Paramedic FISDAP Airway Exam
2026- Well Revised Exam With
Verified Solutions
Visceral pleura - correct-answer -Thin, slippery, outer membrane covering the
lungs.
Parietal Pluera - correct-answer -Lines the inside of the thoracic cavity.
Bronchioles - correct-answer -Made of smooth muscle & lined with beta-2
receptors, which can dilate and constrict based on stimuli.
Alveoli - correct-answer -Balloon-like clusters of single-layer air sacs, and serve as
the functional site for the exchange of oxygen and CO2. This exchange occurs by
simple diffusion over the pulmonary capillaries.
, 2
Ventilation - correct-answer -Process of moving air in and out of the lungs. Consist
of two phases- inhalation and exhalation.
Oxygenation - correct-answer -Process of loading O2 molecules onto hemoglobin
molecules in the bloodstream.
Respiration - correct-answer -Actual exchange of O2 and CO2 in the alveoli and
the tissues of the body.
Inhalation - correct-answer -Air enters the body, the diaphragm and intercostal
muscles contract. When the diaphragm contracts, it descends and enlarges the
thoracic cage from top to bottom. When the intercostal muscles contract, they lift
the ribs up and out.
Diaphragm - correct-answer -Stimulated by the Phrenic Nerve, it is a voluntary
and involuntary muscle.
Accessory Muscles - correct-answer -Secondary muscles of breathing, and include
the sternocleidomastoid and trapezius muscles of the neck.
, 3
Negative Pressure Ventilation - correct-answer -The air outside the body, is
normally higher in pressure than the air within the thorax. During inhalation, the
thoracic cage expands and the air within the thorax decreases, creating a slight
vacuum. The vacuum pulls the air in through the trachea, causing the lungs to fill.
Positive Pressure Ventilation - correct-answer -With ineffective chest movement,
or no chest movement, negative intrathoracic pressure cannot be created. When
this occurs, the only way to move air into the lungs is by PPV, the forcing of air into
the lungs.
Tidal Vol/Dead Space/Residual Vol/Total Lung Capacity - correct-answer -Tidal-
500ml
Total Lung Capacity- 6,000ml/5-6L
Dead Space- 150ml
Residual Vol- 1,200ml
Hering- Breuer Reflex - correct-answer -Terminates inhalation to prevent over-
expansion of the lungs.
Medulla - correct-answer -Primary involuntary (autonomic) respiratory center.
Connected to the respiratory muscles by the vagus nerve. The medullary
respiratory center controls the rate, depth, and rhythm of breathing.
