What are the three types of dead space ventilation?ģ1. The portion of inspired air that does not reach the alveoli for gas exchangeģ0. As airway resistance increases, what happens to the respiratory rate? Dynamic compliance is measured during gas flow.Ģ7. Lung compliance is measured at the period of 0 gas flow. What is the difference between dynamic compliance and lung compliance? What is the normal airway resistance in the tracheobronchial tree?Ģ6. It is the forces in action that cause the pressure changes required to move gas in and out of the lungs.Ī law that states that velocity is directly proportional to the pressure of a liquid and is inversely proportional to the viscosityĢ5. It decreases surface tension in fluids, increasing the exchange of gases in the alveoli. It is composed of 90% phospholipids and 10% protein. What is pulmonary surfactant composed of, and how does it work? It can be determined by the change in volume divided by the change in pressure.Ī condition of too much force for the lungs’ elastic capability that can cause a ruptureĪ negative pressure ventilator that was invented in the 1920s that was primarily used to treat patients with polioĪ molecular cohesive force at the liquid-gas interfaceĪ law that states that the distending pressure of a bubble depends on the surface tension and size of the bubbleĢ2. What measures the elastic forces of the lungs? The difference between alveolar pressure and body surface pressureġ6. The pressure difference between two points in a tube or vessel How much does the normal pleural pressure change during quiet breathing? What is the pressure gradient at end-expiration?ġ3. What causes the pressure gradient change during respiration?Ī gas law that states that the volume and pressure of a gas have an inverse relationshipġ2. The change in pressure gradient from outside the body to the alveoli and lungs requires a pressure-gradient change in the opposite directionġ0. The change in pressure between two points What is the difference between atmospheric pressure and barometric pressure?
What is the normal range for barometric pressure?ħ. The force exerted by the air that surrounds the bodyĦ. The process of taking air into the lungs and expelling it into the atmosphere The exchange of gases providing the blood and tissues with oxygen and removing excess carbon dioxide The gas exchange between pulmonary capillaries and the alveoli
The gas exchange between systemic capillaries and cells
