suggest?
Intermediate risk for OSA
What does answering yes to 5+ questions on the STOP BANG questionnaire
suggest?
High risk of OSA
What is Sundowning?
When elderly patients get confused in the early evening
What is an important factor to consider when dealing with a patient with PTSD
Ask how is the best way to wake them up during the night if needed
What is the role of the sympathetic nervous system
fight or flight
what is the role of the parasympathetic nervous system
controls smooth muscle
,What is the pacemaker for circadian rhythm in the brain
suprachiasmatic nucleus
What effect on sleep does a decrease in dopamine have?
decrease sleep
If the distance between 2 R waves is between 3-5 large blocks, the rate is ______
Normal
If the distance between 2 R waves is less than 3-5 large blocks, the rate is ______
greater than 90bpm (tachycardia)
If the distance between 2 R waves is greater than 3-5 large blocks, the rate is
______
less than 60bpm (bradycardia)
What is the formula for estimating HR on ECG
300/(# of large blocks btwn R waves)
What are the causes and treatment of sinus tach
hypoxemia, pain, stress
oxygen
What are common causes and treatment of sinus brady
blood loss, infection of heart, OSA
treat underlying cause
What are common treatments for PVCs
oxygen, lidocaine
What is bigeminy
PVC every other beat
Trigeminy
PVC every 3rd beat
Couplet
2 PVCs in a row
What is the treatment for VTach with a pulse
cardioversion
What is the treatment for VTach without a pulse
defibrillation
, Cardiac ischemia is indicated by
depressed t waves
Cardiac injury is indicated by
elevated ST segment
What can cause inverted t waves
digitalis toxicity and hypokalemia
What causes spiked t waves
hyperkalemia
This rhythm creates a series of identical p waves that take on a sawtooth
appearance.
Atrial flutter
This rhythm occurs when multiple ectopic foci are firing almost continuously and
produces an irregular baseline with no visible p waves and irregular QRS
complexes
Atrial fibrillation
Cardiac infarction is diagnosed by
significant q waves
Which heart block is identified by prolonged P-R interval?
1st degree AV block
Which heart block is characterized by increasingly longer PR intervals until a
missing QRS
2nd degree AV block Mobitz 1 (Wenchebach)
longer, longer, longer, drop, then you got a wenchebach
Which heart block is characterized by missing QRS
2nd degree AV block Mobitz II
If some P's don't get through, you have a mobitz type 2
Which Heart block is characterized by an atrial rate greater than 60, and a
ventricular rate less than 40? The PR interval cannot be determined and the QRS
is widened
3rd degree AV block
If P's & Q's dont agree, then you have a 3rd degree
