|
Term
| What are some conditions that occur after burn airway injury? |
|
Definition
1) Copious, thick secretions promote airway obstruction
2) large fluid shifts from aggressive IVF increase airway compromise

|
Definition
1) bronchoscopy
2) CXR
3) ABGs

|
Term
What is the 1/2 life of CO?

|
Definition
|
|
Term
| What happens on the cellular level with cyanide toxicity? |
|
Definition
cyanide is rapidly absorbed and:
inhibits mitochodrial enzyme (cytochrome oxidase, if you want to know) and blocks the ETC
-this decreases/stops ATP output and cellular pump control
-cell hypoxia/death |
