The respiratory system is one of the most vital systems in the body because it supplies the primary element that keeps everything going which is oxygen. First, we’ll be going through the anatomy and physiology, the pathophysiology, and the common diseases associated with the lungs. Then, we’ll tackle the two types of respiratory drugs which are categorized as the bronchodilator
Anaphylactic shock is a severe, life-threatening hypersensitivity reaction that occurs in response to exposure to an allergen. Anaphylactic shock pathophysiology involves both volume and resistance changes. Anaphylactic Shock Pathophysiology When an allergen enters the body, it activates mast cells and basophils, which release chemical mediators such as histamine, prostaglandins, and leukotrienes. These mediators cause vasodilation, increasing the volume of the
Vicodin is an opioid analgesic commonly used for severe pain. Vicodin is a popular drug that is usually abused in various settings, mostly by people who have been subjected to chronic pain. Opioid analgesic is Vicodin’s category due to its affectation on the opioid receptors in the brain. Vicodin and CNS The central nervous system is the brain and the
After going through the different kinds of volume depletion drugs, we’ll be discussing what beta-blockers are. Beta-blockers are commonly given to hypertensive clients to manipulate the conduction system of the heart. Decreasing Blood Pressure There are a couple of ways to lower blood pressure. First is taking off the workload by decreasing the fluid volume, through the use of diuretics
Hello. This is our third video focusing on the nervous system’s physiology, primarily giving a quick review of the sympathetic and parasympathetic nervous systems. Sympathetic Nervous System (SNS) The sympathetic nervous system mainly controls the fight and flight response, which, in layman’s terms, would be the system responsible for responding during a stressful situation. And the two main organs that
Blood pressure is determined by two factors – systolic and diastolic pressure. In this discussion, we’ll go through the traffic jam that happens within the blood vessels, the factors that influence pressure increase, and how peripheral pressure heightens. Jump to Sections Blood Pressure Systolic vs Diastolic Blood Pressure Pulse Pressure Narrowing Blood Pressure (The Traffic Jam) Think of your blood
Cerebrovascular accident (CVA) and transient ischemic attack (TIA) are conditions that occur due to a lack of oxygen in the brain. Therefore, knowing the differences between TIA vs CVA is crucial for patient care (and nursing exams). The most significant difference between the two is the presence of blood clots inside the brain. CVA results from the absence of oxygen,
