Chapter 11 Flashcards
Aerobic Metabolism
Metabolism that can only proceed in the presence of oxygen
Aerosol generating procedure
Any airway manipulation that induces the production of aerosols that may present a risk for airborne transmission of pathogens, such as CPR.
Agonal gasps
Abnormal breathing pattern characterized by slow, gasping breaths, sometimes seen in patients in cardiac arrest.
airway
The upper airway tract or the passage above the larynx, which includes the nose, mouth, and throat.
alveolar minute volume
The volume of air moved through the lungs in 1 minute minus the dead space; calculated by multiplying tidal volume (minus dead space) and respiratory rate.
alveolar ventilation
The volume of air that reaches the alveoli. It is determined by subtracting the amount of dead space air from the tidal rolume.
American standard safety system
A safety sys-m for large oxygen cylinders, designed to pre-nt the accidental attachment of a regulator to a inder containing the wrong type of gas.
anaerobic metabolism
The metabolism that as place in the absence of oxygen; the main roduct is lactic acid.
apnea
absence of spontaneous breathing
apneic oxygenation
A technique in which oxygen administered via a high-flow nasal cannula is ler. in place during an intubation attempt, allowing
‘or continuous oxygen delivery into the airways during all phases of the procedure.
aspiration
In the context of the alway, the intro. auction of vomitus or other foreign material into the lungs.
ataxic respiration
Irregular, ineffective respira. tions that may or may not have an identifiable
pattern.
Automatic transport ventilator (ATV)
A ventilation device attached to a control box that allows the variables of ventilation to be set. It frees the EMT to perform other tasks while the patient is being ventilated.
Bag mask device
A device with a one-way valve and a face mask attached to a ventilation bag; when attached to a reservoir and connected to oxygen, it delivers more than 90% supplemental oxygen.
barrier device
A protective item, such as a pocket mask with a valve, that limits exposure to a patient’s body fluids.
