Airway & Ventilation - Chapters 8-9 Flashcards
Forcing air or oxygen into the lungs when a patient has stopped (or has inadequate) breathing
Artificial ventilation
The amount of air that reaches the alveoli
Alveolar ventilation
A device that provides positive pressure ventilation, adjustable, portable, and easily carried on an ambulance
Automatic Transport Ventilator (ATV)
A handheld device with a face mask and self-refilling bag that can be squeezed to provide artificial ventilation store a patient from atmosphere or supply system
Bag-valve mask (BVM)
Exchange of oxygen and carbon dioxide between cells and circulating blood
Cellular respiration
Pressure applied to the cricoid right to minimize air entry into the esophagus during positive pressure ventilation
Cricoid pressure
A blue or gray color resulting from lack of oxygen
Cyanosis
A process by which molecules move from an area of high concentration to low concentration
Diffusion
A valve that indicates the flow of oxygen in liters per minute
Flow meter
A device that uses oxygen under pressure to deliver artificial ventilation. The trigger is placed where the rescuer can operate it while still using both hands to maintain a seal on the facemask. It has automatic flow restriction to prevent over delivery of oxygen to the patient
Flow-restricted, oxygen-powered ventilation device (FROPVD)
A device connected to the flow meter to add moisture to the dry oxygen coming from an oxygen cylinder
Humidifier
An insufficiency of oxygen in the body’s tissues
Hypoxia
A device that delivers low concentrations of oxygen through two prongs that rest in the patient’s nostrils
Nasal cannula
A facemask and reservoir bag device that delivers high concentrations of oxygen. The patients exhaled air escapes through a valve and is not rebreathed
Nonrebreather mask (NRB)
A cylinder filled with oxygen under pressure
Oxygen cylinder
A face mask and reservoir oxygen bag with no one-way valve to the reservoir bag so that some exhaled air mixes with the oxygen. Used to preserve carbon dioxide levels in the blood to stimulate breathing
Partial rebreather mask
A device with a one-way valve to aid in artificial ventilation. The rescuer breathes through the valve when the mask is placed over the patient’s face. It provides a barrier between patient’s breath and fluids.
Pocket face mask
Another term for artificial ventilation
Positive pressure ventilation
A device connected to an oxygen cylinder to reduce cylinder pressure so it is safe for delivery of oxygen to a patient
Pressure regulator
The exchange of oxygen and carbon dioxide between the alveoli and circulating blood in the pulmonary capillaries
Pulmonary respiration
The diffusion of oxygen and carbon dioxide between the alveoli and the blood and between the blood and the cells. Simplified to just mean “breathing.”
Respiration
When breathing completely stops
Respiratory arrest
Increased work of breathing; a sensation of shortness of breath
respiratory distress
The reduction of breathing to the point where oxygen intake is not sufficient to support life
Respiratory failure
A permanent surgical opening in the neck through which the patient breathes
Stoma
A device designed to be placed over a stoma or tracheostomy tube to provide supplemental oxygen
Tracheostomy mask
Breathing in and out
Ventilation
A face mask and reservoir bag device that delivers specific concentrations of oxygen by mixing oxygen with inhaled air
Venturi mask
