We've learned that we can no longer depend on the presence of a priest for Extreme Unction.  We now see how quickly the government or self imposed powers that be (health department) can deprive us of our end of life sacraments.
It is our responsibility to be prepared while we are still in good health and still have our faculties about us.  Holy Mother Church has given us the remedy should such misfortune befall us.
 
In most old prayer books and the Raccolta, you will find in the prayers after Communion the "Plenary indulgence in Articulo Mortis".   This indulgence will take affect only at the moment of death.   It reads:
 
" To all who, with sincere love towards God, after confession and communion made on any day they may choose, say the following prayer:
O Lord my God, I now at this moment, ceadlity and willingly accept at Thy hand whatever kind of death it may please Thee to send me, with al its pains, penalties, and sorrows.  Amen - Pius X March 9, 1904"
 
 
Offer that same communion as your Viaticuм should you be deprived of a priest
 



 
Then stay in a State of Grace so it will be effective should you need it.
