Purpose:
To make the capacity model of SMART new-type multi-functional ventilator achieve the capability that the flow can be stable and adjusted accurately.
Methods:
To analysis the problems in the course of development with fluid mechanics principle, find the deficiencies of original design and improve it.
Results:
The inspiratory phase waveform of IPPV. SIMV,etc, breathing pattern presented square wave, achieved the goal of adjustable flow.
Conclusions:
Using the fluid mechanics principle guiding the design of ventilator gas circuit can get twice the result with half the effort.

Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...
