rate, depth of breathing and sound quailities
normal rate of breathing in an adult
12-18
normal rate of breathing in a child
24
breathing rate of a bb
40-60
factors influencing breathing rate:
increasing
fever anxiety lack of oxygen exercise stimulant drugs
factors influencing breathing rate:
decreasing
sleep
relaxtion
hypothemia
depressant drugs
