The mechanics of breathing are what allows the body to inhale air containing oxygen, exchange this oxygen for carbon dioxide in the lung tissue and exhale the carbon dioxide which is a byproduct of energy consumption and metabolism. These mechanisms, if disrupted, can lead to life threatening complications as the body requires this exchange to survive. Understanding the mechanics of breathing sets the foundation to understanding how the body works and sustains life.  \nLearning objectives  \nBy the end of this module, you should be able to...  \n‣ Define Boyle’s law and understand how it applies to breathing  \n‣ Identify and define the different pressures that control breathing  \n‣ List the events that take place during inhalation and exhalation ‣ Define the Hering Breur reflex and the part it plays in preventing lung injury ‣ Define and Identify the different lung volume measurements  \nBoyle’s Law  \nBoyle’s Law states: the volume of an ideal gas is   proportional to the pressure of the gas.  \nBoyle’s law requires that the gas is held at a constant temperature  \nBoyle’s law: Decrease in volume = Increase in pressure  \nBoyle’s law: Increase in volume = Decrease in pressure  \nRespiratory Pressures  \n‣ Atmospheric pressure: the pressure of gases outside of the body  \n‣ Intrathoracic pressure (also called   pressure): the pressure of gases inside the thorax  \n‣ Intrapulmonary pressure: the pressure of gases in the    \nGases move from areas of high pressure to areas of   pressure  \nInhalation and Exhalation  \nInhalation:  \n‣ Thoracic muscles contract  \n‣ Intrathroacic volume    \n‣ Intrathroacic   decreases ‣ Air move into lungs  \nExhalation:  \n‣ Thoracic muscles relax  \n‣ Intrathoracic   decreases  \n‣ Intrathoracic pressure  ‣ Air moves out of lungs  \nChemical and Neural Respiratory Pathways  \nMain neural pathway controlling respiration = Hering Breur reflex  \nHering Breur reflex: reflex triggered to prevent   of lungs  \nMain chemical pathway controlling respiration (choose one)  \na. Oxygen  \nb. Carbon dioxide  \nc. Nitrogen  \nd. Carbon monoxide  \nIncrease in CO2 triggers increase in breathing rate (to blow off the excess CO2) Decrease in CO2 trigger decrease in breathing rate ( to retain CO2)  \nLung volumes  \nLung volume measurements  \n1. Tidal volume  \n‣ Volume of air inhaled and exhaled in a normal breath  \n2. Inspiratory reserve volume  \n‣ Volume of air that can be forcibly inhaled beyond a normal breath  \n3. Expiratory reserve volume  \n‣ Volume of air that can be forcibly exhaled after a normal breath  \n4. Residual volume  \n‣ Volume of air left in alveoli after forcibly exhaling  \n5. Vital capacity  \n‣ Inspiratory Reserve Volume +   + Tidal volume  \n6. Total lung volume  \n‣ Vital capacity +    \nNormal Tidal Volume = 500ml  \nHIGH YIELD REVIEW  \n‣ Boyle’s law: volume of gas is inversely proportional to pressure  \n‣ Gases flow from areas of high pressure to areas of low pressure  \n‣ When atmospheric pressure exceeds intrathoracic pressure, air flows into the lung ‣ When intrathoracic pressure exceeds atmospheric pressure, air flow out of the lungs ‣ Hering-Breuer reflex prevents overinflation of lungs during inahlation  \n‣ CO2 is the main chemical that stimulates respiration (NOT O2!!)  \n‣ Normal tidal volume = 500ml  \nAIRWAY ASSESSMENT  \nAs with all things in medicine, a good assessment is what sets the stage for appropriate diagnosis and treatments. Airway emergencies are some of the most common emergencies seen by first responders and carry high morbidity and mortality if not addressed rapidly. In order to properly intervene to stabilize or protect an airway, you must be able to assess the airway quickly and efficiently.
