Yes

No

Does not a commercial CO detector work adequately? Would not a pair of them be sufficiently safe if tested regularly. Remote locate a catalyst heater with one CO detector alongside, the 2nd CO detector goes at the head of the bed.
Crack the bedside window open for fresh air.
In my rented medical hideout, I am not going to donate 300 dollars for a heater plus the cost of flue and labor to install it.
If I read a compelling argument I will abandon plans for an LPG catalyst 3,000 BTU unvented heater.
