Simply using the ventilator artificial lung on a patient for an extended period will inevitably lead to infection. When the medication is used extensively, it becomes resistant, and ultimately many such patients die from infection, which is all too common.
Modern medicine has no means to replace all functions of the brain.
The brain's functions go far beyond thought, autonomous breathing, blood pressure regulation, or temperature regulation. Without the brain's command, it's merely a matter of minutes before the body's functional regulation becomes chaotic and dysfunctional, with other organs' functions unable to sustain for long.
Clinically, the most common scenario is when true whole brain death occurs, as is the case now with Xiao Yu, with other organs gradually presenting issues that machines cannot sustain. As doctors emphasize, money shouldn't be wasted on this matter at all.
