Respiratory Exam Flashcards
Two components of a respiratory exam
- Extra pulmonary portion
2. Pulmonary portion
Extrapulmonary examination- areas of examination
1) Detection of cyanosis
2) Clubbing of fingers
3) Trachea
4) Accessory respiratory muscles
5) Lymph nodes
6) Ears
7) Noses
8) Sinuses
9) Mouth/throat
Meaning of cyanosis
-bluish coloured skin
Types of cyanosis
- central
- peripheral
Cause of peripheral cyanosis
- usually normal
- related to constriction of vessels in the extremities (ex due to cold)
Cause of central cyanosis
Low oxygen in blood
Sign of central cyanosis
Lips and face?? really thought the lips were not included -want to look orally
Haemoglobin in blood to see cyanosis
-must be 5gm/dl of deoxygenated haemoglobin present to see cyanosis
Clubbing of fingers -in which patients do see
- chronically hypoxemic patients (but also in patients with normal O2 levels)
- congenital heart disease
- lung cancer
- lung absces
- empyema
- cystic fibrosis
- gi causes (rare)
Recognizing clubbing
Curving of the fingernails
Softening of the nail bed
Loss of angle between the nail and dorsum of the finger
Shifting of trachea with age
May be shifted slightly to the right in older people
Pathological shifting of the trachea
1) Pushed to the opposite side by a large pneumothorax or pleural effusion
2) Drawn towards the side of extensive atelectasis
3) Thyroid enlargement may shift it either way
Examination of trachea
Patients head in mild flexion by the one or two finger method
Compare distance from lateral tracheal wall to the bony medial border of the suprasternal notch
Accessory respiratory muscles-when do see
Normally not seen unless the patient is very short of breath
in a patient with obstructive lung disease -seeing this correlated with FEV1 <30%
Accessory resp muscles -which is the most evident in the dyspnoeic patient
-sternocleidomastoid
Lymph nodes -which to palpitate
1) Occipital
2) Pre and post auricular nodes
3) Sub-mandibular nodes
4) Anterior and posterior cervical nodes
Lymph nodes -what to note
- soft, tender, mobile nodes = associated with infection
- firm/hard “matted down” nodes -signify malignancy
Lymph node in neck most frequently involved wiht lung cancer
Supraclavicular nodes (node may feel like a hard pea)
Ears examination
- examine auricle of ear
- check behind ear for nodes
- check the lobule and helix for infected piercings from earrings
- using ototscope look at auditory canal - note wax and other foreign bodies
- look for redness/swelling of otittis externa
- assess tympanic membrane for perforations, redness and bulging
Nose
1) examine the nose looking for foreign bodies
2) assess health of mucosa (redness, swellling, bleeding/scabbing of Little’s area
3) Assess for deviation of the septum
Sinuses
1) Press up on the frontal sinues from under the bony brows
2) Press up on maxillary sinuses
Mouth/throat
- examine the teeth, gingiva, tongue and pharynx
- note presence/absence of tonsils
4 components of pulmonary exam
1) Inspection
2) Palpation
3) Percussion
4) Auscultation
Inspection
1) observe patient for extrapulmonary signs - cyanosis, dyspnoea, accessory muscles
2) antero-posterior diamter
3) Deformities
4) Thoracic and/or abdominal breathing - is it symmetrical/regular
Where see antero-posterior diameter changes
With severe obstructive lung disease
