Jarvis Chapter 18 Lungs & Thorax Flashcards
Smooth muscle, warms and humidifies, connects larynx to the brochi.
Trachea
goblet cells secrete mucus which traps particles, cilia propels particles out to be swallowed or expelled.
Bronchi/Terminole Bronchioles
What parts of the lower airway transport air but do not exchange gas.
Trachea and Bronchi/Terminole Bronchioles
May indicate pulmonary edema or pneumonia; fine rattling sounds like a carbonated beverage on inhalation and sometimes on exhalation; liquid is in the alveoli & bronchioles; gets louder with coughing; does not clear with coughing
crackles
Functional respiratory unit
Acinus
Rattles, coarse, rattling sounds on EXHALATION, indicates mucus in bronchii, may clear with coughing;
ronchii
Barrel chest, flattening of sternal angle
Signs of COPD
What position is helpful to a client in respiratory distress?
semi-fowlers position helps them breathe; Lean - lean back, feet out, amrs dangling slows the O2 consumption; tripod position allows upper body to work at moving the air
This portion of the airway is not sterile.
Upper Airway
Name the three lung sounds
vesicular, bronchial, bronchovesicular
This portion of the upper airway warms, humidifies, and filters air.
Nose
Major breath sound over most of the lung; soft, low pitch; inspiration is longer than expiration;
Vesicular lung sounds
Maintains inner air pressure, controls infection (traps particles)
Pharynx
Intermediate intensity and pitch; inspiration and expiration are equal in length; best herad at 1st and 2nd ICS (anterior) or between the scapula (posterior) when heard at other locations; consolidation is likely;
bronchovesicular lung sounds
Incomplete rings, vocal cords (sound and voice), initiates cough reflex.
Larynx
Heard over trachea; expiratory sound predominates; is higher pitched and louder; if heard in other locations it indicates consolidation – a space that usually contains air now has fluid
bronchial lung sounds
Opening between the vocal cords.
Glottis
What are the respiratory centers in the brain?
The brain stem: pons and medulla
High CO2
hypercapnia
The only complete rigid ring of cartilage.
Cricoid Cartilage
Low O2
hypoxemia
Slow, shallow breathing causes carbon dioxide to build up in the blood.
Hypoventilation
Which muscles are used in inspiration
The diaphragm is assisted by the intercostal muscles to lift the sternum and elevate the ribs
Rapid, deep breathing causes CO2 to be blown off.
Hyperventilation
Are inhalation and exhalation active or passive?
inhalation - active; exhalation - passive
High surface area for gas exchange.
Acinus
This lung is responsible for 55% of activity and contains three lobes.
Right
postnatal exposure to ETS results in what?
increased incidence of otitis media, resp tract infections, & childhood asthma; possibly related are SIDS, negative behavioral and cognitive issues and increased rates of teen smoking
This lung is responsible for 45% of activity and contains two lobes.
Left
This portion of the pleura lines the outside of the lungs.
Visceral
What changes occur in the thorax and lungs for the aging adult?
costal cartilages calcify; elasticity of lungs decreases; vital capacity decreases; increased residual volume; increased risk for dyspnea;
This portion of the pleura lines the chest wall.
Parietal
Why are elderly at an increased risk of atelactasis and infection, esp post surgical?
reduced ability to cough, loss of protective airway reflexes and increased secretions;
Contains a thin layer of fluid, allows lungs to expand without friction, pressure is -4cm H2O.
Pleural Space
Where ribs join cartilages; not palpable
costochondral junctions
The diaphragm, external intercostals and accessory neck muscles are all considered what kind of muscles.
Inspiratory
The abdominals and internal intercostals are considered what kind of muscles.
Expiratory
In what groups is TB more common?
A disproportionate amount in blacks; and highest in immigrants from Mexico, Phillipines, Vietnam, India, China
Innervated by C3-C5 and phrenic nerve. It increases superior/inferior diameter of chest and elevates lower ribs.
Diaphragm
coarse, crackling sensation palpable over the skin surface; subcutaneous emphysema due to open thoracic injury or surgery
crepitus
Innervated by T1-T11. Increase anteroposterior diameter by elevating ribs.
External Intercostals
predominates in normal healthy tissue
resonance
After heavy exercise or occurring with respiratory distress, commands the use of the scalene, sternocleidomastoid and trapezii to heave up the sternum and rib cage for forced inspiration.
Accessory neck muscles
too much air is present, i.e. emphysema or pneumothorax
hyperresonance
Normally this type of breathing is passive and muscles not needed.
Expiration
pneumonia, pleural effusion, atelactasis, tumor
dull note
These muscles force abdominal contents up to elevated the diaphragm. Used in forced expiration.
Abdominal
What are the four major functions of the respiratory system?
1-supplying O2 to the body for energy production 2-remove CO2, the waste product from energy reactions 3-maintain homeostasis (acid-base balance) of arterial blood 4-maintain heat exchange
These costal muscles draw ribs and sternum downward to decrease anteroposture diameter.
Internal
How long is the trachea (in cm)?
10-11 cm
This color of sputum usually indicates colds, bronchitis, viral infection.
White or clear
The postoperative older adult is at greater risk for these 4 pulmonary complications:
atelectasis, decreased ability to cough, loss of protective airway reflexes, and increased secretions.
This color of sputum usually indicates a bacterial infection.
Yellow or green
Anatomical landmark that marks the site of tracheal bifurcation.
Angle of Louis
This color of sputum usually indicates TB or pneumococcal pneumonia.
Rust
Term for blood in sputum
hemoptysis
This color sputum usually indicates pulmonary edema.
Pink and frothy
The normal stimulus to breathe is (hypercapnia or hypoxemia)?
hypercapnia
Rapid, shallow breathing >24/min.
Tachypnea
The posterior chest contains almost all (upper or lower) lobe.
lower
Increased rate and depth of of breathing. Usually causes dizziness. CO2 loss.
Hyperventilation
To meet increased O2 demands, pregnant women respond normally by increased RR or increased tidal volume (deeper breathing)?
tidal volume
Slow breathing <10/min and regular rate.
Bradypnea
The anterior chest contains mostly (upper, middle, or lower) lobe.
upper and middle
Difficult, labored breathing. SOB.

High pitched, musical, squeaking adventitious lung sound. Occurs with airway obstruction and on expiration.
Wheezing
The _____ chest contains mostly upper and middle lobe with very little lower lobe.
