Respiratory Assesment Flashcards
External Signs of Respiratory Distress
- Wheezing/coughing/gurgling
- Abnormal resp rate
- Anxiety
- Cyanosis/buccal mucosa
- Flared nostrils/pursed lips
- Intercostal recession
- Positioning eg tripod position
- Reduced lvl of consciousness
- Unable to complete a sentence in one breath
- Use of shoulder and neck accessory muscles
Environmental Indicators
- Cigarettes
- Home oxygen
- Medication - inhalers
- Infection
- Smells - gas, damp
- Chemicals, farming, fire
Meaning of Abnormal Auscultation; gurgling, snoring, stridor, wheezing
- Gurgling - fluid in the airway
- Snoring - partial occlusion caused by relaxed tissue eg tongue
- Stridor - partial obstruction of larynx or trachea
- Wheezing - lower respiratory - narrowing/inflammation
Breathing Assessment Steps (6)
- Obtain resp rate
- Expose and examine pt’s chest
- Palpate chest feeling for equal rise and fall, crepitus, tenderness, abnormalities. Feel for trachea being in the midline (sign of pneumothorax)
- Percuss for hypo/hyperresonance
- Auscultate for abnormal sounds
- Measure SpO2 and EtCO2
PC Questions
Do you have any pre-existing respiratory health problems? (asthma, COPD, emphysema, lung cancer)
Do you have any shortness of breath?
Is this normal for you?
Do you have any other symptoms?
Are these new or old?
HPC Questions
When did the problems start?
What were you doing when the problems started?
Has this ever happened before?
Do you have a cough? (dry? productive? sputum? yellow/green=infection, pink frothy=pulmonary oedema, blood?
Have you taken any prescribed medication? Did it help?
Do you have any pain, if so where?
PMH Questions
- Are you diagnosed with anything? specifically COPD, asthma and heart disease.
- Do you take any regular medication?
- Any allergies?
- Do you smoke?
Peak Expiratory Flow, what does it measure? Percentages for Asthma
Measures adequacy of ventilation, in the form of forced expiratory volume (FEV). Essential for asthmatic pt’s
- 33-50% (acute asthma)
- > 33% (life-threatening)
- In severe dyspnoea, pt may be unable to perform task
- Peak flow meter with a disposable mouth piece
- PEF should be recorded as best of 3 then compare to PEF flow chart or known normal value
- Take recordings pre and post treatment to note effectiveness
Ur looking at the chest, what coud be there?
Respiratory Assessment; Inspection. What are we inspecting for?
- Expose the chest incl posterior, anterior and axilla surfaces
- Chest wall marking = wounds, bruising, bleeding, swelling
- Implanted devices = pacemaker, implantable cardioverter defibrillator (ICD)
- Medication patches = analgesia, glyceryl trinitrate (GTN), nicotine
- Normal chest shape and equal rise
- Rashes = hives indicative of allergy or petechial haemorrhage indicative of meningoccal septicaemia (Meningitis)
- Resp rate noting abnormal patterns (Kussmaul’s, Cheyne-stokes)
- Scars with credible history
Respiratory Assessment; Where to Palpate (what to look for)
- Use both hands/finger to palpate the anterior, posterior and axilla walls starting above each clavicle then systematically progress down the anterior chest wall followed by posterior chest wall then axilla. Note:
-crepitus - fractures
-surgical emphysema - popping under the skin caused by trapped air
-Tenderness - bruising, muscle dmg
Respiratory Assessment; Palpate, Auscultation, Consolidation in pneumonia
- Palpate for equal and bilateral air entry. This can be done by placing your hands on each posterior wall w/ their thumbs meeting in the middle at the spine
- Equal and symmetrical hand movement should be seen where the thumbs separate and return to the same position at the same time. Lack of symmetry = problem to the thorax
- Using the steth, get pt to say ‘99’ while moving over the anterior/posteriori/axilla points of the chest
- Consolidation for pneumonia increases fremitus and decreases air entry eg emphysema decreases fremitus
How to Percuss and Where
- Must be in a clam and quiet environment to perform
- The percussing finger is the middle finger with the opposites hands’ finger used to strike the other onto the chest
- Percussion starts above the clavicle, moving down every 3-4cm. Compare both sides
- Don’t percuss the scapula
- Percuss to the 6th rib anteriorly and to the 8th rib of the axilla and the 10th rib posteriorly
Percussion Sounds and what they mean
Normal Lung - resonant
Pneumothorax - hyper ressonant at site
Empysema (COPD) - bilateral hyper ressonant
Fluid - Dull
Abnormal Auscultation Sounds; Apnea, Coarse Crackles, Expiratory Wheeze, Fine Crackles, Inspiratory Wheeze, Pleural Rub
- Absence/Apnea - life threatening eg pneumothorax
- Coarse Crackles - insp/exp due to fluid or sputum in larger airways (indicative of pneumonia)
- Expiratory Wheeze - air forced through small spaces (indicative of COPD)
- Fine Crackles - sound created at the end of expiration by the reopening of small airways. Or air passing though intra-alveolar fluid, normally heard in the basal lung fields (indicative of pulmonary oedema)
- Inspiratory Wheeze - high pitches (indicative of foreign body obstruction)
- Pleural Rub - creaking on deep inspiration/expiration (indicative of pleurisy)
Mechanical Factors Affecting Respiratory System
- Abdo Distension - due to fluid from ascites, impacted faces, fat, foetus, flatus (5F’s)
- Obesity - w/ increased weight on the chest, requires more effort to breath normally. Also, increased abdo mass may impede lung expansion
- Pregnancy - gravid female may not be able to expand lungs due to splinting of the diaphragm by the in-sita foetus
What is Anaphylaxis?
A severe, life threatening hypercreativity reaction that is characterised by rapidly developing life-threatening problems that involve the airway, (pharyngeal or laryngeal oedema) breathing (bronchospasm with tachypnoea) and/or circulation (hypotension and/or tachycardia)
Obs (3) Symptoms (4) Signs (4)
