[Noah930]

Mrs. Noah is/was a nurse practitioner for MM patients in a previous lifetime. But that was pre-Covid and as an outpatient basis, so not necessarily directly applicable to your family member in the ICU.

Is your FIL getting daily lovenox (injections)? He was receiving subQ heparin injections in the past? Or an IV heparin drip?

There are 2 slightly different issues with anticoagulant treatment FWIW. Lovenox and heparin don't dissolve clots. They just prevent clots from forming/propagating. It's a thrombolytic drip that will dissolve a blood clot.

The PE is already there. Your family member hasn't passed, yet. The body can/will dissolve it itself with time, even without anti-coagulant agents.

Best wishes for your family member in this challenging time.
