O2 Environmental Systems, CAM Tent, Infant O2 Hood, HBO

• Mist Tents (Croupette) or Cool Aerosol Mist (CAM) Tent


  Patient is placed inside a plastic canopy (tent), FiO2 = 40-60%, O2 flow = 8-15 L/min, temperature maintenance through refrigeration or freon use, seldom used for adults, humidity control by pneumatic nebulizer, set liter flow at least 8 L/min to ensure CO2 wash off
• Infant Hoods


  Transparent, hard plastic enclosure that surrounds the baby's head, gives supplemental oxygen by attaching APN or other O2 device, other body parts can be accessed by medical personnel, the opening is generally softly padded, available in various sizes, used for babies who can breathe on their own but still need extra oxygen

  
• Hyperbaric O2 therapy


  Administration of O2 at greater than normal atmospheric pressure, performed in specially designed chambers that permit the delivery of 100% O2 at atmospheric pressure that is 3X normal, used to overcome the natural limit of O2 solubility in the blood which is about 0.3ml O2/100ml of blood (PaO2 = 100 mmHg)
