CardioRespiratory Flashcards
What are the physical examinations?
inspection, palpation, percussion, auscultation
What 5 things should you inspect?
vital signs, mechanism of ventilation, thoracic shape, head/neck/extremities, speech/cough/sputum
What are the 4 vital signs?
HR, RR, BP, SPO2
How to take HR, and what to note
radial artery with index and middle finger. Ask patient to be quiet and count for 15 secs and multiply by 4. Note rate, rhythm, and strength of pulse
Different HR?
bradycardia: <60bpm, normal: 60-100bpm, tachycardia: >100bpm
Rhythms
normal: regular consistent pattern, irregular: irregular but consistent pattern (bigeminy, trigemini), irregularly irregular: irregular but inconsistent pattern (atrial fibrillation)
How to measure RR and the wording for too high, normal, and too low?
Do it without the patient knowing. Bradypnea (less than 12), eupnea (12-20), tachypnea (greater than 20)
Normal RR for an adult?
12-20
normal RR for adolescent?
16-20
normal RR for child
20-30
normal RR for toddler (2yr)
25-32
normal RR for infant (6month)
30-40
normal newborn RR
35-40
How to take blood pressure?
upright seated, left arm supported at heart level, palpate brachial artery and place cuff 1 inch above that. stethoscope under cuff and on pulse and ask patient to be quiet. inflate until pulse is gone then add an extra 20 mmHg, Deflate slowly. Systolic BP is first noise, diastolic is when gone.
BP values
hypotension : <90/60.
normal: 120/80
hypertension: >140/90
orthostatic hypotension (SBP drops by 20 from lying to upright)
Considerations for taking BP measurements
Ensure cuff size is approx 80% of arm
too large= underestimate BP
too small= overestimate BP
Locations for SPO2 reading
finger or ear lobe
Normal value for SPO2 and when to require supplemental O2
Normal is 95-100%, below 90% warrants further investigation.
What is the normal breathing pattern? Percentage diaphragmatic vs costal?
> 70% diaphragmatic and <30% costal. 0% shoulders
What are signs of distress or increased metabolic demand?
apical, paradoxical, flail chest, use of abs to actively expire
Ratio of inspiration: expiration in normal, obstructive and restrictive diseases
normal- 1:2
obstructive- 1:3(or more)
restrictive- 1:1
What are the threee areas of mechanisms of ventilation to be aware of?
breathing pattern, ratio of inspiration:expiration, and depth (normal v shallow)
What are 4 abnomral thoracic shapes that can affect mechanics of ventilation and V/Q matching?
funnel chest (pectus excavatum), pigeon chest (pectus carinatum), kyphoscoliosis, barrel chest (AP:lateral = 1:1)
What to look for in the head? (3)
colour, cyanosis, nasal flaring
What to look for in the neck? (2)
accessory muscle use, jugular venous distension
What to look for in the extremities? (5)
capillary refill, clubbing, colour, edema, muscle wasting
What is a clubbing sign in fingers?
Schamroth’s Sign. put index fingers together and if there is a gapping (or no diamond window) then clubbing is present. A clubbed finger has a >180 degree bend.
4 things to analyze with coughs?

What are 6 things to palpate for during respiratory examination?
chest wall expansion, diaphragmatic excursion, edema, pain and crepitus, tracheal positioning, tactile fremitus
What are the two methods for assessing chest wall expansion?
manual method or circumferential method
what is the manual method for assessing chest wall expansion?
hands on and assessing for symmetry and amount of movements in 3 areas (upper lobes @ sterno-costal, middle lobes/ lingual @ verebro-costal, and lower lobes @lateral costal)
What is the circumferential method for assessing chest wall expansion?
using a measuring tape and comparing full inspiration vs full exhalation. Measure @ axilla or 10th rib. Take 3 measurements and record best 3.
What are the 3 methods for assessing diaphragmatic excursion?
Manual method, circumferential method, and diaphragmatic percussions
what is the manual method for assessing diaphragmatic excursion?
hand placed on the apex of belly during inspiration
what is the circumferential method for assessing diaphragmatic excursion?
place tape at level of apex of belly and instruct patient to first exhale and then maximally inhale
What are two things to assess with edema?
Pitting vs non-pitting and the level (how far up does it extend)
What are 4 possible conditions that may cause respiratory edema?
right-sided heart failure, pregnancy, lymphedema, systemic diseases
What would pain indicate when doing a respiratory examination?
palpation producing pain could aid in differentiating between angina due to an organic nature or musculoskeletal pain.
What is crepitus in the respiratory area and what does it indicate?
it is when air bubbles are trapped in the subcutaneous tissue and a crackling sensation can be palpated (known as subcutaneous emphysema).
Possibly caused by air leak from chest tube, trauma, pneumothorax
Where should the trachea be located?
between the sterno-costal joints
What would increase and decrease in lung volume or pressure do to tracheal positioning respectively?
increase volume/ pressure pushes mediastinum away (pneumothorax, pleural effusion, tumor/mass). Decrease volume/pressure shofts mediastinum ipsilateral (atelectasis, pleural fibrosis, pneumonectomy)
What is the mediastinum?
The mediastinum is an area found in the midline of the thoracic cavity , that is surrounded by the left and right pleural sacs. It is divided into the superior and inferior mediastinum, of which the latter is larger.
