parameters that tell you oxygenation is adequate

oxygenated inspired air is best provided via a tight fitting oxygen reservoir face mask with a flow rate of at least 11 L/min

pulse oximetry must be used at all times

doesn’t measue PaO2
measured saturation >95% by pulse oximetry is strong coroborating evidence of adequate peripheral arterial oxygenation (PaO2 >70mmHg)
limited usefulness in pt with severe vasoconstriction & carbon monoxide poisoning because it can’t distinguis oxyhemoglobin from carboxyhemoglobin or methemoglobin
profound anemia (hb <5g/dl) and hypothermia (<30ºC or <86ºF) decrease the reliability of the technique

how can you tell that the ET tube is in the right place

hearing equal breathing sounds bilaterally and detecting no borboygmi in epigastrium

the presence of CO2 in exhaled air indicates that airway has been successfully intubated, but doesn’t ensure the correct position of the tube

proper position of the tube is confirmed by chest X-ray

what are some AED keypoints

assure O2 isn’t following across the pts chess when delivering
don’t stop chest compressions for more than 10 sec. when assessing the rhythm
STAY CLEAR
asses pulse after the 1st 2 min of CPR
if the en tidal CO2 is <10mmHg during CPR, consider adding a vasopressor and improve chest compressions

key components of post cardiac arrest care

therapeutic hypothermia (32 - 36ºC) 
- recommended for commatose individuals with return of spontaneous ciculation after a cardiac arrest event

optomization of hemodynamias and ventilation

100% O2 is acceptable for early intervention but not for extended periods of time
oxygen should be titrated, so that the pulse oximeter >94%
don’t over ventilate
ventilation rates of 10 - 12 breaths x min to achieve ETCO2 at 35 - 40mmHg
IV fluids and vasoactive meds should be titrated for hemodyamic stability

Percutaneous Coronary Intevention (PCI):
- preferred over thrombolytics

Neurologic Care:

neurologic assessment is key
specialty consultation should be obtained to monitor neurologic signs and symptoms throughout the post resuscitation period

characteristics of a sinus bradycardia

Study These Flashcards

regular
rate generally 40 - <60bpm
PR interval 0.12-0.20 sec, consistent
QRS complex <0.12 sec

characteristics of a 1ºblock

Study These Flashcards

regular
rate depends on underlying rhythm
p wave >0.20sec, consistent
QRS complex <0.12sec

characteristics of a type I 2ºblock (weckenbach)

Study These Flashcards

rhythm isn’t regular but does have a pattern to it, R-R interval gets longer a PR intervals get longer
ventricular rate is usually slightly higher than the atrial rate due to some atrial beats no being conducted
the atrial rate is usually normal
P wave upright and uniform, doesn’t always proceed a QRS complex
PR interval gets progressively longer until there is a dropped QRS complex
QRS complex <0.12sec

characteristics of a type II 2º block

the regularity depends if there is or isn't a conduction ratio atrial rate is normal ventricular rate usually slower than atrial rate P wave upright and uniform, a QRS doesn't always follow every p wave ***there is a conduction ratio (a QRS drops after "X" amount of p waves) PR interval is constant across the strip, but not every P conducts a QRS*** QRS complex <0.12 sec

characteristics of a 3º block

***R-R regular, P-P wave regular but independent*** atrial rate regular and normally 60 - 100bpm rate of QRS complex is dependent on the focus - ventricular focus: 20 - 40 bpm - junctional focus: 40 - 60 bpm p wave upright and regular there isn't a QRS following every p wave PR interval may or may not be longer that normal QRS complex usually prolonged

what are the rules for atrial fibrilation / irregular narrow complex tachycardia

***R-R irregular*** atrial rate usually >350 if ventricular rate is 60-100 = controlled A-fib if ventricular rate is >100= uncontrolled A-fib ***there are no obvious P waves in the rhythm**** QRS complex normal
