This makes Nurse Ratched look compassionate.

A group of nurses at Medford Multicare Center on Long Island, N.Y. allegedly ignored for 24 minutes a warning light and buzzer that indicated the ventilator for quadriplegic Robert Knowles had become dislodged, a lawsuit charges.

The resulting oxygen deprivation left Knowles with severe brain damage and a seizure disorder, his family alleges in a lawsuit filed in Suffolk County Supreme Court in May 2009.

Shocking video images from a surveillance camera shows staffers fiddling around while a square light on a computer screen blinks away, according to sources who viewed it. That light goes off whenever a patient's ventilator is accidentally disconnected.

The state Attorney General's Office is investigating the March 21, 2009, incident.
