Question	Answer
Which of the following is NOT part of the respiratory membrane?	thick layer of mucus lining the alveolus
For air to flow into or out of the lungs, there must be	a pressure gradient established between the atmosphere and the alveoli.

RESPIRATORY CONTROL CENTERS ARE LOCATED IN THE	MEDULLA AND PONS
THE AMOUNT OF AIR THAT CAN BE INSPIRED ABOVE THE TIDAL VOLUME IS CALLED	INSPIRATORY RESERVE

What are the factors affecting ventilation?

2 Factors affecting pulmonary ventilation In this section, you will examine the factors that regulate pulmonary ventilation, including pressure gradients, surface tension, airway resistance and compliance of the lungs.

What are the three physical factors that influence pulmonary ventilation?

Three physical factors influence the ease of air passage and the amount of energy required for ventilation.

• Airway resistance.
• Alveolar surface tension.
• Lung compliance.

What factors influence lung compliance?

Two factors determine lung compliance: elasticity of the lung tissue and surface tensions at air water interfaces. Two factors determine lung compliance – elasticity of the lung tissue and surface tensions at air water interfaces.

Which are the two main factors that influence resistance to airflow?

More simply put, it is the pressure difference between the mouth and alveoli of the lung, divided by airflow. Multiple factors can influence airway resistance, including airflow velocity, the diameter of the airway, and lung volume.

What increases lung compliance?

Two important factors of lung compliance are elastic fibers and surface tension. More elastic fibers in the tissue lead to ease in expandability and, therefore, compliance. Surface tension within the alveoli is decreased by the production of surfactant to prevent collapse.

What causes poor lung compliance?

Common causes of decreased lung compliance are pulmonary fibrosis, pneumonia and pulmonary edema. In an obstructive lung disease, airway obstruction causes an increase in resistance. During normal breathing, the pressure volume relationship is no different from in a normal lung.

What is specific lung compliance?

Specific pulmonary compliance is a widely used metric in neonatal mechanical ventilation, capturing the intrinsic ability of the lung to expand with pressure normalized by the functional residual capacity of the lung. Previous studies have found specific compliance to be similar for both neonates and adults.

What is a normal lung compliance?

Normal adult lung compliance ranges from 0.1 to 0.4 L/cm H20. Compliance is measured under static conditions; that is, under conditions of no flow, in order to eliminate the factors of resistance from the equation.

What are the signs of non compliant lungs?

Signs of non-compliant lungs may include high airway pressures for a given tidal volume. Lungs that have decreased in compliance will require higher airway pressures to deliver a given tidal volume.

What is the difference between compliance and resistance?

Resistance is the change in pressure divided by flow. Compliance is volume divided by change in pressure.

What is lung compliance and why is it important?

Compliance is the ability of lungs and pleural cavity to expand and contract based on changes in pressure. Lung compliance is defined as the volume change per unit of pressure change across the lung, and is an important indicator of lung health and function.

Does lung compliance increase with age?

In general, compliance increases with aging [7]. Compliance is an extrinsic parameter, which increases if alveolar sacs increase in size. Lungs with low compliance are stiff lungs and will require much greater pres- sure to reach a given volume.

What is the difference between lung compliance and Elastance?

Lung compliance is the volume change that could be achieved in the lungs per unit pressure change. Elastance, also known as the elastic resistance is the reciprocal of compliance, i.e. the pressure change that is required to elicit a unit volume change. This is a measure of the resistance of a system to expand.

How do you calculate compliance?

The following formula is useful to calculate compliance: Lung Compliance (C) = Change in Lung Volume (V) / Change in Transpulmonary Pressure {Alveolar Pressure (Palv) – Pleural Pressure (Ppl)}.

What is the formula for static compliance?

Compliance = Volume/ Pressure. Static Compliance (CST) is expressed in mL/cmH2O. “Stiff lungs” are said to occur when CST is < 25-30 mL/cmH2O.

What is the formula for dynamic compliance?

Dynamic compliance (Cdyn) VT = tidal volume; PIP = Peak inspiratory pressure (the maximum pressure during inspiration);

What are the types of compliance?

Different Types of Compliance Jobs

• Regulatory and Legal Compliance. Organisations are subject to ever-changing regulations set down by external regulators, which are often government agencies, stock exchanges or industry bodies.
• IT Compliance.
• Financial Services Compliance.

What are compliance functions?

Compliance function is thereto reasonably ensure that the. company is complying with all applicable laws, rules and. regulations, as well as internal codes of conduct, policies and. procedures.
