The Airways and Alveoli
These airways connect atmospheric air with the gas exchange membrane of the lungs.
What are the conducting airways?
This is the space between the lungs containing the heart, aorta, esophagus, great veins, trachea, and mainstem bronchi?
Atmospheric pressure is how many mm Hg at sea level?
What is 760mm Hg?
If PaCO2 is above normal.
What is hypercapnia?
This is the highest instantaneous flow achieved during an FVC maneuver?
What is Peak Expiratory Flow (PEF)?
The mucus secreting epithelium is called the Respiratory...?
What is the respiratory mucosa?
What is the diaphragm?
This is a graphical record of lung volumes made by a spirometer?
What is a spirogram?
If PaCo2 is below normal.
What is hypocapnia?
The expiratory and inspiratory portions of the flow volume graph form a loop, called the?
What is the flow volume loop?
This medical procedure involves the insertion of an artificial airway through the nose or mouth and into the trachea?
What is intubation?
A thing anterior portion of the upper lobe of the left lung overlaps the heart and continues downward to a narrow point, forming the what?
What is the lingula?
The amount of air in the lungs at the point of ventilatory muscle relaxation, also known as the resting point, or end tidal exhalation level.
What is FRC?
This refers to the PCO2 changes of exhaled Vt's graphically displayed as a waveform.
What is capnography?
What is maximum voluntary ventilation (MVV)?
The space behind the nasal cavities that extends down behind the tongue to the larynx?
What is the Pharynx?
This is attached to the lungs surface. it doubles back on itself at the hilar region and continues as the parietal pleura on the inner surface of the chest wall?
Expiratory muscle contraction is required to exhale any portion of the FRC, which involves exhalation of the?
What is the expiratory reserve volume? (ERV)
A device used in the clinical setting to analyze exhaled CO2?
What is a capnometer?
The maximum voluntary hyperventilation sustainable for 10 to 15 minutes.
What is the maximum sustainable ventilation (MSV)?
The tubes allow pressure equalization between the middle ear and atmosphere? They are also called the auditory tubes.
What are the eustachian tubes?
The lowest margin of the diaphragm meets the chest wall in an area called the?
What is the costophrenic recess?
These measurements depend on ventilatory muscle strength?
What is the MIP and MEP?
This allows the PCO2 to be identified at the end of a tidal exhalation which corresponds to average PACO2.
What is a Capnogram?
Airways less than 2 mm in diameter, beginning around the eighth generation of airway subdivision and extending to the acinus.
What are the small airways?
Mechanically ventilated patients in whom endotracheal intubation is required are susceptible to the development of lung infections known as?
What is Ventilator associated pneumonia (VAP)?
The voluntary skeletal muscles of the chest wall and diaphragm are innervated by the?
What is the somatic nervous system?
This law states that an elastic structure changes dimensions in direct proportion to the amount of force applied.
What is Hooke's Law?
What is the Bohr equation?
This uses an audio loudspeaker to apply alternating or oscillating pressures in the form of sound waves to the airways during tidal breathing.
What is Impulse Oscillometry (IOS)?
