Question
Indicate whether each statement is correct or incorrect for this 160 pound person with the following values VE = 16 L/minute I = 12/min PaCO_2 = 30 mm Hg PECO_2 = 20 mm Hg The subject is hyperventilating VT = 0.75 L VD/VT = 0.33 VD = 0.2 L/breath correct incorrect You have a subject with the following measurements Highest pressure at the mouth during inspiration = 40 cm H_2O, highest pressure in the alveoli during inspiration = 30 cm H_2O, end-expiratory pressure = 0 cm H_2O, inspiratory flow rate a 50 L/minute, VT = 350 mL Select correct or incorrect for each the following statements Cs = 117 ml/cm H_2O Raw = 0.2 cm H_2OL/sec The value of one time constant = 0.14 sec The compliance is within normal limits correct incorrect Select all of the following that are accessory muscles of expiration stemomastoid diaphragm correct incorrectExplanation / Answer
1)given VE = 16L/min
f=12/min
PaCO2 = 30mmHg
PECO2 = 20mmHg
VD/VT = (PaCO2 - PeCO2) / PaCO2
= (30-20)/30
=10/30
=0.33
VT/VD = 0.75/0.25
=0.33
Hence it is correct
3) It is incorrect as diaphragm is a primary muscle which help for breathing it is not accessory muscle.
