Targeted temperature management (TTM), previously known as therapeutic hypothermia or protective hypothermia, is an active treatment that tries to achieve and maintain a specific body temperature in a person for a specific duration of time in an effort to improve health outcomes during recovery after a period of stopped blood flow to the brain.

Most tissues and organs of the body can survive clinical death for considerable periods. Blood circulation can be stopped in the entire body below the heart for at least 30 minutes, with injury to the spinal cord being a limiting factor. [4] Detached limbs may be successfully reattached after 6 hours of no blood circulation at warm temperatures.
The cold water can cause heart attack due to severe vasoconstriction, [2] where the heart has to work harder to pump the same volume of blood throughout the arteries. For people with pre-existing cardiovascular disease, the additional workload can result in myocardial infarction and/or acute heart failure, which ultimately may lead to a cardiac ...
A 2019 study also found that disrupted sleep was more likely to cause spikes in blood pressure during the evening, as well as the day after. Chronic stress can also lead to an increased risk.
"The ultimate goal is to lower blood pressures to lower the risk of strokes, heart attacks and kidney disease," says Dr. Hoang Nguyen, MD, a board-certified interventional cardiologist at ...
Low blood pressure is initially treated with fluids along with bicarbonate to reverse metabolic acidosis (if present), if the blood pressure remains low despite fluids then further measures such as the administration of epinephrine, norepinephrine, vasopressin, or dopamine can be used to increase blood pressure.
A lower resting heart rate or slower heartbeat will fill the ventricles/heart better and allow for more of a forceful contraction of blood out to the rest of the body, says Dr. Weinberg.
Treatment of cardiogenic shock depends on the cause with the initial goals to improve blood flow to the body. If cardiogenic shock is due to a heart attack, attempts to open the heart's arteries may help. Certain medications, such as dobutamine and milrinone, improve the heart's ability to contract and can also be used. When these measures fail ...
