"Concerned about overworked staff"

I had to have a stay in Dr Grays Hospital after being admitted through the A&E department.  I have absolutely no complaints about my care, my concerns are about the overworked staff who are clearly totally exhausted and deflated.  I have previously worked at the decline in recent years.  Entry to the ward showed corridors full of equipment, laundry etc,  is there not a store room?  One nurse was on their knees exhausted after a 12 hour shift with no breaks, hardly any drinks with the thoughts of leaving the profession.   A shocking waste of nurses time was spent looking for the red folders and equipment.  Can the stats machine not be made computerised to avoid this?  I had to be on oxygen for a while but there was only one portable cylinder for the whole of the ward which would have to go to other patients needing to go for tests or even the toilet! More often than not it was taken off my bed.  At one point I was given the emergency oxygen cylinder because there was really nothing else.  The nebuliser was also taken from me as there was not enough.  There wasn’t enough water jugs to go round,  most of the time it was a disposable plastic cup on our tables with water in it,  easily knocked over and not environmentally friendly.  Can the volunteers not come back?  This would relieve a little pressure on the staff with regards to the tea rounds. The pharmacy I was told,  is not open at the weekend,  this could mean that,  yet again, the nurses suffer by having to get together medication sometimes having to go to other wards to get this.  Surely Dr Grays is big enough to have the pharmacy open 7 days?   I feel so sorry for the loyal hard working, underpaid staff who are trying to keep it together but unless the management get an urgent plan of action with immediate affect I fear we will lose more of these fantastic workers.
