PFD Monitor interpretation
Remind nursing staff of expectations for safely caring for patients receiving oxygen therapy.

Verbatim wording from the response
“The expectation is that if a nurse leaves the patient, they will notify the patient/relative/visitor of where they are going, how long they will be and to call, if assistance is required. Nursing staff will be reminded of the expectations involved in nursing patients receiving oxygen therapy.”

PFD Monitor interpretation
In acute deterioration, it may not be possible to provide additional staff to supervise a patient removing oxygen therapy.

Verbatim wording from the response
“care to assist with giving oxygen therapy safely. However, in an acute situation, such as EM’s situation, where the patient deteriorates quickly, it may not be possible to facilitate extra staff and the focus would be on providing immediate treatment. It is expected that nursing staff would escalate the fact that a patient is agitated and removing their oxygen mask to the doctor/nurse in charge. It would be reasonable for a nurse to leave the patient for a short period in order to communicate with colleagues/escalate any concerns, if the patient was settled. Patients’ relatives can be very helpful in reassuring and calming patients to assist with giving therapies such as oxygen but there would not be an assumption that they would deal with administering the therapy.”

Failure to prevent unsafe disconnection of oxygen supply and departure from the ward
Wider context from the report
“2. The Alexandra Hospital Staff Nurse conceded that Mrs Ellams was discharged from hospital even though it is now clear that her oxygen saturations were still too low for such discharge to take place. There was what appeared to be a very lax attitude to recording and monitoring the Blood/Oxygen levels and the patient was allowed to disconnect her oxygen supply and walk out of the ward to go for a cigarette.

PFD Monitor interpretation
Failure to supervise patients requiring oxygen while they are in ward facilities
Wider context from the report
“iii. There was no handover in relation to Mr Gillard’s transfer from the Emergency Department at the Hospital to D1 Ward at the Hospital, particularly in relation to his need for Ambulatory Oxygen and subsequently he was taken to the toilet without the use of Oxygen. He was left in the toilet on his own, and without supervision by a Nurse outside the door, for approximately four minutes during which he suffered a cardiac arrest believed to be secondary to Hypoxia. iv. It was accepted that there was a facility to use a portable Oxygen supply for use between his bed and the toilet but the portable supply was not used because Mr Gillard was happy to go to the toilet without Oxygen and his need for Ambulatory Oxygen was not known to the Ward Staff on D1 Ward. ”
