Fig. 1. A sample of PPE setup. A N95 mask must be of correct size and worn properly. Another surgical mask with a face shield is worn over the N95 mask to prevent the N95 mask from being contaminated. The N95 mask, when used properly, can be reused for up to 1 month. Gloves must be worn so that they cover the sleeves and not leave any skin in contact with the body fluid of the patient. Great care must be taken when removing the PPE, not to contaminate oneself or the surrounding. Any equipment not fully covered by the surgical gown, such as X-ray thyroid shields, should be disinfected after the procedure. PPE: personal protective equipment.
