Exam 2 Flashcards
Where does the airway begin & end?
Begins at nose, & ends at terminal bronchiole
Upper airway consists of
nose, larynx, pharynx, & epiglottis
Lower airway consists of
trachea, bronchial tree, R & L Bronchi, segmental bronchi & terminal bronchioles
Function of lower airway
conduct air, clear mucus by cilia, & produce pulmonary surfactant
Which is more anterior ? The trachea or the esophagus?
tracheae is anterior to the esophagus (hence back to sleep)
Trachea ends & becomes right & left lungs where?
at the 2nd intercostal space
Where do the lungs begin & end?
Apex of lungs extend above the clavicle
Base of lungs at the 6th rib
Posteriorly, lungs begin at ___
Base of lung at_?
Lungs begin @ T1
Base of lungs at T10
Deep breathing= T12
Right side of lung
Has 3 lobes, separated by Horizontal fissure
What are the other fissures of the lungs called?
Oblique fissure
ends at 6th rib
Right lower lobe
is practically under armpit
On the left anterior lobe we mostly auscultate
upper lobe
ends at 6th rib mid-clavicular, starts under armpit T3
Right thorax
5th rib mid axillary line unites all 3 lobes
Left thorax
Oblique fissure from T3 beginning -6th rib mid clavicular line
Factors that affect respiration
Hunchback of scoliosis
Air trapped in spaces
Copriised respiration
Right middle lobe
is not a part of posterior right lobe
Position
tripod position=can’t breathe–> drop diaphragm to try to expand their lung volume
Activity & exercise
promotes pulmonary exercise & respond better to respiratory distress
Pregnancy
3rd trimester
orthopnea: not able to be comfortable while laying flat
If patient is having a hard time breathing first thing you should do is
put the head of their bed up
Smoking
contributes to lung disease: macrophages in lung destroy the protein that allow the lungs to expand.
> mucus production
Air pollution
Room air is 21% oxygen
Asbestos & coal dust
cause lung disease
Cough is/signals
Cough is most important lung defense
Clears irritating substances in lungs
warning signal
Generation of cough
Histamine released due to irritated substance
Non-described, long standing cough
Something more serious is going on
Warning sign of HF, lung cancer, HTN
Productive cough has what characteristics
Produces sputum: volume, consistency, color & odor
Is shortness of breathe subjective?
Yes, you cannot tell just by looking at them. Explore degree with pt.
Word for subjective SOB
Dyspnea
What are the characteristics of central hypoxia?
confusion, anxiety, inability to follow direction
Signs of respiratory distress?
clubbed nails, tripod position, nasal flaring
breathing pattern characteristics
Rate, rhythm & depth
Signs of effort to breathe
distressed, diaphragmatic, labored, pursed lips
skin color
general color, lip color, nail bed
Hyperpnea
tachypnea but deeper
Hypoventiliation
breathing less than 12 bpm but more shallow
Cheyne-stokes
periods of apnea
Last 10-60 sec flowed by periods of hyperventilation
Common in people in comas or about to die
Pectus Excavatum
Congenital deformity
Hollow chest: internal cartilage & ribs are concave
Applies pressure to heart & lungs
Treatment: invasive surgery
Pectus Carintum
Pigeon chest–> sternum protrudes
Repair is easy
Develops during school age
Spinal Deformities
Hyphotic spine: more difficult to breathe,
< stature
Barrel Chest
Round chest configuration
Sternum pushed out
Common in COPD
1:1 ratio instead of normal anterior thorax is 2x as big as posterior
Normal chest configuration
Anterior/posterior diameter if chest is 1/2 the length of the transverse
Barrel chest
1:1 diameter of the chest
Commonly seen in: emphysema, cystic fibrosis, infants & elderly
Respiratory expansion
Palpation, assessing the symmetry of the chest expanding during inhale & exhale
Thumbs on T10 vertebrae with fingers spread apart, look for thumb movement & symmetry
Where to begin acultation?
on the back
Listen side–> side
Top to bottom
Compare to other side & look for asymmetry
Bronchial sound charactersitics
Over the trachea & larynx, LOUD, inspiration 1/3 of expiration
Bronchiovesicular
Over the sternum, 2-3 intercostal space
T3 & T4
I=
Vesicular sound
Everywhere else
Inspiration 2/3 expiration 1/3
GENTLE
When normal lungs are displaced?
