What is the gas volume in the lung after a maximum inspiration?

6-8L

Which lung disease is characterized by a decrease in Total Lung Capacity (TLC)?

Restrictive disease

What is the volume left in the lung after a maximum expiratory effort?

2L

Which parameter is calculated as Total Lung Capacity (TLC) minus Residual Volume (RV)?

Vital Capacity (VC)

In Obstructive Lung Disease, which spirometric measure represents the volume of air that can be forcefully exhaled in 1 second?

Forced Expiratory Volume in 1 second (FEV1)

Which spirometric measure directly indicates airflow obstruction?

Forced Expiratory Volume in 1 second (FEV1)

What is the purpose of pulmonary function testing according to the text?

To support diagnostic reasoning, not as a risk assessment tool

Which of the following is mentioned as a risk factor for postoperative pulmonary complications?

Low albumin levels

What is the significance of lung volumes, specifically FRC?

Determining the amount of air in the lungs after ordinary expiration

Why should pulmonary function testing not be used as a risk assessment tool according to the text?

It is more suitable for diagnostic reasoning support

Which factor does NOT contribute to an increased risk of postoperative pulmonary complications?

Normal chest exam findings

What is the primary focus of determining risk factors according to the text?

Identifying individuals at risk for post-op pulmonary complications

In restrictive lung disease, the Total Lung Capacity (TLC) can increase up to 12L.

False

Forced Expiratory Volume in 1 second (FEV1) represents the volume of air that can be forcefully exhaled in 1 second.

True

Vital Capacity (VC) can be calculated as the sum of Total Lung Capacity (TLC) and Residual Volume (RV).

False

Forced Vital Capacity (FVC) measures the volume of air that can be exhaled with maximum effort in 1 second.

False

Airflow through the mid-point of exhalation is indicated by Forced Expiratory Flow between 25% and 75% of Forced Vital Capacity (FEF25-75%).

True

What is the main determinant of CO2 removal in the lungs?

Alveolar ventilation

Which factor decreases the Functional Residual Capacity (FRC) to levels close to awake Residual Volume?

General anesthesia

What causes ventilation-perfusion (V/Q) mismatch and shunts during general anesthesia?

Airway closure

What is the most serious adverse respiratory outcome related to in the text?

Hypoxemia

Which lung volume indicates the amount of air in the lungs after ordinary expiration?

Functional residual capacity

What factor is NOT mentioned as a risk factor for postoperative pulmonary complications in the text?

Planned local anesthesia

Which lung disease can cause a decrease in Total Lung Capacity (TLC) down to 3-4L?

Restrictive disease

What spirometric measure indicates airflow through the mid-point of exhalation?

Forced Expiratory Flow between 25% and 75% of FVC (FEF25-75%)

What is the volume left in the lung after a maximum expiratory effort?

RV

Which parameter is calculated as Vital Capacity (VC) minus Residual Volume (RV)?

Forced Vital Capacity (FVC)

What spirometric measure directly reflects airflow obstruction and can be reduced in both obstructive and restrictive diseases?

FEV1
