That is per shift.
We have about 100 nurses on staff including part-timers and PRNS.
Ratios depend on acuity and staffing. We can have 4 kids...mostly they are feeders, sometimes there is a CPAP or NIMV thrown in there. Our vents are usually paired together, or with one or two feeders, never more than 2 vents. Trachs, since they are usually really bad kids, usually only with one other kid. Our bigger chronic kids we try to only give one other with too. But this all depends on staffing and acuity. We do have the occasional one-on-one, usually a kid that is on HFOV or really unstable.
I have to say, I work with a good group...we will do what needs to be done and if someone has an admit we all pitch in to help..that may mean taking 5 kids, but if it is doable, we do it.
We try to keep the charge nurse without an assignment so that she can help out and pick up kids if there is an admit. Our transport nurse has to have an assignment that has kids that are easily absorbed into another assignment.
