The first stage of cold water immersion syndrome, the cold shock response, includes a group of reflexes lasting under 5 min in laboratory volunteers and initiated by thermoreceptors sensing rapid skin cooling. Water has a thermal conductivity 25 times and a volume-specific heat capacity over 3000 times that of air; subsequently, surface cooling ...
Asystole (New Latin, from Greek privative a "not, without" + systolē "contraction" [1] [2]) is the absence of ventricular contractions in the context of a lethal heart arrhythmia (in contrast to an induced asystole on a cooled patient on a heart-lung machine and general anesthesia during surgery necessitating stopping the heart).
When V-tach is sustained (lasts for at least 30 seconds), inadequate blood flow to heart tissue can lead to cardiac arrest. [ 63 ] Bradyarrhythmias occur following dissociation of spontaneous electrical conduction and the mechanical function of the heart resulting in pulseless electrical activity (PEA) or through complete absence of electrical ...
Give your heart a little love this winter by taking the following precautions before you head outdoors: Dress in layers to help regulate your body temperature. It’s easy to become overheated ...
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] Irregular gasping may occur during this early time period, and is sometimes mistaken by rescuers as a sign that CPR is not necessary. [ 3 ]

Heavy snow falls in Lowville, N.Y., Thursday, Dec. 5. Two people died in upstate New York after an extreme winter storm impacted a large portion of the northeast.
ECG flatline or asystole is diagnosed when a person, who is in cardiac arrest (the heart stops beating), is experiencing the following conditions: unresponsive to stimuli, without breathing or a palpable pulse. [2] The eclectrocardiogram (ECG) test records the heart's electrical activity and will show a flat line if the heart stops beating. [2]
