Respiration Control
Applied Tension/Respiration Control
Volunteer blood donors complete assessment materials, including assessment of respiratory activity, but otherwise undergo the typical blood donation procedure.
Participants are taught a simple muscle tensing technique with a brief video presented on a notebook computer before giving blood. They are asked to engage in repeated gentle 5-sec on, 5-sec off cycles of whole body isometric muscle tension before and while giving blood.
Participants are taught a simple respiration control technique with a brief video presented on a notebook computer before giving blood. They are asked to breathe in a gentle shallow but regular fashion aimed at reducing risk for hyperventilation before and while giving blood.
Participants are asked to practice both Applied Tension and Respiration Control before and while giving blood.
