What does it actually monitor?
From the company's web site:
Lively pillbox activity sensors monitor daily medication activity and
create an alert whenever anything is missed
They also have a web based dashboard, which relatives or carers can check.
Lively's safety watch features a pedometer to keep track of steps throughout
the day.

From a USA Today review
When you're out of range, the watch reminds the person to call 911
Specifically I would like to know, does it check the vulnerable
person's pulse or neural activity, or is it just checking for various
motions/actions throughout the day?
How do we measure daily activity patterns?
Attach a sensor to any pillbox to keep track of when medication is taken.
Attach a sensor to the refrigerator and other kitchen objects to infer
when food is prepared or consumed.
Attach a sensor to a movable object that is part of the daily routine
patterns of older adults to log more detail (e.g., bathroom door
or favorite chair) in order to log more detail.
To answer your question:
from the USA Today article:
It doesn't monitor sleep or measure heart rate or other vitals.
The step counter isn't the most accurate. What is being measured is
the movement of the watch, so my steps tally climbed even when I lay in bed.
Also, Googling for +"Lively Medical Alert Watch" +pulse returned zero hits.
When the company says
infer when food is prepared or consumed
it doesn't fill me with confidence.
I also quibble with "keep track of when medication is taken", and say that they can infer that pills have been taken form a pill box, but not that they have been ingested.
Does this answer your question? It took me 5 minutes Googling, although, in your place, I would have emailed the manufacturer directly.
