Exploring Hypoxia and Dyspnoea

What are the primary causes of hypoxia?

• Excessive exercise

• Reduced oxygen availability, Respiratory problems, anemia.

• Decreased C02 levels

• Increased carbon dioxide levels

In which type of hypoxia, oxygen therapy is useful?

• Hypoxic

• Anemic

• Stagnant

• Histotoxic

How does hypoxic hypoxia differ from other types?

• Hypoxic hypoxia occurs due to heart failure.

• Hypoxic hypoxia is related to capacity of tissues to extract oxygen

• Hypoxic hypoxia is caused by low environmental oxygen levels.

• Hypoxic hypoxia is caused by high carbon dioxide levels.

In which condition, hyperbaric oxygen therapy cannot be used?

• blood loss anemia

• gas gangrene

• Pneumothorax

• CO poisoning

What role does altitude play in causing hypoxia?

• Altitude increases oxygen availability for breathing.

• Hypoxia is caused by high humidity at low altitudes.

• Altitude has no effect on oxygen levels in the atmosphere.

• Altitude causes hypoxia by reducing the partial pressure of oxygen available for breathing.

PND Stands for

• Pneumonia Disease

• Paroxysmal Nocturnal dyspnoea

• Pulmonary dyspnoea

• Para nocturnal Diseases

What is dyspnoea ?

• Dyspnoea is the sensation of difficult breathing

• Dyspnoea refers to a feeling of euphoria during exercise.

• Dyspnoea is a condition of decreased oxygen in the tissues

• Dyspnoea is a collective term used for lung diseases.

List some common causes of dyspnoea.

• COPD

• High blood pressure

• Skin rash

• Diabetes

How can oxygen therapy help in treating dyspnoea?

• Oxygen therapy eliminates the need for medication in all cases.

• Oxygen therapy increases oxygen availability in the bloodstream, alleviating breathlessness

• Oxygen therapy increases lung capacity permanently.

• Oxygen therapy reduces carbon dioxide levels in the body.

DYSPNOEIC INDEX is
