Across

2. device a device that uses oxygen under pressure to deliver artificial ventilations. its trigger is placed so the rescuer can operate it while still using both hands to maintain a seal on the face mask. it has automatic flow restriction to prevent overdelivers of oxygen to the patient.
6. a device that provides positive pressure ventilations. it includes settings designed to adjust ventilation rate and volume, is portable and is easily carried on an ambulance.
10. awareness that there may be injuries.
11. high pitched sound generated from partially obstructed airflow in upper airway.
12. 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 system.
13. a process by which molecules move from an area of high concentration to an area of low concentration.
15. the diffusion of oxygen and carbon dioxide between the alveoli and the blood and between the blood and the cells.
17. a cylinder filled with oxygen under pressure.
19. a blue or gray color resulting from lack of oxygen in the body.
20. the amount of air that reaches the alveoli.
22. impressions of the patients condition that is formed on the first approaching the patient, based not eh patients environment, chief complain and appearance.
23. what is medically wrong with the patient.
24. use of a vacuum device to remove blood, vomitus and other secretions or foreign materials from the airway.
28. breathing in and out, or artificial provision of breaths.
29. the reduction of breathing to the point where oxygen intake is not sufficient to support life.
35. curved device inserted through the patients mouth into the pharynx to help maintain open airway.
38. increased work of breathing; a sensation of shortness of breath.
41. in emergency medicine the reason Ems was called, usually in the patients own words.
44. airway that is open and clear and will remain open and clear without interference to the passage of air into and out of the body. this includes from nose or mouth to lungs.
45. injury caused by a blow that does not penetrate the skin or other body tissues.
46. a device connected to an oxygen cylinder to reduce cylinder pressure so it is safe for delivery of oxygen to a patient.
47. the exchange of oxygen and carbon dioxide between cells and circulating blood.
48. means of correcting blockage of the airway by moving the jaw forward without tilting head or neck.
49. means of correcting blockage of the airway by the tongue by tilting head back and lifting the chin.
50. flexible breathing tube inserted through the patients nostril into the pharynx to help maintain an open airway.
51. a device designed to be placed over a stoma or tracheostomy tube to provide supplemental oxygen.

Down

1. 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 patients face. it also acts as a barrier to prevent contact with a patients breath or body fluids. it can be used with supplemental oxygen when fitted with an oxygen inlet.
3. a memory aid for classifying a patients level of responsiveness or mental status.
4. Contraction of smooth muscle that lines the bronchial passages that results in a decreased internal diameter of the airway and increased resistance to airflow.
5. actions taken to correct or manage a patients problems.
7. airway, breathing, and circulation
8. forcing air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing.
9. when breathing completely stops.
14. a permanent surgical opening in the neck through which the patient breathes.
16. a valve that indicates the flow of oxygen in liters per minute.
18. a force or forces that may have caused injury.
21. the exchange of oxygen and carbon dioxide between the alveoli and circulating blood in the pulmonary capillaries.
25. the first element in a patient assessment; steps taken for the purpose of discovering and dealing with any life-threatening problems. the 6 parts include: forming a general impression, assessing mental status, assessing airway, assessing breathing, assessing circulation, determining priority of patient for treatment and transport to hospital.
26. a face mask reservoir bag device that delivers high concentrations of oxygen. the patients exhaled air escapes through a valve and is not rebreathed.
27. mask a face mask and reservoir oxygen bag with no one - way valve to the reservoir bag so some exhaled air mixes with the oxygen; used in some patients to help preserve carbon dioxide levels in the blood to stimulate breathing.
30. the area around the wreckage of a vehicle collision or other incident within which special safety precautions should be taken.
31. the decision regarding the need for immediate transport of the patient versus further assessment and care at the scene.
32. Passageway by which air enters and leaves the body. Structures include nose, mouth, pharynx larynx, trachea, bronchi, and lungs.
33. a face mask and reservoir bag device that delivers specific concentrations of oxygen by mixing oxygen with inhaled air.
34. an insufficiency of oxygen in the body tissues.
36. injury caused by an object that passes through the skin or other body tissues.
37. steps taken when approaching the scene of an emergency call; checking scene safety, taking standard precautions, noting the mechanism of injury or nature of the patients illness, determining number of patients, and deciding what if any additional resources to call for.
39. a device connected to the flowmeter to add moisture to the dry oxygen coming from an oxygen cylinder.
40. Reflex Vomiting or retching that results when something is placed in the back of the pharynx. tied to swallow reflex.
42. a device that delivers low concentrations of oxygen through two prongs that rest in the patients nostrils.
43. level of responsiveness
