Section 4 Flashcards
generally the most reliable and accessible pulse site
Carotid artery
safest method for opening the airway if there is the possibility of cervical spine injury
Jaw thrust
most common cause of death in resuscitated patients
Anoxic brain injury
most effective modality for return of spontaneous circulation (ROSC)
Early defibrillation
phase of cardiac arrest, present in the first 5 minutes of arrest, where the cardiac system is most amenable to defibrillation if a shockable rhythm is present
Electrical phase
phase of cardiac arrest when high-quality chest compressions and epinephrine provide the greatest benefit
Circulatory phase
most reliable means of confirming and continuously monitoring tracheal tube placement, as well as monitoring resuscitation and ROSC
Waveform capnography
most common adverse reaction of epinephrine
tachycardia
most common unwanted effects of amiodarone
Hypotension and bradycardia
greatest risk for non-obstetric cause of death
major trauma
most common cause of septic shock in pregnancy
Pyelonephritis
most common use of NIPPV
cardiogenic pulmonary edema
best method for confirming successful intratracheal placement
directly visualizing the tube between the vocal cords
most commonly used agent for neuromuscular blockade in ED RSI.
Succinylcholine
primary indication for surgical airway placement
cannot intubate–cannot oxygenate scenario
preferred primary modality in patients with extensive airway injuries
Surgical airway
most commonly accessed veins for peripheral catheterization of the upper extremity
dorsal hand and the antecubital fossa
most accessible central access site during critical illness
Femoral vein
Most common site for arterial line placement
radial artery
most important driving force determining regional blood flow, which in the aggregate defines CO.
Perfusion pressure
ideal indicator of perfusion and oxygen delivery
Cardiac Output
Most common pacemakers
VVI and DDD
most common Pacemaker complication in the setting of VVI
Atrioventricular synchrony and the presence of ventriculoatrial conduction
most common complication after pacemaker insertion
Pacemaker syndrome
Most common cause of death in patients with an implantable cardioverter-defibrillators
congestive heart failure
Most common reason a patient with an implantable cardioverter-defibrillator comes to the ED
evaluation after a delivered shock.
Most characteristic sign on echocardiogram in pericardial tamponade
right-sided heart collapse
largest group with pericardial effusions leading to hemodynamic compromise
Oncology patients
Most common indication for pericardiocentesis
clinical tamponade (83%), with echocardiographic findings of ventricular diastolic collapse (69%) and right atrial collapse (33%).
most common approach to pericardiocentesis
left parasternal approach or the apical approach
In blunt facial trauma, the principal cause of death is
airway obstruction from bleeding (often from fractures) or soft tissue swelling
