Sometimes … and monophonic

A

Wheeze - due to fast air flow through narrowed airways
Usually is expiratory, diffuse and polyphonic - asthma and COPD
Sometimes inspiratory and monophonic - if large central airway is narrowed - e.g by tumour

Q

Drug/medication HX Respiratory

A

Ask about inhalers as well as tablets
Some meds may cause respiratory symptoms
- Beta blockers for cardiac disease may cause SOB and wheeze
- ACE inhibitors for cardiac disease/ hypertension may cause cough
Some drugs may cause ILD - e.g. amiodarone, nitrofurantoin
Some drugs can cause pleural effusions (methotrexate)
Some meds may interact with ones we want to prescribe e.g. warfarin and Antibiotics, inhaled steroids and anti-viral drug
Always ask about allergies

17
Q

Family HX respiratory

A

Useful in suspected asthma if other family have asthma, hay fever or eczema
Important in infectious conditions such as TB (because of likely exposure through close contacT)
Cystic fibrosis and some causes of emphysema have a genetic basis

18
Q

Social Hx Respiratory

A

Smoking - current, when started and stopped (pack years, vaping, other drugs)
Occupation, e.g. exposure to asbestos
Pets - mammals and birds
Travel
Sexual Hx
Illicit drugs
Alcohol
Environment changes
Impact of breathlessness on ADLS
Home situation - who is at home

19
Q

Physical Exam - Respiratory - Signs outside the chest

A

Around the bed - Oxygen, weight, pursed lips, leaning forward, sats probe, cyanosed, food supplements, sputum pots, inhalers, cannulas, call bell

20
Q

Physical Exam - Respiratory - Chest

A

Inspection
Respiratory rate
Appearance of the chest
Movement of the chest - is it adequate? - is it equal on both sides?
Are there scars from previous surgery or trauma?
Palpation
Is the trachea central?
Chest expansion - often less reliable than inspection
Any lumps or tender areas
Percussion - Compare the degree of resonance over the same sites on each side
Percussion over normal lung is resonant, with dullness over the heart and the liver
Auscultation - listening with the stethoscope

21
Q

Causes of dullness to percussion (3)

A

Lung consolidation eg pneumonia

Lung collapse eg due to blocked bronchus

Pleural effusion eg due to infection, tumour or heart failure (NB This is common. Often “stony dull”)

22
Q

Percussion over normal lung is …, with …. over the heart and the liver

A

Percussion over normal lung is resonant, with dullness over the heart and the liver

23
Q

Auscultation - listening with the stethoscope (RESP)

A

The breath sounds are generated by turbulent air in the larynx and transmitted through the airways and lung tissue to the chest wall
Breath sounds are attenuated as they pass through normal lung
Normal breath sounds are called “vesicular”
Compare the same place on each side, front and back, top to bottom

24
Q

Auscultation - breath sounds

A

Breath sounds are decreased if there is fluid or collapsed lung present
Breath sounds are increased if there is consolidated lung between a bronchus and the chest wall - “bronchial breathing (sounds like listening over trachea)

25
Q

Added sounds - Auscultation

A

Wheeze - musical sound caused by air passing through narrowed airways, usually expiratory
- polyphonic versus monophonic
Crackles - usually inspiratory, due to popping open of blocked small airways e.g. lung fibrosis, pulmonary oedema
Pleural rub - creaking sound caused by friction of inflamed pleural surfaces e.g. pleurisy due to infection. May be inspiratory and expiratory

26
Q

Stridor

A

Is different to wheeze
Harsh inspiratory noise
High pitched
Indicates significantly obstructed airway-supraglottis, glottis, subglottis, trachea
You can hear it from end of the bed
Emergency-ENT asap

27
Q

Voice sounds

A

Ask the patient to say “ninety-nine”, or “one, one, one”
Reduced vocal resonance is caused by pleural fluid or lung collapse
Increased vocal resonance occurs in the same situations as bronchial breathing. When extreme there may be “whispering pectoriloquy”
Voice vibrations can also be felt “tactile fremitus”

28
Q

… vocal resonance occurs in the same situations as bronchial breathing. When extreme there may be “whispering pectoriloquy”

A

Increased vocal resonance occurs in the same situations as bronchial breathing. When extreme there may be “whispering pectoriloquy”

29
Q

… vocal resonance is caused by pleural fluid or lung collapse

A

Reduced vocal resonance is caused by pleural fluid or lung collapse

30
Q

At the bedside/bedside tests - RESP

A

Oxygen saturations
Target saturations and prescribe oxygen
94-98% if no history of COPD
88-92% if COPD, controlled oxygen
PEFR
Monitoring treatment of patients with asthma
To see of asthmatics meet criteria for D/C
Bedside spirometry (FEV1, FVC, FEV1/FVC)
Obstructive
Restrictive

31
Q

Peak Flow Rate - RESP - useful for?

A

Easy to perform
Useful for:
Supporting Diagnosis of asthma
Monitoring day to day variation
Picking up exacerbations-personalised asthma action plan
Assessing response to treatment
Needed for patients with asthma in hospital

32
Q

PEF - Morning Dips & ICS

A
33
Q

Arterial Blood Gases

A
  • Measuring a number of different things
  • pH: Acid-Base status
  • Gas tensions

–O2

–CO2

  • But also lactate, Hb, electrolytes, glucose, carbon monoxide
  • Be methodical-look at all the information
  • Record % inspired oxygen ABG was taken on
34
Q

What is shown here?

A

Right pneumothorax
