No pulmonary care: yes, it's possible. Glen had a bipap here but would rarely use it. How the illness played out would depend on his particular symptoms but most likely scenario is that as his breathing ability decrease, his CO2 levels would increase and he woud basically fade away. Palliative care involves keeping a patient comfortable .. pain meds, anti depressive meds, anti anxiety meds.. rather than doing anything "curative." What that involves depends on the hospice and doctors involved.
