, 2021
Background It has been shown that idiopathic intracranial hypertension (IIH) in children is associated with cerebral hyperemia, which induces an increase in cerebral venous pressure.

Acute complete heart block in dogs [PDF]

open access: yes, 1955
A study has been conducted immediately and up to 18 days after the surgical production of complete heart block in dogs. Immediately after surgery cardiac output, coronary flow, and mean arterial pressure were reduced in rough proportion to the degree of ...

The efficacy of sonographic measurement of inferior vena cava diameter as an estimate of central venous pressure

open access: yesCardiovascular Ultrasound, 2015
BackgroundCentral venous pressure (CVP) and right atrial pressure (RAP) are important parameters in the complete hemodynamic assessment of a patient. Sonographic measurement of the inferior vena cava (IVC) diameter is a non-invasive method of estimating ...

Automated expiratory ventilation assistance through a small endotracheal tube can improve venous return and cardiac output

open access: yesIntensive Care Medicine Experimental, 2019
Background Positive pressure ventilation can decrease venous return and cardiac output. It is not known if expiratory ventilation assistance (EVA) through a small endotracheal tube can improve venous return and cardiac output. Results In a porcine model,

Spontaneous contractions of the human thoracic duct—Important for securing lymphatic return during positive pressure ventilation?

open access: yesPhysiological Reports, 2022
The thoracic duct is responsible for the circulatory return of most lymphatic fluid. The return is a well‐timed synergy between the pressure in the thoracic duct, venous pressure at the thoracic duct outlet, and intrathoracic pressures during respiration.

Central venous pressure and liver resection: a systematic review and meta-analysis.

open access: yesHPB, 2015
BACKGROUND A liver resection under low central venous pressure (CVP) has become standard practice; however, the benefits beyond a reduction in blood loss are not well reported.

Assessment of the peripheral microcirculation using computer-assisted venous congestion plethysmography in post-traumatic complex regional pain syndrome type I [PDF]

open access: yes, 2001
In complex regional pain syndrome type I (CRPS-I), edema of the affected limb is a common finding. Therefore, the changes in macro- and microcirculatory parameters were investigated to elucidate the underlying pathophysiology.
