"This guy can not breathe, and he's got this robot trying to talk to him", she said.
"You might not make it home", the doctor said on the screen.
A family friend wrote in a Facebook post: "That Robot Dr may be OK for some situations but not to tell a man he is going to die". "I think the technological advances in medicine have been wonderful, but the line of "where" and "when" need to be black and white", she added.
While they awaited the results of a CT scan, Quintana, 54, and her mother decided they would quickly go home to shower.
"If you're coming to tell us normal news, that's fine, but if you're coming to tell us there's no lung left and we want to put you on a morphine drip until you die, it should be done by a human being and not a machine", his daughter Catherine Quintana said.
"I was so scared for him and disappointed with the delivery", Wilharm said, choking up.
Ernest Quintana passed away on Tuesday. But they're angered by the way the situation was handled and how the news was delivered. "When I took the video, I didn't realize all of this was going to unfold", she told KTVU.
Because the robot couldn't get to the left side of the bed, Ms Wilharm said she had to repeat everything the doctor was saying as her grandfather was hard of hearing in his right ear.
Michelle Gaskill-Hames, senior vice-president of Kaiser Permanente Greater Southern Alameda County, said in a statement that its policy was to have a nurse or doctor in the room when remote consultations took place.
"The evening video tele-visit was a follow-up to earlier physician visits", Gaskill-Hames said in a written response.
She said after the visit, he gave her instructions on who should get what and made her promise to look after her grandmother. "This secure video technology is a live conversation with a physician using tele-video technology, and always with a nurse or other physician in the room", Kaiser Permanente said. "We use video technology as an appropriate enhancement to the care team and a way to bring additional consultative expertise to the bedside".
Wilharm said the in-person doctor was "very sweet" and held her grandfather's hand as she spoke with him about hospice care and his options.
Hospital administration officials claimed that video conferencing has "worked wonders" for their patients and the patient's families because they're warm and intimate.
