The business of breathing

  • A large number of ventilators may potentially be required soon, and the Railways-owned Integral Coach Factory (ICF) has made an attempt to “reverse engineer” the machines. Private sector carmakers with no experience in this line too, have joined the task.
  • Ventilators (or respirators) are mechanical devices that help a patient breathe when they are unable to do so on their own. Hospitals have a supply system for gases like oxygen, which are used in ventilators.
  • The ventilator takes the compressed gas (oxygen) and mixes it with other gases (because typically what we breathe is 21% oxygen from the atmosphere). It allows you to artificially push in a certain required amount of oxygen into the patient’s lungs and allows them to deflate.
