dwd here is a simple rule of thumb, if you know you double lunged the deer, unless it goes down in plain view always give them half an hour before you even leave the stand, even if they go down in plain sight and you are sure it is dead wait at least 15 minutes. If you have hit high or did not get a passthrough wait at least an hour, if you hit to far back, just behind the ribs and get a pass through, wait about 15-20 minutes and slowly get out of your stand and check the arrow, if it is dark dark blood and no green/guts on the arrow you probably hit the liver, wait at least 2 hours or if it is starting to get dark and it will be cool over night come back first thing in the morning.
The worst thing you can do in any situation is to push the deer, most deer if hit hard will not go real far and they will lay down and unless pushed will stay there until they bleed out. If you push one, you will find out how far adreniline can take a deer with both lungs blown.
