NoBlood

my sister was diagnosed with acute leukemia aml 2 weeks ago, she is an inactive jehovahs witness but has pure love & loyalty to Jehovah and wants no blood, she is currently hospitalized at Cedar Senai Hospital in Los Angeles, her hemoglobin is at 6, & her platlettes are very low, she needs 2 more weeks for her bone marrow to start producing healthy blood cells, is there any alternatives that will keep her cells stable? Please help, she is in good hands but she seems to get weaker every passing day, we are desperate and just want to make sure everything is being done to conserve her life now.
Any advise is completely appreciated!