What is tactile fremitus? How do you perform it?
palpable vibration of the chest wall that results from the transmission of sound vibrations through the lung tissue to the chest wall. Therapists uses palm of hand to feel for vibrations from sound transmitted when a patient repeats loudly “99”
What does an increase in sound transmission mean when performing tactile fremitus?
more dense tissue (ie. pneumonia)
What does a decrease in sound transmission mean when performing tactile fremitus?
less dense tissue (ie. pleural effusion, pneumothorax)
What are the two types of percussion you can do?
diagnostic percussion and diaphragmatic percussion
what is the purpose diagnostic percussion?
to determine the density if the underlying tissue. Can detect abnormalities up to 5 cm in depth.
What tissues will alter ability to perform diagnostic?
SUBCUTANEOUS FAT
how do you perform diagnostic percussion?
place the finger of a hand with an extended DIP directly on the chest wall with firm pressure
Strike the DIP of the hand placed on the chest wall with the tip of the middle finger of the other
hand
Motion comes with quick snap of the wrist
Perform 2-3 strikes
Best performed on exposed skin (use proper draping)
What are the 3 percussion sounds you could hear?
resonant, dull, hyperresonant (tympanic)
What does resonant percussion sound mean?
normal aerated lung tissue (air:tissue ratio normal) over normal lung tissue
What does a dull percussion sound mean?
non-aerated lung tissue (air:tissue ratio below normal). could be atelectasis, pneumonia, over organs, tumor.
What does hyperresonant (tympanic) percussion sound mean?
hyperinflated lung (air:tissue ratio above normal) (COPD, pneumothorax, over empty stomach)
How do you perform diaphragmatic excursion?
Performed with patient in sitting
Ensure patient knows how to use diaphragm (if not, educate)
Patient is asked to maximallyexhale and hold as therapist percusses down the same
side of the chest wall (posteriorly) Therapist makes a marking when a dull sound is
heard (diaphragm)
Patient is asked to maximally inhale and hold as therapist percusses down one side of
the chest wall (posteriorly) from the point of the last marking. Therapist makes a
marking when a dull sound is heard (diaphragm)
Normal-3-5cm difference. D E with hyperinflation +other conditions
Note: Diaphragm sits higher on Right than Left
what are the normal breathing sounds?
vesicular, bronchial, bronchovesicular.
what are the abnormal breath sounds?
crackles, wheezes, pleural friction rub, stridor?
What is a vesicular breath sound?
Soft and low-pitched
Heard over peripheral lungtissue (i.e. entire lung except for anterior
and posterior areas over trachea and main stem bronchi) Indicates normal lung.
I:E = 3:1
What is a bronchovesicular breath sound?
Mixture of bronchial and vesicular :E = 1:1
Inspiration is soft, low-pitched Exhalation is loud, high-pitched
What is a bronchial breath sound?
Loud, high-pitched, hollow quallty Louder on exhalation
I:E = 1:1 or 1:2
Distinct pause between I and E Heard over trachea and manubrium
What is a crackles (rales) breath sound?
short, explosive
What are the classifications of crackles?
timing: inspiratory vs expiratory
quality: coarse vs. fine
coarse: usually sputum/secretions
fine: usually fluid (ie. pulmonary edema), also heard in atelectasis and fibrosis.
what is a wheeze (rhonchi) breath sound?
musical, can be affected by coughing.
What are the classifications of wheezes?
pitch: high vs low
timing: inspiratory vs. expiratory
duration: short or long
notes: monophasic vs polyphonic
What is a pleural friction rub (extrapulmonary sound)?
Long, low-pitched, leathery creaking sound
Produced by frictional resistance between layers
Pain may be associated with a pleural friction rub.
May be confused with pericardial rub from heart. To differentiate ask patient to hold their
breath. If rub sound persists then it is a pericardial rub. If rub sound disappears, it is a pleural friction rub.
What is a stridor breathe sound?
Loud, musical, high-constant pitch
Audible from a distance without stethoscope
Most prominent during inspiration
Due to turbulent air flow (upper airway obstruction or narrowed airways)
What are the 3 voice sounds techniques?
egophony, whispered pectoriloquy, bronchophony
How do you perform egophony voice sounds test?
ask the patient to repeat “E” as you auscultate, if you hear “A” it is an indication of consolidation (mucous or lung tissue)
How do you perform whispered pectoriloquy voice sounds test?
whispered words change from muffled over normal lung tissue to clear(er) over areas of consolidation
How do you perform bronchophony voice sounds test?
increased intensity and clarity of vocal resonance indicated consolidation
What are the 4 categories of pulmonary function tests?
volume, capacity, flow, diffusion studies, respiratory muscle strength
What is tidal volume?
the volume of air inhaled or exhaled during a single breath in a resting state (normal quiet breathing)
What is inspiratory reserve volume (IRV)?
the max amount of air inhaled following a normal inspiration
What is expiratory reserve volume (ERV)?
the max amount of air that can exhaled after a normal exhalation
what is the residual volume?
the volume of air remaining in the lungs at the end of maximum expiration (can’t exhale it)
What does a decreased tidal volume indicate?
restrictive disease, lung cancer, atelectasis, msk impariment
What does increase residual volume indicate?
obstructive disease
what does decreased residual volume indicate?
restrictive disease, lung cancer, atelectasis, msk impairment
what does increased inspiratory reserve volume indicate?
obstructive disease
what does decreased inspiratory reserve volume indicate?
restrictive disease
what does decreased expiratory reserve volume indicate?
pleural effusion, pneumothorax, ascities
