- 4. SUCTION MACHINE Introduction • Inmedicine, devices are sometimes necessary to create suction. Suction may be used to clear the airway of blood, saliva, vomit, or other secretions so that a patient may breathe. Suctioning can prevent pulmonary aspiration, which can lead to lung infections. In pulmonary hygiene, suction is used to remove fluids from the airways , to facilitate breathing and prevent growth of microorganisms.
- 5. SUCTION MACHINE Introduction • Suctionmachines are appliances that are A portable suction unit can prevent pulmonary aspiration and facilitate breathing. Suction machine supplies include bacteria filters, collection canisters, and aspirator tubing kits. • Suctioning is a procedure that removes excess secretions from the mouth and throat (oropharynx), from the nose and throat (nasopharnyx), and from the windpipe (trachea) using a mechanical aspiration device (Suction machine).
- 6. SUCTION MACHINE Introduction • Suctiondevices may be mechanical hand pumps or battery or electrically operated mechanisms. In many hospitals and other health facilities, suction is typically provided by suction regulators, connected to a central medical vacuum supply by way of a pipeline system. The plastic, rigid Yankauer suction tip is one type of tip that may be attached to a suction device. Another is the plastic, nonrigid French or whistle tip catheter.
- 7. Uses of SuctionMachines 1. To remove blood during surgery to clear the area of surgery. 2. To remove the mucous from the throat so that the medical procedures can be carried out without obstruction from mucous. 3. To remove blood that has built up within the skull after an intracranial hemorrhage. 4. To remove substances such as blood, saliva, mucus, and vomit from a person's airway.
- 8. Indications for Suctioning: •The primary indication for suctioning the patient at home is the patient’s inability to adequately clear the airway by coughing. The need for clearing the airway is evidenced by: • More frequent or congested-sounding cough. • Visible secretions. • Audible gurgling noise while breathing. • Suspected aspirations of gastric or upper airway secretions .
- 9. Operating the SuctionMachine: • Plug the suction machine into a grounded outlet. • Check that the tubing from the machine to the collection jar is on • and snug. • Check that the lid to the collection jar is closed tightly. • Attach the extension tubing to the collection jar. • Turn the machine on and kink the extension tubing to block the flow of air. • -If the pressure gauge did not move when kinking the tubing, recheck all of your connections. Look for leaks in the system. The lid may not be closed tightly; a tub may not be on properly or the tube in punctured. • Look at the pressure gauge. Using the control dial, set the gauge pressure between 15” and 20” of Hg. (for an adult) • -An infant or a child will use less pressure. Consult with doc tor or call • therapist. • After the pressure is set, connect the oral suction device (Yankauer Suction Tip) or suction catheter to the suction extension tubing.
- 10. Equipment and Supplies Needed: •Electric or battery powered aspirator with pressure gauge and • collection jar with overflow protection . • Suction catheters (sized appropriately) • Tap water that has been boiled and stored in a closed, clean container. Water needs to be used within 24 hours of boiling to flush the catheter. o Water from the tap that is not boiled will increase the risk of contamination and infection. • Clean or sterile disposable gloves • A manual resuscitator bag (for hyperinflation of the lungs if medically indicated) • An oxygen source (when pre-oxygenation is medically indicated) • Sterile normal saline (for instillation when medically indicated) • Oral suction device (Yankauer Tonsil Tip) • Sterile distilled water, and/or recently boiled water and cleaning solution (alcohol or hydrogen peroxide)
- 11. Preparing the Patientfor Suctioning: • Whenever possible, the patient should be encouraged to clear the airway by directed cough or other airway clearance techniques. The patient’s response to suctioning during their stay in the acute care or long-term care facility should be made a part of the discharge summary and the health care professional establishing the patient in the home should request this information.
- 12. Caregiver Training: • Thecaregivers or family members that will be taking care of the patient should be taught the proper suction techniques by qualified hospital personnel. The caregivers or family members should be trained to understand: • When it is necessary to suction • What type of suctioning is needed (oral vs. nasal tracheal) • They should be trained as to when it’s necessary to pre- oxygenate, preform normal saline instillations, use of the resuscitator bag to hyper inflate the lungs and then to deep suction.
