As a volunteer (lay) assistant to the Chaplain in a large long-term & palliative care institution, my Sundays are normally hectic: Father celebrates 2 Masses - one in each pavilion. I set up the sound system and the altar in an auditorium, serve the Mass, do the readings (2) in French and (1) in English ; lead the prayer of the faithful ; distribute Holy Communion to half the auditorium -always vigilant of those who would present swallowing problems.
Any moments outside of that are usually spent bringing Holy Communion to patients who couldn’t leave their beds, or helping to bring patients to or from the Masses. When I mentioned to the first Chaplain whom I worked under at the beginning of this 20 years (and counting) apostolate , that I was discouraged because on Sunday , I didn’t have time to spend with the Lord personally upon the reception of Holy Communion, and that I was usually too exhausted by the time I got home to continue with the Rosary or the breviary , he told me:
“It can help to remember that serving a liturgical function (such as an EMHC) during Mass is itself both a prayer and a sacrifice. This prayer and sacrifice can be united to our Blessed Lord’s own Sacrifice during Mass - even if we only have a brief moment to concentrate on it ; any moment from the offertory all the way though to the per ipsum would seem suitable .”
Serving the liturgy actually helped me cherish those (weekday) Masses in my home parish where I was/am free to pray simply as one of the faithful without any liturgical duties apart from being there. On those occasions I do my best to try to be immersed in God during the entire Mass, but particularly at Holy Communion.
I believe Cor ad Cor’s points help to orient our thoughts properly.
I’m not trying to call the priest into question here, as I realize the biological reality of this statement, but from a spiritual and liturgical standpoint, this would render our sending forth at the end of Mass less efficacious, since the reason for nearly immediate dismissal after Communion is that we are to carry Christ into the world.
I’m simply trying to say that as Father pointed out above, your service is your thanksgiving, and you’re not working against the clock.
The Sacarament is called the Eucharist “because it is an action of thanksgiving to God.” CCC 1328 . So one’s service at a Mass (in this case, as an EMHC) is not only one’s thanksgiving, but equally part of what enables the entire congregation to participate in “the action of thanksgiving to God.”
Regarding how long our Blessed Lord “remains with us” in this Sacrament : One cannot receive Holy Communion and then, figuratively speaking, set the timer for 10 minutes - that’s quite outside the realm of what the Church contemplates for the faithful upon reception of Holy Communion.
I personally often ask Jesus at Holy Communion, as the disciples at Emmaus did, to “stay with me.” In this particular sense it would appear that St. Faustina might’ve come a little closer to perfecting the ideal in her daily life than many of us might have at the present moment:

She wrote, “Today, I have come to understand many of God’s mysteries. I have come to know that Holy Communion remains in me until the next Holy Communion. A vivid and clearly felt presence of God continues in my soul… My heart is a living tabernacle in which the living Host is reserved” (Diary, 1302).
