Respiratory assessment Flashcards
Which lobe of lung is difficult to assess in auscultation?
Right middle lobe
Access under right arm - especially in women with breat tissue
What would you involve in an initial respiratory assessment and history taking?
- On approach - ABC
- Vital signs
- History (lung disease, smoking, family history, exposure to allergens eg. dust, asbestos and mold)
- OLDCART
- Shortness of breath (how many pillows they sleep with, far can they walk?)
- Sounds - coughs and wheezes
- Sputum (colour and amount)
- Haemoptysis
- Chest pain
What would you do in the physical assessment and inspection? B, C of A-E assessment
Shortness of breath
Assessor muscles (pursed lip breathing, tripod position, unable to lie flat, unable to speak in whole sentences)
Sputum - colour, haemoptysis, frothy blood
Colour - cyanosis - pallor
Breath sounds - adventitious, cough, wheezing or stridor
General demeanour (AVPU, GCS, confused, anxiety, pain)
What would be involved in a physical assessment of respiratory assessment?
- Chest movement – depth, symmetry (unequal expansion)
- Effort – use of accessory, pursed lips, nasal fairing – rate an rhythm
- Oxygen saturation (88-92% normal for COPD)
What is normal respiration like?
- Rate – 12-18
- Rhythm – normal and regular
- Depth
- Oxygen sats (95 and above)
What are you looking for in an inspection of the chest?
- Back and spine
- Scars/lesions
- Shape abnormalities
- Ratio normally 2:1 - chest twice as wide as deep but can reduce in long term respiratory disease)
- Eg.
- Barrel chest )(chronic respiratory disease)
- Funnel chest (sunken sternum)
- Pigeon chest (protrusion of sternum)
Costal angle – normal less than 90 degrees
What are you inspecting in the hands of a respiratory assessment?
Peripheral cyanosis
Cigerette stains
Clubbing
Fine and flapping tremors
What are you inspecting in the mouth and tongue of a respiratory assessment?
- Mucosal cynosis – central seen in lips and tongue
- Hydration – dry and cracked lips and tongue can indicate dehydration
What are you inspecting in the eyes of a respiratory assessment?
- Conjunctiva pallor (possible anaemia) – pull eye lids down should be pink eye lids – if white then not enough oxygen
What would a person be looking for whilst doing chest palpations?
- Ensure no spinal injuries or problems before start
- Palpate firmly down chest noting any 1
1. Tenderness
2. Skin temperature
3. Moisture (sweaty or clammy)
4. Lumps/lesions
5. Surgical emphysema – air trapped subcutaneous tissues under skin
6. Causing difficulty breathing due to swelling feeling crackly under skin as air moves
7. Symmetry of chest expansion (butterflying as place hands on patient shoulders and ask to take a big breath, hands should move symmetrically (both thumbs points together the thumbs should move apart and back together symmetrically) – could be due to trauma, neurological, muscular.
How would a person auscultation the posterior chest?
- Ask patient to put arms across chest and breath normal through – this turns scapular out of the way - mouth (not deeply as can cause hyperventilation)
- Tell to indicate if dizzy
- Use diaphragm then start at apices and work dow bases from side to sign in J shape
- Listen to at least 1 complete breath sound on each section
How would you auscultate the anterior chest?
ON women can’t hear through breast tissue
1. Listen 1 complete breath cycle from top at collar bone
2. Work down midclavicular line
3. Use bell to listen above the clavicale
4. Use diaphragm for rest of chest down to 6th ribs space
5. On right side listen specially to mid axillary line to examine right middle lobe
What is a normal auscultation sounds?
oft low sound like wind in the trees
What are abnormal sounds to hear during auscultation?
wheeze, crackles (COPD, infection oedema), deceased or absent breath sounds (emphysema or obstructed airway)
How would you perform percussion of the chest?
apping
Can’t do over breast tissue
1. Flat hand with fingers apart
2. Then tap middle finger on a knuckle of other hand
3. Patient put arms across chest
4. Start at apices and percuss down back side to side comparing right and left
5. Avoid over scapular and spine (don’t want to be hitting bones)
6. Locate diaphragm and lung bases by noting dullness
What is the normal percussion sounds of the chest?
resonant throughout
What are abnormal percussion sounds of te chest?
dullness. - solid something in way ef. Tumour
Or Hyper resonance – too much air eg. Emphysema or pneumothorax
What are additional tests that can be done for respiration?
- Peak flow (blow into tube)
- Lung function treat s
- X-rays
- Sputum samples
- Capillary refill test
What is the pathophysiology of pneumonia?
- Infection of alveoli and bronchioles
- loss of mechanisms of keeping alveoli sterile
- Pathogens get into alveoli results in macrophages triggering inflammatory response and recruitment of neutrophils causing inflammation.
- Also results in leaky capillaries so alveoli fills with extroday which becomes populated with neutrophils, fibrin and erythrocytes
- Causes ‘consolidation’ which is pneumonia (can be sticky and concentrated in one lobe or patchy throughout whole lungs) as fills with neutrophils, erythrocytes and fibrin
- Narrow airways and reduced external respiration.
- Reduced Oxygen diffusion into blood, reduced lung expansion, patient feels SOB, resp rate and work of breathing increased
What would be different in a normal chest of someone without pneumonia?
Air below the bronchi is normally sterile due to cough reflex, muscocillary escalator, alveoli macrophages, immunogloblinaries, antibodies.
What are some signs and symptoms of pneumonia?
- Short of breath,
- using accessory muscles,
- work of breathing increased,
- unable to speak in whole sentences,
- increased respiratory rate,
- cough with green/rust coloured sputum which sometimes has blood in it. Can be haemopatist (blood in sputum). (can send off sputum sample) –
- pain (causing shallow breathing – exhaserbated the problem)
– cyanosis and hypoxemia
-tachycardia
– temperature increase
