1

Medical/Respiratory Disorders affecting the Respiratory System Name conditions

Asthma Chronic bronchitis Emphysema Pneumonia Pulmonary embolus

2

Asthma 4 presentations

Mild/moderate Severe Life-threatening Near fatal

3

Asthma can be triggered by a number of factors e.g.

allergens (pollen, dust, foodstuffs), aspirin, infection, stress, cold air or smoke

4

Pathology of asthma

The initial reaction involves spasmodic contraction of the bronchi and bronchioles. Inflammation of the bronchi and bronchioles. Increased mucus secretion. Oedema may follow to further complicate the condition.

5

Adult Asthma

Acute Severe Asthma Unable to complete a sentence in one breath Respiratory rate >25 Heart rate >110 PEF 33% - 50% of predicted normal Life Threatening Asthma Silent chest Cyanosis Poor respiratory effort Bradycardia or hypotension Exhaustion, confusion, coma PEF <33% of predicted normal SpO2 <92%

6

Asthma in Children

Acute Severe Asthma SpO2 <92% on air Too breathless to talk or feed Respiratory rate >50 (2 – 5 yrs), >30 (5 – 18yrs) Heart rate >130 (2 – 5 yrs), >120 (5 – 18 yrs) PEF <50% of predicted normal Life Threatening Asthma - SpO2 <85% in air Silent chest Cyanosis Poor respiratory effort Fatigue or exhaustion Agitation or reduced conscious level PEF <33% of predicted normal

Management of Asthma (1)

Ensure ABC’s

Administer Oxygen therapy if hypoxaemic (maintain SpO2 94-98%)

Consider patient position

Commence transport

Specifically consider:

Check peak flow if practicable – note the best of 3 Administer Salbutamol

In acute severe or life threatening cases Ipratropium should be administered with the salbutamol

9

Management of Asthma (2) In cases of hypoventilation consider

in-line nebulisation with BVM and nebuliser

Monitor using ECG and Pulse Oximeter

Repeat doses of Salbutamol in accordance with guidelines

Exclude pneumothorax

Monitor and reassess to evaluate any change in peak flow or air entry

Consider Paramedic support to administer Hydrocortisone where there is a delay getting to hospital of >30 minutes

10

Treatment of Life Threatening Asthma

Adrenaline 1:1000 IM/SC – repeated after 5 minutes if necessary)

Salbutamol / Ipratropium Bromide

Paramedic support for IV access [do not delay transport]

Paramedic will administer Hydrocortisone IV (if >30 minutes to hospital)

In-line nebulisation with bag, valve, mask in cases of hypoventilation.
