ANSWERS WITH COMPLETE SOLUTIONS GRADED A++
EMR medical legal responsibilities
- above all else, do no harm
- provide all your care in good faith
- provide proper consistent care, be compassionate, and maintain your composure
each state may have specific laws
Duty to Act
if you are employed as an EMR and are dispatched you MUST proceed promptly to the
scene and render emergency medical care within the limit of your training and available
equipment
Standard of Care
- you must treat the patient to the best of your ability
- you must provide care that a reasonable, prudent person with similar training would
provide under similar circumstances
expressed consent
patient actually lets you know (verbally or non-verbally) that they are willing to accept
treatment
patient must be of legal age and able to make a rational decision
implied consent
the patient does not specifically refuse emergency care
,refusal of care
patients must be informed of the consequences of refusing care and why the treatment
might be needed
carotid pulse point
- 60 mmHg systolic pressure minimum
femoral pulse point
- 70 mmHg SP min
- most common pulse point in emergency medicine
radial pulse point
- 80 mmHg SP min
-anterior lateral arm
pedal pulse point
- 90-100 mmHg SP min
AVPU
Alert - patients eyes are open
Voice - patient responds to verbal stimuli
Pain - Patient responds to painful stimuli
Unconscious - patient does not respond to any measure
Tidal Volume
amount of air moved into and out of the lungs during a breath
Dead space
amount of air that remains in the non-gas exchange areas of the lungs
minute ventilation
, Vt (tidal volume) x RR (respiratory rate)
alveolar minute ventilation
(Vt - Vd) X RR
- Vd = dead space, ~150
PEEP
peak end expiratory pressure
keeps alveoli open
FiO2
percent of O2 being delivered
Head tilt-chin lift
-opens patient airway
-one hand on forehead and apply firm pressure backward
tips of fingers under bony part of lower jaw, tilt chin forward
Jaw thrust
-opens patient airway of you suspect a neck injury
-fingers on lower jaw and move jaw forward
tilt head into a neutral position
Opening an airway
-preform airway maneuver
- clear possible obstructions
- airway adjuncts
