DNR without DNI?

Do you guys typically offer to make patients DNR without also making them DNI? I'm not talking about patients who have conditions that are likely reversible such as pneumonia. Mainly asking about patients with many comorbidities who would be unlikely to be extubated if they were ever intubated or have advanced dementia/COPD/CHF. I've always felt that CPR and intubation cross a certain line and if they are unlikely to bring the patient back to a reasonable baseline, they should not be offered... DNR without DNI?
