The key to a good outcome in patients with cardiogenic shock is an organized approach, with rapid diagnosis and prompt initiation of pharmacologic therapy to maintain blood pressure and cardiac output and respiratory support, as well as reversal of the underlying cause. (medscape.com)
High flow oxygen resulting in hyperoxia also has the potential to cause significant adverse cardiovascular effects with increased systemic vascular resistance and blood pressure, decreased cardiac output and reduced coronary, cerebral and renal blood flow. (bmj.com)
In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols Q {\displaystyle Q} , Q ˙ {\displaystyle {\dot {Q}}} , or Q ˙ c {\displaystyle {\dot {Q}}_{c}} , is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured per minute). (wikipedia.org)
Because cardiac output is related to the quantity of blood delivered to various parts of the body, it is an important component of how efficiently the heart can meet the body's demands for the maintenance of adequate tissue perfusion. (wikipedia.org)
Oxygen delivery (DO2 mL/min) is the resultant of blood flow (cardiac output CO) times the blood oxygen content (CaO2). (wikipedia.org)
Mathematically this is calculated as follows: oxygen delivery = cardiac output × arterial oxygen content, giving the formula: D O 2 = C O × C a O 2 {\displaystyle D_{O2}=CO\times C_{a}O2} With a resting cardiac output of 5 L/min, a 'normal' oxygen delivery is around 1 L/min. (wikipedia.org)

Aerobic exercise gets the blood pumping, which kick-starts the physical processes that are beneficial to brain health, such as the delivery of oxygen to the brain cells and the creation of new neurons. (homecareassistancecarmichael.com)
Ordinarily, the pyruvic acid formed by glycolysis in the cytosol enters mitochondria, where it undergoes a series of oxygen-requiring reactions called aerobic respiration (described next) that produce a large amount of ATP. (thenewstandardgallery.com)

Collaborative research has touched upon HIV encephalopathy, blood-brain barrier, CNS fluid dynamics, and ocular development/ disorders. (arizona.edu)
Cut off the oxygen supply to the gut for long enough and the barrier cell lining begins to die. (trainingpeaks.com)

In 2018, the patient denied a history of serious illness and had no history of surgery, trauma, drug allergy, or blood transfusion. (biomedgrid.com)
If blood loss continues during surgery, even if intravas-cular volume is maintained, oxygen-carrying capacity will eventually fall too low to meet metabolic demands, and red cell transfusion will be required. (brainkart.com)
Awareness of acquired immuno-deficiency syndrome (AIDS) and other transfusion-related diseases has led to the desire to withhold blood transfusion until absolutely necessary. (brainkart.com)
Other criteria, such as overall medical condi-tion or likelihood of continued blood loss, may be used to modify the transfusion trigger. (brainkart.com)
Transfusion of red blood cells should be undertaken only to increase the oxygen-carrying capacity and never for volume expansion alone. (brainkart.com)

Gray skin (and its cousin, delayed capillary refill) indicates that blood flow is being diverted to vital organs rather than the skin and is a highly reliable sign that always merits concern. (bchcicu.org)
