Intrapleural pressure -✓✓The pressure in the potential space between the parietal
and visceral pleurae
The plateau pressure (alveolar pressure) is measured.. -✓✓During a breath hold
maneuver during mechanical ventilation, the value is read from the ventilator
manometer
Two types of forces opposing inflation of the lungs -✓✓elastic and frictional
forces
Two factors that result from frictional forces -✓✓The resistance of the tissues and
organs as they become displaced during breathing and the resistance to gas flow
through the airways
Compliance measurements are used to describe -✓✓Elastic forces that oppose lung
inflation
Airway resistance is a measurement of -✓✓Frictional forces that must be
overcome during breathing
The resistance to airflow through the conductive airways (flow resistance) depends
on -✓✓Gas viscosity , gas density, the length and diameter of the tube, and the
flow rate of the gas through the tube
The product of compliance (C) and resistance (R) is called -✓✓Time constant
Three basic methods have been developed to mimic or replace the normal
mechanisms of breathing -✓✓1. Negative-pressure ventilation
2. Positive pressure ventilation
3. High frequency ventilation
, The pressure difference between the alveolus (Palv) and the body surface (Pbs) is
called -✓✓Transthoracic pressure
Define elastance -✓✓Ability of a structure to return to its natural shape after
stretching
What is the formula used to calculate compliance -✓✓C= ^V/^P ( ^ =change of )
Another term for airway pressure is -✓✓1. Mouth pressure
2. Airway opening pressure
3. Mask pressure
Intraalveolar pressure (in relation to atmospheric pressure) at the end of inspiration
during a normal quiet breath is approx. -✓✓10 cm H2O
What may be associated with and increase in airway resistance? -✓✓Decreasing
the flow rate of gas into the airway
PEEP is best defined as -✓✓Positive pressure at the end of exhalation on a
mechanical ventilator
ventilation -✓✓movement of air into and out of the lungs
respiration -✓✓involves the exchange of oxygen and carbon dioxide between an
organism and its environment
internal respiration -✓✓occurs at the cellular level and involves the movement of
oxygen from the systemic blood into the cells
external respiration -✓✓involves the exchange of oxygen and carbon dioxide
between the alveoli and the pulmonary capillaries
compliance -✓✓can be described as the relative ease with which the structure
distends; inverse of elastance; elastic forces that oppose lung inflation
resistance -✓✓measurement of the frictional forces that must be overcome during
breathing
