What else can I help you with?
In the circular flow model what generates demand for goods and service?
production
What determines the magnitude of circular flow of income and expenditures?
Aggregate demand
Demand is a flow concept justify?
Demand is a flow concept because our willingness and ability to buy is subjected to a timeperiod. At different times, we may have different demand schedules.
Is the price elasticity constant along the demand curve?
Price elasticity of demand is equal to the instantaneous slope of the demand curve, or the slope of the tangent line at any point on the demand curve. So if the demand curve is represented by a straight downward sloping line, then yes, price elasticity of demand is equal to the slope of the demand curve. Otherwise, the slope at any point on the curve is changing, and you can find the it by taking the derivative of the demand curve function, which will find the Price elasticity of demand at any single point. Thus, the Price Elasticity of Demand changes at different points on the demand curve.
Theory of demand supply?
The theory of supply and demand is that when supply are plentiful, they are typically more affordable and easier to find. When supply is low, demand and prices increase as a result.
What is inspiratory flow rate?
Inspiratory flow rate refers to the rate at which air is taken into the lungs during inhalation. It is typically measured in liters per minute and can vary depending on factors such as lung function and respiratory conditions. Changes in inspiratory flow rate can help in diagnosing and monitoring lung diseases.
What is the difference between time cycled and flow cycled ventilator?
In a time-cycled ventilator, the breath is delivered for a set period of time, regardless of patient effort, while in a flow-cycled ventilator, the breath is delivered until a preset flow rate is reached. Time-cycled ventilation is independent of the patient's respiratory effort, whereas flow-cycled ventilation is dependent on the patient's inspiratory effort.
What is inspiratory pressure?
Inspiratory pressure refers to the amount of pressure generated during inhalation to expand the lungs and allow air to flow into the respiratory system. It is measured in centimeters of water pressure and is an important parameter to evaluate respiratory function, especially in conditions like asthma or COPD. Inspiratory pressure can be influenced by factors such as lung compliance and airway resistance.
What is the difference between stridor and wheeze?
wheeze can be inspiratory or expiratory but stridor is mostly inspiratory
What is the medical term meaning the amount of air that can be inspired above the tidal volume?
Inspiratory reserve volume is the volume you can inhale past the normal tidal volume.
What in peak inspiratory pressure?
The maximum pressure exerted against the patients airway during the breath.
Why does eRV decrease during exercise?
Inspiratory Reserve Volume is the excess volume above the tidal volume that can be inspired. During exercise, there is an increase in demand for oxygen which leads to a decrease in IRV.
What is an oxygen conserving device?
An oxygen conserving device regulates the flow of oxygen delivered to a patient only when they inhale, as opposed to a continuous flow. This helps conserve oxygen, extend the life of oxygen tanks, and make portable oxygen therapy more manageable. The device can be incorporated into portable oxygen concentrators or tanks.
What is the normal Peak inspiratory flow in males?
The normal peak inspiratory flow (PIF) in males typically ranges from about 400 to 700 liters per minute, depending on factors such as age, height, and overall lung function. This measurement can vary significantly among individuals. PIF is an important parameter in assessing respiratory health, particularly in conditions like asthma or chronic obstructive pulmonary disease (COPD). It is often measured using a peak flow meter during pulmonary function tests.
What are the acute and chronic effects of exercise on Inspiratory and Expiratory residual volume?
ACUTE EFFECT - The inspiratory and expiratory volume decreases during exercise
What is the difference between peak inspiratory pressure and plateau pressure?
Peak inspiratory pressure refers to the maximum pressure reached during inspiration, while plateau pressure refers to the pressure measured when there is no airflow in the lungs at the end of an inspiratory pause. Plateau pressure is a better indicator of lung distensibility and risk of overinflation compared to peak inspiratory pressure.
Asthma has inspiratory dyspnea or expiratory dyspnea?
Expiraroty dyspnea (remember all pulmonary diseases have expiratory or mixed dyspneas and heart diseases are differentiated by inspiratory dyspneas)
