How do you measure fluid balance and how many lbs of weight gain in a day is concerning?

I/O daily weight- most accurate >3 lb/day is concerning

ventilation

the process of moving gases into and out of the lungs. it requires the muscular and elastic properties of the lungs and thorax to be coordinated

perfusion

the cardiovascular system must have the ability to pump oxygenated blood to the tissues and then return it to the lungs

what is central sensitization? Hyperalgesia? Allodynia? what do these types of pain have in common?

CNS becomes sensitized resulting in patient becomes more sensitive to pain so person will respond hyperalgesia- increased response to a stimulus that is ordinary painful allodynia- pain when no painful stimulus less responsive to opioid analgesia and often result in escalation of opioid dosing with a higher risk of side effects These types of pain are less responsive to opioid analgesia

acute pain
