Hand hygiene01:23

Hand hygiene

4.7K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Handwashing I: Introduction and Types of Equipment

4.6K
Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated....

Handwashing II: Pre-procedure and Initial Procedure Steps

1.2K
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail...

Assessing Body Temperature - Oral

997
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Area of Science:

  • Food Safety
  • Computer Vision
  • Public Health

Background:

  • Foodborne illnesses are frequently caused by improper food handling.
  • Effective hand hygiene is a primary method for pathogen reduction in food preparation.
  • Automated monitoring systems can enhance hand hygiene compliance.

Purpose of the Study:

  • To design and evaluate a multi-camera video analytics system for recognizing hand-hygiene actions.
  • To improve the effectiveness and consistency of hand hygiene practices in food handling environments.
  • To reduce the incidence of foodborne illnesses through enhanced hygiene monitoring.

Main Methods:

  • Development of a two-stage video processing system using egocentric and third-person cameras.
  • Implementation of a coarse classifier for localizing hand-hygiene periods.
  • Utilization of refinement classifiers to recognize seven specific hand-hygiene actions.

Main Results:

  • The two-stage system significantly reduces computational requirements compared to processing untrimmed video.
  • Recognition accuracy is maintained despite lower computational load.
  • Refinement classifiers process less than 68% of the untrimmed video data.

Conclusions:

  • A well-designed video action recognition system can effectively monitor and improve hand hygiene.
  • This technology offers a promising approach to enhance food safety and prevent foodborne illnesses.
  • Further computational efficiencies are expected with videos containing fewer hygiene actions.
