Imagine that when you go to a hospital or a clinic, you must have seen a doctor or a nurse wearing gloves and maybe a mask on their face, right? That's what personal protective equipment , or PPE (Personal Protective Equipment) is for. These are not just pieces of clothing or fashion. These are like our shields that protect you and the healthcare workers who treat you from various dangers, especially from the spread of diseases. So, knowing what these PPE types are and how to use them is very important for you, your family, and everyone around you.
What is PPE? Why is it so important?
Simply put, PPE can be any piece of clothing or equipment that can protect you from various harms. PPE is especially essential in the healthcare field. Because it not only protects those providing medical services, but also you who receive medical services.
Think about it this way. Before treating you, the doctor or nurse applied medicine to someone else's wound. Then they wouldn't come to you wearing those used gloves, would they? They would take off those old gloves, wash or ``sanitize'' their hands, and then treat you with a new, clean pair of gloves. That's the importance of PPE. It protects both of you.
Also, there are some types of PPE that are `fitted` to the person using them, or that require special training to use. Let's now look at what types of PPE are used in this medical field.
Types of PPE used in the medical field
There are several types of PPE used primarily in the medical field:
- Face and respiratory protection equipment
- Gloves
- Clothing that covers and protects the body
Let's talk about each of these in detail.
1. Equipment that protects the face and respiratory system
This category mainly includes the following:
- Face masks: These are the simplest masks that cover the nose and mouth. These are the masks that are used during times of illness, such as the flu or when a doctor is giving you a routine checkup. Although they may look like ``Surgical masks'', they are not always of the same quality.
- Surgical masks: These are similar to face masks, but come in different thicknesses and filtering levels. They must meet stricter standards than regular face masks (for example, in the United States, the Food and Drug Administration (FDA) sets these standards. Health authorities in our country also set rules for this).
- Eye protection: Face shields and goggles provide physical protection for the eyes.
- Filtering facepiece respirators (FFRs): These come in different types and filtration levels. For example, they are called `N95` masks, or `Powered Air-Purifying Respirators (PAPRs). They need to fit snugly around the face, creating an `airtight seal` around the nose and mouth. Some have integrated eye shields.
2. Gloves
Not all gloves used in the medical field are the same. There are many different types, from simple exam gloves used for routine examinations to sterile surgical gloves. Also, thicker gloves used when handling certain medications or chemicals fall into this category.
3. Clothing that covers and protects the body
This includes everything from the general scrubs worn by doctors and nurses to other specialized clothing. Here are some of the most protective coverings:
- Aprons: These can be disposable or reusable, and there are aprons made of different materials to suit different occasions.
- Gowns: There are different types of gowns, such as `surgical gowns` and `nonsurgical gowns`. These are commonly used in hospitals and clinics.
- Coveralls: These provide more coverage and protection than an apron or gown. They are designed to cover the entire body.
- Foot coverings: There are many types, from disposable shoe covers to boots that can protect against liquids or chemicals.
- Head coverings: Some PPE devices are designed to cover the entire head in the form of a large hood. These can protect the head from germs and body fluids.
What are the types of PPE precautions?
Now let's talk about when and what type of PPE to use. Experts organize these types of PPE according to how the disease is transmitted (transmission-based precautions) . That is, the type of PPE needed is determined by how a particular disease spreads.
It is very important that the use of gloves is standard at all levels of precaution. Also, the use of face masks and surgical masks is common, depending on the situation.
There are four main types of precautions to take, depending on how the disease is transmitted:
- Bloodborne
- Transmission by contact
- Transmission by respiratory droplets (Droplet)
- Airborne transmission
Let's look at these one by one.
1. Bloodborne precautions
These are widely used in many medical situations. In such situations, health workers definitely use gloves. Not only that, but other equipment may also be used depending on the situation. For example:
- Mask
- Eye and face masks
- Body coverings (such as aprons, gowns)
- Equipment needed for the safe handling and disposal of sharps (such as needles)
2. Contact precautions for diseases transmitted by contact
These precautions are taken to protect against diseases that can be spread from person to person or by touching an object or surface. Standard PPE for this is gloves and disposable gowns . For example, if a doctor needs to use a common piece of equipment like a stethoscope, they will use a ``single-use disposable`` one.
Some examples of diseases transmitted by contact:
- Methicillin-resistant Staphylococcus aureus (MRSA) infections
- Gastrointestinal infections, such as Norovirus or Clostridium difficile (C. diff)
- Other common injuries or skin infections
If there is a risk of contact with bodily fluids when treating a patient like this, healthcare workers use additional protective equipment.
3. Droplet precautions for diseases transmitted by respiratory droplets
These precautions are taken to protect against diseases that are spread through small droplets (`droplets`) that come out of our mouths and noses when we cough, sneeze, breathe, and talk. For example, these precautions are necessary for viral diseases like `Influenza` and `COVID-19`. The PPE used for this is:
- Face and eye coverings such as surgical masks, face shields, or goggles
- Body coverings such as gowns, aprons, and coveralls
- Foot coverings, such as boots or shoe covers
4. Airborne precautions
This is the most stringent precautionary measure . It is used to protect against germs that cannot survive in the air or on surfaces for long periods of time. The PPE required for this is:
- Specially fitted respirators, for example `FFRs (such as N95)`
- Eye and face masks
- Body coverings such as aprons, coveralls, or disposable gowns
- Foot coverings, such as boots or shoe covers
Examples of airborne diseases:
- Diseases caused by bacteria, such as `Tuberculosis` or `Anthrax`
- Measles, caused by viruses, or some highly contagious types of herpes zoster (shingles) (another disease that affects people who have had chickenpox)
What are the types of non-medical PPE?
Even beyond medical settings, using PPE can prevent serious injuries or illnesses. Here are some examples of non-medical PPE:
- Respiratory protection: To filter tiny particles emitted during activities such as carpentry, excavation, and mining. They are also used to protect against toxic fumes from paints and chemicals.
- Protecting body parts from accidents: helmets, reinforced boots to protect feet from heavy objects, etc.
- Hearing protection: Use earplugs or other devices to protect your ears from loud noises.
- Eye protection: Things like shielding eyewear (which prevent retinal burns) used by welders, and impact-resistant glasses or shields to protect the eyes from flying debris.
- Food Safety: Things like hairnets and gloves can help prevent many foodborne illnesses.
There are some types of PPE that are specific to a specific hazard. Examples:
- Heat-resistant clothing and turnout gear worn by firefighters.
- Rubber gloves are used to protect against electricity.
- Ripstop garments are used to protect against fast-moving machinery such as chainsaws.
- Chemical-resistant garments and gear used in cases of toxic chemical spills.
- Military protective equipment, for example `MOPP (Mission-Oriented Protective Posture) gear`.
There are many other types of non-medical PPE, depending on the nature of the job or activity. If you want to know more about this, you can get help from government agencies in your area or country.
Finally, things to remember (Take-Home Message)
Personal protective equipment (PPE) is essential to keeping you safe and healthy. While it's a part of everyday life for those in some industries, there are plenty of ways that PPE can help everyone.
When you or someone in your family is receiving medical treatment, don't hesitate to ask for more information about infection control precautions. Understanding PPE and precautions can make a big difference for everyone involved. Don't be afraid to ask your doctor or nurse any questions you have. Your safety is their top priority, too!
