Hi There,
I think this is true for all hospitals. Chest compressions are classed as an aerosoled treatment, so poses a high risk of transmission to the attender. Please see the updated guidance by the resuscitation council UK .
It is not that doctors are being told not to perform CPR, they are being told to wear the correct PPE before they commence CPR. This may cause a delay in CPR, this also highlights the importance of discussing treatment escalation plans with patients and their families.
