However, experts say she may not have displayed any outward signs of pregnancy and it could have been missed, especially by staffers who don't work with pregnant patients.
A few minutes later, the nurse expressed relief, saying "thank God" the baby was now breathing and crying.
That was the desperate cry of a nurse at Hacienda Health in Phoenix, Arizona, after staff discovered a patient in a vegetative state was giving birth.
The paramedic asked if anyone was doing CPR and described how to do proper compressions with two fingers in the centre of the baby's chest.
Court documents revealed that the woman received a medical exam almost nine months before giving birth, during which the doctor who examined her found "no change" in her health, according to the form, noting the exam was external only.
Their conditions have not been released.
The revelation that an incapacitated woman was raped inside a care facility has horrified advocates for people with disabilities and the community at large. They are gathering DNA samples from the facility's male staffers and have appealed to the public for any information. It has multiple complaints dating back to 2013, most for emergency preparation or Medicaid eligibility, according to the state's online complaint database for care facilities.
The CEO of Hacienda HealthCare resigned this week as the provider announced new safety measures, including more than one staff member being present during patient interactions and more scrutiny of visitors.
Hacienda HealthCare serves infants, children and young adults who are "medically fragile" or have developmental disabilities.
The notion that none of the woman's caregivers knew she was pregnant has drawn scepticism. But the 29-year-old woman, who is described in a medical report as having tubes to feed her and help her breathe, may not have had a swollen belly, according to a doctor of fetal medicine.
The mother could actually lose weight in other places like her face or arms if a fetus is consuming nutrients, Huls added. "So, her weight may not change because she's not taking additional calories".
It remains unclear to investigators if the woman was raped a couple of times.
The woman's mother, who is now her legal guardian, submitted an annual report as required by state law that included the results of a physical that was conducted on April 16 at the facility.
The family's attorney has said they are 'outraged, traumatized and in shock by the abuse and neglect of their daughter at Hacienda HealthCare.' The family will care for the baby, the attorney said.
