(Upper Airway Anatomy)
The major functions of the upper airway are these.
Warm, filter and humidify.
This lines the inside of the thoracic cavity.
Parietal Pleura
Secondary drive stimulated when arterial O2 levels fall.
Hypoxic Drive
The active, muscular part of breathing.
Inhalation
Acceptable range for ETCO2
35-45 mmHg
Bony shelves at the back of the nasopharynx that can cause substantial bleeding if a NPA is placed incorrectly.
Turbinates
Conduit for air entry into the lungs.
Trachea
A deficiency in arterial blood.
Hypoxemia
The process of loading O2 molecules onto hemoglobin.
Oxygenation
General range of PEEP setting for CPAP
5.0-10.0 cm H2O
Found at the posterior aspect of the oral cavity.
Oropharynx
Thin hollow tubes made of smooth muscle.
Bronchioles
This contributes to most abnormalities in O2 and CO2 exchange.
V/Q Mismatch
The exchange of gases in the alveoli.
Respiration
**Double points for the 2 gases and the location of the gas exchange**
A single lumen, cuffed airway that is blindly inserted into the esophagus.
King LT Airway
The narrowest portion of the adult trachea.
Glottic Opening
The substance that lines the alveoli.
Surfactant
The respiratory state in which pH of the blood is too high and respirations may be slow and/or shallow.
Respiratory alkalosis
The end product of the Krebs cycle and oxidative phosphorylation.
ATP (Adenosine Triphosphate)
This maneuver is used to open the airway in preparation for i-Gel insertion.
The tongue-jaw lift maneuver.
Fractures of certain sinus bones may cause a leakage of this into the nasal passages and auditory canal.
CSF (Cerebrospinal Fluid)
The space between the lungs that contains the heart, great vessels, esophagus, trachea, etc.
Mediastinum
The amount of gas in air or dissolved fluid, such as blood.
Partial Pressure
The feedback loop that terminates inhalation to prevent overexpansion of the lungs.
Hering-Breuer reflex
Damage to the cellular tissue as a result of excessive O2 levels in the blood.
Oxygen Toxicity
