Overview of system
exchange of C02 and 02 gases in the lungs.
What structure warms and filters the air? Along with trapping microorganisms and dust.
Air flows from high pressure to low pressure which then creates less pressure inside so everything moves down so that the air moves inward.
Air Pressure Variance
This happens when oxygen concentration is too high
Alveolar collapse
Musical noise
Wheezing
what type of pressure forces air to be drawn into the lungs and what is this process called.
Negative pressure; Inhalation
What is the function of the nerves in the nose?
Odor detection and to provoke sneezing
Airflow during inhalation and exhalation.
Airway resistance
This happens when too high of an oxygen flow therapy is given for too long.
Oxygen toxcity.
sounds like milk pouring over rice krispies or hair rubbing together and is an indicator of pneumonia
Crackles /Rales
Physical process of moving air in and out of lungs (also known as breathing)
Ventilation
Mucosal lined and ciliated ducts that are a prominent site of infection while helping with speech resonance.
Paranasal Sinuses
Tidal volume minus volume of air inhaled and exhaled in each breath.
Lung Volume
How can an physical 02 tank cause injury?
It is pressurized so can go off like a missle if mishandled.
If this bronchial noise is heard you can ask pt to cough and since its due to secretions the sound will shift.
Rhonci
level in which gas exchange takes place.
Alveoli
Known as the "watch dog" of the lungs and is the "voice box". Protects lower airway and facilitates cough.
Larynx
Osteo athritis and COPD can cause this ribs get stuck in expanded position. Ribcage anterior posterior (AP) diameter expansion.
Barrel Chest.
Why is it important to never smoke around an 02 tank.
02 is highly combustible must also place 02 in use signs.
This sounds like a creaking door caused by loss of lubricating fluid.
Pleural friction rub.
Physical abnormality of nail bed angle with spongy appearance due to chronic decreased oxygenation.
Clubbing
This structure connects the Larynx to the R and L Bronchi main stem.
Trachea
What increases airway resistance?
Asthma, bronchitis, mucus.
What disease puts the pt at higher risk for oxygen toxcity.
COPD
high pitched sounds during inspiration, emergent situation.
stridor
