50
What are the 3 types of pressure measurements
1. Intra-compartmental 2. Transmural 3. Driving
51
Intra-compartmental pressure measurment
Pressure within a space
52
Transmural pressure measurement
Pressure difference acting across a wall or membrane
53
Driving pressure measurement
Difference in pressure between two end of an open system responsible for flow
54
What are the 7 different respiratory pressures?
55
What is transdiaphragmatic pressure (Pdi)
Pressure generated across the diaphragm during inspiration
56
What are the 4 principles of the kinetic molecular theory
1. Particles are in constant motion (collisions exert pressure) 2. No attraction or repulsions 3. More space than particles 4. Particles move faster with increased temperatures
57
Describe Boyle's Law
Pressure and volume have an inverse relationship
58
Inspiration is [active/passive] and why?
Active because muscle contraction displaces respiratory system to change the volume in the lungs by creating a driving pressure for air to move into the lungs
59
Expiration is [active/passive] and why?
Passive (quiet breathing) because the system relaxes causing lung volume to decrease creating a driving pressure for air to move out of the lungs
60
A
61
What is negative pressure breathing
When expanding rib cage and contracting diaphragm during inspiration it pulls lung opens drawing air in because pressure in lungs is lower than atmospheric pressure. When contracting the chest and relaxing the diaphragm during expiration it decreases lung size releasing air because the pressure in the lungs is higher than atmospheric pressure.
62
Describe inspiration (quiet breathing)
63
Describe expiration (quiet breathing)
64
Describe at rest (quiet breathing)
65
What are the 4 fundamental properties of quiet breathing at respiratory position?
1. Lungs recoil inwards (always want to collapse) 2. Chest recoils outwards (always wants to recoil out) 3. Normally equal in magnitude and opposite in direction 4. Creates a vacuum in the pleural space
66
How many dimensions does the thoracic cavity expand
3-D
67
How do the upper ribs 1-4 move
Pump handle movement (anteroposterior expansion)
68
How do lower ribs 7-10 move
Bucket handle movement (lateral expansion)
69
How do ribs 5 and 6 move?
Combination of bucket hand and pump handle movement
70
How do the lungs increase vertically during expansion
By the diaphragm contracting and pushing down on the abdominal organs
71
What are 5 characteristics of ribs 7-10 movement during breathing
72
What are 5 characteristics of ribs 1-4 movement during breathing
