Elastic WOB
Compute elastic work of breathing per breath as one half times elastance times tidal volume squared, converted to joules with 0.0981 J per cmH2O-L.
Description
Compute elastic work of breathing per breath as one half times elastance times tidal volume squared, converted to joules with 0.0981 J per cmH2O-L.
Elastic WOB is a focused biology tool that compute elastic work of breathing per breath as one half times elastance times tidal volume squared, converted to joules with 0.0981 J per cmH2O-L. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use Elastic WOB
Use Elastic WOB when you need to compute elastic work of breathing per breath as one half times elastance times tidal volume squared, converted to joules with 0.0981 J per cmH2O-L. Enter Elastance and Tidal volume using the definitions and units below so the result can be reproduced.
- Elastance
- A finite measured or assumed value, expressed in cmH2O/L.
- Tidal volume
- A finite measured or assumed value, expressed in L.
How Elastic WOB calculates the result
The published tool contract uses this rule: Compute elastic work of breathing per breath as one half times elastance times tidal volume squared, converted to joules with 0.0981 J per cmH2O-L.
- Elastic work per breath
- The calculated elastic work per breath in J/breath.
Limitations of Elastic WOB
The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.
Alternative or Complementary measurements
Retain the original Elastance and Tidal volume values and their units alongside the result. Resistive WOB is useful when you instead need to compute resistive work of breathing per breath as resistance times inspiratory flow times tidal volume, converted to joules with 0.0981 J per cmH2O-L. Work Of Breathing provides another view by helping you convert a ventilatory pressure into mechanical work per liter of ventilation using the 0.0981 J/L per cmH2O factor.
