Respiratory Flashcards
What does this show?
Moderate Chronic Obstructive Pulmonary disease
Lifestyle management Strategies for COPD
(5)
SPRINT
Stop smoking
Pulmonary Rehab + usual exercise recommendations
Regular reviews (start of careplan and have an action plan)
Immunisations especially pneumococcal and influenza
Nutrition- balanced diet and healthy weight
What is the treatment (and prophylaxis) for pertussis? with dosing
Clarithromycin: (child 7.5 mg/kg up to) 500 mg orally 12 hourly for 7 days
OR
Erythromycin: (child 10 mg/kg up to) 250 mg orally, 6 hourly for 7 days
How do you diagnose Asthma?
there is no one test.
- Spirometry that shows reversible airflow of > 12% AND 200ml (anything > 400ml is strongly indicative)
- Peak flow measurements. Over 14 days. If there is a greater than 20% difference between the highest and lowest measurements.
- Clinical assessment alone can be enough.
- Clinical trial/treatment trial to assess improvement.
What increases the possibility of an Asthma Diagnosis?
More than one of:
1- wheeze
2- chest tightness
3 - SOB
4- cough
AND
1- worse at night
2- occurs during exercise
3- occurs after exposure to cold air or allergens
4- occurs after NSAID or B-Blocker use
Other factors that increase possibility
-History of atopy: personal or family
-Widespread wheeze on auscultation
-Improvement with therapy
-Unexplained eosinophilia on bloods
What FEV1 measurements delineate the severity of asthma?
FEV1 > 80% predicted = mild
FEV 1 60-80% = moderate
FEV1 < 60% = severe
What main co-morbidities are important in asthma management?
(5)
Obesity
Anxiety and Depression
Allergic rhinitis and sinus issues - rhinosinusitis
GORD
Inducible laryngeal obstruction
What triggers should be avoided/be mindful off in asthma?
(5)
- Always avoid cigarette smoke
- Allergens- dust, pollen
- Drugs like NSAIDs, Beta Blockers
- Environment: cold air, occupational irritants, pollution
- Dietary triggers if patient has a food intolerance
What are the diet and exercise recommendations for asthma
Diet:
Mediterranean diet
Refer to the Australian Dietary Guidelines
Exercise
Regular exercise at usual recommendations still recommended.
What education should you cover with a patient regarding asthma?
(6)
1 what is asthma
2 rationale for treatment
3 difference in relievers and preventers
4 education in inhaler technique
5 potential adverse outcomes of treatment
6 what to do if there is an exacerbation
What is step 1 pharmacotherapy in all asthma patients?
As needed Salbutamol 100microg/puff in a MDI
1-5 years 2-6 Puffs, through a spacer , when needed
Children aged 6+ and adults
2-12 puffs, through a spacer, as needed
What is step 2 therapy in different aged patients for asthma?
(not including the SABA in step 1)
1-5 years old:
Fluticasone propionate 50-100micrograms Inhaled with a MDI, through a spacer, 12 hourly
(or other ICS)
OR
Montelukast 4mg, orally, daily
6-12 years old:
Fluticasone 50-100micrograms, by DPI or pMDI with spacer, 12 hourly.
(or other ICS)
OR
Montelukast 5mg, orally, daily.
In adults:
Same fluticasone dosing Or other ICS
Or
Montelukast 10mg, orally, daily
ORRR
Symbicort combination (no SABA needed)
budesonide + formeterol 100+6 micrograms, via a DPI or pMDI with spacer. taken WHEN NEEDED in step 2.
Step 3 Therapy for different age groups in asthma?
(not including reliever therapy).
Children 1-5 years
Increased ICS dose (fluticasone 125microg in pMDI with spacer, 12 hourly)
OR
normal ICS dose + montelukast 4mg, oral, daily
AND
refer
Children 6-12 years old
Increased ICS dose (e.g. fluticasone 125-250microgram in pMDI with spacer, 12 hourly)
OR
Normal ICS dose and 5mg Montelukast, oral, daily
Or
Normal ICS dose and low dose LABA (e.g. fluticasone + salmeterol 100+50micrograms inhaled using pMDI and spacer, 12 hourly)
Adults
First line: add a LABA to ICS
flucticasone +salmeterol 100+50micrograms inhaled via pMDI with spacer (or DPI) , 12 hourly
Second:
Higher dose ICS
Flucticasone 500micrograms inhaled via pMDI with spacer, 12 hourly
up to 1000micrograms
OR
Fluticasone normal dose (50-100 microg) + montelukast 10mg oral daily
OR
Symbicort option regular 100+6 (or 200+6) micrograms, via DPI, 12 hourly
+ PRN Symbicort
(patient needs to fail other therapy first)
what should asthma reviews ALWAYS consist of checking?
What 2 other things can you check?
(2) +(2)
Inhaler technique
Adherence
Check comorbidity management (e.g. rhinitis)
Check avoidance or presence of triggers
What is the follow up time frame for asthma?
4-6 weeks after initiating therapy
then 12 monthly if no exacerbations
or 6 monthly if 1 exacerbation in the last 12 months
or 3 monthly if poor perceiver, or frequent exacerbations.
What is poor control of asthma defined as in an adult? vs Child?
ADULTS
Three or more of the following
- > 2 days of daytime symptoms
- > 2days of SABA use
- any limitations of activities
- any symptoms at night or wakening
CHILDS
Either of
A. daytime symptoms on more than 2 days a week lasting for minutes to hours, recurring or only partially relieved by SABA
B. Three or more features of partial control !
Partial control for a child:
one or two of the below
(same as above for adults)
NB limitation of activities is wheeze or breathlessness during exercise, play or laughter
What are the symptoms and how do you diagnose COPD?
Breathlessness
Wheezing
Cough
Sputum production
Recurrent infection
FEV1/FVC < 0.7 (post bronchodilator)
What do you use to diagnose COPD on spirometry and what do you use, with cut offs to define Severity?
FEV1/FVC ratio of <0.7 post bronchodilator to diagnose COPD
USE FEV1 alone to judge severity
> 80% would be unlikely to happen
60-80% is mild
40-60% is moderated
<40% is severe
What is the first step in treatment (pharmacological) in treating COPD?
Start with a SABA or SAMA
SABAs are preferred.
For COPD what are long acting medications that can be added to SABAs and general measures?
- LAMA
e.g. Tiotropium 13-18micrograms, DPI, daily - LABA
the LABA that is PBS approved for COPD is indaceterol
150micrograms, DPI, daily
