Question

Resplratory volumes and capacitios Respiratory Rate-12-18 breathes per minute adult at rest (1 per every 4 heart beats) 18-20 children Respiratory Minute Volume (RMV) volume of air moved each minute RMV rate (breaths/minute) X tidal volume (ml) Tidal Volume (TV) = 500 ml Inspiratory Reserve volume (IRV)-3,300 m Expiratory Reserve volume (ERV) = 1.000 ml Vital Capacity (VC) = 3.100 (w) , 4800 (m) Residual Volume (RV) = 1.200 ml Total Lung Capacity (TLC)-6,000 m VC TV +IRV+ERV TLC VC+ RV Calculate Respiratory Minute Volume (RMV) Breathing rate (breaths min Average volume TV Respiratory Movedpereycletmi Minute Volume (ml min AL 6000 550 Subject 1 Subject 2 Subject 3 15 (B) -- 700 8400 (D) 5000 1000 5000 500 400 (H) 12 (FI (G) 45003000 1100 O 3200 6000 20

Explanation / Answer

(A): 6050ml

RMV=Rate(Breaths/min)×Tidal volume(ml)

RMV=11×550

=6050ml

(B):400ml

As already known that RMV=Rate(breaths/min)×TV(ml)

TV=RMV÷Rate(breaths/min)

TV=6000÷15=400ml

(C):12breaths/min

RMV=Rate(Breaths/min)×TV. Rate=RMV÷TV

=8400÷700=12

(D):10breaths/min

Rate=RMV÷TV

=5000÷500 =10

(E):3500ml

VC=TV+IRV+ERV

5000=500+IRV+1000

5000=1500+IRV. IRV=5000-1500

=3500

(F):4800ml

RMV=Rate×TV. 400×12=4800

(G):1100ml

VC=TV+IRV+ERV

4500=400+3000+ERV. 4500=3400+ERV

ERV=4500-3400=1100

(H):300ml

RMV=Rate×TV. TV=RMV÷Rate

=6000÷20 =300

(I):4600ml

VC=TV+IRV+ERV

=300+1100+3200

=4600