- 13. Suctioning the Patient: •1.Use clean technique during suctioning in the home environment. Clean, non-sterile disposable gloves should be used when performing nasal tracheal deep suctioning. • 2.When deep suctioning and using a catheter, do not keep the suction engaged for longer than 5 seconds at a time. • 3.At the end of the suctioning event, flush the catheter or tonsil tip by suctioning recently boiled water or distilled water to rinse away mucus, followed by suctioning of air through the device to dry the internal surface and discourage microbial growth. • 4.The outer surface of the device may be wiped with alcohol or hydrogen peroxide. The suction catheter or tonsil tip should be allowed to air dry and then stored in a clean, dry area.
- 14. • 5. Replacethe suction catheter every 24 hours. Tonsil tips can be boiled, and reused indefinitely. Store the cleaned catheter or tonsil tip so that they are not directly exposed to the air. (Cover with clean, lint-free, paper towels, or store in a clean container). • 6.Only suction the patient if they are in distress, or you see or hear ‘wet’ breath sounds. When suctioning, look at the patient. Don’t become so engrossed with the procedure that you become unaware of the patient’s reactions and responses. Remember; don’t actively keep the suction on for more than 5 seconds if using a catheter and performing deep suctioning or for 10 seconds if using the tonsil tip. Let the patient regain their breath.
- 15. • 7.Observe thepatient after the suctioning procedure. Are the visible secretions gone? Has the gurgling wet breath sounds stopped or at least greatly diminished? Does the patient appear more comfortable and less distressed? Observe the skin color. (Including the presence or absences of cyanosis). Get into the habit of monitoring the pulse rate before and after suction. Take blood pressure and Oximetry if they have the equipment. Look at the color of the sputum. Are there any changes in the color? Keep doctor’s office informed of the color changes. Is there an odor to the sputum? Again, keep the doctor’s office informed.
- 16. Cleaning: • 1.The suctioncanister ( cylindrical container ) should be emptied daily and washed, along with the connecting tubing, in hot water and mild dishwashing detergent. Rinse with clean, hot tap water. It is recommended that these items be disinfected daily with a solution of one part white vinegar and 3 parts water. Allow the items to soak for 30 minutes and then rinse with clean, hot tap water. • 2.All caregivers should practice reasonable infection control procedure in the home setting. Patients should be protected form visitors and caregivers with active viral and bacterial infections. Or the opposite is true if the patient has yet to be diagnosed with the organism they are carrying which could be spread to others by droplet infection.
- 17. USES • Suction machinesused in the homes are usually for helping people with respiratory problems. When a patient or an elderly person is not able to clear the lungs and airway of mucus or serum, then an aspirator can be used to suck out the fluids. • Tracheostomy care also involves use of suction machines for removal of secretions from the trachea, nasopharynx and oropharynx thereby maintaining hygiene of the trachea. Suction machines may also be used in cases when someone has a moist cough and is not able to clear secretions from the throat effectively. • Components of a suction machine typically include suction pump, connection and patient tubings, disposable canister with lid, rechargeable battery, power cord and bacteria filter. • The bacteria filter prevents back flow from the canister and airborne • contaminants from entering and damaging the pump.
- 18. • A yankaueris used to aspirate secretions from either a surgical site or a body orifice. Its tip is slightly crooked so as to prevent smooth passage into the throat without fragile tissue being damaged. • Selection of suction machines or aspirators stands out for their powerful suction force, reliability and high performance. Portable suction machines are small enough to be fit into a travel bag and can easily be transported anywhere. • Suction machines today are lightweight, portable and technologically sophisticated. The most clogged airway can be cleared up quickly through strong, powerful machines returning the patient to the state of comfort. Some of these aspirators have adjustable vacuum pressure needed especially when working with children or an elder people.
