Step-by-Step Solution:1. Understanding the Composition of Air: - Air is composed of various gases, primarily nitrogen (about 78%) and oxygen (about 21%), along with small amounts of other gases like carbon
The percentage of nitrogen in inhaled air is \rule{1in}{.2mm} % and exhaled air is \rule{1in}{.2mm} %. What is the percentage of nitrogen in the air we breathe? The appropriate amount of oxygen in the air is (a) 21 percentage (b) 50 percentage (c) 35 percenta...

Mixed Pressure Control Innovation of Oxygen and Air Pressure in Ventilator with Safety Valve The medical gas in the ventilator is very influential in maintaining patient survival so that the gas must be sterile, have high purity and have a stable pressure, with a value of no more than 5 bars...
A setting unit (16a) determines the difference in pressure at the sides of the membrane. The membrane has a higher permeability for oxygen than for nitrogen, and preferably only allows oxygen to pass through it, with a lower pressure on the motor intake side than at the air flow side....
