Gas Exchange Flashcards
There are three organ systems related to Gas Exchange. Give them all.
- Respiratory System
- Cardiovascular System
- Hematologic System
YES OR NO - the ff. gas exchange terms are matched correctly
Perfusion - CO2 and O2 exchange at air-blood interface
Diffusion - gas exchange of atmospheric air and blood
Respiration - the blood flow in the pulmonary circulation
Ventilation - the inflow and outflow of gas from the lungs
NO - the ff. are not correctly matched
Perfusion - the blood flow in the pulmonary circulation
Diffusion - CO2 and O2 exchange at air-blood interface
Respiration - gas exchange of atmospheric air and blood
Ventilation - the inflow and outflow of gas from the lungs
It is the mechanism in which there is gas exchange alveolar and pulmonary capillary blood.
Simple Diffusion
Hypoxia - low oxygen level for tissue: Hypoxemia - _______
low blood oxygen saturation
Why do patients with gas exchange problems cough?
- Increased mucus production
- Obstructions
- Aspiration
Inflammatory processes as well as viral and bacterial infections may cause an increase in ____________.
Sputum production
It is characterized by having bloody sputum and may signify an infection inside the lungs.
Hemoptysis
It is characterized by difficulty in breathing and may be a sign of gas exchange and/or heart problems.
Dyspnea
What does COPD stand for?
Chronic Obstructive Pulmonary Disease
It is the greatest risk factor associated with COPD.
Smoking
Chronic bronchitis is diagnosed when there is _____________________.
Cough and sputum production for at least three (3) months within two (2) consecutive years
Characterized by abnormal distension of air spaces beyond the terminal bronchioles along with alveolar wall destruction. There is also some jugular vein distention and liver involvement because of high hepatic portal circulation.
Emphysema
These are bronchial spasms caused by allergens and/or stress manifested as wheezing, chronic cough, prolonged expiration, and dyspnea.
Bronchial Asthma
Pneumonia is an inflammatory disease which may be ___________ or _________. This condition mostly affects individuals who are ______________. Its signs and symptoms are mostly composed of the typical response to an inflammatory process like fever and an onset of chills.
- Typical - bacterial
- Atypical - inflammation of interstitial spaces
- Immunocompromised
TRUE OR FALSE
Mycobacterium tubercolosis is the main bacterial agent of tuberculosis which only affects the respiratory system. It is transmitted by means of touch.
FALSE
Mycobacterium tubercolosis is the main bacterial agent of tuberculosis but the disease is not restricted only to the respiratory system as it may also spread to other areas like the nervous system. It is transmitted by the sputum of infected individuals.
