VENTILATOR SHORTAGE? VENTILATOR SPLITTING!
The rapid spread of SARS-CoV2 throughout the world has put an unimaginable strain on the healthcare system. Patients are at risk of facing the consequences of not enough ventilators, which in dealing with respiratory failure is fatal. This is a last resort, emergency-only device for use if ever faced with a critical shortage of ventilators.
The concept of ventilator sharing to our knowledge was first written by Dr. Neyman and Dr. Irvin in 2006 (Ac Emergency Medicine 2006). They demonstrated that by using T-tubes and adapters, a ventilator circuit could be divided such that four simulated patients could share a single ventilator in emergency circumstances. Although only simulated in the original article, this technique was successfully used by Dr. Menes in the 2017 Las Vegas shooting mass casualty incident. This technique saved the lives of patients, buying time until more ventilators could arrive.
Some hospitals do not have the T-tubes or other parts readily available to setup a ventilator for multiple patients. This free 3D printed part can be used in such situations.
Our goal is to have an easily printed 3D part so that anyone in the world, who may need it in dire circumstances, can use it to save live.
RESPIRATORY FAILURE
2-4% of all COVID-19 patients will require mechanical ventilation.
VENTILATORS
The USA has approximately 160,000+ ventilators. Some projections suggest we will need 600,000+ at the peak of the COVID-19 outbreak.
The Need
A ventilator splitter is a device that allows a single ventilator to support two or more patients during this crisis. Approximately 2.4% of all COVID-19 patients in this pandemic will require mechanical ventilation.
The Solution
The ventilator sharing concept was first written by Dr. Neyman and Dr. Irvin in 2006 (Ac Emergency Medicine 2006). By using T-tubes and adapters, a circuit could be divided so four patients can share a single ventilator in an emergency. One group, Ventsplitter.org has released an open-source file for emergency POC uses along with flow limiters when pairing different patients (body weight, lung compliance, etc).
The Outcome
Additive manufacturing presents the opportunity to rapidly produce splitters for hospitals. We have several sterilizable and biocompatible materials available on all of our systems that can be used to print these parts along with several ISO 13485 certified facilities that can produce medical parts.
