From this it gives (in December 2019) 4048 Adult critical care beds - 75.3% occupancy
and
309 paediatric critical care beds (in December 2019) 79.6% occupancy (neonatal beds not included in this)
East of England has 337 adult beds open; 13 paediatric beds open
London has 1027 adult beds open; 127 paediatric beds open
Midlands 680 adult beds open; 51 paediatric open
NE and Yorskshire 643 adult beds open, 54 paediatric open
NW has 543 adult beds and 38 paediatric beds open
SE has 523 adult beds and 31 paediatric beds open
SW has 303 adult beds and 18 paediatric beds open
Given that it has been a severe flu season it should be a reasonable guess that these were the maximum available beds, due to constraints of any one or combination of the following - Money, equipment, beds, specialist staff. It would also be reasonable to assume that only critical care / ICU beds have ventilators as I dont have specific figures for these.
If we assume EVERY bed was available for COVID 19 then we are still looking at a tiny number of severe patients being able to be treated; for reference, the severe patients needed ventilators and oxygen, the critical ones needed full ICU (please do correct me if I am wrong on this). Lets just say for sake of argument that all beds (paediatric and adult) were occupied for COVID 19, then all the beds would be filled after 21,785 became infected, assuming the 20% severe or critical rate holds. Alternatively if there is a 70% baseline occupancy from other health issues, and only 30% of these beds are available we are looking at a total of 6,500 cases being generated anywhere in England (roughly) generating 1300 critical or severe cases i.e this is the number of cases that would take all the available ventilator beds by severe or critical COVID cases. This will be further complicated though as you cannot mix COVid patients with non-COVID patients. If case numbers here enter an exponential phase, it is entirely feasible that we could reach these sort of numbers in 2-3 weeks. If every case needs one of these beds for up to 3 weeks, then we will be looking at a tiny handful of cases that can be treated per week thereafter. Lets assume homogeneity in new case numbers, and we are looking at needing to constrain new cases to a maximum of 1600 new case per week, of which 320 will be severe or need ICU; Severe (240) or full ICU (80). I hope this makes sense.
Then what? If there are extra ventilators, how many are there, and who is going to run them? Are they going to start training other nurses in critical care, at least as far as ventilation goes? If not that, then what? Retired medics willing to come back would probably be best used in 'normal' patients?
In conclusion, I think we cannot afford to be as reactive as current plans seem to suggest. We will need to be proactive to keep numbers manageable, and even then...
