Q1: The gases used in the treatment of asthma is a mixture of __________ and oxygen.

ANS:A - helium

The gases used in the treatment of asthma are a mixture of helium and oxygen. Explanation:

1. Heliox Therapy: Heliox therapy is a medical treatment used for managing respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It involves the administration of a gas mixture containing helium and oxygen.
2. Helium: Helium is an inert gas that is lighter than air. When mixed with oxygen, it can be used to deliver respiratory support to individuals experiencing airway obstruction or respiratory distress. Helium has lower density and viscosity compared to nitrogen (which makes up the majority of air), allowing for easier flow through narrowed airways.
3. Oxygen: Oxygen is essential for respiration and is commonly administered to patients with respiratory conditions to improve oxygenation and alleviate hypoxemia (low blood oxygen levels). When combined with helium in a heliox mixture, oxygen helps to maintain adequate oxygenation while the helium improves gas flow and reduces airway resistance.
4. Argon and Neon: Argon and neon are inert gases like helium, but they are not typically used in respiratory therapy for conditions such as asthma. While argon and neon have their own applications in other fields (such as welding and lighting), they are not commonly used in medical settings for respiratory support.
