Question

Which of the following are conditions that can contribute to a decrease in lung compliance leading to ineffective BMV?

1) Pulmonary edema
2) Pulmonary hypertension
3) Pulmonary embolism
4) ARDS

Answer 1

Conditions that can contribute to a decrease in lung compliance leading to ineffective BMV (bag-mask ventilation) include pulmonary edema, pulmonary hypertension, pulmonary embolism, and ARDS (acute respiratory distress syndrome).

Step-by-step explanation:

Lung compliance refers to how elastic the lung tissue is. A decrease in lung compliance can lead to ineffective BMV (bag-mask ventilation). Conditions that can contribute to a decrease in lung compliance include:

1. Pulmonary edema: Fluid accumulation in the lungs can cause the lung tissue to become less compliant.
2. Pulmonary hypertension: Increased blood pressure in the pulmonary arteries can lead to structural changes in the lung tissue, reducing compliance.
3. Pulmonary embolism: A blood clot in the pulmonary blood vessels can obstruct blood flow, leading to decreased compliance.
4. ARDS (acute respiratory distress syndrome): In ARDS, the lung tissue becomes stiff and less compliant due to inflammation and fluid accumulation.

These conditions can interfere with the ability of the lungs to expand and contract properly, making bag-mask ventilation less effective.
