Ch.29, 30 Flashcards
Why does a problem with the right lung interfere with oxygenation to a greater degree than a problem in the left lung?
The right lung, is larger than the left, and is divided into three lobes. The left lung is smaller to make room for the heart. About 60% to 65% of respiratory function occurs in the right lung
Atelectasis
Collapse of the alveoli
Why are women more at risk for rapid decline and lung function as an older dog then men?
Women, especially smokers, have greater bronchial responsiveness and larger airways then men.Women have more rapid decline as they get older, especially and people who smoke
Dyspnea
Shortness of breath
Hemoptysis
Blood in the sputum
Orthopnea
A shortness of breath that occurs when laying down but is relieved by sitting up
Pneumothorax
Air in the plural cavity
What made it mean if tactile fremitus is decreased
If the transmission of sound waves from the larynx to the chest wall is slowed. This problem can occur when the plural space is filled with air (pneumothorax) or fluid (pleural effusion) or when the bronchus is obstructed.
What may it mean if the tactile fremitus is increased
Pneumoniabecause they increase the density of the thorax and enhance transmission of the vibrations
FVC Forced Vital Capacity
Maximum amount of air that can be exhaled as quickly as possible after maximum inspiration
RV Residual Volume
Amount of air left in the lungs after the end of a forced exhalation
Hypoxemia
Low levels of oxygen in the blood
Hypoxia
Decreased tissue oxygenation
Clients with COPD have high levels of CO2 called CO2 narcosis. What is their stimulus to breath?
Stimulus to breathe is a decreased arterial oxygen level. Known as the hypoxic drive to breath
What are the low flow oxygen delivery systems?
Nasal Cannula
Simple Facemask
Partial Rebreather Mask
non-rebreather mask
