## Abstract

The invention relates to a modular ventilation system, apparatus, kit, and method of use. More specifically, the invention relates to a ventilation apparatus comprising modular components to provide time controlled adaptive ventilation to one or more individuals simultaneously using one gas source and multiple valves proximal to the patient such as to provide individualized ventilation. The modular components can be easily manufactured and assembled in flexible configurations in any number of ways.

## Claims

### Claim 1

b. A pressure-flow regulator to regulate a pressure in the gas flow,
c. At least one of a venturi or gas blender to introduce oxygen into the gas flow,
d. At least one system manifold to provide gas flow to the at least one patient or lung,
e. At least three pressure relief valves,
f. A time cycled pressure release valve, and
g. A time controller.
wherein the at least three pressure relief valves comprise an inspiratory pressure relief valve to regulate inspiratory patient pressure, an expiratory pressure relief valve to regulate expiratory patient pressure, and a manifold pressure regulator valve to regulate manifold pressure,
wherein the at least one system manifold comprises at least three connectors, comprising a source connector that connects a first manifold to the gas source, a patient connector that connects the at least one system manifold to a ventilator circuit that delivers the gas flow to the at least one patient or lung, and a manifold connector that connects the first manifold to the manifold pressure regulator valve or a second manifold, and
wherein the inspiratory pressure relief valve, the time cycled pressure release valve and the expiratory pressure relief valve are proximal to the patient or the lung, and individually adjustable for each patient or lung.

### Claim 2 (depends on 1)
