Hemoglobin Determination Using Pulse Co-Oximetry and Reduced-Volume Blood Gas Analysis in the Critically Ill: A Prospective Cohort Study [PDF]

Diagnostics, 2022
Hospital-acquired anemia is common in patients hospitalized in the intensive care unit (ICU). A major source of iatrogenic blood loss in the ICU is the withdrawal of blood for laboratory testing.

Methodology of True Pulmonary Blood Volume Determination [PDF]

Circulation, 1966
"True" pulmonary blood volume has been determined by three indicator-dilution methods in 96 subjects. In two methods a right or left ventricular mixing chamber is interposed between the injection and sampling sites while in the third such a mixing chamber is absent.

Photoplethysmographic imaging of hemodynamics and two-dimensional oximetry [PDF]

Известия Саратовского университета. Новая серия: Физика, 2022
Background and Objectives: A review of recent papers devoted to actively developing methods of photoplethysmographic imaging (PPGI) of blood volume pulsations in vessels and non-contact two-dimensional oximetry on the surface of the human body is carried

Determinants of pulmonary blood volume [PDF]

Journal of Clinical Investigation, 1970
Pulmonary blood volume was determined by the radiocardiographic technique in 49 patients coming to cardiac catheterization. Since this method has not been directly compared with the more commonly used double injection of dye. 25 comparisons were carried out in 13 patients of the series.

Intraoperative blood collection without fluid replacement for cardiac surgery – A retrospective analysis

Annals of Cardiac Anaesthesia, 2022
Background: Transfusion rates in cardiac surgery are high. Aim: To determine if intraoperative autologous blood removal without volume replacement is associated with fewer homologous blood transfusions without increasing acute kidney injury.

Applying the Optimized CO Rebreathing Method for Measuring Blood Volumes and Hemoglobin Mass in Heart Failure Patients

Frontiers in Physiology, 2018
Introduction: Determination of blood volume, red cell volume, and plasma volume contributes to the understanding of the pathophysiology in heart failure, especially concerning anemia and volume load. The optimized carbon monoxide (CO)-rebreathing method (

Assessment of postpartum haemorrhage for placenta accreta: Is measurement of myometrium thickness and dark intraplacental bands using MRI helpful?

BMC Medical Imaging, 2022
Background This study aimed to investigate the predictive values of magnetic resonance imaging (MRI) myometrial thickness grading and dark intraplacental band (DIB) volumetry for blood loss in patients with placenta accreta spectrum (PAS). Methods Images
