QUESTIONS 2026
◉ Respiratory Failure. Answer: Inability to maintain adequate gas
exchange.
◉ Compromised Airway. Answer: Obstruction or inability to
maintain airway patency.
◉ PaO2. Answer: Partial pressure of oxygen in arterial blood.
◉ PaCO2. Answer: Partial pressure of carbon dioxide in arterial
blood.
◉ Persistent Acidosis. Answer: Blood pH below 7.32 indicating
acidosis.
◉ Drug Overdose. Answer: Excessive drug intake leading to
respiratory depression.
◉ Neuromuscular Disorders. Answer: Conditions affecting nerve
and muscle function.
,◉ Inhalation Injury. Answer: Damage to lungs from inhaling harmful
substances.
◉ Polytrauma. Answer: Multiple traumatic injuries affecting
different body parts.
◉ MODS. Answer: Multiple Organ Dysfunction Syndrome, failure of
multiple organs.
◉ Positive Pressure Ventilation. Answer: Air is pushed into the lungs
mechanically.
◉ Negative Pressure Ventilation. Answer: Air is drawn into the lungs
by pressure drop.
◉ Volume Cycling. Answer: Ventilator delivers preset volume before
exhalation.
◉ Pressure Cycling. Answer: Ventilator delivers breath until preset
pressure is met.
◉ Barotrauma. Answer: Lung injury from excessive pressure during
ventilation.
,◉ Non-Invasive Ventilation (NIV). Answer: Ventilation support
without intubation using masks.
◉ Continuous Positive Airway Pressure (CPAP). Answer: Delivers
constant pressure to keep airways open.
◉ Bi-level Positive Airway Pressure (BiPAP). Answer: Uses two
pressures for inhalation and exhalation.
◉ Controlled Mechanical Ventilation (CMV). Answer: Ventilation
mode for fully sedated patients.
◉ Endotracheal Tube (ETT). Answer: Tube inserted into the trachea
for ventilation.
◉ Tracheostomy. Answer: Surgical opening in the trachea for airway
access.
◉ Respiratory Therapist. Answer: Healthcare professional
specializing in respiratory care.
◉ Ventilator Modes. Answer: Different settings for mechanical
ventilation operation.
, ◉ Airway Adjuncts. Answer: Devices assisting in maintaining airway
patency.
◉ Oxygenation Improvement. Answer: Enhancing oxygen delivery to
tissues.
◉ Sedation in Ventilation. Answer: Use of sedatives to facilitate
mechanical ventilation.
◉ Assist Control. Answer: Ventilator mode allowing patient-initiated
breaths with set pressure.
◉ Synchronized Intermittent Mandatory Ventilation (SIMV).
Answer: Ventilator delivers set breaths; patient can breathe
spontaneously.
◉ Pressure Support Ventilation. Answer: Weaning mode providing
pressure support during spontaneous breaths.
◉ PEEP. Answer: Positive end-expiratory pressure to maintain
airway patency.
◉ Vital Capacity. Answer: Maximal air inhaled and exhaled in one
breath.
