81
The space between the visceral and the parietal pleura =
The Pleural Cavity
82
The Pleural Cavity holds how much pleural fluid?
What does this fluid do?
~25 mL.
It lubricates membranes.
It also allows pleura to slide easily without friction, during respirations.
83
What are the types of pressure?
Intra-Pleural Pressure
Atmospheric Pressure
Intra-Thoracic (Intra-Pulmonic) Pressure
84
What is Intra-Pleural Pressure?
Normal Expansion.
Pressure in the Pleural Cavity, around the lungs.
85
What is Atmospheric Pressure?
The pressure outside the chest in the atmosphere
86
Intra-Thoracic (Intra-Pulmonic) Pressure
Pressure inside the lungs
87
You should have a negative or low pressure in the pleural space, so your Intra-Pleural pressure should be less pressure than-
Why?
The Atmospheric Pressure + Intra-Thoracic Pressure.
To allow room for the lungs to expand
88
What does positive or increased intra-pleural pressure do to the lungs?
Air goes into the intra-pleural space which causes a collapse of the lung (Which is called a Pneumothorax)
89
What is positive or increased intra-pleural pressure caused by?
This is caused by an open chest cavity like a stab wound or surgery
90
A Pneumothorax will have what effect on the lung?
Diminished / Absent Lung Sounds.
The respirations will be asymmetrical, there will be sharp pain, tachypnea, restlessness, and anxiety
91
How does a pneumothorax get treated?
A chest tube or a thoracentesis is done to remove the air, blood, and pus from the intra-pleural space
92
When you take a needle and go into the lung to remove air, blood, or pus, this is called a-
Thoracentesis
93
The lungs expand due to -
If this is changed then what happens?
The negative intra-pleural pressure.
The lung collapses (Pneumothorax).
94
What’s the difference between intra-pleural and intra-pulmonic?
Intra-pleural = In between the Pleura
Intra-Pulmonic = Inside the lung

Opening in the chest wall and Parietal Pluera (The outer lining of the pleura)
98
A pneumothorax with no external open wound =
Closed Pneumothorax
99
When does a Closed Pneumothorax occur?
When the Visceral Pleura is disrupted, this allows air to enter the pleural space through the lung
100
Exchange of respiratory gases (O2 & CO2) between the atmosphere and blood =
Oxygenation
101
What are the 3 steps of the oxygenation process?
Ventilation (Also called Pulmonary Ventilation or breathing)
Gas Exchange
Transport
102
Breathing, move gases in & out of lungs via inhalation and exhalation =
Ventilation
103
Diffusion of O2 & CO2 between alveoli & pulmonary capillaries =
Gas Exchange
104
O2 transported to organs and tissues + returns CO2 back to lungs for exhalation (returns deoxygenated blood to the lungs to the alveoli) =
Transport
105
The Diaphragm plays a big role in-
Ventilation, because it helps the lungs to expand
106
Deoxygenated blood gets to the alveoli via-
The Pulmonary Artery
107
Oxygenated blood gets to leave the alveoli via-
The Pulmonary Vein
108
Inspiration/Inhalation is a-
Active Process
109
Diaphragm contracts & moves downward = lungs expand =
More Lung Volume = Decreased Intra-Thoracic Pressure = Negative Intra-Pleural Pressure = air drawn in = O2 moves into lungs
110
Exhalation/Expiration is a-
Passive Process
111
The diaphragm relaxes (and moves back up) and the lungs recoil (return to their normal size) =
Less Lung Volume = Increased Intra-Thoracic Pressure = Positive Intra-Thoracic Pressure = air
flows out = CO2 moves out of lungs
112
Abnormal Ventilation = Lung Disease =
Extra Effort to Ventilate = Takes more energy to breath in/out
113

Age
121
What are all of the accessory muscles of respirations for pt’s with decreased lung compliance or elastic recoil?

The exchange of respiratory gases is also called-
Where does this occur at?

125
What factors create an Ineffective Diffusion?
Thickness of alveolar capillary membrane (Pulmonary Edema, Pulmonary Effusion)
