Chapter 9 Flashcards
When breathing completely stops
Respiratory arrest
The reduction of breathing to the point where oxygen intake is not sufficient to support life
Respiratory failure
A blue or gray color resulting from lack of oxygen in the body
Cyanosis
The passageway by which air enters or leaves the body
Airway
Increased work of breathing; a sensation of shortness of breath
Respiratory distress
Forcing air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing
Artificial ventilation
A device that uses oxygen under pressure to deliver artificial ventilation
Flow restricted, oxygen powered ventilation device
To device that provides positive pressure ventilation
Manual transport ventilate
I handheld device with a face mask and self refilling bag that can be squeezed to provide artificial ventilations to a patient
Bag valve mask
A permanent surgical opening in the Mac through which the patient breathes
Stoma
Device, usually with a one-way valve, to aid in artificial ventilation. It rescuer breathes through the valve when the mask is placed over the patients face.
Pocket facemask
A device connected to an oxygen cylinder to reduce cylinder pressure to a safe level for delivery of oxygen to a patient
Pressure regulator
Cylinder filled with oxygen under pressure
Oxygen cylinder
A valve that indicates the flow of oxygen in liters per minute
Flowmeter
And insufficiency of oxygen in the body’s tissues
Hypoxia
A device connected to the flow meter to add moisture to the dry oxygen coming from an oxygen cylinder
Humidifier
A face mask and reservoir bag device that delivers high concentrations of oxygen; The patient’s exhaled air escapes through a valve and is not rebreathed
Non-read breather mask
A device that delivers low concentrations of oxygen through two prongs that rest in the patients nostrils
Nasal cannula
A face mask and reservoir bag device that delivers a specific concentrations of oxygen by mixing oxygen with inhaled air
Venturi mask
To determine the signs of adequate breathing what five things should EMT do?
1) look for adequate and equal expansion
2) Listen for air entering and leaving
3) Feel for air moving in and out
4) check for typical skin coloration
5) note rate, rhythm, quality, and depth of breathing
When a patient is having an asthma attack on the respiratory system is trying to compensate what happens to the respiratory rate?
It increases
When the fight or flight responses stimulated, what happens to the blood vessels in the arms and legs?
They constrict
Why does the patient have wheezes when you start to listen with your stethoscope?
Air Force through narrow passageways you too bronchoconstriction
When the patient starts to get very anxious what is the likely cause
Hypoxia
When the asthmatic patient starts to get tired what is the potential result
Fatigued chest muscles
