Abstract
A spirometry-based device for continuous monitoring of work of breathing (WOB) includes a flow sensor and a respiratory mechanics module connected with the flow sensor. The flow sensor may sample an airway gas flow and an airway pressure when a patient is in a state of inspiration. The respiratory mechanics module may calculate an incremental amount of a gas volume that flows to the patient side in a sampling period, calculate a product of the airway pressure and the incremental amount of the gas volume in the sampling period, and accumulate the product into the WOB.
