Emergency Care 13th Edition Chapter 10 Flashcards

2681793753	alveolar ventilation	the amount of air that reaches the alveoli	0
2681796349	artificial ventilation	forcing air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing. Also called positive pressure ventilation	1
2681800293	bag-valve mask	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	2
2681808633	cellular respiration	the exchange of oxygen and carbon dioxide between cells and circulating blood	3
2681811655	cyanosis	a blue or grey color resulting from the lack of oxygen in the body	4
2681815603	diffusion	a process by which molecules move from an area of high concentration to an area of low concentration	5
2681819665	flowmeter	a valve that indicates the flow of oxygen in liters per minute	6
2681822598	flow-restricted, oxygen-powered ventilation device	a device that uses oxygen under pressure to developer artificial ventilation. its a trigger is placed so the rescuer can operate it while still using both hands to maintain a seal on the face. it has a automatic flow restriction to prevent over delivery of oxygen to the patient.	7
2681835367	humidifier	a device connected to the flowmeter to add mositure to the dry oxyfen coming from an oxygen cylinder	8
2681837885	hypoxia	an insufficiency of oxygen in the body's tissue	9
2681839774	nasal cannula	a device that delivers low concentrations of oxygen through the two prongs that test in the patient's nostrils	10
2681842046	nonrebreather mask	a facemask and reservoir bag device that delivers high concentrations of oxygen, The patient's exhaled air escapes through a valve and is not rebreathed.	11
2681845151	oxygen cylinder	a cylinder filed with oxygen under pressure	12
2681847806	partial nonrebreather mask	a face mask and a reservoir oxygen bag with no one-way valve to the reservoir bag so some exhaled air mizes with the oxygen; not commonly used in the EMS pre-hospital setting	13
2681852570	pocket 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 fluid. it can be used with supplemental oxygen when fitted with an oxygen inlet.	14
2681887860	positive pressure ventilation	see artificial ventilation	15
2681888949	pressure regulator	a device connected to an oxygen cylinder to reduce cylinder pressure so it is safe for delivery of oxygen to a patient	16
2681893849	pulmonary respiration	the exchange of oxygen and carbon dioxide between the alveoli and circulation blood in the pulmonary capillaries	17
2681897761	respiration	the diffusion of oxygen and carbon dioxide between the alveoli and the blood and between the blood and the cells. also used to mean, simply, breathing	18
2681900498	respiratory arrest	when breathing completely stops	19
2681901398	respiratory distress	increased work of breathing; a sensation of shortness of breath	20
2681902255	respiratory failure	the reduction of breathing to the point where oxygen intake is not sufficient to support life	21
2681903719	stoma	a permanent surgical opening in the neck through which the patient breathes	22
2681906357	tracheostomy mask	a device designed to be placed over a stoma or tracheotomy tube to provide supplemental oxygen	23
2681908081	ventilation	breathing in and out or artificial provisions of breaths	24
2681909222	venturi mask	a face mask and reservoir bag device that deliver specific concentrations of oxygen by oxygen with inhaled air.	25