Breathe sounds are diminished in intensity
Adventitious breathe sounds are…
Always abnormal but not always significant
The larger the airway
The louder the sound
Crackles
High pitched and discontinuous
Heard at the end of inspiration
Does not clear with coughing
Sign of buildup of phlegm & fluid in alveoli
Pneumonia crackles
Consolidation of alveoli
Airspace is filled with excaudate & anti-inflammatory modifirs
Crackles & bronchial breath sounds
Pulmonary Edema
Develop crackles due to excess of fluid in alveoli
Becomes more coarse over time
s/s of pulmonary edema
Dyspnea, SOB, lower, lower O2 saturation, air hunger, orthopnea, have productive cough
Wheeze
Heard on inspiration & expiration (usually louder on expiration)= continuous
High pitches/ musical
Asthma is…
What type of adventitious breathe sounds will you hear with it?
Wheeze
Chronic inflammation of the lungs: contact with allergen triggers- narrows airway & lungs swell
Stridor
Strong wheeze, obstructed airway associated with upper larynx & trachea
Croup is associated with ___ breathing
associated with stridor on inspiration, expiration sounds like barking seal
Swelling & inflammation of vocal cords & throat
Rhonchi
snoring, low pitched o
Heard on inspiration & expiration
May clear with coughing
Caused by air bubbling past secretions in large airways
Ronchi is associated with
Bronchitis
Inflammation of bronchi causing an > production of mucus on lining of upper airways
Air passing through mucus membrane causes bubbling rhonchi
Pleural friction rub
Low pitches, dry grating sound
Heard on inspiration & expiration
Pleural friction rub is associated with:
Pleurisy: inflammation of the lining of the lungs
-deeper breaths the more pain they experience
Breathe shallowly and < frequently
-hypotonia- (< muscle tone)
-hyperventilation
Pleural Effusion
Diminished or absent breathe sounds over effected area.
Collection of pleural fluids that is outside the lungs.
Pleural effusion is associated with:
Pneumothorax: Lung has collapsed, air around the lung cannot contract
You will hear normal breathe sounds on one side & none on side that is collapsed
Hemothorax
collection of blood outside the lungs
Chest Physiotherapy
Percussion called clapping! Also can do vibrations= manual compression & tremor on chest wall
Purpose: to loosen & mobilize secretions & cause clearance. Use gravity
People with _____ illnesses have large secretions & don’t have productive cough
pneumonia, cystic fibrosis, COPD
Chest X-ray
can see fluid/air in pleural space
Collapsed or under-inflated lung. Consolidation
Position of catheter tube
Peak flow meter
measure peak EXPIRATION
Reflects size of airways, severity of illness= how constricted
male expires ~600mL/min
Female expires ~475mL/min
Incentive spirometry
Measures maximal inhalation
8-10 breaths/Hr w/a
Male inhales ~3200mL
Females inhale ~2600mL
Prevents pneumonia & collapsed lung
Get secretions in lungs at level to be coughed out
aerosol therapy:
small volume nebulizers:
Add moisture to O2 delivered
Hydrates thick sputum (delivered to deep area of respiratory tract)
side effects of bronchodilators
> HR, BP, RR, agitation, anxiety, fluid retention
Aerosol therapy: steroids
Pt uses 4/5 L of O2
Inhale slowly, or hold breathe, exhale through nose, inhale
Keep in mouth until all medication is gone
Mouth care after they finish
Assess pt before & after pt uses med
Sputum culture
lab test (30 min) or C&S both tell you which antibiotics to order
after surgery there’s a risk for
lung collapse since cough reflex was suppressed, after surgery= pt in pain, alveoli not inflating secretions being retained
Types of cough
Deep cough: no pain, take a deep breathe & forceful expiration
Stacked cough: in pain
Series of short, quick coughs
Take in deep breathe in but force out is quick
Pursed lip breathing
Pt is having a difficult time breathing, keeps bronchial expanding
breathe through nose (for count of 2)
Exhale through the lips (for count of 4)
