Respiratory Care Equipment chapter 52017 questions with answers.
Increasing ,lower ANS -By doing what to the surface area a given force can be maintained at a what
pressure
The volume and therefore the surface area ANS -By increasing this of the cuff the pressure required to
seal the tube against the trachea wall is decreased
5 mmHg ANS -Cuff pressures greater than this reduce lymphatic flow
18 mmHg ANS -Cuff pressure is greater than this reduce venous flow
30 mmHg ANS -Arterial blood flow will be reduced when pressures exceed this
20-25 ANS -Cuff ranges should not exceed this...normal maximum range
Resuscitation valve design, valve ANS -Influences the ability of this to respond to a patient's inspiratory
effort, to allow administration of oxygen and Rich gas, as well as the ease of which it becomes
obstructed with secretions or aspirate
Diaphragm or leaf type ANS -The simplest type of resuscitator valve. Made of a flexible rubber or plastic
that will distort when pressure is applied
Diaphragm or leaf type ANS -This type of valve will change shape in response to small pressure changes,
which is advantages just in sensing a patient spontaneous breathing efforts
A diaphragm valve ANS -Opens when pressure proximal to the valve seat distorted. It closes when
pressure distal to the valve seat forces the valve against the seat closing it
, Pouiseuilles Law ANS -Relates the diameter of a tube to the resistance and posed to a gas flowing
through it. Critical and both artificial Airways and suction catheters
Harder the work ANS -The smaller the diameter tube of a artificial Airway the
16 times ANS -As the radius decreases by 1/2 the resistance will increase how many times
400 and 600 ANS -Sub ambient pressure from the supply lines
80 to 100 ANS -Normal range of sub ambient pressure for neonates
Less than 150 mmHg ANS -Normal Subambient pressure for adults
Soft tissue obstruction, central nervous system depression, drug overdose or anaesthesia, Cardiac
Arrest, loss of consciousness, space occupying lesion, edema, or foreign body aspiration what ANS -
Causes of upper Airway obstruction
Soft tissue obstruction ANS -Usually caused by the muscles this relaxing resulting in falling posteriorly
and obstructing the airway
Loss of consciousness for example cerebrovascular accidents or CVS, or sedative or narcotic drugs...also
or central nervous system depression ANS -Causes of loss of muscle tone
To reposition the Airways such that the tongue is moved anteriorly away from the posterior pharynx
ANS -Goal of opening the upper Airway maneuvers
MAE ANS -Management of Airway emergencies
Identification of the causes of Airway emergencies, Management's prior to tracheal intubation, use of
equipment and techniques for keeping ventilation ANS -Mae includes
