Respiratory Flashcards
organ of smell, mucous membranes with rich blood supply
nose
3 bones - increase surface area for filtering, warming and humidifying air
turbinates
passageway for both respiratory and digestive tract. Behind oral and nasal cavities
pharynx
Voice box- contains C shaped cartilage and vocal cords
layrnx
provide resonance to speech, decrease weight of skull and act as shock absorbers
sinuses
lower airway- in front of esophagus. Branches to R/L mainstem bronchi at carina junction. Contains cartilage rings
trachea
Where the trachea joins the mainstem bronchi
Carina
begin at the carina, cartilage tissue
mainstem bronchi
branch from mainstem bronchi. Complete cartilage and resist collapse. Lined with ciliated mucous membrane
lobar, segmental, subsegmental bronchi
smaller and smaller tubes, no cartilage and depend on elastic recoil of lung to remain open
bronchioles
resemble grapes- basic units of gas exchange
alveoli
fatty protein that reduces surfactant tension
surfactant
smooth membrane with 2 surfaces that totally enclose the lungs
pleura
lines the inside of chest cavity and upper surface of diaphragm
parietal
covers lung surfaces - allows the surfaces to glide across each other smoothly during breathing
visceral
thin fluid filled space between visceral and parietal pleura
pleura cavity
What hx is important when assessing a patients respiratory system?
smoking (what kind), hobbies, work enviornment, pack years, allergies, asthma
physical assessment of Resp system
cough, sputum, SOB, chest pain, length of illness
What labs do you use to assess resp system?
O2, RBC, H&H, ABGs
What radiographic tests are done?
Chest X ray, CT
Noninvasive resp assessment tools
pulse ox, PFTS, Skin tests (turgor), PFTS
invasive resp exam
endoscopy, thoracentesis, lung biopsy
needle aspiration of pleural fluid from pleural space for diagnostic purposes
thoracentesis
obtain tissue for histologic anaylsis, culture or diagnosis
lung biopsy
