Applications of Boy’s Law in Iron Lung Machine

1 Applications of Boy’s Law in Iron Lung Machine The iron lung is a negative ventilator machine that usually mimics human chest muscles and diaphragms to improve the gas exchange. To understand how the machine works, two concepts are applied; pressure gradient is applied, which states that gases' equilibrium to be achieved gases move from high pressure areas to low pressure. Boyle's law is also applied; the gas law explains the relationship between pressure and volume (Sattari et al.2020). The machine is used as a ventilation device for polio patients who cannot breathe because the virus has paralyzed their chest muscles, also used by patients with chronic obstructive pulmonary disease and respiratory failure to improve gaseous exchange (Harrington, 2019).

Boy’s gas law is used to design the machine as human lungs are thought to be containers of gases. The law states that when temperature and volume are equal, the pressure is inversely proportional to the volume. The machine applies this law by creating a vacuum, which generates a negative pressure that causes the chest to expand and reduces intrapulmonary pressure that allows ambient air to flow into the lungs during inhalation (Baker, 2016).

2 During exhalation, the machine relaxes the diaphragm causing pressure in the iron lung to increase, and the chest volume becomes smaller, allowing the air to flow out. Air moves out of the lungs until an equilibrium is achieved between the atmospheric and intrapulmonary pressure.

In summary, the iron lung machine applies the Boy's law of gases where the pressure is inversely proportional to the volume. The pressure increases with a decrease in volume, causing air to be expelled out, and when the pressure decreases, the volume increased and the airflow into the lungs.
