ACPRC = Association of Chartered Physiotherapists in Respiratory Care
CABG = coronary artery bypass graft.
FRC = functional residual capacity, i.e. resting lung volume
IPPB = intermittent positive pressure breathing, e.g. the Bird
PLB = pursed lips breathing
QoL = quality of life
SOB = shortness of breath
SOBOE = shortness of breath on exertion
