These are the types of ventilators with which Mexico will attend to patients with coronavirus

Dr. María Elena Álvarez-Buylla presented four types of venitladores for patients serious of COVID-19 during the afternoon conference this Thursday to combat the pandemic in the country. He stated that in Mexico “there are many scientific and technological capabilities

Clarifying that he was going to focus on national medical devices because the President of Mexico, Andrés Manuel López Obrador, commissioned the National Council of Science and Technology (Conacyt) to coordinate the strategy for manage to build Mexican fans “in time” to face the pandemic.

He reported that the “goal” is reach technological sovereignty to face the pandemic, where they have at least 700 national mechanical fans by May 15. They will be invasive, with 100% Mexican technology, inexpensive, and with high quality and biomedical safety.

The four types of fans in Mexico are:

1. Ambu: it consists of arms that close synchronized to compress the bag, combined with a closed-loop control system.

2. Piston: it has a rigid chamber whose volume is mechanically manipulated to generate inspiration flow. “Much better volume control” and increased gas economy and quieter operation.

3. Valve: gas pressure regulation by means of valves that regulate the flow from an external tank. Flow rates of up to 200 liters per minute can be generated. This design uses “the least energy”, and depends on a stable supply of gas under pressure, with a minimum flow rate of 120 to 150 liters per minute and a minimum pressure of around 200 kilopascals (kPa).

4. Turbine: a compressor is used to produce pressurized gas flow. Potentially higher flow rates can be generated: up to 240 liters per minute. Can compensate for huge amounts of leakage. Requires a supply of compressed oxygen (capable of 120 liters per minute flow).

The Conacyt took care of coordinating the technical process and review engineering, quality, safety and training of various teams in conjunction with different public research centers and companies in the national industry for the construction of the fan models.

The doctor also critical to the Neoliberal Science of past administrations, describing it as a “dependence technological ”, with“limited articulation capabilities“,”low efficiency in innovation ”,“ millionaire transfers to the private sector ”,“ abandonment of basic science ”, and a private sector with“ minimal contribution to the national STI ”.

Furthermore, according to Álvarez-Buylla, they will be non profit, cheaper than imported ones, and with a accelerated production for the emergency.

“I think this crisis is inviting us, and this has been stated by many scientists in the world, to rethink the world organization in general, the neoliberal system. This that we are living, I am convinced like many and many, it is a symptom of the failure of a civilizing mode of a neoliberal system“, he claimed.

Too compared the Expenditure on Scientific Research and Experimental Development (GIDE) as a percentage of the Gross Domestic Product (GDP) between the United States, Italy, Germany, China, and South Korea. In Mexico, around 18% is the contribution of the private sector to technological development. “Scientific development and sovereign technological development capacity are essential for a country, “said the doctor.

In Mexico, the number of cases of people infected by COVID-19 increased to 11,633 confirmed patients, reported the Ministry of Health (SSa) this Thursday. The figure of fatalities grew to 1,069.

José Luis Alomía, General Director of Epidemiology, reported that there are 7,588 accumulated suspected cases and 39,664 accumulated negative cases. There are 4,127 active confirmed cases in the country and a total of 58,885 people studied.

The confirmed cases accumulated by state entity as of April 23 are: 3,157 in Mexico City, 1,734 in the State of Mexico, and 1,085 in Baja California. Durango, with 38, and Colima, with 16, are the states with the lowest numbers.

The undersecretary of Prevention and Health Promotion, Hugo López Gatell, announced this Wednesday that it is estimated that 8 out of 10 critically ill Mexicans will die from COVID-19.

Critically ill people, who have severe respiratory failure, will require treatment in intensive therapy with mechanical ventilatory support, that is, intubation. But, the percentage of people who could lose the battle against the disease is between 70 and 80%.

However, it is estimated that the maximum peak occurs between May 8-10, with “thousands” of new cases daily and the authorities have been preparing for months to deal with continence, said López-Gatell.
