Moderate And Severe Persistent Asthma

WHAT YOU SHOULD KNOW:

• Asthma is a long-term condition where your bronchial tubes swell and tighten. The bronchial tubes are airways that carry air in and out of your lungs. An asthma attack (episode of asthma) usually happens after you are exposed to triggers. Triggers are things you breathe in or things you do that give you an asthma attack. These include dust, smoke, chemicals, heavy exercise, and changes in weather. During an asthma attack your airways swell, and the small muscles in your airways tighten. When the airways become too narrow, less air flows to your lungs and you have trouble breathing.
  
  
• Your caregiver will ask about medical problems that you have had, and do a complete exam on you. He will ask what causes you to have an asthma attack, and what your symptoms are. You may be tested for allergies. You may have blood and peak flow tests, pulmonary function tests, and x-rays. You and your caregiver will work together to decrease your symptoms and prevent asthma attacks. Your caregiver will give you asthma medicines and teach you when and how to use them. He may change your medicines if your symptoms get better or worse. There is no cure for asthma, but the condition can be controlled, and asthma attacks can be prevented.

CARE AGREEMENT:

You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.

RISKS:

• Medicines for asthma may make you dizzy and increase your heartbeat. Some medicines, such as steroids, can make you gain weight and can cause skin problems such as acne. You may also be at a higher risk of getting mouth infections and a sore throat.
  
  
• If your asthma is left untreated, you can have more and longer asthma attacks. Your symptoms can get worse. Your airways can grow thicker, letting less air through them. Your air sacs may fill with mucus. Your lung tissue can get damaged and scarred. This can lead to other conditions such as emphysema and chronic obstructive pulmonary disease (COPD). Your asthma may get very bad, and you could die. Ask your caregiver if you have questions about your condition, medicines, or treatments.

WHILE YOU ARE HERE:

Informed consent:

A consent form is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.

Medicines:

You may need any of the following:

• Antibiotics: This medicine is given to help treat or prevent an infection caused by bacteria.
  
  
• Bronchodilators: You may need bronchodilators to help open the air passages in your lungs, and help you breathe more easily.
  
  
• Steroids: These medicines help decrease swelling and open your air passages so you can breathe easier. Low to medium doses of inhaled (breathed in) steroids are used in moderate persistent asthma. Oral (medicine taken by mouth) steroids together with higher doses of inhaled steroids are needed in severe persistent asthma.

Tests:

• Blood gases: This is also called an arterial blood gas, or ABG. Blood is taken from an artery (blood vessel) in your wrist, arm, or groin. Your blood is tested for the amount of oxygen and carbon dioxide in it. The results can tell caregivers how well your lungs are working.
  
  
• Blood tests: You may need blood taken to give caregivers information about how your body is working. The blood may be taken from your hand, arm, or IV.
  
  
• Heart monitor: This test is also called an EKG or ECG. Sticky pads are placed on your skin to record your heart's electrical activity. An EKG gives information about how your heart is working. Lie as still as possible during the test.
  
  
• Pulmonary function tests: Pulmonary function tests (PFTs) help caregivers learn how well your body uses oxygen. You breathe into a mouthpiece connected to a machine. The machine measures how much air you breathe in and out over a certain amount of time. PFTs help your caregivers decide the best treatment for you.
  
  
• Pulse oximeter: A pulse oximeter is a device that measures the amount of oxygen in your blood. A cord with a clip or sticky strip is placed on your finger, ear, or toe. The other end of the cord is hooked to a machine. Never turn the pulse oximeter or alarm off. An alarm will sound if your oxygen level is low or cannot be read.
  
  
• Chest x-ray: This is a picture of your lungs and heart. Caregivers use it to see how your lungs and heart are doing. Caregivers may use the x-ray to look for signs of infection like pneumonia, or to look for collapsed lungs. Chest x-rays may show tumors, broken ribs, or fluid around the heart and lungs.

Treatment options:

• Breathing treatments: You may need breathing treatments to help open your airways so you can breathe easier. A machine is used to change liquid medicine into a mist. You will breathe the mist into your lungs through tubing and a mouthpiece. Inhaled mist medicines act quickly on your airways and lungs to relieve your symptoms.
  
  
• Endotracheal (ET) tube: An endotracheal tube may be put into your mouth or nose. It goes down into your windpipe to help keep your airway open and help you breathe. It may be hooked to a ventilator (breathing machine), and you may get extra oxygen through your ET tube. You will not be able to talk while the ET tube is in place.
  
  
• Oxygen: You may need extra oxygen if your blood oxygen level is lower than it should be. You may get oxygen through a mask placed over your nose and mouth or through small tubes placed in your nostrils. Ask your caregiver before you take off the mask or oxygen tubing.
  
  
• Ventilator: This is a machine that gives you oxygen and breathes for you when you cannot breathe well on your own. An endotracheal (ET) tube is put into your airway through your mouth or nose. You may need a trach if an ET tube cannot be placed. A trach is an airway tube put into an incision (cut) in the front of your neck. The ET tube or trach is attached to the ventilator.
