Deepest Sympathies for your loss. If you believe the medical providers breached their standard of care, make arrangements to meet with an attorney specializing in medical malpractice to do a complete evaluation.

I'm sorry to hear about this. We can't recommend lawyers in this forum, but she can use the lawyer finder tool.

Since she was on a respirator and probably nearing her last days, damages may not justify a malpractice action but have the records and imaging studies reviewed by local malpractice counsel who will get expert to review same and opine if there was a departure from accepted standards of practice and if there was, did that departure cause injury. If the answer is yes and the injuries warrant you will have found legal representation. These cases are normally taken on a contingency basis. Use find a lawyer feature to locate local counsel.

Sorry to hear about this. Talk to a local injury lawyer about your options ASAP.
