Oxygenation Dynamics Flashcards
What is normal minute ventilation Range?
4-8 L/min (5L/min Average)
What is normal Cardiac Output (CO)?
4-8 L/min (5.5L/min Average)
What is Q?
Abbreviation for Cardiac Output
What is venous admixture V/Q mismatch?
Lack of available oxygen to the alveolar membrane
What is Shunting?
Any type of block that inhibits gas exchange “A Shunt is where blood flows past alveoli with no gas exchange occurring”
What is the first stage of shock?
Uncompensated Respiratory Alkalosis
What is deadspace ventilation?
Lack of perfusion to part of the lung tissue which is being ventilated. ie: pulmonary embolism, cardiogenic shock, etc.
What is first line therapy for venous admixture?
Supplemental Oxygen Therapy
What are the goals of Aerobic Respiration?
Production of ATP
What is required for aerobic respiration (4 things)?
Adequate Oxygen
Ability to extract O2 and move into the cell (hemoglobin)
Ability to move oxygen (Cardiac Output)
Ability to move O2 into the cell
What is the normal amount of hemoglobin in an adult?
12-15g/dl
Which patients have lower glycogen stores?
Pediatrics and Geriatrics
What is Glycoloysis?
The first stage of ATP creation, converts glucose to pyruvate
What is Lactate?
Product of glycolysis,
Indication of stress (a need for more ATP), not a direct indication of tissue hypoxia
What are the end products of the Krebs Cycle?
2 ATP
6 CO2
6 NADH
2 FADH
