Question

1. During a test of maximal voluntary ventilation, the client/patient breathed at a rate of 65 breaths/min. As the test administrator, you should

a.) Repeat the test, breathing rate should be approximately 85-110 breaths/min

b.) Average this test result with at least one trial

c.) Repeat the test, breathing rate should be 40-50 breaths/min

d.) Use this test result as it falls within recommended standards

2. When performing pulmonary function testing in a clinical setting, obtaining adequate results typically requires

a.) A minimum of 3 acceptable FVC and FEV1 trials that differ by no more than 150 ml (0.150 L)

b.) A minimum of 8 acceptable FVC and FEV1 trials that differ by no more than 250 ml (0.250 L)

c.) A minimum of 4 acceptable FVC and FEV1 trials that differ by no more than 250 ml (0.250 L)

d.) A minimum of 3 acceptable FVC and FEV1 trials that differ by no more than 300 ml (0.300 L)

Answer 1

answer 1:-

(B) average this result.......

this can be measured using a spirometer,but the peeiod of maximal bearthingbis limited to 15 s because the individual cam become alkalotic and he can fatigue.

the maximum voluntary ventilation was 2.8 p and RR is 15 breaths im the 15 s period,giving 60 breathes min-1.

answer 2

(d) a minimum of 3 acceptable....

it depends on the FVC calculated for your age, height, weight,the ration of these two values is then evaluated.
