asthma is a chronic inflammatory disorder in the major Pathways of the lungs the broni and the bronchioles when these guys get inflamed it's called Bronco constriction since the bronchi constrict down and get tight unlike COPD which is irreversible resulting from long-term chronic damage mainly to the alvioli and broni like from years of smoking or other inhaled toxins as is very different in that it comes and goes with flareups in the form of asthma attacks now these are reversible another key difference is that only the broni are involved here and not the alvioli and it typically does not cause long-term damage so think of the Double A's a for asthma a for acute attacks that can come and go typically triggered by anything that can irritate those sensitive bronchi like cigarette smoke pollen dust strenuous activity and even cold weather but we'll talk about the triggers later in a moment whatever the cause during the asthma attack two key things happen first the broni puff up with inflammation and get very tight again this is called Bronco constriction and secondly the body secretes excessive mucus from the goblet cells that line the respiratory tract resulting in wet mucus filled lungs now this is super super deadly since the respiratory tract gets so constricted closing off any and all oxygen to the alvioli this means no oxygen in so we get decreased inhalation and no CO2 that carbon dioxide out resulting in air trapping making it hard to Exhale now this leads to acidosis in the body which could lead to deadly respiratory failure now in terms of the signs and symptoms we use the acronym asthma and a little tip here focus on the highlighted ones below since these were the most tested out of five different exam question Banks so A is for accessory muscle use due to the increased work of trying to breathe and a key critical sign here is paradoxical breathing write that one down it's very deadly this indicates diaphragm muscle fatigue and a little enlex tip here focus on the most deadly least signs since these are the most tested signs s is for shortness of breath and dpia that difficulty breathing and a critical sign here is single word dpia T is for tight chest and tacpen that fast respiratory rate so just think about it here air trapping in those inflamed lungs lead to tacpen a rapid respiratory rate you're unable to take a full deep breath H is for high pitched wheezing probably the most classic sign of an asthma attack hey everyone nurse Mike here from simplenursing.com did you get your beautifully handcrafted study guide bundle yet it highlights the key points and memory tricks in this video plus get 900 more videos not here on YouTube all neatly organized in the playlist along with thousands of practice questions written by actual enlex writers so don't be scared be prepared try it free today visit simplenursing.com it sounds like a whistle due to that inflammation causing narrowed Airways sounding a lot like this M is for minimal diminished breath sounds now this next part you need to write down the Key signs for deadly respiratory failure and deadly status asthmaticus just think of the Three A's here so our first A is for absent breath sounds this is known as a silent chest now this is priority write this down on exams and the boards if your patient suddenly stops wheezing during an asthma attack this is not a good sign the enlex will not suddenly cure your patient for you so exams won't give you a cured patient this typically means that the lungs are puffed up so much and get so tight that it completely cuts off St all oxygen and air flow leading to the last two A's here acidosis that CO2 retention and air trapping so we get prolonged exhalation write that down prolonged exhalation now don't get tricked here not prolonged inhalation we see the key term once again prolonged exhalation breathing out so just think of the pathway here we have inflamed lungs right so we can't get oxygen in we have short inhalation not prolonged and you can't get Co2 that carbon dioxide out so the key term prolonged or longer exhalation that air exiting the body so in result CO2 builds up in the body causing acidosis from that carbon di acid that carbon dioxide all right that wraps it up thank you so much for watching don't forget to take your quiz and download the study guides and also feel free to share the love share with a classmate and even your instructor see you guys in the next videos
