The NHS is so understaffed it feels "more like a conveyor belt" a frustrated nurse has told Good Morning Britain.
The nurse said she had put a patient's life at risk "on many occasions" because she does not have time to monitor their vital signs.
She added: "I have been on duty where there has been one nurse to 14 patients. Elderly patients, who are totally dependent on you for their care needs."
It is "no surprise" that 82% of nurses who said they did not have enough time to provide adequate patient care, according to a health chief.
Chief executive of the Royal College of Nursing, Dr Peter Carter said:

This survey will sadly come as no surprise to nurses. Our members tell us that they are working extra hours just to get the essentials done but the NHS can't function on goodwill and commitment alone.
Nurses want to come to work and make a difference. It is hugely demoralising, not to mention potentially unsafe, if staff can't deliver for all their patients.
There is evidence of hospitals heeding the warnings of the Francis report and taking on more staff, but this is from a very low base at a time when demands are rising fast.
Four out of five nurses are so busy they do not have enough time to properly look after their patients, an exclusive poll has revealed.
The survey, conducted by ITV's Good Morning Britain and the Nursing Times, found 82% of nurses are so overworked they are unable to care for those who need them the most.
Some quarter of the 1,800 nurses quizzed expressed concern over low staff numbers and the amount of paperwork required of them.
Meanwhile two thirds said they were worried about the level of care that their place of work gives to patients outside of normal office hours.
And 88% said that the Government should introduce a mandatory minimum nurse to patient ratio.
