1.
The following are all types of controls (drive mechanisms) except for:
Correct Answer
B. Galvanic
Explanation
The question asks for the type of control mechanism that is not included in the given options. Pneumatic, fluidic, and electronic are all types of control mechanisms, but galvanic is not. Galvanic refers to the production of electricity by chemical action, so it is not a type of control mechanism.
2.
All current anesthesia ventilators are powered by _________ gas.
Correct Answer
O2
Explanation
All current anesthesia ventilators are powered by O2 gas because oxygen is essential for maintaining the patient's oxygenation and ventilation during anesthesia. O2 gas is used to deliver oxygen to the patient's lungs, ensuring an adequate supply of oxygen for the body's needs. It is a critical component in anesthesia delivery systems as it supports the patient's breathing and helps prevent hypoxia, a condition characterized by low oxygen levels in the body. Therefore, O2 gas is the preferred choice for powering anesthesia ventilators to ensure patient safety and well-being.
3.
In an ascending bellows during exhalation, the driving gas will vent to:
Correct Answer
C. Atmosphere
Explanation
During exhalation, the driving gas in an ascending bellows will vent to the atmosphere. The ascending bellows is designed to compress and push the gas out of the system, and since the atmosphere is the external environment, it acts as the destination for the vented gas. This allows for the removal of waste gases from the respiratory system and ensures that fresh air can be inhaled during the next breath.
4.
In an ascending bellows, during exhalation, the __________ will open and vent excess gas from the _____________.
Correct Answer
Spill valve
Circuit
Explanation
During exhalation in an ascending bellows, the spill valve will open and vent excess gas from the circuit.
5.
Bellows are classified by their motion during inspiration.
Correct Answer
False
Explanation
Bellows are not classified by their motion during inspiration. Bellows are actually a device used to produce a strong current of air by the controlled expansion and contraction of a flexible container. They are commonly used in various industries and applications, such as in musical instruments or in ventilation systems. The classification of bellows is based on their design, material, and application, rather than their motion during inspiration.
6.
Which of the following statements are true:
Correct Answer
D. If you have a machine driven by air and a leak occurs in the bellows you will have a decrease in FiO2
Explanation
If there is a leak in the bellows of a machine driven by air, it means that there will be a decrease in the amount of air reaching the patient. As a result, the concentration of oxygen delivered to the patient (FiO2) will also decrease. This is because the air being delivered is mixed with oxygen, and any loss of air will result in a lower oxygen concentration. Therefore, the statement "If you have a machine driven by air and a leak occurs in the bellows you will have a decrease in FiO2" is true.
7.
Which of the following statements are false:
Correct Answer
A. A piston is similar to an ascending bellows in the fact that they both move up during inspiration.
Explanation
A piston is not similar to an ascending bellows in the fact that they both move up during inspiration. A piston moves up and down in a reciprocating motion, while an ascending bellows only moves up during inspiration.
8.
The S-ORC Assembly is responsible for:
Correct Answer
C. Ensuring that the hypoxic mixtures are not given to the patient
Explanation
The S-ORC Assembly is responsible for ensuring that the hypoxic mixtures are not given to the patient. This means that it is designed to prevent the patient from receiving a mixture of gases that has a low oxygen content, which could be dangerous and potentially harmful. By monitoring and regulating the oxygen levels in the gas mixture, the S-ORC Assembly helps to protect the patient's health and safety during ventilation.
