Front Back
airway
the passageway by which air enters or leaves the body. The structures of the airway are the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs (patent artificial airway)
artificial ventilation
forcingg air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing. Also called positive pressure ventilation
automatic transport ventilator (ATV)
a device that provides positive pressure ventilations. It includes settings designed to adjust ventilation rate and volume, is portable, and is easily carried on an ambulance
bag-valve mask (BVM)
a handheld device with a face mask and self-refilling bag that can be squeezed to provide artificial ventilations to a patient. It can deliver air from the atmosphere or oxygen from a supplemental oxygen supply system
cyanosis
a blue or gray color resulting from lack of oxygen to the body
dead space
areas of the lungs outside the alveoli where gas exchange with the blood does not take place
flowmeter
a valve that indicates the flow of oxygen in liters per minute
flow-restricted, oxygen-powered ventilation device (FROPVD)
a device that uses oxygen under pressure to deliver artificial ventilations. Its trigger is placed so that the rescuer can operate it while still using both hands to maintain a seal on the face mask. It has automatic flow restriction to prevent overdelivery of oxygen to the patient
gag reflex
vomiting or retching that results when something is placed in the back of the pharynx. This is tied to the swallow reflex
head-tilt, chin-lift maneuver
a means of conrrecting blockage of the airway by the tonguee by tilting the head back and lifting the chin. Used when no trauma or injury is suspected
humidifier
a device connected to the flowmeter to add moisture to the dry oxygen coming from an oxygen cylinder
hyperventilate
to provide ventilations at a higher rate than normal
hypoxia
an insufficiency of oxygen to the body's tissues
jaw-thrust maneuver
a means of correcting blockage of the airway by moving the jaw forward without tilting the head or neck. Used when trauma, or injury, is suspected to open the airway without causing further injury to the spinal cord in the neck
minute volume
the amount of air breathed in during each respiration multiplied by the number of breaths per minute
nasal cannula
a device that delivers low concentrations of oxygen though two prongs that rest in the patient's nostrils
nasopharyngeal airway
a flexible breathing tube inserted through the patient's nose into the pharynx to help maintain an open airway
nonrebreather mask
a force mask and reservoir bag device that delivers high concentrations of oxygen. The patient's exhaled air escapes through a valve and is not rebreathed
oropharyngeal airway
a curved device inserted through the patient's mouth into the pharynx to help maintain an open airway
oxygen cylinder
a cylinder filled with oxygen under pressure
patent airway
an airway (passage from nose or mouth to lungs) that is open and clear and will remain open and clear, without interference to the passage of air into and out of the body
pocket face mask
a device, usually with a one-way valve, to aid in artificial ventilation. A rescuer breathes through the valve when the mask is placed over the patient's face. It also acts as a barrier to prevent contact with a patient's breath or body fluids. It can be used with supplemental oxygen when fitted with an oxygen inlet
positive pressure ventilation
see artifical ventilation
pressure regulator
a device connected to an oxygen cylinder to reduce cylinder pressure so it is sade for dewlivery of oxygen to a patient
respiration
breathing
respiratory arrest
when breathing completely stops
respitatory distress
increased work of breathing; a sensation of shortness of breath
respiratory failure
the reduction of breathing to the point where oxygen intake is not sufficient to support life
stoma
a permanenet surgical opening in the neck through which the patient breathes
suctioning
use of a vacuum device to remove blood, vomitus, and otehr secretions or foreign materials from the airway
ventilation
the breathing in of air or oxygen ot providing breaths artificially
venturi mask
a face mask and reservoir bag device that delivers specific concentrations or oxygen by mixinf oxygen with inhaled air
