    • analgesia 
    • assist ventilations 
    • pt position 
    • para intervention

  18. how much o2 should you give in a maj trauma and by what mask?
    • 15 L per min
    • reservoir mask- non rebreather mask
  19. what two dressings options are there?
    • russell chest seal- sucking chest wound 
    • nightingale dressing
  20. when should you not used entanox with a chest wound?
    • pt risk of developing:
    • pneumathorax 
    • pneumomedastinum 
    • pneumoperitoneum
  21. what are 6 examples of chest injuries a pt could suffer?
    • pulmonary contusion
    • myocardial contusion 
    • aortic transection 
    • diaphragmatic injuries 
    • oesophageal injuries 
    • airways injuries
  22. with rib#, what should you be suspicious off?
    other injuries
  23. what ribs are most commonly #?
    4th- 9th
  24. what can rib # lead to?
    breathing shallow leading to inadequate ventilation
  25. how much blood loss can a  rib # lead to?
  26. what can a # rib cause?
    • damage to soft tissue (inc lung) 
    • leads to more serious injury
  27. what does a # sternum indicate?
    significant probability of other major injuries
  28. how many patients with a # sternum will die?
    • 1/4 
    • it is such a strong bone
    • force required to # it will cause other injuries
  29. what is a flail chest?
    2 or more ribs # in two or more places
  30. when does flail chest usually occur?
    blunt trauma
  31. what is a pneumothorax?
    air in the pleural space in the thoracic cavity
  32. what happens when more and more air enters the pleural space?
    put pressure on the lung causing it to collapse
  33. what will a pneumothorax cause eventually?
    • other structures to shift away from the pressure
    • e.g. trachea
  34. when a pneumothorax puts pressure on blood vessels returning to the heart, what does this cause?
    obstructive shock
  35. what is an open pneumothorax?
    • occurs from penetrating trauma 
    • hole allows air to enter pleural space
    • as pressures change each inspiration, air is drawn into pleural space- sucking chest wound
  36. what happens if the wound is large enough with an open pneumothorax?
    • air will preferentially enter through wound rather than via trachea
    • puts pt at even more risk of hypoxia
  37. what may you notice in an open pneumothorax?
    • bubbling wound 
    • if air is able to escape back out 
    • if air cannot escape then pneumothorax will grow
  38. what is the treatment priority with a open pneumothorax?
    • stop air being drawn in 
    • allow air to escape
  39. what is a tension pneumothorax?
    air enters the thoracic cavity (pleural space) and cannot escape
  40. in a tension pneumothorax, what will the pt increasingly become?
    • dyspnoeic 
    • tachy 
    • hypotensive
  41. what may you notice in the pt if they have tension pneumothorax?
    • reduced chest wall movement 
    • reduced breathing sounds 
    • distended neck veins 
    • tracheal deviation
  42. what is a haemothorax?
    blood in the thoracic (pleural cavity)
  43. what does a haemothorax usually occur from?
    • penetrating trauma injuring major blood vessels 
    • could be blunt deceleration shearing injury
  44. in a haemothorax, what happens when blood fills the thoracic cavity?
    • blood takes up the space normally occupied by the lungs and they collapse. 
    • pt has dual problem, hypoxia & hypovolaemia
  45. what is a cardiac tamponade?
    excessive fluid in pericardial sac compresses the heart limiting its ability to pump
  46. when is a cardiac tamponade more common?
    penetrating injury
  47. how much blood can cause a tamponade?
  48. what are the signs of cardiac tamponade?
    • MOI- penetrating wound 
    • clinical shock 
    • distending neck veins 
    • reduced LOC- soon cardiac arrest 
    • pt needs hems or trauma hospital for possible thoractomy
