Amale patient presents with the following respiratory volumes and capacities: tv = 500 ml, erv-600 ml, irv 2,700 ml.
what is this patient's vc? are these values normal? if not, are they more consistent with an obstructive or restrictive disease pattern? explain.

The patient VC is 3800ml.

Explanation:

Vital capacity may be defined as the maximum amount of air that a person can expel after maximum inspiration. Tidal volume is the sum of  expiratory reserve volume, inspiratory reserve volume and tidal volume.

Vital capacity (VC) of a patient is 3800 (500+600+2700). The patients has restrictive disease pattern because its expiratory reserve volume has been decreased. The patients suffers from the lung restriction and respiratory failure.

Thus, the patient VC is 3800 ml and has restrictive disease pattern.

explanation:

for example, code 28039 - excision, tumor, soft tissue of foot or toe, subcutaneous, 1.5 cm or greater, appears before 28043 - excision, tumor, soft tissue of foot or toe, subcutaneous; less than 1.5 cm.
