FISDAP AIRWAY CERTIFICATION
EVALUATION 2026 COMPLETE QUESTIONS
AND ACCURATE ANSWERS
◉ Positive Pressure Ventilation
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
Answer: Tidal- 500ml
Total Lung Capacity- 6,000ml/5-6L
Dead Space- 150ml
Residual Vol- 1,200ml
◉ Hering- Breuer Reflex
Answer: Terminates inhalation to prevent over-expansion of the
lungs.
◉ Medulla
,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.
◉ Chemoreceptors
Answer: Receptors that monitor the chemical composition (pH,
CO2,) of body fluids that are located throughout the body. They
measure the amount of CO2 in arterial blood and pH in CSF, and if
sensed any changes will send signals to the respiratory center.
◉ Dorsal Respiratory Group
Answer: Responsible for initiating inspiration based on the
information received in the chemoreceptors.
◉ Ventral Respiratory Group
Answer: Responsible for motor control of the inspiratory and
expiratory muscles.
◉ Hypoxic Drive
Answer: Pt's with COPD have a hard time eliminating CO2, therefore
always have higher levels of it. The respiratory centers gradually
accommodate elevated CO2 levels. The body uses a backup system,
that stimulates breathing when the arterial O2 level falls, but then
nerves and receptors are easily satisfied with minimal O2.
, ◉ Aerobic Metabolism
Answer: In the presence of oxygen, the cells convert glucose into
energy through this process.
◉ Anaerobic Metabolism
Answer: Without adequate O2, the cells do not completely convert
glucose into energy and lactic acid and other toxins accumulate into
the cell. If this is not corrected (with adequate perfusion and
ventilation) the cells will die.
◉ Hypoxia
Answer: Dangerous condition in which the cells in the tissues do not
receive enough O2.
◉ V/Q Mismatch
Answer: Ventilation and perfusion must be matched. A failure to
match ventilation and perfusion, lies behind most abnormalities in
oxygen and carbon dioxide exchange.
◉ Hypoventilation
Answer: Minute vol- decreases. CO2 elimination- decreases, leading
to hypercarbia. The level of CO2 in the pt's blood will exceed normal
limits.
