A couple of points.
1. In the Whitehouse briefing by Alex Azar (Secretary of Health and Human Services, Chairman of the President’s Task Force), they outlined why the travel ban was brought into place and specifically compared the current Influenza season.
Dr. Anthony Fauci (Director of the National Institute of Allergy and Infectious Disease) stated :
"Well, the reason is, despite the morbidity and mortality with influenza, there’s a certainty, for example, of seasonal flu. I can tell you all, guaranteed, that as we get into March and April, the flu cases are going to go down. You could predict pretty accurately what the range of the mortality is and the hospitalizations, as we’ve done over the years."

2. Mortality rates will be lower until resource limitations hit. That has already happen in China. This is inevitable that it will go up if we get run away here. (if recorded - because they die and you they arent investigated because it serves no therapeutic purpose)
3. Regarding the question of ICU resourcing :
The basic principles are:
a. will the therapy benefit the patient
b. can the therapy be given in an effective way (ie to completion)
c. can that resource be better utilised
d. how long will that resouce be "taken"
You can't give what you don't have - you cant ventilate someone if there is no ventilator or more importantly no one to look after them. Eventually what happens is resources are invested into "easy wins" so they can move onto the next - Negative triage (as is done in mass casualty). Essentially the greatest good for the greatest number.
So old and sick, dont get a look in, dont get investigated and are palliated early.
I think the numbers are going to get more and more rubbery as time goes on. With home lockdown, the old will die at home, and not be an official statistic (as they were never tested).
As an example, H1N1 stretched the whole first world critical care services. The sheer numbers of 2019-nCoV and rate of rise is staggering.
Put quite simply - If China can't cope - we will find it hard to cope.
