Personal Protective Equipment Personal Protective Equipment or PPE is very important to protect healthcare personal and prevent the spread of infection All PPE should be put on before entering a patient room or receiving a patient into your procedure room
Personal Protective Equipment Different types of isolation, i.e. airborne, droplet, or contact, require different combinations of PPE to be worn Check for the type of isolation the patient is on or an isolation precaution sign outside of the patient’s room to know what PPE is recommended
Personal Protective Equipment Hand Hygiene This is the single most important thing to prevent the spread of infection Can use soap and water or an alcohol- based hand rub An exception is when your hands are visibly dirty or after contact with chemicals (regardless of having worn gloves) – then hands must be washed with soap and water
Personal Protective Equipment Hand Hygiene Must be done: When hands are visibly soiled (* use soap and water) After coughing, sneezing or blowing your nose After personal hygiene Between patients Touching blood or body fluids regardless of whether gloves were worn After touching potentially contaminated surfaces Prior to invasive procedures After exposure to chemicals regardless of whether gloves were worn (* use soap and water)
Personal Protective Equipment PPE includes the following: Gowns Masks Eye Protection Gloves Once on, don’t touch your skin, clothes, or equipment underneath – take out what you need before you don the PPE
Donning Procedure (Putting On) 1. Hand Hygiene or
Donning Procedure 2. Gown – Yellow Isolation Gown Opening is to the back Gown should cover from neck to knees to wrist Tie at back at neck and waist
Donning Procedure 3. Masks Can be a procedure/surgical mask or N95 mask depending on the patient condition Check if there are isolation protocols associated with the patient or an isolation precaution sign outside the patient’s room to determine what is required Follow your workplace Occupational Health and Safety procedures and protocols as to what mask is needed
Donning Procedure Procedure/Surgical Masks N95 Respirators
Donning Procedure 3a. Procedure/Surgical Masks Secure the ties or elastics around your head or ears so the mask stays in place Fit snugly to your face, over nose and below chin Press metal strip at nose with 2 fingers of both hands and starting at bridge of nose roll down each side to shape mask around nose – Don’t pinch
Donning Procedure 3b. N95 Respirators Pre-stretch straps prior to donning Cup the N95 in your hand Position the N95 under your chin with nose piece up and stretch the straps over your head Press metal strip at nose with 2 fingers of both hands and starting at bridge of nose roll down each side to shape mask around nose – Don’t pinch Fit check the N95 (cover with hands and exhale sharply looking for leaks) – and adjust if necessary
Donning Procedure 4. Eye Protection Consists of goggles or a face shield Place over eyes or face and adjust to fit Goggles are worn over glasses
Donning Procedure 5. Gloves Pull the ends of the gloves over the cuffs of the gown
Donning Procedure Hand Hygiene should always be the first step Gloves should always be the last step
Doffing Procedure (Taking Off) General rules: Remove gloves and gown inside the patient’s room After leaving the patient’s room and closing the door (depending on isolation protocol), remove mask and eye protection The outsides of all PPE are considered contaminated and should not be touched
Doffing Procedure 1. Gloves Grasp the outside edge of a glove near the wrist and peel away from the hand, turning the glove inside out Hold the glove in the opposite gloved hand Slide ungloved finger or thumb under the wrist of the remaining glove Peel the glove off, making a bag for both gloves Put the gloves in the garbage Should be done without bare skin touching the outside surface of any glove
Doffing Procedure 2. Hand Hygiene or
Doffing Procedure 3. Gown Carefully undo ties Slide fingers under 1 cuff and pull hand into sleeve With hand in sleeve, hold other sleeve so 2 nd hand can be pulled into sleeve Pull both hands through, turning gown inside out and wrapping into ball Dispose of into hamper Bare skin should not touch the outside of the gown which is considered contaminated
Doffing Procedure 4. Hand Hygiene or
Doffing Procedure 5. Eye Protection Handle goggles or face shield by headband or ear pieces only Pull away from face Throw disposable items into garbage and clean reusable items with sani-wipes for reuse
Doffing Procedure 6. Mask or N95 Respirator Bend forward slightly and remove mask by touching only the straps or ties Throw the mask or N95 respirator in the garbage Do not touch the outside of the mask as it is considered contaminated
Doffing Procedure 7. Hand Hygiene or
N95 Respirator
N95 Respirator What is a respirator? It is a device that is used to protect the user from breathing in hazardous substances There are many different types of respirator depending on the hazardous substances
N95 Respirator What is the function of the N95 Respirator? To filter out particles in the air so they are not inhaled by the user Airborne diseases such as Tuberculosis, chicken pox and measles exist as bacteria or virus particles in the air that can be filtered out by the N95 respirator
N95 Respirator Your job duties may require you to be in contact with patients that are infected or are suspected of being infected with an airborne disease Wearing a NIOSH approved N95 respirator is one way to protect a healthcare worker from inhaling these infectious particles
N95 Respirator What does an N95 Respirator not protect against? Chemical vapors Gases Oxygen deficient atmospheres
N95 Respirator When does an N95 Respirator need to be worn? Check Infection Prevention and Control set guidelines for N95 use Read instructions posted outside isolation rooms as to what PPE is needed Know the department’s standard operating procedures for infection control When in doubt, ask for assistance
N95 Respirator What needs to happen before wearing an N95 Respirator? Must be clean shaven in area of face seal Must receive training on use, care, donning and doffing procedures Must pass a quantitative fit test – to know make and model of mask that fits the user
N95 Respirator Donning the N95 Respirator Select proper N95 that you have been fit tested for Stretch out elastic straps Hold mask in one hand Move elastic straps to the front of the mask Hold mask to face with one hand, fitting mask over chin, mouth and nose
N95 Respirator Donning the N95 Respirator With the other hand stretch top elastic strap over your head and adjust to fit comfortably at the crown of your head Stretch the bottom elastic strap over your head and adjust to fit comfortably under your ears
N95 Respirator Donning the N95 Respirator Ensure a snug fit over your nose and cheeks Use 2 fingers of both hand and starting from the bridge of your nose, roll and press the metal strip along the contour of your nose – Do not pinch!
N95 Respirator Donning the N95 Respirator Fit test With both hands over mask inhale deeply to ensure the mask adheres to your face Exhale sharply to check for any air leaks – readjust respirator if there are leaks
N95 Respirator Doffing the N95 Respirator Lean forward slightly Pull bottom elastic strap over your head Pull top elastic strap over your head Discard into garbage using the elastic straps and without touching outer surface of mask which is considered contaminated N95 respirators are for a single use only
Fit Testing Quantitative Fit Test Uses an instrument that measures the concentration of airborne particles inside the respirator and compares that to the number of airborne particles in the room air Provides a measured quality of fit
Fit Testing PortaCount Fit Testing Equipment
Fit Testing Quantitative Fit Test The person being tested wears a respirator that is attached to the machine – glasses are worn if normal The person being tested must not have smoked ½ hour prior to testing The person will exhale smoke particles into the respirator resulting in an erroneous score and most likely a fail No chewing tobacco or gum allowed Face must be clean shaven in the area of the face shield A cold will not affect test results
