Starling curves and central venous pressure [PDF]
Recent studies challenge the utility of central venous pressure monitoring as a surrogate for cardiac preload. Starting with Starling's original studies on the regulation of cardiac output, this review traces the history of the experiments that elucidated the role of central venous pressure in circulatory physiology.

Optical Hemodynamic Imaging of Jugular Venous Dynamics During Altered Central Venous Pressure [PDF]
Objective: An optical imaging system is proposed for quantitatively assessing jugular venous response to altered central venous pressure. Methods: The proposed system assesses sub-surface optical absorption changes from jugular venous waveforms with a

Background: Atrial fibrillation is an arrhythmia that results from abnormal depolarization of the atrium. Atrial fibrillation occurs in 5–40% of patients with cardiovascular bypass surgery, usually occurs on 2 to 4 days postoperatively.

Isolated central venous pressure elevation caused by hematoma formation compressing the superior vena cava following a Bentall operation: a case report [PDF]
We present a case of a patient exhibiting isolated elevation of the central venous pressure with minimal hemodynamic deterioration in an immediate postoperative period after Bentall operation requiring re-exploration.

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.

Acute complete heart block in dogs [PDF]
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 ...

Lactate Clearance vs Central Venous Oxygen Saturation as Goals of Early Sepsis Therapy: A Randomized Clinical Trial [PDF]
Context Goal-directed resuscitation for severe sepsis and septic shock has been reported to reduce mortality when applied in the emergency department. Objective To test the hypothesis of noninferiority between lactate clearance and central venous oxygen

Inadvertent arterial insertion of a central venous catheter: delayed recognition with abrupt changes in pressure waveform during surgery -A case report- [PDF]
We present a case of inadvertent arterial insertion of a central venous catheter, identified during a pericardiectomy procedure after observing abrupt changes in pressure waveform and confirmed via arterial blood gas analysis and transesophageal ...

Monro-Kellie 2.0: The dynamic vascular and venous pathophysiological components of intracranial pressure [PDF]
For 200 years, the ‘closed box’ analogy of intracranial pressure (ICP) has underpinned neurosurgery and neuro-critical care. Cushing conceptualised the Monro-Kellie doctrine stating that a change in blood, brain or CSF volume resulted in reciprocal ...
