Disease
• Disease occurs only when the microorganism causes injury to the host

Universal Precautions
Since there is no way you can know if a person is infected, you should ALWAYS use universal precautions:
Wash your hands Wear gloves Handle sharp objects carefully Properly clean all spills Wear mask, eye protection, and apron if
splashing is a possibility.
![Page 20: Infection Control, Vital Signs, Oxygen & Medical Emergencies Warning: blood and guts to follow !](https://reader036.vdocuments.mx/reader036/viewer/2022062408/56649edd5503460f94bedc5b/html5/thumbnails/20.jpg)
Airborne Precautions
Patients infected with pathogens that remain suspended in air for long periods on aerosol droplets or dust.
TB, Chickenpox, Measles Respiratory protection must be worn when
entering pt room. Pt should wear mask.
![Page 21: Infection Control, Vital Signs, Oxygen & Medical Emergencies Warning: blood and guts to follow !](https://reader036.vdocuments.mx/reader036/viewer/2022062408/56649edd5503460f94bedc5b/html5/thumbnails/21.jpg)
Droplet Precautions
Patients infected with pathogens that disseminate through large particulate droplets expelled from coughing, sneezing, or even talking.
Rubella, Mumps, Influenza Surgical mask must be worn when within 3
feet of the pt. Pt should wear a mask.
![Page 22: Infection Control, Vital Signs, Oxygen & Medical Emergencies Warning: blood and guts to follow !](https://reader036.vdocuments.mx/reader036/viewer/2022062408/56649edd5503460f94bedc5b/html5/thumbnails/22.jpg)
Contact Precautions
Patients infected with pathogens that spread by direct contact with the pt or by indirect contact with a contaminated object (bedrail, pt dressing).
Methicillin-resistant staphylococcus aureus (MRSA), Hepatitis A, Varicella, Flesh-eating Virus
All PPE should be used and equipment must be disinfected after use.

Controlling the spread of Disease
• Chemotherapy
• Immunization
• Asepsis– Medical– Surgical
• Disinfectants
![Page 24: Infection Control, Vital Signs, Oxygen & Medical Emergencies Warning: blood and guts to follow !](https://reader036.vdocuments.mx/reader036/viewer/2022062408/56649edd5503460f94bedc5b/html5/thumbnails/24.jpg)

Physical Methods of Controlling Diseases
• Handwashing• Standard
Precautions– Gloving– Gowns– Face masks– Eyewear
![Page 26: Infection Control, Vital Signs, Oxygen & Medical Emergencies Warning: blood and guts to follow !](https://reader036.vdocuments.mx/reader036/viewer/2022062408/56649edd5503460f94bedc5b/html5/thumbnails/26.jpg)
Handwashing
Single most important means of preventing the spread of infection.
7 to 8 minutes of washing to remove the microbes present, depending on the number present.
Most effective portion of handwashing is the mechanical action of rubbing the hands together.
![Page 27: Infection Control, Vital Signs, Oxygen & Medical Emergencies Warning: blood and guts to follow !](https://reader036.vdocuments.mx/reader036/viewer/2022062408/56649edd5503460f94bedc5b/html5/thumbnails/27.jpg)
Types of Nosocomial Infections
Iatrogenic Infection – related to physician activities
Compromised Patients - weakened resistance; immunosuppressed
Patient Flora - microbes in healthy people Contaminated Hospital Environment Bloodborne Pathogens – Hepatitis B and HIV
![Page 28: Infection Control, Vital Signs, Oxygen & Medical Emergencies Warning: blood and guts to follow !](https://reader036.vdocuments.mx/reader036/viewer/2022062408/56649edd5503460f94bedc5b/html5/thumbnails/28.jpg)
So What, and Who Cares?
Students and Techs are challenged both physically and mentally by the microbial world. In this world of newly found, life-threatening diseases, education has become the key to survival. Health care providers must be committed to infection control so that diseases can be conquered!

reactions
• Non-Ionic Contrast– Less patient allergic
reactions
