What is tissue perfusion?
Blood flow and tissue perfusion are NOT the same thing. An increase in blood flow does not always mean that there is a parallel increase in tissue perfusion. While blood flow is generally understood as an increase in the total amount of blood flowing into an anatomic structure or region, tissue perfusion is the amount of blood that actually flow through the capillaries of the vascular bed of that structure or region. The important thing to remember is that nutrients and oxygen are delivered to the cells via the capillaries.
Which respiratory disorders produce an increase in dead space volume and how would this increase in dead space affect cellular respiration and metabolism?
Respiratory disorders such as pulmonary embolism and acute respiratory distress syndrome can increase dead space volume by impairing gas exchange in the lungs. An increase in dead space leads to a decrease in effective ventilation and can cause a mismatch between ventilation and perfusion, resulting in reduced oxygenation of blood. This can lead to impaired cellular respiration and metabolism due to a decrease in oxygen delivery to the tissues.
Does increase in CO2 increase or decrease respiratory rate?
An increase in CO2 levels typically leads to an increase in respiratory rate. This is known as the hypercapnic ventilatory response, where the body tries to eliminate excess CO2 by breathing more rapidly.
Is respiratory increase a symptom of alcohol abuse?
No
Which one isn't a symptom of alcohol abuse coma loss of body heat respiratory increase speech disruption motor disruption?
Respiratory increase
Can hydrogen ion concentration stimulate the respiratory center to increase the respiratory rate and tidal volume?
Yes
What is the strongest stimulus to increase respiratory rate and depth is to increase the blood concentration of?
Carbon dioxide
How is coronary perfusion rate related to blood pressure?
Coronary perfusion rate, which is the amount of blood flowing to the heart muscle, is closely related to blood pressure. Higher blood pressure can increase coronary perfusion rate, delivering more oxygen and nutrients to the heart. However, extremely high blood pressure can strain the heart and lead to heart problems.
When blood o2 decreases what happens to respiratory rate?
It will increase.
