Plumbing and Gas Connections

The plumbing of VentCU is fully composed of common breathing connectors, many of which are interchangeable with other similar parts. This device is meant to run completely off of room air, meaning that no oxygen source is required to supply the patient. However, it is capable of using a gas source if such resources are available. The following diagram provides an overview of our recommended breathing circuit setup.

Basic Diagram of the Breathing Circuit

The first connection starts with a PEEP Valve and Pop-off Valve, which are typically included with a standard Ambu-bag.

CPAP extension tubing is then used to lengthen the distance between the device and the patient.

A suitable tee adapter is then used to connect the extension tubing and HEPA filter, as well as to provide an opening for testing connections. In our case, we connected a pressure sensor on the testing end of the tee adapter.

After the HEPA filter is connected to the end of the tee adapter, an endotracheal tube is directly attached from the filter to the patient. This is the general order in which VentCU’s breathing circuit is arranged.

Depending on the sizing of each individual connection, fittings may be required to couple each section together. This is especially relevant for the testing connection, which can vary based on the pressure/flow sensor used.
