Mark K Lecture 1 Flashcards
What does ROME stand for?
ROME stands for Respiratory Opposite, Metabolic Equal.
What do we look at to determine acid-base status from an ABG?
Normal pH and normal HCO3.
What is the normal pH range?
7.35-7.45.
What does it mean if pH goes DOWN?
This indicates acidosis, so the patient’s signs and symptoms will go down.
What happens to potassium levels during acidosis?
Potassium goes up.
What are some signs and symptoms of hypokalemia?
Tachycardia, diarrhea, +3, +4 reflexes, hypertension, seizures, irritability, borborygmi.
What are some signs and symptoms of hyperkalemia?
Hyporeflexia, bradycardia, lethargy, obtunded, paralytic ileus, coma, respiratory arrest.
When do you see Kussmaul breathing?
With metabolic acidosis.
If the lung is causing an acid-base imbalance, what type is it?
It is respiratory.
What does over-venting cause?
Alkalosis.
What does under-venting cause?
Acidosis.
What causes a low pressure alarm in vents?
Disconnection of tubing or low airflow.
How do you fix a kink in the ventilator tubing?
Unkink it.
What should you do if there is water in the ventilator tube?
Empty the tube.
What should you do if there is mucous in the airway?
Cough/deep breathe, suction as needed but do not over-suction.
What causes a high pressure alarm in vents?
Increased resistance to airflow.
What are the three types of ventilator obstructions?
Kink, water in tube, mucous in airway.
What should you do if there is disconnected tubing?
Reconnect it.
What should you do if the oxygen sensor tube is disconnected?
Reconnect it unless it was on the floor; if on the floor, bag it and call R1.
