The frightening reality, says Gardiner, is the current trajectory does not bode well.
"When I have to make a really difficult decision - if we get to the point if resources won't go far enough - I hear no voice that says, 'we support you in whatever decision you have to make, ethically or socially'. How do we decide which people get a longer time in critical care or who gets it in the first place?"
He admits that conundrum keeps him up at night and is "not a medical decision" but a "social, political and economic decision".
Inside this hospital, there's the constant ringing of alarms, the noise of the ventilators that are keeping patients alive and the arrival of more very sick people.
