Airway
What are the four parts of the upper airway?
- Nose
- Oral Cavity
- Pharynx
- Larynx
There are two types of airways. What are they?
- Cartiliaginous
-Noncartilaginous
What are the two major types of tissue in the lungs? And what is the function of each?
- Pseudostratified Columnar Ciliated Epithelium: Produces mucus as cilia (Nose and Bronchi)
- Simple Squamous Epithelial: Thin, easy absorption (Alveolar ducts and sacs)- Actual respiratory aspect
The oral cavity is assessed using what?
The Mallampati Scale
There are two ZONES. What are they?
-Conducting zone
- Respiratory zone
Give the 3 types of alveolar cells and why we need them
Type 1: Simple squamous (95% of lung cells)
Type 2: Septal cells- Produce surfactant around 28 weeks gestation
Type 3: Macrophages- Engulf bad things to dump them; Immune system
Space between the vocal cords is called..
Glottis
Name the structures located in the conducting zone and their generations
- Trachea (0)
-Main stem bronchi (1)
- Lobar bronchi (2)
- Segmental bronchi (3)
- Subsegmantal bronchi (4-9)
- Bronchioles (10-15)
- Terminal bronchioles (16-19)
Explain what makes the blood in pulmonary arteries and veins different from the blood in the rest of the arteries and veins in our bodies.
- The pulmonary arteries contain deoxygenated blood and the veins oxygenated blood
Four functions of the upper airway
-Pathway for air
- Humidify, Warm, and Filter
- Provide speech and smell
- Prevents aspiration
Name the structures of the respiratory zone and their generations
- Respiratory bronchioles (20-23)
- Alveolar ducts (24-27)
- Alveolar sacs (28)
This is located at the base of the trachea and splits the bronchi into left and right..
The carina
Pathway of air in order...
- Nares
- Nasopharynx
- Eustachian Tubes (Pharyngotympanic tube)
- Laryngopharynx
What do you do to keep a patient with Epiglotitis or LTB
- Give O2 if necessary
- Cool Bland Aerosol- LVN
- Keep SpO2 at 92% >
