The first tests of the portable mechanical ventilator built by a team of specialists from the University of Costa Rica (UCR) are ongoing to meet all the requirements for their eventual use in the hospital centers of the Costa Rican Social Security Fund (CCSS).

This was indicated by Dr. Ralph García Vindas, director of the School of Physics and one of the promoters of this initiative, called “Respira UCR”, with which it aims to contribute to the country in the face of the health emergency of COVID-19.

On April 30, the first test was performed on the operation of the device in pigs, at the Intensivet veterinary clinic, where there is a surgery room for large species.

The Costa Rican Chamber of Pig Farmers collaborated with the donation of two pigs, weighing approximately 80 kilos, who were brought to the capital from the canton of Upala, on the country’s northern border.

On this occasion, a great advance was made, according to García, since it was verified that the volume of air supplied by the fan was correct and that this device did not fail during the procedure.

This preclinical trial will be completed this week, due to the fact that the programming of the equipment regarding the breathing cycle is not adequate.

“This means that if we program the team to deliver a breathing cycle, for example, of 20 breaths per minute, the animal actually receives that number of breaths per minute,” explained the physicist.
