G'day Cberrien. Welcome to Apnea Board.
As you can see from your own charts, you have a fairly high (and increasing) proportion of central apnea. This can be pre-existing or treatment-emergent. It's important to know which it is, as that can guide the therapy decisions. Are you able to post a copy of your sleep report? We need to see the charts & tables, not just the summary. Make sure you blank out any personal data (address, phone number etc) before posting.
Just by way of explanation, many new users get some central apneas as the body adjusts to the new way of breathing. You're breathing more efficiently, which depletes the level of CO2 in the blood. This is a good thing but if the CO2 goes below a certain threshold the brain says "everything's OK, there's no need to breathe just yet". And you get a central apnea. Often these go away after a few months but sometimes they can be persistent.
The machine you're currently on will not treat central apnea, and it sounds like your doc is on the right track in suggesting an ASV. You mentioned a heart condition - the current guidelines (which may change) contraindicate ASV for people with congestive heart failure and a low left ventricle ejection fraction. So you'll probably need an echocardiogram or similar to confirm you don't fall into this category. As an aside, the study which turned up this contraindication is not universally accepted and a new study is under way which seems to overturn the earlier results.
If you do get an ASV machine, try to ensure you get the Resmed Aircurve 10 ASV. There is an equivalent Dreamstation model but experience among members here indicates that the Resmed is more comfortable and generally more efficacious.
One final thing - could you have a look at the instructions for organising your Oscar daily screenshots please? Te default setup with calendar and pie chart obscures some important information. The instructions are here:
