MS1 Test2 Flashcards
Apnea
Complete absence of spontaneous ventilation
eupnea
Normal spontaneous breathing
Dyspnea
Difficulty breathing that the individual is unaware of it
Hyperpnea
Increased volume/depth of breathing w/ or w/o increased frequency
Bradypnea
Decrease respiratory rate
Tachypnea
Rapid rate of breathing
Orthopnea
Dyspnea which occurs when lying flat, causing the person to have to sleep propped up
Atelectasis
Pneumothorax
Air does not enter the pleura
Collapse of lung leads to medistinal shift to the side of collapse
Pneumothorax
Shifts away from the collapsed lung
Tension Pneumothorax
More and more air accumulates in the pleural cavity w/ each breath
Non tension pneumothorax
There is air in the pleural cavity but it does not accumulate w/ every breath
Spontaneous Pneumothorax
W/o blunt force trauma or medical procedure
Non-spontaneous pneumothorax
Arising due to blunt force trauma or medical procedure
Primary spontaneous pneumothorax
w/o existing lung pathology
Secondary spontaneous pneumothorax
Arising due to lung disease like COPD
Traumatic Pneumothorax
Blunt force traum, gun shot, car accident, knife stab
Iatrogenic pneumothorax
Trauma due to medical procedure i.e. Pacemaker insertion
Centrilobular Emphysema
Most common
Affects central portion
Central bronchioles are affected in superior part of lungs or lobes
Starts at the respiratory bronchioles and spreads peripherally.
Panacina emphysema
Destroys entire alveolus uniformly and is predominantly in the lower half of the lungs
Alpha 1 antitrypsin deficiency or Ritalin induced lung emphysema.
Ritalin
Treat ADHD
Block pulmonary vessels and elevate pulmonary BP
Symptoms similar to panacinar emphysema.
Tidal Volume
Volume of air inspired or expired w/ each breath
Dead Space Volume
The air which a person breathes but is not used for gas exchange.
It fills respiratory passages like the nose, pharynx and trachea
150 mL
Residual Volume
Amount of air in lungs which can’t be exhaled or pushed out of lungs.
1-2 L is normal
Total Lung Capacity
Volume of air in the lungs after maximal inspiratory effort
6000mL
