She did not however advise the woman to consult a specialist and did not take additional steps to improve the woman's condition.
The following morning, the woman advised the midwife that she had experienced headaches and further visual disturbances.
The midwife asked the woman to report any further disturbances but did not arrange to assess the woman urgently in response to the symptoms reported, the Commissioner found.
That evening the woman began to experience contractions and was admitted to hospital where she met with the midwife.
Again the midwife noted the woman had high blood pressure but did not carry out any further assessments. She then left the room.
When she returned, the woman was feeling faint and her blood pressure was very high.
The on-call registrar was called, who then took over the woman's care.
In the report, released today, Mr Hill referred the midwife to the Director of Proceedings where it will be decided whether any proceedings will be taken.
