Gas exchange asthma - Study guides, Class notes & Summaries

Portage learning Pathophysiology exam 5 is a complete document that contains all likely exam questions that could appear on exam 5. The Portage Learning Pathophysiology Exam 5 typically covers material related to pulmonary system disorders, including asthma, COPD, and other respiratory conditions. It assesses understanding of the physiological processes behind these conditions, as well as how the body compensates during respiratory distress. Topics may include the mechanics of breathing, gas ex...

V/Q mismatch ~~> Ventilation/perfusion ratio (V/Q ratio) is a ratio used to assess the efficiency and adequacy of the matching of two variables = ventilation (V) and perfusion (P) Mechanical insufficiency ~~> Structural damage- Nervous System (alter resp rate and depth), Muscles (Abdo, intercoastal, diaphragm- (impact intrathoracic vol= dec pressure to exchange air), Airway obstruction- physiological and foreign objects (inflammation, obstructions) Medication- CNS Depressa...

Asthma attack triggers can include airborne irritants, respiratory illness, or strenuous exercise. -During an asthma attack, airway muscles tighten, the airways swell and inflame, and excess mucus is produced. ...

NR 507 Pathophysiology Latest Version Already Passed Oxygen transportation step 1 Air is inhaled through the process of ventilation (mechanical movement of gas or air into or out of the lungs) Oxygen transportation step 2 oxygen diffused from the alveoli into pulmonary capillaries, moving oxygen from the pulmonary veins to the left side of the heart to the aorta into systemic arterial circulation Oxygen transportation step 3 Perfusion (exchange of O2 and CO2 in the blood stream, which occurs v...

emphysema and fick's equation - airway obstruction as a result of inorganic particles --> triggers the production of elastase which breaks down elastin --> alveoli lose elastance --> alveoli recoil --> increase in T and decrease in A --> lower gas exchange inspired partial pressure - Pi,o2 = Fo2 * (Patm - Ph2o) air conditioning during inhalation: adds warmth and moisture to the gas --> water gets evaporated in the mucosa, generating a water pressure which decreases the at...
