You do go also for concerns. If they wanted to move him into an area he can be monitored in, have the heart rate and oxygen saturations monitored with the possibility if later things get worse more invasive ventilation they would have done so, especially for such a VIP. ICU has a nurse per bed with a nursing station nearby and telemetry. A private room in a ward would not have that.
So basically he needs intensive care then. (they were happy when he sat up by himself, so yeah, it's bad)
