Asthma Treatment & Control in London

Asthma control is a measure of the reduction in symptoms, prevention of exacerbation, and maintenance of good lung function. Current guidelines state that well controlled asthma requires no symptoms, no exacerbation, and normal lung function.

A friendly team of allergy,  immunology and respiratory medicine consultants as well as ENT surgeons will do our best to look after patients with allergic and non-allergic asthma as in a multi-disciplinary approach.

People with aspirin sensitivity NSAID-Exacerbated Respiratory Disease (NERD) can develop symptoms of several conditions lined to Aspirin-exacerbated respiratory disease (AERD), also known as Samter’s Triad.

The condition is named after an immunologist, Max Samter, who first identified it, while ‘Triad’ refers to the three key components involved. Asthma, aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) sensitivity, and nasal polyps make a complex chronic medical condition  that requires several specialities to be involved.  

We do assessment for biological treatment (monoclonal antibodies) of patients with severe asthma and nasal polyps.

Health professionals should tailor asthma review to allow for patient preference (including frequency of professional review), as well as asthma severity, risk of severe attacks, and the type of maintenance treatment plan in place.

Peak Flow Diary

This great site helps you (and your doctor) to monitor your asthma

Step 1 – Record

The first step is to record your peak flow reading, using the form shown below. The form is simple just time, date and reading.

Step 2 – View Chart

Your peak flow readings are then plotted on the graph.

Peak Flow Meter

Peak Flow Predicted values for Adults View Chart

You will need to match your age and height on the chart.

Peak Flow Predicted values for children


Is the new EU-scale meter the same as the ATS-scale meter?

No.  Whilst the scale may look similar, only meters that display the text ‘EN 13826‘ have been tested to the new standard.  The EN13826 standard includes two important ‘airflow waveforms’ that are not part of the ATS test procedure for peak flow meters. Some ATS-scale meters have already been shown as failing the new EN 13826 standard .

Spirometry Calculator

Asthma severity is based on clinical features, as defined in the following table:

Classification Day-time symptoms Night-time symptoms PEFR* PEFR variability**
Intermittent 1 time per week or less Twice per month or less =/>80% <20%
Mild persistent 1 time per week or more but less than once per day Twice per month or more =/>80% =20-30%
Moderate persistent Daily Once a week or more =60-80% 30%
Severe persistent Daily Frequent =/<60% 30%
*PEFR = peak expiratory flow rate as a percentage of expected PEFR according to patient age and height
**PEFR variability = the difference between morning and evening flow rates

The Global Asthma Report 2011

Asthma affects 235 million people today and prevalence is rising. Low- and middle-income countries suffer the most severe cases.

We have the tools to counter the devastating personal and economic impact of untreated and poorly managed asthma.

The British Asthma Guideline recommends the Royal College of Physicians three questions to assess asthma control over the preceding month.

Have you had any difficulty sleeping because of asthma symptoms, have you had your usual asthma symptoms during the day, and has your asthma interfered with your usual activities?

A personal asthma action plan is a tailored written record of what action to take when symptoms or peak flow readings deteriorate. It includes information about when the patient needs to seek medical help or emergency care. This encourages the patient to take more responsibility for their asthma management.Patients should be given autonomy to step up and step down their treatment as detailed in their asthma action plan, in response to their symptoms or peak flow monitoring.
