mother suffering from heart attack

My mother, who came to visit us, was about to travel back to India today, but destiny had it another plans. She complained on chest pain and was admitted to Blacktown hospital who confirmed that it is cardiac arrest. They immediately transferred her to Westmead hospital for further treatment.  Her all three main arteries are found blocked and will need a bypass surgery with in this week after her condition is bit more stable. This will be followed by her care in the hospital.  
Unfortunately, the medical insurance is not covering the expenses & all our savings are already gone in her treatment until now. I request you all please help in this hard phase of our life. If you can help in any way we would all be most grateful for your help.
