Smoke Inhalation

WHAT YOU SHOULD KNOW:

• Smoke inhalation is a condition where you breathe in harmful smoke. Harmful smoke comes from burning materials and gases, and contains small particles that are suspended in hot air. These small particles include chemicals, irritants, or toxins (poisons), such as carbon monoxide and cyanide. With smoke inhalation, the lungs and airways become irritated, inflamed (swollen), and blocked. The damaged airways and lungs prevent oxygen from getting into your blood, and respiratory failure may then develop. Respiratory failure means you cannot breathe well enough to get oxygen to the cells of your body.
  
  
• Smoke inhalation most commonly happens when you get trapped inside a burning structure, such as houses and buildings. Signs and symptoms of smoke inhalation include cough, hoarseness, headache, and trouble breathing. You may also faint (pass out), vomit (throw up), or have problems seeing or thinking clearly. Smoke inhalation can be diagnosed by bronchoscopy, blood tests, chest x-ray, blood gases, or pulmonary function tests. Treatment aims at relieving the signs and symptoms of smoke inhalation. It may include medicines, hyperbaric oxygen therapy, intravenous (IV) fluids, oxygen, and a mechanical ventilator. It is important to follow safety rules and guidelines to prevent smoke inhalation. With proper treatment, you have a greater chance of having a full recovery.

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:

• Smoke inhalation is a serious, life-threatening injury, and treatment should be given as soon as possible. If it is not treated early, the smoke may badly damage your lungs and cause further breathing problems. Your lungs may become infected, very swollen, and filled with fluid. Fluid in the lungs causes severe shortness of breath and may lead to respiratory failure. This may affect your heart and brain, and even lead to death.
  
  
• Sometimes, treatment for smoke inhalation may cause unwanted side effects. Medicines may cause you to have rashes, nausea (upset stomach), vomiting, or stomach ulcers (sores). Too much pressure on your lungs may cause air leaks or holes. Ask your caregiver if you have questions or concerns about your condition, medicines, or care.

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.

Rest:

Keep the head of your bed raised to help you breathe easier. You can also raise your head and shoulders up on pillows or rest in a reclining chair. If you feel short of breath, let caregivers know right away.

Deep breathing:

This exercise should be done once an hour to keep you from getting a lung infection. Deep breathing opens the tubes going to your lungs. Slowly take a deep breath and hold the breath as long as you can. Then let out your breath. Take 10 deep breaths in a row every hour while awake. You may be asked to use an incentive spirometer to help you with this. Put the plastic piece into your mouth and slowly take a breath as deep and as long as you can. Hold your breath as long as you can. Then, let out your breath.

Intake and output:

Caregivers will keep track of the amount of liquid you are getting. They also may need to know how much you are urinating. Ask how much liquid you should drink each day. Ask caregivers if they need to measure or collect your urine.

IV:

An IV (intravenous) is a small tube placed in your vein that is used to give you medicine or liquids.

Medicines:

You may be given the following medicines:

• Antibiotics: This medicine is given to help treat or prevent an infection caused by bacteria.
  
  
• Antidotes: These are substances that may stop or control the effects of the harmful smoke you inhaled. Caregivers may give different antidotes depending on the possible cause of your smoke inhalation.
  
  
• Bronchodilators: You may need bronchodilators to help open the air passages in your lungs, and help you breathe more easily.
  
  
• Medicines to treat pain, swelling, or fever: These medicines are safe for most people to use. However, they can cause serious problems when used by people with certain medical conditions. Tell caregivers if you have liver or kidney disease or a history of bleeding in your stomach.
  
  
• Steroids: Steroid medicine may help to open your air passages so you can breathe easier.

Neurologic exam:

This is also called neuro signs, neuro checks, or neuro status. A neurologic exam can show caregivers how well your brain works after an injury or illness. Caregivers will check how your pupils (black dots in the center of each eye) react to light. They may check your memory and how easily you wake up. Your hand grasp and balance may also be tested.

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.

Tests:

You may have any of the following:

• 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.
  
  
• Bronchoscopy: This test may be done to look inside your airways and lungs. Caregivers use a bronchoscope to do this test. It is a long tube with a light and magnifying glass on the end. The scope goes in your mouth and into your lungs. Your caregiver may give you medicine for pain or to help you relax during the bronchoscopy. Caregivers may also do a bronchoalveolar lavage through the scope. This is when fluid and cells are sucked up from your lungs to be sent to the lab for tests.
  
  
• 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.
  
  
• Computerized tomography scan: This test is also called a CT or CAT scan. A special x-ray machine uses a computer to take pictures of your lungs. Before taking the pictures, you may be given dye through an IV in your vein. The dye helps the lungs, heart, and blood vessels show up better in the pictures. People who are allergic to iodine or shellfish (lobster, crab, or shrimp) may be allergic to this dye. Tell your caregiver if you are allergic to any of these.
  
  
• Pulmonary function tests: Pulmonary function tests, also called PFTs, help caregivers learn how well your lungs work. PFTs may also help your caregivers decide on the best treatment for you. During the tests, 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. This helps caregivers to see how well your lungs are moving and working.
  
  
• V/Q Scan: This is a ventilation (V) and perfusion (Q) test. This test is also called a VP scan. A V/Q scan is a two-part test which takes pictures of your lungs to look for certain lung problems.
  
  
  • During the perfusion part of the test, radioactive dye is put into your vein (blood vessel). The blood carries the dye to the blood vessels in your lungs. Pictures are taken to see how blood flows in your lungs.
    
    
  • During the ventilation part of the test, you breathe in special gas. Pictures are taken to see how well your lungs take in oxygen.

Treatment options:

You may need any of the following:

• Hyperbaric oxygen therapy: This is also called HBO. HBO is used to get more oxygen into your body. The oxygen is given under pressure to help it get into your tissues and blood. You may be put into a tube-like chamber called a hyperbaric or pressure chamber. You will be able to see your caregivers and talk with them through a speaker. You may need to have this therapy more than once.
  
  
• 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.
