Questions: Which of the following is not a desired characteristic of a suction device? A. It can be carried in an airway kit with an oxygen cylinder and other airy equipment B. It can be hand powered or battery powered C. It can generate sufficient suction and volume displacement to remove food, blood clots, and thick secretions from the oropharynx D. It can be powered by your portable O2 cylinder so it is not dependent power

The answer is D: It can be powered by your portable \( \mathrm{O}_{2} \) cylinder so it is not dependent on power.

Explanation for each option:

A. It can be carried in an airway kit with an oxygen cylinder and other airy equipment - This is a desired characteristic because portability and ease of transport are important for emergency medical equipment.

B. It can be hand powered or battery powered - This is a desired characteristic as it provides flexibility in power sources, ensuring the device can be used in various situations, including those where electricity is not available.

C. It can generate sufficient suction and volume displacement to remove food, blood clots, and thick secretions from the oropharynx - This is a critical desired characteristic because the primary function of a suction device is to effectively clear the airway of obstructions.

D. It can be powered by your portable \( \mathrm{O}_{2} \) cylinder so it is not dependent on power - This is not a desired characteristic because using an oxygen cylinder to power a suction device is not practical or standard practice. Suction devices typically have their own power sources, such as batteries or manual operation, to ensure they are always ready for use without depleting oxygen supplies.

In summary, option D is not a desired characteristic of a suction device.
