FiO2 is...
|
Fraction of INSPIRED O2.
In other words...it is the concentration of O2 in the air we breathe. |
|
|
What is the Primary Function of the Cardiopulmonary System?
|
The primary function of the system is to deliver O2 and nutrients to the cells and remove waste products from the cells.
|
|
|
Tidal Volume
|
The Volume of Air moved in one cycle of breathing.
|
|
|
Minute Volume
|
The amount of air breathed in during each respiration multiplied by the number of breathes per minute.
|
|
|
Dead Air Space
|
Air that occupies the space between the mouth and the alveoli but that does not actually reach the area of gas exchange.
|
|
|
What section of the Brain is the seat of respiratory control?
|
The Medulla Oblongata
|
|
|
Hypercapnia
|
High concentrations of CO2 within the body.
|
|
|
Hypoxia
|
Low concentrations of O2 within the body.
|
|
|
Chemoreceptors
|
Chemical sensors in the brain and blood vessels that identify changing levels of o2 and CO2.
|
|
|
Plasma Oncotic Pressure
|
the pull exerted by the large Proteins in the Plasma portion of the blood that tends to pull water from the body into the bloodstream.
|
|
|
Hydrostatic pressure
|
The pressure within a blood vessel that tends to push water out of the vessel.
|
|
|
Network of arteries from Largest to Smallest
|
1. Artery
2. Arteriole 3. Vein 4. Venule 5. Capillaries |
|
|
Stretch Receptors
|
sensors in the blood vessels that identify internal pressure.
|
|
|
Stroke Volume
|
the amount of blood ejected from the Heart in one concetration.
|
|
|
Cardiac Output
|
the amount of blood ejected from the heart in one minute.
|
|
|
Preload is...
|
how much blood is returned to the heart prior to the contraction.
|
|
|
Contractility is...
|
the force of the concentration.
|
|
|
Afterload is...
|
a function of systemic vascular resistance.
|
|
|
How can Cardiac Output be impacted?
|
It could be impacted by the heart rates that are too fast (>180 in adults) limiting the filling of the heart and in fact decreasing stroke volume.
|
|
|
The Sympathetic Nervous System's "Fight-or-Fligth" response does what to the heart rate?
|
It increases heart rate and the strength of heart muscle contraction.
|
|
|
What does the Parasympathetic Nervous system help with?
|
it will slow the heart rate down and decrease contractility.
|
|
|
Mechanical Problems include:
|
Physical Trauma
Squeezing forces Loss of cardiac muscle function from cell death |
|
|
Electrical Problems typically occur when...
|
The diseases such as a heart attack or heart failure damage the electrical system of the heart.
|
|
|
The Water in the body is distributed into three spaces:
|
Intracellular Fluid(70%)
Intravascular Fluid(5%) Interstitial Fluid(25%) 60% of body weight is total body water. |
|
|
Edema is...
|
swelling associated with movement of water into the interstitial space.
|
|
|
Signs of Neurologic Impairment include:
|
Altered mental status
inability to speak or difficulty speaking visual or hearing disturbance inability to walk or difficulty walking paralysis weakness loss of sensation pupil changes |
|
|
GI bleeding can...
|
occur anywhere in the digestive tract from the esophagus to the anus.
It can be slow and chronic or can present with shock from acute massive bleeding in the form of rectal bleeding or vomiting blood. |
|
|
The MOST common digestive disorders are:
|
Vomiting and Diarrhea
|
|
|
Hypersensitivity
|
an exaggerated response by the immune system to a particular substance.
Also known as an Allergic Reaction. |
|
|
A severe allergic reaction is also known as...
|
An anaphylactic reaction.
