|
how do you confirm placement of ET Tube
|
continuous quatitative waveforme capnography
- it displays the partial pressure of CO2 |
|
|
why must you avoid hyperventilation and what are the effects?
|
giving too many breaths or too large a volume can be harmful because it increases intrathoracic pressure, decreased venous return to the heart and diminishes cardiac output
|
|
|
Oxygen devices and flow rates:
percentage oxygen delivered: nasal cannula |
1-6 L/min
21-44% O2 delivered |
|
|
Oxygen devices and flow rates:
percentage oxygen delivered: venturi mask |
4-12 L/min
24-50% O2 delivered |
|
|
Oxygen devices and flow rates:
percentage oxygen delivered: partial rebreather mask |
6-10 L/min
35-60% O2 delivered |
|
|
Oxygen devices and flow rates:
percentage oxygen delivered: nonrebreather O2 mask |
6-15 L/min
60-100% O2 delivered |
|
|
Oxygen devices and flow rates:
percentage oxygen delivered: bag mask with nonrebreather tail |
15 L/min
95-100% O2 delivered |
|
|
what are the 2 shockable rhythms?
|
pulsless VT
VF (this deteriorates to asystole if not treated) |
|
|
TRUE or FALSE?
the presence of an implantable defribrillator is a contraindication to using an AED |
FALSE- you can use it, just don't place the pads right over the device
|
|
|
drugs for VF/VT
|
epinephrine
vasopressin lidocaine amiodarone magnesium (if torsades present) |
|
|
VF/VT algorithm
(after BLS primary survey and initial ABCs and O2) |
Give 1 shock
- bipahsic 120J-200J - monophasic 360J Resume CPR- 5 cycles (2 min) Check rhythm give another shock (if needed) Resume CPR immediately give epinephrine 1mg IV/IO - repeat every 3-5 min - can use vasopressin 40U to replace 1st or second dose of epi Resume CPR- 5 cycles Check rhythm give 1 shock Resume CPR cosider antiarrythmics - amiodarone 300mg once (then 150mg additional) OR - lidocaine 1-1.5 mg 1st dose then 0.5-0.75; max 3 doses |
|
|
asystole/ pulseless arrest algorithm- not shockable rhythm
|
CPR- 5 cycles
Give epi 1mg every 3-5 min or vasopressin 40U CPR- 5 cycles Check rhythm rinse and repeat if rhythm remains unshockable no antiarrhythmics needed since PEA is not an arrhythmia |
|
|
when should you conduct a rhythm check?
|
after every 5 cycles of CPR
1 cycle = 30 compressions, 2 ventilations |
|
|
when and how do you give magnesium?
|
Magnesium is for torsades de pointes
loading dose 1-2g IV/IO diluted in 10ml D5W |
|
|
how does the VF/VT algorithm differ in a patient with hypothermia?
|
a single defibrillation attempt is appropriate
- hypothermic heart may be unresponsive to drug therapy so defer admin of drugs until core temperature rises above 86 |
|
|
what are the 3 routes of access for drugs?
|
IV
IO thru ET tube |
|
|
what's important to remember about administering drugs via the ET route?
|
you have to give 2 to 2.5 times the IV dose
|
|
|
which drugs can be administered via the ET route?
how do you give it? |
epinephrine
vasopressin atropine lidocaine naloxone dilute the dose in 5-10ml of water or NS |
|
|
with the bag-valve device, what is the preferred tidal volume that needs to be given with ventilating a patient?
|
10-15 ml/kg
|
|
|
what's the potential complication of the bag-valve mask device
|
pneumothorax if you infalte too hard
|
