Which instrument is shown in the given image?
Appeared in: DSSSB October 2024
Explanation
- The device in the image is a portable suction machine, confirmed by its key features.
- Visual evidence includes a carrying handle for portability, a clear collection canister for fluids, a pressure gauge, and a regulator knob.
- The label on the device explicitly identifies it as a 'PORTABLE PHLEGM SUCTION UNIT'.
- Its function is to create negative pressure to remove secretions like mucus or blood from a patient's airway.
Why Other Options Were Wrong
- Option B: An oxygen concentrator is a device that provides supplemental oxygen. It does not have a collection canister or components for suctioning fluids.
- Option C: An Intra-Aortic Balloon Pump (IABP) is a large, complex cardiac-assist device used in critical care to support a failing heart. It consists of a large console with a monitor and does not resemble the small, portable unit shown.
- Option D: An ECMO machine is a highly complex life-support system that oxygenates blood outside the body. It is a large piece of equipment used in the ICU and looks vastly different from the simple suction device.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of common portable medical equipment used in nursing as background academic context rather than a clinical decision trigger.
- Portable suction machines are vital for maintaining a patent airway in emergencies, during patient transport, and in home care settings.
- Nurses must be able to quickly identify and operate this equipment to prevent life-threatening airway obstruction.
- Proper technique, including setting the correct pressure and limiting suction duration, is crucial to prevent complications like hypoxia, mucosal trauma, and infection.
How to Approach the Question
- First, carefully examine the image provided. Identify key components of the device shown.
- Note the carrying handle, the transparent collection jar, the pressure gauge, and the control knob.
- Read any text visible on the device. In this case, 'PORTABLE PHLEGM SUCTION UNIT' is clearly written, which directly describes its function.
- Evaluate each option against your visual analysis. A 'Portable suction machine' perfectly matches the visual evidence and the text on the device.
- Consider the function of the other devices. An oxygen concentrator provides oxygen, while IABP and ECMO are large, complex life-support machines. These do not match the appearance or function of the item shown.
- Conclude that the instrument is a portable suction machine based on the overwhelming visual evidence.
