Introduction

Severe asthma attacks can happen in a very short time, but with the proper response, you will be able to help keep the situation under control and possibly save a life. Whether you have been diagnosed with asthma or you are taking care of someone diagnosed with this chronic condition, knowing what to do in an emergency is critical. The most important thing when it comes to dealing with a severe asthma attack is timely treatment. With the proper steps taken, you will be relieving symptoms and keeping them from turning into a life-threatening situation.

An asthma exacerbation is an exacerbation or sudden increase in symptoms of asthma, and these episodes, if not cared for immediately, can rapidly deteriorate into respiratory failure. However, do not be alarmed; being aware of how one is supposed to act in such a case dramatically changes the outcome. The following steps highlight the best course of action for a person experiencing a severe asthma attack.

Understanding severe acute asthma exacerbations

Asthma exacerbation or flare-up involves a sudden and significant worsening of symptoms, usually related to allergens, respiratory infections, exercise, or other irritants. In the case of severe exacerbations, medical help is usually required in the form of an emergency, as the airways become so inflamed and narrowed that they severely restrict airflow to the lungs.

In a severe asthma attack, symptoms extend much further from usual wheezing or slight breathlessness. 

These signs include extreme shortness of breath, tight chest, difficulty with speech or walking, and a need to use accessory muscles, e.g., the neck and chest muscles, when breathing. In addition to this, there are cyanosis-lips and the face turning blue due to an extremely low level of oxygen in the blood. According to the Global Asthma Report 2022, approximately 10% of people with asthma suffer from frequent exacerbations, which lead to the high admission rates seen in the hospital. In these situations, the need for a rapid response is often indicative of medical intervention to prevent respiratory failure.

Recognising the signs of a severe asthma attack and taking immediate action is crucial in preventing life-threatening outcomes.

Emergency response steps

Call for emergency help

When you identify the signs of an acute asthma attack, the most relevant and important intervention is to immediately provide your patient with professional help. One should call the emergency services unless the person has severe difficulty breathing, cannot say sentences, or develops a bluish colouration of the lips or fingernails. In most asthmatic patients, acute asthma attacks may worsen within minutes, and delays in medical attention may result in complications such as respiratory failure and even death.

If you're ever in doubt about whether symptoms merit an emergency call, err on the side of caution; it's always better to be safe than sorry when it comes to severe asthma.

Administer quick-relief medications

After seeking emergency assistance, the course of action would be the administration of a quick-relief inhaler or nebuliser. The strongest among the immediate treatments for exacerbation of asthma includes SABAs, such as albuterol. These agents work by relaxing the muscles surrounding the airways and dilating them to improve airflow.

To administer the inhaler properly:

• Shake the inhaler well
• Have the patient sit up straight, then exhale fully
• After inhaling the medication, instruct them to hold their breath for about 10 seconds to allow the medicine to settle in the lungs

If the patient has a nebuliser available, this is also employed for longer-lasting relief. Nebulisers give liquid medication in a fine, foggy mist inhaled over several minutes, providing deeper and more sustained access to the lungs. The patient's asthma action plan indicates which form of quick-relief medication to use, but in an emergency, any available rescue medication could be critical.

With severe asthma, patients may need several doses of quick-relief inhalers. Most of the action plans recommend 2 to 4 puffs every 20 minutes for up to an hour, but always follow the specific instructions from your health provider.

Monitor breathing and oxygen levels

While waiting for the emergency services to arrive, it will be important to continue monitoring the patient's breathing and levels of oxygen. This is where a pulse oximeter could be invaluable in assessing the severity of the attack. The normal and healthy range of oxygen saturation usually lies between 95% and 100%. In severe asthma attack cases, however, oxygen may fall below 90%, and such interventions become critical.

There are also hints to watch out for even without the pulse oximeter. Shallow or fast breathing, a pale or bluish tinge to the skin, and application of accessory muscles-neck or chest-might all be used in breathing. If they start to fade in and out of consciousness, or can't speak in full sentences anymore, this means that things are becoming serious.   

