Slow, gasping respiration, sometimes seen in dying patients.
agonal respirations
The upper airway tract or the passage above the larynx, which includes the nose, mouth, and throat.
A safety system for size D or larger oxygen cylinders, designed to prevent the accidental attachment of a regulator to a cylinder containing the wrong type of gas.
American Standard System
Absence of breathing.
The introduction of vomit or other foreign material into the lungs.
A device with face mask attached to a ventilation bag containing a reservoir and connected to oxygen; delivers more than 90% supplemental oxygen.
bag-valve-mask (BVM) device
A protective item, such as a pocket mask with a valve, that limits exposure to a patient's body fluids.
barrier device
A body part or condition that appears on both sides of the midline.
A hollow, cylindrical structure that drains or delivers fluids.
Occurs when a foreign body completely obstructs the patient's airway. Patients cannot breathe, talk, or cough.
complete airway obstruction
A technique that is used with intubation in which pressure is applied on either side of the cricoid cartilage to prevent gastric distention and allow better visualization of vocal cords; also called the Sellick maneuver.
cricoid pressure
A process in which molecules move from an area of higher concentration of molecules to an area of lower concentration.
The part of the breathing process in which the diaphragm and the intercostal muscles relax, forcing air out of the lungs.
A normal reflex mechanism that causes retching; activated by touching the soft palate or the back of the throat.
gag reflex
A condition in which air fills the stomach as a result of high volume and pressure during artificial ventilation.
gastric distention
A term used to distinguish the degree of distress in a patient with a partial airway obstruction. With good air exchange, the patient is still conscious and able to cough forcefully, although wheezing may be heard.
good air exchange
A combination of two movements to open the airway by tilting the forehead back and lifting the chin; used for nontrauma patients.
head tilt-chin lift maneuver
Backup system to control respirations when oxygen levels fall.
hypoxic drive
The active, muscular part of breathing that draws air into the airway and lungs.
A lack of oxygen that deprives tissues of necessary nutrients, resulting from partial or complete blockage of blood flow; potentially reversible since permanent injury has not yet occurred.
Technique to open the airway by placing the fingers behind the angle of the jaw and bringing the jaw forward; used when a patient may have a cervical spine injury.
jaw-thrust maneuver
Breathing that requires visibly increased effort; characterized by grunting, stridor, and use of accessory muscles.
labored breathing
The ability of the alveoli to fully expand when air is drawn in on inhalation.
lung compliance
The sum of all the physical and chemical processes of living organisms; the process by which energy is made available for the uses of the organism.
An oxygen delivery device in which oxygen flows through two small, tubelike prongs that fit into the patient's nostrils.
nasal cannula
Airway adjunct inserted into the nostril of a conscious patient who is not able to maintain a natural airway.
nasopharyngeal (nasal or trumpet) airway
A combination mask and reservoir bag system that is the preferred way to give oxygen in the prehospital setting; delivers up to 90% inspired oxygen.
nonrebreathing mask
Airway adjunct inserted into the mouth to keep the tongue from blocking the upper airway and to make suctioning the airway easier.
oropharyngeal (oral) airway
Condition in which an obstruction leaves the patient able to exchange some air, but also causes some degree of respiratory distress.
partial airway obstruction
A system established for portable cylinders to ensure that a regulator is not connected to a cylinder containing the wrong type of gas.
pin-indexing system
A partial or complete accumulation of air in the pleural space.
A term used to distinguish the degree of distress in a patient with a partial airway obstruction. With poor air exchange, the patient has a weak, ineffective cough, increased difficulty breathing, possible cyanosis, and may produce a high-pitched noise on
poor air exchange
An assessment method that measures oxygen saturation of hemoglobin in the capillary beds.
pulse oximetry
A position that helps to maintain a clear airway in a patient with a decreased level of consciousness who has not had traumatic injuries and is breathing on his or her own.
recovery position
Movements in which the skin pulls in around the ribs during inspiration.
A technique used with intubation, in which pressure is applied on either side of the cricoid cartilage to prevent gastric distention and allow better visualization of vocal cords; also called cricoid pressure.
Sellick maneuver
Opening in the neck that connects the trachea directly to the skin.
The amount of air that is delivered to the lungs and airways in one inhalation.
tidal volume
A large, semirigid suction tip recommended for suctioning the pharynx; also called a Yankauer tip.
tonsil tip
Exchange of air between the lungs and the air of the environment, either spontaneously by the patient or with assistance from an EMT-B.
