ACID BASE Flashcards
Rule of B’s
If pH and Bicarb both move in same direction than the acid-base imbalance is metabolic. If not, its respiratory.
When pH is high?
Everything goes up except potassium
When pH is low
Everything goes down except for potassium
Alkalosis signs and symptoms pH of over 7.45
Everything is up
- borygimi, hyperrelexia, irritability, seizure, spastic, diarrhea, tachycardia, tachypnea, HTN
Acidosis signs and symptoms
Everything goes down except for K:
- slow gastric motility, hyporeflexia, bradycardia, bradypnea, constipation, hypotension
“MAC Kussmaul”
is the only acid base to cause metabolic acidosis
If the imbalance is caused by lungs
Its respiratory
If the imbalance is caused by
prolonged gastric suctioning/vomiting
Its metabolic alkalosis
Everything else not caused by lungs or gastric suction/vomiting
Its metabolic acidosis
If pH is under 7.35 is it undervent or overventilation?
underventilation
If pH is over 7.45 is it under or over ventilation?
Overventilation
High pressure Alarms triggerd by
increased resistance to air flow -> look for obstructions
Order to address High pressure Alarm issues
1st. unkink
2nd. Check for condensed H20 and empty it
3rd: have patient deep breath and cough
4th: Suction
Low pressure alarms are triggered by
decreases in resistance to air
THINK Disconnection!
Actions for Low pressure alarm
- Maintubing or O2 Sensor tubing disconnection -> reconnect
- Bag pt and call RT
