25
Present this radiograph
* Initially, no name, Hospital Number, Date film taken * There is a marker * No AP / PA marker – assume AP * No indication of whether supine or erect – assume supine at start * Bowel dilated – * Position – central and bowel next to bowel * Folds (valvulae conniventes) go all way across * ie. Small Bowel Dilation * Need erect Chest X-Ray to exclude perforation
26
What does each number refer to in this radiograph?
* 1. Trachea * 2. Hilum – remember this comprises the bronchus, pulmonary blood vessels and the lymph nodes * 3. Lungs * 4. Hemidiaphragm * 5. Heart * 6. Aortic Arch * 7. Ribs * 8. Scapula or axilla * 9. Breast shadows * 10. Cardio-phrenic angle * 11. Costa-phrenic angle
27
What do you expect in a normal in a chest x-ray?
Position is PA and erect Cardio-thoracic ratio should be less than 50%
28
What is wrong in this CXR?

29
What is the pathology here?

30
How will a tension pneumothorax present?

34
35

37
A 21-year-old woman is thrown from her horse at a local event. On the way to hospital she has become increasingly drowsy and the paramedics have inserted an oropharyngeal airway and given high flow oxygen via a face-mask. Inspired oxygen 40% (FiO2 0.4) **ABG shows: ** normal values PaO2 18.8 kPa \>10 kPa (75 mmHg) on air pH 7.19 7.35 – 7.45 PaCO2 10.2 kPa 4.7 – 6.0 kPa Bicarbonate 23.6 mmol l-1 22 – 26 mmol l-1 Is the patient Adidotic or alkalotic?
Acidotic pH= 7.19
38
What does this ECG show and what is the sign callled?
Atrial flutter - Saw-tooth sign
39
What is happening in this ECG?
Atrial fibrillation
40
What does this ECG show?
Ventricular fibrillation
41
What does this ECG show?
Ventricular tachycardia
42
What are the shockable rhythms in cardiac arrest?
Ventricular fibrillation Pulseless ventricular tachycardia
43
What **inspiratory** sounds are there , where do the arise and what do the indicate?
**Snoring (Pharynx)**- obstruction by soft tissues, soft palate, epiglottis of the larynx and tongue. **Stridor (large diameter extrathoracic airways: larynx, trachea)- **indicates that the airway diameter is \< 50% or \< 4.5mm. **Hoarseness (larynx)- **Oedema as above, tumours, trauma. **Gurgling (pharynx)-** Liquid/semisolid: vomit, blood, secretions. **Crowing (larynx)- **Spasm of the laryngeal muscles: stimulation when the airway reflexes are intact eg with instrumentation. **Drooling (pharynx and larynx)-** Infection eg retropharyngeal abscess, acute epiglottis. Inability to swallow saliva.
44
What **expiratory** sounds are there?
Stridor Wheezing
45
What signs show hypercapnoea?

46
How do you open a patients airway without any equipment?
Head tilt, chin lift
47
What are the contraindications to performing head tilt/chin lift?

What do you do when an adult is conscious, choking with an ineffective cough?
5 back blows 5 abdominal thrusts
49
How long should it take to assess for 'signs of life' in a child before starting CPR?
