PFD Monitor interpretation Failure to recognise breathing difficulty and place an unresponsive person in the recovery position
Wider context from the report “When Ms Jaiyesimi was on the floor having suffered several fits, no person put her in the recovery position . They were apparently unaware that her present position could be causing an airway obstruction preventing her breathing.
Then when Ms Jaiyesimi stopped breathing, nobody recognised this, though they were looking at her and made one inadequate attempt to feel for breathing (by placing a single finger somewhere near her nose) .
No person ever attempted to check Ms Jaiyesimi’s pulse to see if her heart was still beating.
Even if they had identified her cardiac arrest, there was nobody present who would have started CPR. Nobody thought of fetching one of the store defibrillators. Lack of CPR notwithstanding, the failure to understand the situation properly meant that nobody relayed the crucial information of the arrest to the ambulance service.

PFD Monitor interpretation Failure to identify and deploy the available trained first aider
Wider context from the report “I heard that it was the duty manager’s choice not to be first aid trained. She said that she did not like blood and was afraid of the responsibility of a paramedic. However, on further exploration she said that she would like to be able to recognise a person not breathing and she would like to be able to administer basic first aid.
TSS
4. The TSS security officer was first aid trained, but did not tell anyone that he was first aid trained.
He told me repeatedly that his job was simply to do whatever the duty manager told him to do. Despite being the only first aider present, he took no responsibility at scene. He failed to offer Ms Jaiyesimi or the duty manager any meaningful support at all.

PFD Monitor interpretation Failure of first-aid training to produce basic first-aid competence
Wider context from the report “The SIA
The security officer had undergone SIA compliant first aid training in order to renew his licence. His first aid at work qualification was in date. He told me that his role as a security officer was to ensure the safety and security of people and merchandise in the store.
5. However, he did not display any understanding of basic first aid procedures . He told me that the first aid training he had received was simply a tick box exercise to enable him to renew his SIA licence.
• When the duty manager specifically asked him to check for breathing, his one attempt to do this was wholly ineffective.
• He never considered checking for a pulse. He told me that he had never been trained to check for a pulse.
• He said that he had not been trained in how to use a defibrillator and so he would not consider fetching one.
• When the staff member on the phone to the ambulance service relayed the instruction to place Ms Jaiyesimi in the recovery position, he did not. He told me that he did not remember being asked to do this. He also told me that he did not remember ever being taught the recovery position.
• Finally, the security officer said that if he did ever see anyone not breathing in the future, he would wait for the arrival of paramedics to attempt to do anything about that.
