What is the function of valves in the heart?
To prevent the backflow of blood
When you listen to a normal heart beat through a stethoscope what sound does it make, and what causes this sound?

What are the symptoms of left sided CHF?
Shortness of breath and wakes up in the middle of the night gasping for air
What is the normal treatment for CHF?
Diuretics; so the patient pees out the excess fluid
How is the cardiovascular system monitored?
By using tone pulse, blood pressure and the EKG
What is the autonomic nervous system responsible for?
for controlling the bodily functions not consciously directed
Causing increased heart rate and blood pressure and bronchodilates the airways; "Fight or flight"
Sympathetic nervous system
Results in stimulation of salivary glands, and slows the heart rate; "couch potatoes state"
Parasympathetic nervous system
Another name for stroke
Cerebral vascular accident
A type of Cerebral vascular accident where a blood clot occurs in the brain causing the blood vessel to become occluded depriving the brain tissue of oxygen
embolic stroke
A type Cerebral vascular accident where a bold vessel ruptures and bleeds depriving the brain tissue of oxygen
Hemorrhagic stroke
Symptoms of a cerebral vascular accident include:
Weakness of extremities usually one side only
Facial palsy or slurred speech
headache
How is the cardiovascular system monitored?
By the patients pulse rate, the patients blood pressure and the EKG
What 3 areas are the most common to take a pulse?
Radial, Branchial and carotid
What is the ideal size for a blood pressure cuff to ensure an accurate BP reading?
Greater that 1/3 the circumference of the arm
What does systolic pressure represent?
The force of the ventricular contraction
The sound of the blood rushing through the veins after the BP cuff releases?
Korotkoff sounds
What is the autonomic nervous system?
Responsible for control of the bodily functions not consciously
What are the components of the autonomic nervous system?
Sympathetic and parasympathetic
What reaction does the sympathetic nervous system induce?
"Fight o flight"; increased heart rat and BP, bronchodilates airways
What reaction does the parasympathetic nervous system induce?
"Couch potato, vegetation state"; stimulation of the salavery glands, and slows heart rate
Another name for stroke
Cerebral vascular accident (CVA)
What are the two types of strokes?
Embolic and hemorrhagic
What is an embolic stroke?
Where a blood clot causes a blood vessel to become occluded depriving the brain of oxygen
What is a hemorrhagic stroke?
Where a blood vessel rapture and bleeds depriving the brain of oxygen
What are symptoms of a stroke
-weak extremities (usually one side)
-facial palsy
-slurred speech
What treatment is recommended for an embolic stroke?
Thrombolytic agents (clot busters)
What is long term prevention for stoke?
Anticoagulants (like Coumadin)
Risk factors for a stroke:
Diabetes
Hyperstension
Smoking
High cholesterol
Arterial fibrillation
What is diabetes?
Disease of insufficient insulin secretion
What is the function of insulin?
To break down the sugar and put it into storage form
The hormone that brings insulin out of storage
Glucagon
How are patients effected by GA procedures?
-pts cannot eat or drink for several ours
-normally will not eat a solid meal after surgery
How will you treat a patient that is diabetic for a GA case?
Insulin doses will be decreased the morning of surgery due to lack of food intake
