John Hutchinson
René Laennec
Björn Ibsen
Mechanical engineer John Emerson refined Drinker and Shaw's iron lung in the 1930s, making it lighter and more affordable. His improvements allowed broader hospital adoption of negative pressure ventilation.
Which innovation in 1971 significantly transformed neonatal respiratory care?
Adult mechanical ventilator use
Continuous positive airway pressure (CPAP) for infants
Heliox therapy for neonates
Iron lung adaptation for neonates
In 1971, Dr. Gregory introduced neonatal CPAP, applying continuous airway pressure to premature infants. This approach decreased lung injury and improved survival in neonatal respiratory distress syndrome.
What is the primary purpose of applying positive end-expiratory pressure (PEEP) in mechanical ventilation?
To measure airway resistance
To increase inspiratory volume only
To deliver aerosolized medications
To prevent alveolar collapse at end expiration
PEEP maintains pressure in the lungs at the end of expiration, keeping alveoli open and improving oxygenation. This prevents atelectasis and enhances gas exchange in mechanically ventilated patients.

Negative pressure ventilation chamber
Forrest Bird's Mark 7 ventilator was among the first lightweight, portable positive pressure ventilators. Its design allowed greater mobility and flexibility in patient care outside of large negative pressure chambers.
Who pioneered the use of CPAP to treat obstructive sleep apnea in 1981?
Robert Drinker
Colin Sullivan
John Emerson
Björn Ibsen
Australian researcher Colin Sullivan introduced nasal CPAP for obstructive sleep apnea in 1981. This noninvasive technique revolutionized sleep medicine by stabilizing the airway during sleep.
Which gas mixture, first used in the early 20th century, reduces airway resistance and work of breathing?
Nitrous oxide
Sulfur hexafluoride
Heliox
Carbogen
Heliox, a blend of helium and oxygen, has a lower density than air and improves laminar flow in constricted airways. It was adopted to ease breathing in conditions like asthma and upper airway obstruction.
In what year was the first metered-dose inhaler (MDI) introduced?
1956
1971
1846
1928
The first MDI, launched in 1956, allowed precise dosing of aerosolized medication using a portable, pressurized canister. This innovation greatly enhanced outpatient asthma management.
Which ventilation mode, introduced in the 1970s, cycles mandatory breaths at set intervals regardless of patient effort?
Intermittent mandatory ventilation (IMV)
Pressure support ventilation
Bi-level positive airway pressure
Continuous mandatory ventilation (CMV)
IMV delivers a preset number of mandatory breaths at fixed intervals, independent of spontaneous breathing efforts. It allowed partial respiratory support and facilitated weaning protocols.
What device uses the Venturi principle to deliver a fixed concentration of oxygen?
Face tent
Oxygen tent
Nasal cannula
Venturi mask
The Venturi mask entrains room air through a jet nozzle at a calculated rate, delivering precise FiO2 levels. It became essential for controlled oxygen therapy in respiratory care.
During the 1952 Copenhagen polio epidemic, which practice change reduced ventilator mortality from around 90% to 15%?
Positive pressure ventilation via tracheostomy
Early administration of heliox
Exclusive use of iron lungs
Introduction of CPAP
Björn Ibsen's implementation of positive pressure ventilation through tracheostomy stations revolutionized polio care, drastically lowering mortality. This approach replaced the reliance on negative pressure ventilators.
Which modern ventilation mode synchronizes support with the patient's diaphragm electrical activity?
Synchronized intermittent mandatory ventilation
Pressure-controlled ventilation
High-frequency oscillatory ventilation
Neurally adjusted ventilatory assist (NAVA)
NAVA uses electrodes to detect diaphragmatic electrical signals, coordinating ventilator breaths with patient effort. This innovation enhances patient - ventilator synchrony and comfort.
Which inhaled therapy, introduced in the 1990s, became a standard treatment for neonatal pulmonary hypertension?
Heliox therapy
Continuous positive airway pressure
Inhaled nitric oxide
Intravenous prostacyclin
Inhaled nitric oxide, approved in the early 1990s, selectively dilates pulmonary vessels without systemic effects. It significantly improved outcomes in neonates with persistent pulmonary hypertension.
How does high-frequency oscillatory ventilation (HFOV) primarily differ from conventional ventilation?
Provides only continuous airway pressure
Alternates between inhaled and exhaled heliox
Uses very high rates and very small tidal volumes
Delivers large tidal volumes at low rates
HFOV operates at frequencies up to several hundred breaths per minute with tidal volumes below anatomical dead space. This minimizes lung injury while ensuring adequate gas exchange.
Why are microprocessor-controlled ventilators significant in modern respiratory care?
They eliminate the need for clinician oversight
They use only negative pressure techniques
They are heavier and more durable
They allow precise control of complex ventilation modes and real-time monitoring
Microprocessors enable sophisticated algorithms that adjust ventilation parameters, deliver advanced modes, and provide continuous data feedback. This technology has improved safety, customization, and patient outcomes.
