I am guessing that there was a lot more to this than is available from the video.
1) DNRs are common. As individuals many people have them. Loki used to have one in his living will until I insisted he remove it and we bought a defib.
2) Facilities in the US often have a blanket DNR policy that residents agree to.
3) The video blurp said the woman's daughter was a nurse and supported the facilities actions (sounds a lot like a DNR).
Re the good Samaritan act etc
1) It depends on the jurisdiction.
2) In US and Canada if you are following the directions of a 911 operator you are not liable.
3) If you do not take any action you are NOT liable
4) If you do not ask first and get permission (or the person is unable to respond) you do become liable.
5) If you have no training and on your own decide to do something that hurts the person, you are liable (e.g. moving someone with spinal trauma) you become liable.
6) If you have received training and follow that training you are pretty much ok
Well points 1-3 are true. Point 4 may be true in the State of New York, however it is not universally true, points 5 and 6 are true in some places but not others.
There is no general duty to rescue, Quebec is a exception to this rule, however, I'm not discussing the various exceptions to this where there is such a duty, (such as spouses). Despite Good Samaritan laws - once you start to rescue you must continue to act with reasonable care - in other words you can not start to rescue a drowning person swim out to them and then say - oh the Hell with it and - swim back to shore. If however you try to save them and they still drown you are covered. Also imminent peril
may apply (e.g. there is a car crash no leaking gas, no risk of fire - you drag the person out through the window and paralyze them) you
may be liable since there was no imminent peril.
Ontario's law which is fairly typical reads in part:
"2. (1) Despite the rules of common law, a person described in subsection (2) who voluntarily and without reasonable expectation of compensation or reward provides the services described in that subsection* is not liable for damages that result from the person’s negligence in acting or failing to act while providing the services, unless it is established that the damages were caused by the gross negligence of the person. 2001, c. 2, s. 2 (1)
* who provides emergency first aid assistance to a person who is ill, injured or unconscious as a result of an accident or other emergency, if the individual provides the assistance at the immediate scene of the accident or emergency. 2001, c. 2, s. 2 (2)."
It applies not only to a physician on their way to go skating, but also to a school teacher on their way to a hockey game.
It is worth noting that
neither New Brunswick or Nunavut have Good Samaritan laws.

Now as to this incident:
A significant factor to note is that this is an area of state (and provincial) not federal law.
In this instance the woman does not appear to have had a DNR order in effect
As many people have posted the "retirement community" had a policy of "letting you lie."
Related to the above point California apparently has an exception to their "Good Samaritan" law regarding those who are working in the capacity of their profession.
An investigation has been launched, but it does not appear there was a violation of law.
However, related to the above point, and as can be seen by this whole thread, there certainly was a loss of basic humanity.
