Discussion The results from the experiment demonstrate that respiratory frequency was higher and increased faster as exercise intensity increased in caffeinated individuals. The correlation between the independent (intensity of work rate) and dependent (respiratory frequency) variables for both the caffeinated and non-caffeinated groups was fairly good (R2 > 0.35) so there is some evidence that caffeine causes an increase in respiratory frequency. Tidal volume and alveolar ventilation were…

arterial blood gas volumes, pharmacology, and some of the test procedures. The concepts that are the most clear to me is the anatomy of the heart, most of the pathologies pertaining to the cardiovascular system, the pathology of the airway of the lungs, percussion and postural drainage procedures, airway clearance and coughing techniques, gait patterns and gait terminology, lower extremity joints, muscle receptors, and manual muscle test grades.…

The resonatory system includes the nasal cavity and soft palate and portions of the anatomically defined respiratory and digestive systems. (Seikel, King, & Drumright, 2010). One disorder that may affect a person’s ability to use the resonatory system to produce sufficient speech is velopharyngeal insufficiency, or VPI. This is a disorder which results in the improper closure of the velopharyngeal sphincter (soft palate muscle in the mouth) during speech, allowing air to escape through the nose…

It test how well you inhale and exhale, and it also test how much air your lungs take in with each breath. To perform this test, an instrument called a spirometer is used which measures the volume of air moving in and out of the lungs during pulmonary ventilation. When given this test a person can be standing up or sitting down but whichever one that person must remain in that position throughout the whole test. The person cannot change positions because that will mess of the results from the…

number has steadily gone up since then. Out of those forty eight million, 7.3 million were for the heart. That means that six of every ten surgeries are for the heart (“data”). The type of surgeon that studies and performs surgeries on the heart and lungs is called a cardiothoracic surgeon. As cardiothoracics (cardio) grows, there happened to be a point when it was not commonly known. Since cardio was not commonly known, more and more people were learning about it to see if they could improve…

is the main cause of pulmonary emphysema with signs and symptoms, including dyspnea on exertion, cough with scant mucus, weight loss, tachypnea, end- expiratory wheezes, use of accessory muscle, barrel chest, pursed lip breathing, and hyperresonant lung sound. These clinical manifestations have been seen or reported during Mason’s physical examination confirming his diagnosis…

Cilia and the Protection of the Respiratory Tract Introduction Approximately twelve thousand litres of air is inhaled by one person each day containing environmental stimuli including pathogens and particles such as toxic pollutants and allergens. These must be expelled from the body as it may induce airway inflammation and infection, causing airway diseases. Mucociliary clearance acts as an innate defence against these stimuli, where cilia is a part of this mechanism. Cilia, microscopic…

reversible airflow obstruction and an abnormal inflammatory response in the lungs (MacNee, 2006). In many peer research articles, the articles have addressed the diagnosis and assessments of people with COPD, as well as the pharmacological and the non-pharmacological management of stable disease and exacerbations. Chronic obstructive pulmonary disease is characterized by chronic inflammation of the airways, tissue of the lungs and pulmonary blood vessels. These obstruction’s are caused by…

as the tissues between air sacs are destroyed and air pockets in the lungs form as a result. The air is then trapped in the damaged lung tissue. After the air is trapped, the lungs begin to enlarge and breathing then requires more effort. The inner walls of the air sacs weaken and eventually rupture with emphysema. This rupture causes one large air space instead of many small air spaces. This reduces the surface area of the lungs and also reduces the amount of oxygen that reaches the…

This could cause a build-up of CO2 in the body, lowered amounts of oxygen. Eventually after so many exacerbations and chronic COPD, we might see heart changes because the lungs are not going to keep up with the body’s preload demands. Expected signs/symptoms/labs/diagnostic tests -Chest x-ray show infiltrates that could indicate infection, sputum culture positive -ABG show increased CO2, decreased PO2, decreased pH, and…
