Scary stuff. What's the context of the video?
Curious if anyone here has ever been in the clutches (or the jaws) of a demented or psychiatric patient peaking on adrenaline.
The most disturbing thing is it was allowed to get insanely out of hand, to put it mildly, and nobody was there to assist / deescalate. Possibility - help was called but had not yet arrived, or help was already responding to another incident, or there was no help who could assist.
My guess:
Understaffed psych, dementia, or elderly care facility.
Poor vetting of caregivers due to inability to retain staff (low wages, dangerous work environment which translates to an unsafe patient environment, high stress, burnout)
Working staff assigned an impossible, unsafe workload with multiple patients that can go completely nuts.
Prior to the start of the video the patient likely attacked the caregiver - a bite or death grip - and would not let go. (You can see granny has the neck of the caregiver's scrubs while continuing to go for the caregiver's face - these sorts of assaults on staff are common in these sorts of facilities)
Poorly vetted caregiver lost their sh!t - it likely wasn't just the poor character of the caregiver but a compilation of stressors that made this possible. You can see the part where she cracks...Goes from lightly telling her "You stop that" to suddenly ripping her out of the chair like a ragdoll. Wrong person in the wrong place at the wrong time.
Solution:
Proper staffing - allows a safer, manageable work environment.
Wages that retain staff and attract a larger pool of applicants allowing staff to be better vetted.
More paid vacation time.
None of the above will happen.
