Increased Pulmonary Perfusion Worsens Ventilation-Perfusion Matching
Anesthesiology, 1993Severe exercise and administration of vasopressors may adversely affect pulmonary gas exchange in humans. The role of increases in pulmonary perfusion in worsening ventilation-perfusion (VA/Q) relationships is unclear, however, because concomitant changes in ventilation and alveolar gas composition occur.

Extracorporeal lung perfusion (ex-vivo lung perfusion)
Current Opinion in Organ Transplantation, 2016The number of patients listed for lung transplantation largely exceeds the number of available transplantable organs because of both a shortage of organ donors and a low utilization rate of lungs from those donors. A novel strategy of donor lung management, ex-vivo lung perfusion (EVLP), that keeps the organ at physiological protective conditions has ...

Evolving Trends in Machine Perfusion for Liver Transplantation.
Gastroenterology, 2019he imbalance between grafts Tavailable for transplantation and demands has moved the focus of many investigators on the search for novel strategies to rescue organs, previously considered to be unsuitable for transplantation.

Automated CT perfusion imaging for acute ischemic stroke
Neurology, 2019Recent positive trials have thrust acute cerebral perfusion imaging into the routine evaluation of acute ischemic stroke. Updated guidelines state that in patients with anterior circulation large vessel occlusions presenting beyond 6 hours from time last

Ventilation/perfusion relationships
Clinical Physiology, 1980Summary. Over the last 10 years the investigation of V̇A/Q̇ relationships has been significantly advanced as a result of the application of computer‐assisted engineering techniques to the traditional concepts and equations of gas exchange. The price paid for this increase in ability to measure V̇A/Q̇ relationships has been an increase in the ...

Transmural myocardial perfusion
Progress in Cardiovascular Diseases, 1987The predilection for subendocardial underperfusion and ischemia is great and must be considered in the management of any patient, especially if there is coronary artery disease or ventricular hypertrophy. Although the mechanisms of subendocardial ischemia remain to be fully defined, they are clearly associated with the transmural distribution of ...

Digital Perfusion Phantoms for Visual Perfusion Validation
American Journal of Roentgenology, 2012Despite the increasingly broad use of perfusion applications, we still have no generally accessible means for their verification: The common sense of perfusion maps and "bona fides" of perfusion software vendors remain the only grounds for acceptance.

Ventilation-Perfusion Scintigraphy
Emergency Medicine Clinics of North America, 1991Ventilation-perfusion scintigraphy remains an important diagnostic tool in the evaluation of patients suspected of having PE. It is important for the emergency physician to be able to use the information from a lung scan appropriately in the diagnostic management of this elusive and life-threatening disorder.
