What is the ventilator

What are these ventilators, we also call them respirators? These are mechanical devices that help a patient breathe when they are unable to do so on their own. If I were to ask you, what do we breathe? We breathe in air. But this air is only 21% oxygen. What this ventilator does, it takes this compressed gas oxygen and mixes it with other gases. These ventilators. They allow you to artificially push in the certain required amount of oxygen into the patient's lungs, and then these patients can breathe. But the question you might be asking is, why do we need ventilators for COVIT19 patients in extreme cases, these patients Suffering from COVID19. They also have interstitial pneumonia, which means this virus, causes inflammation were in these bronchioles. Now, what are these bronchioles? These are basically air passages inside your lungs. inflammation is caused not only in these bronchioles but also in alveoli and what are these alveoli? These are tiny sucks to which the air is delivered. So when there is inflammation in alveoli as well as bronchioles, it basically means air cannot get in or get out of the lungs, which means the patients will have to work harder to breathe. This is where the ventilator is used. So what this ventilator does, mechanically it pushes the compressed gas, oxygen, and other gases into the lungs so that the patient is in a position to breathe in and breathe out.

How lockdown having a disproportionate impact on women

A disaster or catastrophic ends to have a disproportionate impact on women. According to the writer, this is because of the traditional gender-based role of women in society. For example, during the 2004 Indian Ocean tsunami, it was observed that the disaster had a disproportionate impact on women, mainly because of their gender-defined roles. Since women are generally seen as the traditional caregiver in the family, they lacked the required life-saving skills, and as a result, a relatively higher number of deaths count was registered amongst women during the tsunami. Then after the disaster, women who were rendered homeless were accommodated in relief camps. And it was observed that at these relief camps, women had to face abuse and molestation, and they even had to face hygiene and sanitation issues at these relief camps. similar challenges have been faced by women in the United States as well, which is frequently hit by tornadoes. similar challenges were noted during the 2018 19 f…

Are humans responsible for the COVID-19 pandemic

Humans responsible for the pandemic According to the UNDP. The spread of a zoonotic disease such as COVID-19 can be directly attributed to the overexploitation of biodiversity and ecosystems by human beings. The UNDP has said that several zoonotic diseases have affected human beings because of increased contact of humans with animals. Especially wild animals. So these diseases with a jump from animals to human beings are referred to as zoonotic diseases or zoonosis. And it is a direct outcome of the overexploitation of biodiversity and ecosystems through human activities. The UNDP report even says that it is not just COVID-19 but even tuberculosis, rabies, malaria, toxoplasmosis h1 none SARS, burst, Ebola Zika, etc. They are all examples of zoonosis that have jumped from animals to human beings. And in each case, the source can be attributed to the destruction of the environment and biodiversity through human activities
It is found that the coronavirus outbreak certainly comes from t…

Researchers found new symptoms of COVID19

Many COVID-19 cases have emerged from Europe and the United States, where many patients have reported a complete inability to smell or even to taste. So, this has given rise to questions, whether the SARS coronavirus is affecting our neurons that are responsible for smell and taste, or is it affecting other cells, which are involved in this olfactory function. A recent study conducted in India has shown that it is not the neurons that are being affected by the virus, but instead, it is a set of cells present in the upper regions of our nasal cavity that are being affected by the double Coronavirus. These cells include the sub Technicolor cells and the horizontal basal cells. But importantly, these cells are not directly involved in helping us smell. It means that these cells are not directly involved in the olfactory function. But these cells help us nourish and support the other cells, which are actually involved in the olfactory function. So this means that the novel Coronavirus is…
