Att the start of the pandemic Sweden had the next-lowest number of ICU places per capita in Europe (Portugal had the lowest). The capacity was doubled, field hospitals were built... and not used since the hospitals could handle the inflow. This was partly due to some very controversial and in my opinion unethical guidelines which mandated morphing instead of oxygen for certain groups of elderly (i.e. involuntary euthanasia) but it is unknown if those policies had much effect on the park ICU occupation.
Apart from some bad mistakes in the beginning where the infection was allowed to spread in care facilities Sweden has weathered the epidemic (as in the local version of the pandemic) no worse than surrounding countries and certainly no worse than e.g. New York.
