Thinking about problem of treating patient without adequate PPE. Imagine this: a 50-yr-old, suspected COVID patient (with no co-morbidities) chokes on food. HCW (a healthy, 35-year-old) has no adequate PPE. Patient loses consciousness. No breathing. Should HCW start CPR?

One of my US colleagues recently sent me their hospital's CPR guidelines, which state: "Clinicians are not obligated to perform resuscitation without appropriate personal protective equipment." I haven't seen CPR guidelines from NHS Trusts so can't comment on their position.

Let’s try to solve this. Assume no PPE-equipped HCW nearby. Some key questions: how likely is patient to benefit from CPR? What is approx. risk to HCW of 1. contracting COVID; 2. if gets it, suffering signif. harm from it? If HCW off sick, likely impact on care of other patients?

Any other considerations in determining whether HCW should attempt CPR? Or, in @mancunianmedic's formulation, should be morally blameworthy for NOT attempting CPR? (Please, no silly suggestions such as "what if patient is notorious gang leader/about to find cure for cancer,etc.")
