"Lack of nursing staff"

My child is a special needs kid that was first admitted to PCH when they had a chest infection. My child stayed in ICU for about 4 days before they were transferred down to the wards and a day later they deteriorated and went back to the ICU which few days they were diagnosed with pancreatitis, and spent three weeks in the ICU. 

After slightly recovering and being able to breath without ventilation, my child was transferred back to the wards where the nursing support being 1 nurse to 4 patients. My child was and is (at the time of writing this story) still going through rough withdrawals from the opioids. They were shaking and crying and we raised our concern that we needed to at least have a 2 to 1 ratio of patients to nurses.

Last week we stepped out of our child’s room and came back shortly after to find them blue in the face, oxygen saturation levels at 23%, monitors blaring and no one was the wiser. I started screaming for help and that's when they all rushed in. As I understand it, the nurse looking after my child was on break and the one taking over was busy and no one was on the central monitor. They took our concern and made the care 3:1. 

This happened again when my parent was with my child and they had a major seizure that lasted 1.5 minutes and their oxygen levels went down to 30%. Same scenario, nurse was busy and no one at central monitor. 

We raised the concern with the doctor on shift that day and they promised they will make it to 2:1 ratio but the nurse told us that sorry we don't have enough people to cover shifts. 

We cannot guarantee as parents and carers being in our child's room 24/7 and the medical team should not rely on us to be in the room to cover their apparent shortage in staff and lack of monitoring. 

We are fearful to leave our child alone in case they are not monitored properly, and ends up suffocating as a result and dies from absence of monitoring caused by lack of nurses.
