Respiratory System Vocabulary
Respiratory System Key Terms:
- Respirations Breathing in and out
- Inhale/inspiration To breath in
- Exhale/expiration To breath out
- Trachea “wind pipe” hollow tube that has rings of cartilage to prevent collapse. Carries air to and from the lungs from the mouth and nose.
Diaphragm Muscular layer that lies just below the lungs, responsible for contracting and relaxing as it facilitates inhaling and exhaling.
Sternum Boney structure that connects the ribcage. It is strong and helps protect the heart and lungs. “Breast Plate”
Respiratory distress Distress = Difficutly BREATHING
Respiratory arrest Arrest = Breathing Stops completely
Dyspnea Dys means difficult
means Breathing so…
Dyspnea means Difficult Breathing
Apnea A means not or absence so it means Absence or NOT breathing
Cyanosis Cyan means BLUE Osis means any condition of so….it means a condition of being blue. When we don’t get enough oxygen..the tissues turn a blueish color. Expecially the skin around the mouth, fingers and toes and the nail beds
Asthma Asthma is a chronic “continuous and ongoing” disease involving the airways in the lungs. These airways, or bronchial tubes, allow air to come in and out of the lungs. With asthma, certain conditions trigger a “spell” which causes a narrowing/constriction of the bronchial tubes and dyspnea.
- Allergic reaction Can be mild with minor itching etc. Life threatening symptoms can arise when the allergic reaction is severe and impedes the breathing process by narrowing the bronchial tubes and/or causing swelling in the mouth or throat which can block the airway.
- Anaphylactic shock Is defined as a serious, life-threatening allergic reaction! The most common anaphylactic reactions are to foods, insect stings, medications. If you are allergic to a substance, your immune system overreacts to this allergen by releasing chemicals that cause allergy symptoms.
23) Epi pen Is an Auto (self) injector. A medical apparatus that is used to in emergency situations to deliver an injection of the drug Epinephrine. People who have serious issues with allergies may be prescribed one by their doctors. They are supposed to keep it with them and use it in breathing emergencies. It is referred to as an Auto-injector because they are taught to inject into their leg all by themselves. However, sometimes they need assistance in using it. You will learn how to do that in this course.
- Bradypnea Brady = slower than normal ( Brad like Braiding hair - so it means breathing really slow! Normal breathing is 12 to 20 times per minute or 20 rpm
- Inhaler - an apparatus or piece of medical equipment used to deliver medication directly into the lungs. Normally used for emergency situation involving someone who has asthma.
*** It cannot be Shared with anyone else!!
- Obstruction Means a blockage or barrier. When the airway becomes blocked with food or other small objects and we become choked…that is a fancy way of saying it “My patient is choking, they have an airway obstruction!”
- Bronchial tubes Tubes that branch off of the trachea and carry air to the lungs
- Alveoli tiny little grape-like clusters of microscopic air sacs that are attached to the bronchioles in the lungs. This is the place where gas exchange occurs. Oxygen in and Carbon Dioxide out.
- Aspiration A condition in which food, liquids, saliva, or vomit is breathed into the airways.
- Rescue breathing is basically breathing for the person, helping to prevent brain damage and death in the patient.
