Respiratory Emergencies - Norkus Flashcards
Number of lobes on right
4: cranial, caudal, middle, accessory
Number of lobes in left lung?
2: cranial and caudal
What makes up anatomical deadspace
Bronchus, terminal bronchioles
V(D)
Still included in tidal volume
What makes up respiratory zone?
Respiratory bronchioles and alveolar ducts
What is the pleural space?
Space between the lungs and the thoracic cavity; normally at -5cmH2O
What happens during inspiration?
The diaphragm flattens, and what the help of the external intercostal muscles. The pressure within the plural space becomes more negative (-10cmH2O) and air is sucked into the alveoli
Tidal volume
The volume of gas normally inspired within one
10–20mL/kg
Functional residual capacity (FRC)
The volume of error that remains within the lung after a normal expiration
This prevents the lung from fully collapsing
Residual volume
The remainder of the air if an individual expired as much as they absolutely could
Vital capacity
The maximum volume of air a patient can consciously control
Total lung capacity (TLC)
The sum of vital capacity, title volume functional residual capacity and residual volume
Minute volume
V(E)
Total ventilation
V(T) x V(f)
Tidal volume x the rate of breathing
Alveolar ventilation
The proportion of inspired gas that actually enters the respiratory zone
V(A)
Medullary respiratory center
Essential for generation of respiratory rhythm located in the brainstem
Cells within the dorsal respiratory group are responsible for what action
Inspiration