Use an asthma action plan

The asthma action plan is an individualised plan developed with the healthcare provider that describes ways to control asthma symptoms daily and what should be done if an attack occurs. If the patient has one, follow the action plan closely. This will include how to handle different stages of an asthmatic attack: which medications are taken, when to seek medical assistance.

Even without a specific action plan, the steps are similar: administer quick-relief medications, call emergency assistance, and keep the patient calm and in an upright position to maximise airflow to the lungs.

Stay calm and keep the patient upright

One of the most significant things one can do while experiencing an asthma attack is to remain as composed as possible. Exacerbation of asthma is a fearfully threatening experience, and panic only worsens the situation because it increases the patient's heart rate and exacerbates the difficulties in breathing. Encourage the patient to stay upright, as this helps open up the airways and makes breathing easier.

Have the patient sit up straight and not lie down, as this will further compress the lungs, constricting airflow. Provide reassurance to the patient and guide them through slow, controlled breathing as you wait for further help.

Administer additional medications, if prescribed

This would also include the use, in some cases, of extra medications that could be used during an asthma attack. They reduce inflammation in the airways and are usually used to treat severe, persistent asthma. These medications should only be used in relation to prescribing and should be included in the patient's asthma action plan. Corticosteroids take longer to begin acting, but can prevent the attack from becoming worse.

Long-term control medications, such as inhaled corticosteroids, are used to prevent exacerbation of asthma and are not helpful during an acute attack. Never rely on these during a crisis- always use a short-acting bronchodilator first.

Stay with the patient until help arrives

It is also vital to stay with the patient until emergency services arrive. Reassurance should be continually provided, and medication, where possible, assisted with, while watching for symptoms carefully. Sometimes, the sufferer of asthma becomes too weak or confused to give themselves medication; therefore, being nearby can be lifesaving.

Why are these steps critical?

All these measures are to nip the severe asthma attack effectively and efficiently. The quick-relief medication will open up the airways very fast, the monitoring of the oxygen level and calling for emergency assistance shall ensure that the patient gets the required care as quickly as possible. Asthma, if not timely treated, can result in respiratory failure in extreme cases, wherein a minute can make all the difference.

Long-term management of asthma is equally important in preventing future emergencies. You can reduce the frequency and severity of asthma exacerbations by learning more about ongoing asthma care; thus, it offers a better quality of life.

Preventing future asthma exacerbations

Many advanced steps taken consistently prevent severe asthma attacks. Control medications for the long term are prescribed to many patients, including inhaled corticosteroids, which act to decrease chronic inflammation of the airways. For medications of these types to be effective at controlling symptoms, they must be taken regularly.

Thirdly, patients must be made aware of their asthma triggers. The common asthma triggers are allergens that include pollen, dust mites, and pet dander; environmental factors like smoke and air pollution; and respiratory infections. Thus, by avoiding these triggers identified, asthma sufferers can reduce their risk of exacerbation considerably.

It is relevant that there should be regular check-ups with a doctor or other healthcare professional. Asthma control is not one-size-fits-all, and symptoms and triggers may change over time, which can necessitate an adjustment in treatment. It's highly advisable to update an asthma action plan at least once annually so that it can be current and function well.

Having a supply of quick-relief medications on hand for emergencies and ensuring that family members or caregivers know the asthma action plan can make all the difference at times of unexpected flare-ups.

Summary

Knowing precisely what to do in case of a heavy asthma attack may be lifesaving. The essence of such actions is calling emergency help, administering medications for quick relief, observing the breathing, and generally being with the patient until help arrives. Having an action plan for asthma is as important as being calm during the emergency for its effective management.

Prevention through long-term asthma management and trigger avoidance is as important as responding to emergencies. Patients with asthma can prevent severe exacerbations by staying on top of daily care and preparing for emergencies.
