unconsciousness Flashcards
analgestic means?
acting to relieve pain
first thing to do if person is unconscious?
supine position
brain damage occurs how fast without oxygen? cardiac arrest?
brain damage within 4-6 minutes
cardiac arrest within 5-10 minutes
what are pathophysiology mechanisms that cause unconsciousness?
1) reduced cerebral metabolism from inadequate delivery of blood or oxygen to brain= SUPINE POSITION
2) metabolic deficiencies that decrease the quality of blood perfusion– supine position will not help
3) direct or reflex effects on areas of CNS that regulate consciousness
4) psychic
3 criteria for lack of consciousness
1) lack of response to stimulation (shouting or tappin)
2) loss of protective reflexes
3) inability to maintain a patent airway
supine position
head and heart are at the same level and feet slightly elevated
why place a pillow under the hip of prego woman?
to prevent gravid uterus obstructing inferior vena cava
scenario of patient breathing but remains unconscious
maintain open airway and proceed with additional management
scenario with no respirations and no chest movement
begin artificial ventilation
scenario with respiration but chest/abdominal movements or minimal air movement with noisy air flow
assume obstruction and reattempt to open airway/reassess
rates of rescue breathing for adults vs children?
adult= every 5 seconds
children= every 3 seconds
gastric distension?
a serious complecation during ventilation that causes increased risk of regurgitation and limits movement of diaphragm
**caused by overinflation of obstruction
what are the 3 ways to give oxygen enriched ventilation?
1) demand-valve mask on portable E cylinder (doesn’t like)
2) inhalation -sedation unit
3) bag-valve-mask with attached oxygen source
what is the number 1 reported medical emergency in dental offices?
vasodepressor syncope
vasodepressor syncope is common in?
young MEN
