Cardiopulmonary Part Three Flashcards
how do PVCs look on EKG
no P wave
wide QRS (premature)
what is ventricular tachycardia
a run of three or more PVCs occurring sequentially
what is intermittent claudication
pain, cramping, and lower extremity fatigue occurring during exercise and relieved by rest
pitting edema AKA
indentation
what is orthopnea
inability to breathe when in reclining or supine position
normal values of pulse oximetry
95-100%
what do ventricle arrhythmias form form
ectopic focus in the ventricles
what is to be expected with skin temperature with poor arterial perfusion
decreased skin temperature
what do nitrates do to heart rate
increases heart rate
when does the ST segment become depressed
impaired coronary perfusion (ischemia or injury)
CHF: symmetrical or assymetrical edema
bilateral
what is bradypnea
decrease of RR under 10 breaths per minute
what can crackles indicate
secretions in the lungs
what is non-sustained ventricular tachycardia (NSVT)
3 or more consecutive beats in duration, terminating spontaneously in less than 30 seconds
what is dyspnea
shortness of breathe
what is rubor
dependent redness with PAD
what are premature ventricular contractions
premature beat resulting from the ventricle
where is pain typically for IC
mostly the calves
but can be in the thigh, hips, or buttocks
BPM of:
atrial tachycardia
atrial flutter
fibrillation
AT: 140-250
AF: 250-350
fibrillation: over 300
what is orthostatic hypotension
drop in BP that accompanies change from supine to standing
