How novel coronavirus kill us?what is acute respiratory distress syndrome(ARDS)

RDS(Respiratory distress syndrome) and influenza virus cause ARDS(acute respiratory distress syndrome).These viruses always infect. I am going to explain it briefly.

How it infect lungs?

Before we read about its infection. we should known about anatomy of lungs.

Lungs anatomy

Lungs anatomy is same like tree ,stem, branches and small branches with leaves.

same lungs Start with larynx divide into two bronchus than these bronchus further divide into more small parts called bronchioles and the last part is alveoli.

Alveoli is last part of bronchus where the exchanging of gases deoxygenated blood present in blood capillaries near to alveoli.so oxygen present in alveoli defused into blood capillaries and carbon dioxide defuse into alveoli inner membrane space.

So oxygenated blood than goes to heart and than supplied to whole body.

So we continuously taking oxygen into the body and carbon dioxide outside from the body through nose and mouth.

Viral infection and its side effect on lungs.

Virus have two pathway to inter into our body is mouth and nose.

Viral Intery through mouth:

If virus inter through mouth so very less chance it would inter into our lungs ,if we drink water again and again so it would go into our stomach with water. So stomach is acidic environment, so it would kill virus over there. This is the main reason doctor suggest to drink more and more water to citizen to prevent against virual infection.

Viral Intery through nose:

If virus inter through nose,so i would directly infect our lungs and cause ARDS(acute respiratory distress syndrome).

But some 2019 novel coronavirus and influenza virus cause pneumonia in some patients instead of ARDS(acute respiratory distress syndrome)

Novel coronavirus when infect, it damage entire lung not it's some part!

How it damage?

When virus infect it cause inflammation.In result of inflammation the proteinous fluid inter from blood capillaries to alveoli and block the way of oxygen . So exchanging of gases not occur so cause hard breathing. The wall of alveoli shrink and the inner space of the alveoli reduce and cause ARDS. This condition called hypoxic.

During this condition,we keept the patient in ventilator and supply oxygen by ventilator machine untill that fluid not come back into blood capillaries and leave the alveoli. And breathing improve when patient on ventilator.

This is how viruses infect us and cause hard breathing problem and in acute respiratory distress syndrome most of patients died because of hard breathing problems.

So how we manage to maintain normal breathing of a infacted person

If we put the patient in ventilator so inflammation is increase.So we make sure to apply enough pressure to prevent alveoli from inflammation and small amount of tidal volume to ventilate that patient. But in results less carbon dioxide move outside but we don't care we need to prevent patient from more inflammation and keep alveoli open.

So second we have problem is that when carbon dioxide move outside slowly so gradually its pressure increase inside the lungs and cause low blood pressure and blood clotting. So to solve this issue by paralysing strategy.

Third solution is that we put the patient in belly down position called prone positioning and flow of breathing maintain at great extant

Concussion!

By doing these strategy ,we can save most of patients but in reality doctor is source of hope.

This update is to make sure that people should understand medical background , that what going on and how we are fighting with Covid-19.

All of us should take part to make sure our society , country and world free of this disaster. We all need to work together. Always do precautions against novel coronavirus.This is your responsibilty.

Thanks for your pricious time and for reading.Hope you would enjoy and Stay tunned for more !
