1) Patient “A” has a change in pressure of 5 resulting in a tidal volume return of 600. Patient “B” has a change is pressure of 5 resulting in a tidal volume of 250cc. Calculate the total compliance of the lungs and thorax for each patient. a. Once compliance has been figured; explain what is happening to patient “B”.

According to the concept of ventricular compliance, which of the following statements are true? a. Increased compliance implies that for the same pressure, volume is smaller. b. Decreased compliance implies that for the same pressure, volume is larger. c Increased compliance implies that if volume is the same, pressure must be higher. d. Increased compliance implies that for the same pressure, volume is larger. e. Decreased compliance implies that if volume is the same, pressure must be lower.

1. What is the function of surfactant? To decrease compliance (stretchability) To increase the radius of the bronchi To decrease surface tension which prevents the alveoli from collapsing 2. Which of the following does NOT influence the loading reactions at the lungs? Pulmonary edema The amount of hemoglobin in the blood The pO2 gradient across the respiratory membrane Blood pH 3 Which of the following does NOT play a role in keeping the lungs inflated? FEV1 Surfactant Residual volume Transpulmonary...

A: Determine the lung compliance when the intrapleural pressure is -5 cm H2O during inspiration and the lungs accept a new volume of 200 mL of air. B: Determine the frequency of breathing when the patient is receiving continuous mandatory ventilation in the control mode and has an inspiratory time of 2.2 seconds and an expiratory time of 4.3 seconds.

An increase in lung compliance can enhance oxygen unloading because 1. it reduces resistance to air flow through the bronchioles. 2. it reduces the humidification of the air and thus maintains a higher alveolar PO2. 3. more fresh air can enter the lungs, leading to a steeper PO2 gradient across the respiratory membrane. 4. it reduces the thickness of the respiratory membrane.

1. The demand for healthcare has: a) increased because there is more pollution. b) decreased because birthrates are lower. c)increased because more illnesses are treatable. d)decreased because people are healthier today. 2.Global care seeks to lower health care costs by: a)providing insurance to everyone arounmd the globe. b)insuraing people with pre-existing conditions. c)caring for all the issues related to one diagnosis. d)providing care for the unemployed cost-free. 3.The primary benefit of a Fees for Service (FFS) health plan is: a)prices...

11. A pulmonary disorder that compromises the integrity of elastic protein fibers in the lungs may cause an increased compliance, poor elastic recoil and collapse of small bronchioles and alveoli. This patient would exhibit all of the following EXCEPT: A decrease in vital capacity A decrease in FEV1 An increase in % oxyhemoglobin saturation Chest pain due to air trapping 12. The majority of CO2 is transported in the blood as: Dissolved in plasma HCO3- Carbaminohemoglobin Carboxyhemoglobin 13 Patients with...
