|
|
Gag Reflex
|
vomiting or retching that results when something is placed in the back of the pharynx.
|
|
|
head tilt chin lift
|
tilting the head back so the chin lifts keeping the tongue from blocking the trachea. use when no head injury isn't suspected
|
|
|
humidifier
|
connects to the flow meter to add moisture to the dry oxygen to keep the patients nose from drying out

|
hyper-ventilate
|
to provide higher ventilation's then what is the normal rate.
|
|
|
hypoxia

|
|
Jaw thrust maneuver
|
correcting blockages of the airway by forcing the jaw forward with out tilting the head. use in patients suspected of having a spinal or head trauma
|
|
|
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 through two small prongs that rest on the patients nostrils
|
|
|
Nasopharyngeal airway
|
flexiable tube that is inserted through the nose into the pharynx to maintain an open airway.

|
oxygen cylinder
|
a cylinder that is filled with oxygen under pressure.
|
|
|
patent airway
|
airway that is open and clear and will remain that way with out interference
|
|
|
Pocket face mask
|
device usually with a one way valve to aid in artificial ventilation.
|
|
|
pressure regulator
|
device connected to an oxygen cylinder to reduce pressure to make the delivery to of oxygen to the patient safer
|
|
|
respiration
|
breathing
|
|
|
respiratory arrest
|
when breathing completely stops

|
|
respiratory distress
|
increased work of breathing a sensation of shortness of breath.

use of a vacuum device to remove blood, vomit, secretions or obstructions
|
|
|
Ventilation
|
breathing in of air or oxygen or providing breaths artificially
|
|
|
Venturi mask
|
face mask & reservoir mask bag device that delivers specific concentration of oxygen by mixing oxygen with inhaled air.
