Chris Cuomo is stating he has had hallucinations with COVID-19. That fits with blood shot eyes. It is irritating the nerves in the head. Inflammation. That’s my take on it.
He needs to be checking his blood pressure and temperature regularly and reporting it to his doctor if they are abnormal and not resolving with acetaminophen.
If he were in the hospital on a general medicine floor vital signs are every 4 hours along with a measurement of oxygen levels with a pulse oximeter that is placed on a finger.
