Deep hypothermic circulatory arrest (DHCA) is a surgical technique in which the temperature of the body falls significantly (between 20 °C (68 °F) to 25 °C (77 °F)) and blood circulation is stopped for up to one hour. It is used when blood circulation to the brain must be stopped because of delicate surgery within the brain, or because of ...
EPR uses hypothermia, drugs, and fluids to "buy time" for resuscitative surgery. If successful, EPR may someday be deployed in the field so that paramedics can suspend and preserve patients for transport. EPR is similar to deep hypothermic circulatory arrest (DHCA) in that hypothermia is induced. However, the purposes and procedures of EPR ...
With the advent of these strategies, cardiac arrest came to be called clinical death rather than simply death, to reflect the possibility of post-arrest resuscitation. At the onset of clinical death, consciousness is lost within several seconds, and in dogs, measurable brain activity has been measured to stop within 20 to 40 seconds. [ 2 ]
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.

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 arrest. A vagal response to an extreme stimulus as this one, may, in very rare cases, render per se a cardiac arrest. Hypothermia and extreme stress can both ...
Symptoms can last from a few hours to a few days; During rewarming, skin appears pale blue and continue to be cold, numb, and swollen [4] [15] Increased blood flow to affected tissue . Symptoms can last from a few days to several weeks; Affected limb becomes red and swollen with bounding pulses
In the 1980s, the use of hypothermia on dogs after cardiac arrest demonstrated positive outcomes, including neurological status and survival. In 2005, the American Heart Association implemented recommendations and guidelines for mild hypothermia in post-resuscitation support after cardiac arrest with return of spontaneous circulation. [2]
Like CPR, suspended animation could delay the onset of cell death (necrosis) in seriously injured or ill patients, providing them with more time to receive definitive medical treatment. Suspended animation is the temporary (short- or long-term) slowing or stopping of biological function so that physiological capabilities are preserved.
