What are the uses of ventilation?</h3>
The mechanical system in a structure that introduces "fresh" outdoor air and exhausts "contaminated" internal air is known as ventilation. In a workplace, ventilation is utilized to control exposure to airborne contaminants.
The indoor environment is kept healthy and fresh by adequate ventilation. Homes need to be able to breathe like lungs to ensure that clean air enters and stale air exits. High concentrations of moisture, smells, gases, dust, and other air contaminants can accumulate indoors. In general, the objective of ventilation in any occupied space is to supply the occupants with fresh air and expel heat produced in a small area. The ventilation system in healthcare institutions ought to aid in both illness prevention and patient care.
A critical condition that makes it challenging to breathe on your own is respiratory failure. When the lungs can't get enough oxygen into the blood, respiratory failure sets in. Our lungs take in oxygen from the outside air, and we exhale carbon dioxide, a waste product of the body's cells.
