how can a patient with pul fibrosis minimize his work of breathing in terms of resp freq and tidal volume?

  #2

pulm fibrosis = restrictive disease - he has problem with inspirium, so he must increase frequency becuse tidal volume is decreased due to restriction of pulmonary inflating
obstructive diseases - he has problem with expirium, so he must decrease frequency with increased tidal volume

in pulmonary fibrosis, there is a problem with inspiration,and yet the pts already remain tachypneic,while most of tidal volume is utilized to ventilate dead space! [unnecassary work]
so the best option is to take slower but deep breaths....thts wht respiratory rehabilitation and physiotherapy is all about!

excuse me
i think that for minimize the work , the restrictive patient should respirate at lower tidal volume ( superficial breathing ) because he spend more energy for expanding the stiff lung
and you know that increase in volume ( tidal ) equale to increase in recoil thus the restrictive patient should breath with low volume and for adequate ventilation he should increase the respiratory rate

RAPID SUPERFICIAL BREATHING

mamc whats the right answer? is increased frecquency ?
