The phrase "Induced Cardiac Arrest" comprises four words that are pronounced as follows: [ɪnˈdjuːst kɑːˈdiːæk əˈrɛst]. The first phoneme of "induced" is [ɪ], which sounds like the "i" in "bit". The second word, "cardiac", begins with [kɑː], which is similar to the pronunciation of the letter "c". The final two words, "arrest", have the same phonemes including the stress on the second syllable [rɛst]. Collectively, this phrase refers to a medical procedure that stops the heart temporarily, often done as part of a surgery or research experiment.
Induced cardiac arrest refers to a deliberate or planned interruption of the normal electrical and mechanical activity of the heart. This procedure is typically carried out in a controlled medical setting, under the supervision of trained healthcare professionals. It involves the administration of specific medications or the delivery of electrical shocks to the heart, with the aim of temporarily stopping the heart's pumping action.
The primary purpose of inducing cardiac arrest is to facilitate medical interventions or procedures that require a motionless heart. These procedures may include open-heart surgeries, certain surgical treatments for cardiac arrhythmias, and coronary angiography. By inducing cardiac arrest, medical professionals are able to operate on a stationary and bloodless heart, enhancing the precision and safety of these procedures.
During induced cardiac arrest, the heart temporarily ceases to effectively circulate blood throughout the body. Blood flow to vital organs, including the brain, is significantly reduced or halted. To prevent severe damage or complications, artificial respiration and external mechanical devices are commonly employed to maintain oxygenation and circulation during the period of cardiac arrest.
It is important to note that, unlike sudden cardiac arrest, which can occur unexpectedly due to a heart-related emergency, induced cardiac arrest is intentionally initiated, monitored, and controlled within a medical setting for therapeutic purposes.
