An emergency baptism means that the normal rites are not employed, but owing to necessity the minister (priest, deacon or even a lay person), baptizes someone desiring to be baptized, or a child before the age of reason who is dying, using only the necessary form (I baptize you in the name of the Father, and of the Son and of the Holy Spirit.) A priest having the holy oils with him would also confirm the person. Ordinary water may be used for emergency baptism, though holy water is prefered if available. If its called something else its not water (e.g. IV fluids). Even something so predominantly water as tea or coffee is doubtful matter. One could baptize conditionally with doubtful matter IF that was indeed all there was available and time was of the essence. For certain validity the water should be poured sufficiently so as to run, three times, over the forehead (if accessible), the head, other than on the hair, if not. If the head is not accessible, baptism may be performed on the breast neck or shoulders, though this is only probably valid. The arms, legs and elsewhere are considered probably invalid. The words should be spoken, even if inaudible to others, and not just said mentally. The Church has not ruled on such details, but the common teaching of theologians over the centuries should be followed. It would be presumptuous and dangerous to souls not to do so.


While children may not be baptized contrary to the will of the parents, except in danger of death (it's God's will expressed through the Church), an adult may never be baptized without an indication that this is his or her will. It would be in vain to do so, and an abuse of the sacrament. This would be objectively sinful, though you obviously are unaware of that fact and so are excused. The adult person to be baptized must have expressed their will in some way, and if opportunity affords given the minimum catechesis - God, Christ, Heaven (reward), Hell (punishment).
