The symptoms of TACO can include shortness of breath , low blood oxygen levels , leg swelling (peripheral edema), high blood pressure (hypertension), and a high heart rate (tachycardia). [ 3 ] It can occur due to a rapid transfusion of a large volume of blood but can also occur during a single red blood cell transfusion (about 15% of cases). [ 2 ]
The Bainbridge reflex (or Bainbridge effect or atrial reflex) is a cardiovascular reflex causing an increase in heart rate in response to increased stretching of the wall of the right atrium and/or the inferior vena cava as a result of increased venous filling (i.e., increased preload).
When the rate of blood flow becomes too rapid, or fast blood flow passes on damaged endothelium, it increases the friction within vessels resulting in turbulence and other disturbances. [3] According to the Virchow's triad , this is one of the three conditions (along with hypercoagulability and endothelial injury/dysfunction ) that can lead to ...

After the study, the almond-eating group had greater amounts of antioxidants in the blood, better blood flow and lower blood pressure. In addition to almonds, pistachio and walnut consumption has ...
When resulting from blood loss, trauma is the most common root cause, but severe blood loss can also happen in various body systems without clear traumatic injury. [3] The body in hypovolemic shock prioritizes getting oxygen to the brain and heart, which reduces blood flow to nonvital organs and extremities, causing them to grow cold, look ...
The risk of a transient catastrophic cardiac event increases in individuals with heart disease during and immediately after exercise. [71] The lifetime and acute risks of cardiac arrest are decreased in people with heart disease who perform regular exercise, perhaps suggesting the benefits of exercise outweigh the risks.
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system. Initial symptoms of shock may include weakness, tachycardia, hyperventilation, sweating, anxiety, and increased thirst. [1] This may be followed by confusion, unconsciousness, or cardiac arrest, as complications worsen. [1]
