what is suction apparatus? 

A suction apparatus, also known as an aspirator, is a medical device used to eliminate fluids or gasses like mucus, vomit, blood, saliva, serum, or other secretions from the body cavities of a patient. These cavities may include the lungs, mouth, or even the skull.

Suction apparatuses find utility in various situations, including when a patient is unconscious, experiencing vomiting, or having seizures. They are also employed during ongoing medical procedures. Whether it is a single-jar suction apparatus or a double-jar suction apparatus, these devices serve several essential functions in pre-hospital, in-hospital, and continuous patient care beyond just removing obstructions:

  • Preventing pulmonary aspiration by clearing the airways.
  • Preventing the backflow of liquids into the body.
  • Facilitating breathing by maintaining clear air passages.
  • Inhibiting the growth of microorganisms.
  • Allowing medical professionals to work in the targeted area without interference.

Suction apparatuses play a critical role in maintaining patient well-being and supporting various medical procedures by effectively and safely removing fluids or gasses from the body.

What Are The Different Types Of Suction Apparatus 

Medical suction machines have evolved, starting from manual devices in the 1860s to modern electrical machines. Today, different types of  hospital suction machines are available, catering to various medical needs.

  • Manual suction machines: These devices operate without electricity or batteries, making them portable and suitable for emergencies outside the hospital. They are compact, lightweight, and easy to use.
  • Wall-mounted suction machines: Installed in hospital rooms or ambulances, these electrical machines provide reliable and consistent suction. They require a constant power supply and are commonly used during surgeries as part of standard medical procedures.
  • Portable suction machines:  Portable suction machines are designed for mobility, portable suction machines run on batteries and can be easily moved from one location to another. They are lightweight, user-friendly, and handy for patients receiving palliative care or those unable to clear secretions independently, such as individuals with COPD, cystic fibrosis, or ALS. In emergencies like accidents or respiratory emergencies, portable suction devices can be life-saving tools.

These various types of suction apparatuses ensure that medical professionals have access to efficient suction capabilities in different settings, allowing for adequate airway clearance and removing fluids or secretions from patients’ body cavities.

How To Use Suction Machines? 

Suction machines use negative pressure to remove secretions from a person’s oral cavity. The device consists of several components that work together to create this negative pressure:

  • Vacuum pump: This component generates the negative pressure required for suctioning.
  • Connecting tubes: These tubes connect the vacuum pump to the collection canister.
  • Sterile patient tube: This tube carries the secretions from the patient into the collection canister.
  • Disposable canister: The canister holds the secretions and prevents contamination of other parts of the suction machine.
  • Filters: Filters are used to prevent contamination of the internal components of the suction machine by viruses, bacteria, dust, and gasses.
  • Batteries and power cord: These power the machine for operation.

To use the suction machine, follow these steps:

  • Wash and disinfect your hands.
  • Turn on the device and connect the connecting tubes.
  • Attach a clean and dry suction catheter to the connecting tubes.
  • Position the patient flat on their back or seated with a rolled towel under their shoulders.
  • Use sterile or distilled water to lubricate the catheter and check the machine’s functionality.
  • Carefully insert the catheter into the tracheostomy tube, ensuring their lengths match.
  • Place your thumb over the suction vent and remove it within 5-10 seconds.
  • Allow the patient to rest and repeat suctioning if necessary.
  • Once the procedure is complete, turn off the machine and discard the catheter.

Cleaning the suction machine is crucial, as some parts are single-use and should be disposed of properly. Non-disposable parts require frequent cleaning to remove hazardous contaminants. Wear personal protective equipment (PPE) while handling contaminated waste and dispose of single-use parts according to local medical waste disposal protocols.

Avoid introducing substances like grease or oil into the machine’s components, and refrain from excessive water use or abrasive cleaners that may damage the parts.

Following proper usage and cleaning guidelines ensures the safe and effective operation of the suction machine, promoting patient care and preventing contamination risks.

What is the purpose of a suction tool?

Adhering to proper guidelines for safe and effective suctioning is crucial when A suction machine, also referred to as an aspirator, is a medical device primarily designed to eliminate blockages, such as mucus, saliva, blood, or secretions, from an individual’s airway.

What signals the need for suctioning?

Suctioning is warranted in cases such as the detection of abnormal lung sounds (rhonchi) or coarse crackles during auscultation over the trachea, mainstem bronchi, or both. It is also necessary in the event of a gradual or sudden decline in oxygen saturation or an increase in peak airway pressures while a patient is undergoing mechanical ventilation.

What is the recommended frequency for suctioning a patient?

The number of times a patient needs suctioning depends on factors like the volume of secretions and the patient’s capacity to clear them. Although there is no universal agreement, it is generally advisable to assess airway patency and attempt suctioning at least every 8 hours. The decision to suction should be based on the patient’s specific condition and clinical judgment, as the necessity for suctioning may vary.

What precaution should be taken with a Medical suction machines?

A crucial precaution during Medical suction machines use is to avoid prolonged suctioning. Suctioning a patient for over 15 seconds elevates the risk of complications and hypoxia. It is advisable to withdraw the catheter, administer supplemental oxygen to the patient, and proceed with suctioning if needed. This strategy minimizes the risk of oxygen depletion and promotes safer suctioning practices.
