test 7,9,10 Flashcards
Whats the space between the base of the tongue & epiglottis
vallecula
what is normal breathing per minute for a child?
15-30 per min
Infant normal Breathing per minute?
25-50 per min
Two examples of ventilation and perfusion mismatch
Pulmonary embolus
an Acute asthma attack
What is ATP
Define it..
( Adenosine Triphosphate)
It’s the energy for a cell
The oxygen concentration of inspired air is?
21%
what is the formula to determine cardiac output
Multiply heart rate * stroke volume
Two substances brought into the body that are required to create ATP in the cell?
Glucose & Oxygen
What is JVD?
Define:
Jugular Venous Distention
Indicates an excess pressure in the chest. or problems with the heart
Respiratory Arrest
When breathing completely stops
infection of protective layer of brain & spinal cord
meningitis
Too much water does what to a cell?
it interrupts basic cellular function
Cells produce energy MOST efficiently from
Aerobic metabolism
hypovolemia (low blood volume) occurs when blood is lost from cardio system OR when..
Plasma portion of blood is lost.
contractility
how hard the heart squeezes
diffusion
movement of molecules from an area of high concentration to a lower concentration. doesnt require energy
what is responsible for converting glucose and other nutrients into energy within a cell?
mitochondria
what does tone do for the body
helps regulate blood pressure and maintain perfusion
what is tone?
The amount of constriction in a blood vessel
what happens when a blood vessel suffers a “loss of tone”
A decrease in blood pressure and perfusion
shock
inability of the body to circulate blood the the body’s tissue and cells. Carbon dioxide will not be removed from the tissues
Ventialtion/ perfusion mismatch
They are never exactly matched. Both happen without obstruction. When altered mismatch occurs
when a capillary allows fluids to leave through its walls its said to be..
permeable
what is the difference between respiration and ventilation
Ventilation- process of moving air in and out of lungs
Respiration- exchange of gasses between alveoli, RBCs and cells of the body
Preload
The amount of blood filling the ventricle of the heart prior to contraction
delayed capillary refill time is the sign of..
compensated shock
distributive shock what is lost
blood vessel tone
the product of tidal volume and ventilation rate is
minute volume
the effect of oxygen in the body
allows continuation of aerobic metabolism
person breathing too slowly will have
decreased minute volume
afterload
pressure the heart has to pump to force blood out into the system
