II. Interpretation: Inspiratory Volumes

  1. Inspiratory Reserve Volume (IRV)
    1. Maximal inspired volume from end-tidal inspiration
  2. Tidal Volume (Vt)
    1. Volume inspired and expired with each normal breath
    2. Minimum volume: 3 ml/kg
    3. Normal volume: 6-7 ml/kg
  3. Inspiratory Capacity (IC)
    1. Maximal volume inspired from resting expiratory level
    2. Calculation: IRV + Vt

III. Interpretation: Expiratory Volumes

  1. Expiratory Reserve Volume (ERV)
    1. Maximal expired volume from end-tidal inspiration
    2. Normal: 25% of Vital Capacity
  2. Residual Volume (RV)
    1. Volume remaining in lungs after maximal expiration
    2. Normal adult: 1.0 to 2.4 Liters
  3. Functional Residual Capacity (FRC)
    1. Volume remaining in lungs at resting expiratory level

IV. Interpretation: Overall Lung Volumes

  1. Vital Capacity (VC)
    1. Maximal volume expelled after maximal inspiration
  2. Total Lung Capacity (TLC)
    1. Volume in lungs at end of maximal inspiration
    2. Calculation: VC + RV
    3. Normal adult: 4-6 Liters

Ontology: Total Lung Capacity (C0040509)

Definition (MSH) The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.
