Structural Changes
What happens to the elasticity of lung tissue with aging?
Lung tissue loses elasticity, making it harder to expand and contract.
How does aging impact vital capacity?
Vital capacity decreases, reducing the amount of air exhaled after a deep breath.
How does aging affect the immune response in the lungs?
The immune response weakens, increasing susceptibility to infections.
How does aging affect respiratory muscles?
Respiratory muscles weaken, reducing breathing efficiency.
What lifestyle change can improve respiratory health in aging individuals?
Regular aerobic exercise to maintain lung capacity.
How does aging affect the shape of the ribcage?
The ribcage becomes stiffer and less flexible, reducing lung expansion.
What is the effect of immobility on tidal volume?
Tidal volume decreases, leading to shallow breathing.
What role does immobility play in respiratory infections?
Immobility promotes mucus pooling, creating an environment for infections.
What is the impact of immobility on intercostal muscles?
Immobility leads to muscle atrophy, impairing ribcage movement.
How can immobility-related respiratory issues be prevented?
Encouraging mobility and using incentive spirometers.
What structural change occurs in the alveoli due to aging?
Alveoli lose their shape and become baggy, reducing gas exchange efficiency.
How does aging affect the respiratory rate during exercise?
The respiratory rate increases more rapidly due to reduced lung efficiency.
Why are older adults more prone to pneumonia?
Reduced lung function and weaker immune defenses make them more vulnerable.
How does diaphragm function change with aging?
The diaphragm becomes less effective due to muscle weakening.
What dietary habit supports respiratory health in older adults?
Consuming antioxidant-rich foods to reduce inflammation.
How does immobility affect the diaphragm?
Immobility weakens the diaphragm, impairing its ability to assist in breathing.
What is hypostatic pneumonia, and how is it related to immobility?
It is a lung infection caused by pooled secretions in immobile individuals.
How does immobility affect coughing ability?
It weakens the cough reflex, making it harder to clear mucus and debris.
What is the effect of immobility on respiratory muscle endurance?
Endurance decreases, making sustained breathing efforts difficult.
How does smoking cessation benefit aging lungs?
It slows the decline in lung function and reduces disease risk.
What happens to airway support tissues during aging?
They weaken, causing airways to close more easily.
How does aging affect oxygen and carbon dioxide exchange?
The exchange becomes less efficient due to reduced alveolar surface area.
What vaccines are recommended for older adults to protect respiratory health?
Influenza and pneumococcal vaccines.
How can respiratory muscle strength be maintained in older adults?
Through regular physical activity and breathing exercises.
What is the role of physical therapy in managing immobility-related respiratory issues?
It helps improve muscle strength and breathing efficiency.
