### action | improvement | ventilation:

Good ventilation
* can reduce the number of droplets in the air.
* helps to keep barns dry.
* is essential to the rapid removal of water vapor.
* is important for the foal's respiratory health, but drafts are undesirable
  - in preventing the build-up of biological particles
  - to create air movement for gas dispersal
  - probably the most important factor in keeping indoor pens dry
  - very important in ensuring that cattle houses are kept as dry as possible
* reduces indoor air pollution.
* suppresses black spot by promoting rapid drying of rose leaves.

Improper ventilation
* can lead to asphyxiation.
* creates moisture and heat buildup due to the lack of air movement.

Inadequate ventilation
* can create health hazards and destroy equipment.
* makes indoor cooking with charcoal dangerous.

### action | improvement | ventilation:

Mechanical ventilation
* can present several problems when caring for a patient
  - supply that air at the correct rate whenever it is required
* essential supportive therapy for patients with acute lung injury.
* is explained as it relates to the physiologic considerations of asthma.
* is required to eliminate dust
  - when isocyanates are heated
* is the fundamental technique for life support in the intensive care setting
  - main supportive therapy for treatment of severe botulism
* is used to keep a person breathing in extreme cases
  - support or replace the function of the lungs
* keeps the level of oxygen at life-sustaining levels.
* method to mechanically assist or replace spontaneous breathing.

### action | improvement | ventilation:

Natural ventilation
* can considerably reduce the cooling needed for comfort during much of the year
  - reduce cooling needs and add to human comfort
* is more successful in moderate climates than in extremely hot or cold climates.
* is used during spring and autumn to reduce energy consumption
  - instead of mechanical cooling
* makes air conditioning unnecessary even in summer.
* performs one basic function - supplying fresh air.
* removes hot air from a space.
* works best when vents are near the floor and ceiling
  - better in Hawaii than on the mainland due to powerful trade winds
  - more effectively with curtains on the sidewall than with shutters

Poor ventilation
* can be detrimental to animal health and performance.
* can lead to moisture and indoor pollutant accumulation
  - respiratory illness
  - result in high atmospheric humidity and ammonia levels
* causes about half of the indoor air pollution problems.
* is one of the primary causes of breathing problems in snakes
  - the biggest cause in bathrooms
* leads to carbon monoxide poisoning and eventual death by suffocation.

### action | improvement | ventilation:

Proper ventilation
* can also control condensation
  - help to lower the concentration of pet allergens
  - prevent chemicals from affecting other materials in storage
* helps keep litter dry by removing excess moisture
  - maintain livestock health during hot and humid weather
  - prevent carbon monoxide from building up in the home
* is essential to indoor air quality
  - important in reducing biological risks
* is necessary to control odors and reduce the spread of respiratory diseases
  - prevent oxygen starvation
* offers protection from biological hazards, explosions, and toxic gases.
* plays an important role in herd health.
* reduces the risk of carbon monoxide poisoning.

Incision
* Most incisions are part of sterilization.
* are cuts
  - depressions
  - laceration
  - made through the skin of the ankle where the bones are broken
* are part of operations
  - places around the nipple, under the breast or in the armpit
* is made through abdomen into womb.
* leave two small, hairline scars that are barely visible when healed.
* made on the outside of the lower eyelids are barely visible and the scars fade over time.
