Question 1

What is the function of a defibrillator?

Accepted Answer

Deliver electric shock to the heart

Answer

A defibrillator is a critical medical device specifically designed to deliver a controlled electric shock to the heart. This shock is used to restore a normal heart rhythm in individuals experiencing life-threatening arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia. Its primary function is to reset the heart's electrical activity, potentially saving a patient's life.

Question 2

Which device helps patients with respiratory issues?

Accepted Answer

Ventilator

Answer

A ventilator is a medical device that provides mechanical ventilation by moving breathable air into and out of the lungs. It is essential for patients who are unable to breathe adequately on their own due to various respiratory issues, such as severe pneumonia, acute respiratory distress syndrome, or during surgery. The ventilator supports lung function, ensuring proper oxygenation and carbon dioxide removal.

Question 3

What does an ECG machine measure?

Accepted Answer

Heart electrical activity

Answer

An Electrocardiogram (ECG or EKG) machine measures and records the electrical activity of the heart. It detects the tiny electrical changes on the skin that arise from the heart muscle's electrophysiological pattern during each heartbeat. This information is crucial for diagnosing various heart conditions, including arrhythmias, heart attacks, and other cardiac abnormalities.

Question 4

Which biomedical device delivers medications over time?

Accepted Answer

Infusion pump

Answer

An infusion pump is a medical device that delivers fluids, such as nutrients, medications, or blood, into a patient's body in controlled amounts. These pumps are designed to administer precise volumes at specific rates over an extended period, ensuring accurate and consistent delivery of therapeutic substances. This controlled delivery is vital for patient safety and treatment efficacy.

Question 5

What is the main function of a dialysis machine?

Accepted Answer

Filter blood

Answer

The main function of a dialysis machine is to filter and purify the blood when a patient's kidneys are no longer able to perform this vital function adequately. It removes waste products, excess salts, and water from the blood, mimicking the natural role of healthy kidneys. This process is crucial for patients with kidney failure to maintain fluid and electrolyte balance.
