Term | Definition |
---|---|
Apnea | A condition that causes breathing to stop periodically or be significantly reduced. |
Artificial ventilation | A mechanical means used to assist breathing, such as with a bag-valve-mask resuscitator (BVM) or resuscitation mask. |
Aspiration | To take, suck or inhale blood, vomit, saliva or other foreign material into the lungs. |
Asthma | An ongoing condition in which the airways swell; the air passages can become constricted or blocked when affected by various triggers. |
Asthma attack | The sudden worsening of asthma signs and symptoms, caused by inflammation of the airways and the tightening of muscles around the airways of a person with asthma, making breathing difficult. |
Asthma trigger | Anything that sets off an asthma attack, such as animal dander, dust, smoke, exercise, stress or medications. |
Bag-valve-mask resuscitator | A hand-held breathing device consisting of a self-inflating bag, a one-way valve and a face mask; can be used with or without emergency oxygen. |
Breathing emergency | An emergency in which breathing is impaired; can become life threatening; also called a respiratory emergency. |
Chronic obstructive pulmonary disease | A progressive lung disease in which the patient has difficulty breathing because of damage to the lungs; airways become obstructed and the alveolar sacs lose their ability to fill with air. |
Crackles | An abnormal fine, crackling breath sound on inhalation that may be a sign of fluid in the lungs; also known as rales. |
Cricoid | A solid ring of cartilage just below and behind the thyroid cartilage. |
Cyanosis | A condition in which the patient’s skin, nail beds and mucous membranes appear a bluish or greyish color because of insufficient levels of oxygen in the blood. |
Deadspace | The areas within the respiratory system between the pharynx and the alveoli that contains a small amount of air that does not reach the alveoli. |
Emphysema | A chronic, degenerative lung disease in which there is damage to the alveoli. |
Finger sweep | A method of clearing the mouth of foreign material that presents a risk of blocking the airway or being aspirated into the lungs. |
Foreign body airway obstruction | The presence of foreign matter, such as food, that obstructs the airway. |
Hyperventilation | Rapid, deep or shallow breathing; usually caused by panic or anxiety. |
Hypoxia | A condition in which insufficient oxygen is delivered to the body’s cells. |
Jaw-thrust maneuver | A maneuver for opening the airway in a patient suspected of having an injury to the head, neck or spine. |
Midaxillary line | An imaginary line that passes vertically down the body starting at the axilla (armpit); used to locate one of the areas for listening to breath sounds. |
Midclavicular line | An imaginary line that passes through the midpoint of the clavicle (collarbone) on the ventral surface of the body; used to locate one of the areas for listening to breath sounds. |
Midscapular line | An imaginary line that passes through the midpoint of the scapula (shoulder blade) on the dorsal surface of the body; used to locate one of the areas for listening to breath sounds. |
Oxygenation | The addition of oxygen to the body; also, the treatment of a patient with oxygen. |
Paradoxical breathing | An abnormal type of breathing that can occur with chest injury; one area of the chest moves in the opposite direction to the rest of the chest. |
Pathophysiology | The study of the abnormal changes in mechanical, physical and biochemical functions caused by an injury or illness. |
Pneumonia | A lung infection caused by a virus or bacterium that results in a cough, fever and difficulty breathing. |
Positive pressure ventilation | An artificial means of forcing air or oxygen into the lungs of a person who has stopped breathing or has inadequate breathing. |
Pulmonary embolism | Sudden blockage of an artery in the lung; can be fatal. |
Rales | An abnormal breath sound; a popping, clicking, bubbling or rattling sound, also known as crackles. |
Respiratory failure | Condition in which the respiratory system fails in oxygenation and |
Resuscitation mask | A pliable, dome-shaped breathing device that fits over the mouth and nose; used to provide artificial ventilations and administer emergency oxygen. |
Rhonchi | An abnormal breath sound when breathing that can often be heard without a stethoscope; a snoring or coarse, dry rale sound. |
Stridor | An abnormal, high-pitched breath sound caused by a blockage in the throat or larynx; usually heard on inhalation. |
Suctioning | The process of removing foreign matter, such as blood, other liquids or food particles, by means of a mechanical or manual suctioning device. |
Tidal volume | The normal amount of air breathed at rest. |
Ventilation | The exchange of air between the lungs and the atmosphere; allows for an exchange of oxygen and carbon dioxide in the lungs. |
Wheezing | A high-pitched whistling sound heard during inhalation but heard most loudly on exhalation; an abnormal breath sound that can often be heard without a stethoscope. |
Airway adjunct | A mechanical device used to help keep the tongue from obstructing the airway; can be either nasal or oral. |
Nasopharyngeal airway | An airway adjunct inserted through the nostril and into the throat to help keep the tongue from obstructing the airway; may be used on a conscious or an unconscious patient. |
Oropharyngeal airway | An airway adjunct inserted through the mouth and into the throat to help keep the tongue from obstructing the airway; used only with unconscious patients. |
Emergency oxygen | Oxygen delivered to a patient from an oxygen cylinder through a delivery device; can be given to a nonbreathing or breathing patient who is not receiving adequate oxygen from the environment. |
Flowmeter | A device used to regulate, in liters per minute (LPM), the amount of oxygen administered to a patient. |
Hyperoxia | A condition in which an excess of oxygen reaches the body’s cells. |
Hypoxia | A condition in which insufficient oxygen reaches the body’s cells. |
Nasal cannula | A device used to administer emergency oxygen through the nostrils to a breathing person. |
Non-rebreather mask | A type of oxygen mask used to administer high concentrations of oxygen to a breathing person. |
O-ring gasket | Plastic ring that makes the seal of the pressure regulator on an oxygen cylinder tight; can be a built-in or an attachable piece. |
Oxygen cylinder | A steel or alloy cylinder that contains 100 percent oxygen under high pressure. |
Pressure regulator | A device on an oxygen cylinder that reduces the delivery pressure of the oxygen to a safe level. |
