The tank is too low
|
Blood loss
Severe dehydration Significant anemia HYPOVOLEMIC SHOCK |
|
A bigger tank
|
Vasodilatation
Hyperthermia Capillary leakage Increased metabolism SEPTIC SHOCK |
|
The filter pump is weak
|
Can’t move the water through the filter
Can’t move enough water to clean the whole tank Can’t get oxygenated water to the fish hiding in the corner CARDIOGENIC SHOCK |
|
Clinical findings of shock
|
Organs begin to fail
oliguria hypoxia “peripheral hypothermia” mental changes hepatic function decrease/labs cardiac strain |
|
measurements
|
HR; heart rate
BP; blood pressure MAP; mean arterial pressure SV; stroke volume CO/CI; cardiac output/index CVP; central venous pressure PCWP; pulmonary capillary wedge pressure SVR; systemic vascular resistance LVSW/I; left ventricular stroke work/index |
|
MAP=
SVR= LVSW= |
MAP= 2(dBP) + sBP / 3
SVR= MAP – CVP x 80 / CO LVSW= (MAP – PAD) SV x 0.0136 |
|
most common - Measure cardiac output
|
Dilutional
A given volume at a given temp, added to a second given volume at a known temp, will change temp a known measure |
|
difficult - Measure cardiac output
|
Photometric
|
|
what is relative CO in hypovolemic vs septic shock?
|
hypovolemic CO is down
septic shock, CO is up |
