Air consumption, oxygen uptake (VO(2)), carbon dioxide output (VCO(2)) and respiratory exchange ratio (RER=VCO(2)/VO(2)) were measured directly from the self-contained breathing apparatus (SCBA) as 36 professional firefighters (three women) completed scenarios of high-rise stair climbing and fifth floor search and rescue. During stair climbing VO(2) was 75+/-8% VO(2max) (mean+/-SD), RER=1.10+/-0.10, and heart rate=91+/-3% maximum (based on maximum treadmill data). Firefighters stopped climbing… CONTINUE READING
