Respiratory Structures include:
mouth, nose, pharynx, trachea, lobar bronchi, segmental bronchi, bronchioles, alveoli,
lungs
Respiratory System Function
replenishes the body's oxygen supply and eliminates waste from the blood in the form of
carbon dioxide
ventilation
physical process of moving air into and out of the lungs for gas exchange
Gas Diffussion
process in which molecules move from an area of greater concentration to an area of
lower concentration
What are the defenses of the respiratory system
structures filter inspired air, warm, humidify, and destroy bacteria
Characterize normal breathing
smooth, even, and regular
Normal RR of adult male under 60 yrs
12-20
Normal RR of adult male 60 yrs and older
16-25
, What factors affect respiratory function
body position, environment (allergens/pollution), lifestyle (drugs/nutrition/smoking),
restricted lung movement and airway obstruction
restricted lung movement
requires more work for lung expansion, thus respiratory muscles consume an increased
amount of oxygen
airway obstruction
reduced diameter of conducting airways causes increased airway resistance &
increases the work to move air through
What are altered Respiratory Function
cough, sputum production, shortness of breath and chest pain
Levels of Dyspnea
Older adult considerations: Respiratory system
thoracic wall becomes more rigid
protective functions of lungs are impaired
normal PaO2 decreases with decreased response to hypercapnia
What are the four major areas of respiratory hx assessment
risk factors, s/s, impact of respiratory status on ADL, and adaptive measures taken
Bradypnea definition and causes
respiratory rate below 12 breaths/min
