Use of the tilt test in measuring acute blood loss
Annals of Emergency Medicine, 1980We undertook to determine the accuracy of the tilt test in detecting acute blood loss. One hundred volunteers were phlebotomized a specific amount of blood (Group I, 450 cc; Group II, 1,000 cc in 500 cc increments). Orthostatic vital signs were recorded at timed intervals comparing the supine to sitting and supine to standing techniques.

Emergency Medicine Clinics of North America, 1996
Acute blood loss is a common, but often challenging, problem facing emergency physicians. Inadequate or delay in treatment can lead to morbidity or mortality. Standard classifications to quantify blood loss, as well as vital signs alone, are inadequate for guiding therapy.

Reticulated Platelets following Acute Blood Loss
British Journal of Haematology, 1969Summary. This report describes a previously unreported type of platelet released into the peripheral blood of dogs following acute blood loss. These cells display coarse, punctate condensations (reticulum) when stained supravitally with new methylene blue, and are probably analogous to reticulated erythrocytes. Both types of reticulated cells occur in

Evaluation of small acute blood loss in man
The American Journal of Surgery, 1967Abstract The accuracy and comparative results of hemoglobin, hematocrit, red cell blood count, I131 HSA blood volume, blood pressure, and pulse in one hundred human subjects with measured acute blood loss have been studied. These studies were carried out in each donor prior to, immediately after, at ten minutes, and at forty-eight hours after ...

Mechanism of the ventilatory response to acute blood loss
Respiration Physiology, 1968Abstract In unanaesthetised sheep haemorrhagic hypotension was followed by increased total and alveolar ventilation and a marked rise in the ventilation-perfusion ratio of the lung. In unanaesthetised dogs the response mainly consisted of a rise in the ventilation-perfusion ratio only.

VASODILATOR RESPONSES TO ACUTE BLOOD LOSS
Australian and New Zealand Journal of Surgery, 1987There is new evidence from experiments in conscious animals that when acute blood loss exceeds about 30% of blood volume, reflex vasoconstriction is abruptly replaced by widespread vasodilatation, and there is a precipitous fall in arterial blood pressure. This vasodilatation is associated with a decline in sympathetic vasoconstrictor drive.

TRANSFUSIONS IN ACUTE LOSS OF BLOOD
Archives of Surgery, 1929An active neurosurgical clinic in which tumors of the brain are removed daily provides an unusual opportunity to observe the effects of transfusion in patients urgently in need of blood. In the majority of these patients there is no complicating factor, i.e., no traumatic shock, sepsis, primary cardiac or vascular disease; in other words, the body is ...

Ischemic retinitis as a result of acute episodic blood loss
International Ophthalmology, 1998Acute episodic blood loss leads to a sudden change in the haemodynamics leading to a number of ocular and systemic effects. Occurrence of ischemic retinitis secondary to acute blood loss is of a very rare occurrence. This communication presents a case of infarction of the nerve fibre layer secondary to acute blood loss in a 55-year-old male.
