Question

What is the correlation between positive pressure ventilation and incomplete ventilation?

Answer 1

Positive pressure ventilation is a process of respiration in which the air is gulped and forced down the respiratory system to the lungs. A ventilation is generated by means of maintaining a positive pressure of air which is considered to be above the external pressure of air in a given space.

Incomplete ventilation in a given space refers to the movement of air in the ventilation which does not get to complete its cycle that starts from the intake till the exhaustion in a given space.

They are both different phenomenon and so, it is difficult to give an answer that depicts its correlation.

Answer 2

There are two main types of mechanical ventilation present in the system namely the positive pressure ventilation in where the air or another gas mix is pushed into the lungs through the airways and the negative pressure ventilation, where air is sucked into the lungs by stimulating movement of the chest. Positive pressure ventilators work by increase of the  airway pressure through an endotracheal or tracheostomy tube.
