Compared to many other patients who went there after surgery at about the same time as when he arrived there, he isn't recovering fast. Still too weak to talk or walk. I was told that he'd be there for another few more weeks and whether he is stronger or not, he would have to go back home. After that my mil will be all on her own to see through all his needs - which I think won't be easy for her since he can be such a difficult man. But if anything serious happens then she wouldn't be able to do anything.
At least I've been reading something more about cardiac arrests. I just read about an interesting product called the AED or Automatic External Defibrillators.
An automated external defibrillator or AED is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient, and is able to treat them through defibrillation, the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm.
It is something like a small portable shock machine to get the heart beating normally. Never thought such product even exists.
We all are hoping that he gets better and stronger. His condition is indeed worrying us. We'll just have to wait and see what happens within these few weeks.
