| What can be indicators for the need of extra oxygen? | Increased cardiopulmonary workload, heart rate, blood pressure, and patients work of breathing. |
| A person can go without oxygen for how many minutes before irreversible brain damage? | 6 Minutes. |
| What 3 things must you have to deliver oxygen? | 1. Oxygen delivery device 2. Gas source 3. Means by which the two can be connected. |
| What 2 units are oxygen measured in? | Liter Per Minute(LPM) and Percent Concentration (%). |
| When transporting a patient with an oxygen cylinder what amount of delivered oxygen should the patient get? | The amount should match what the patient was receiving at his/her bedside. |
| CV lines were initially developed to administer what? | Chemotherapeutic drugs and Parenteral Nutrition. |
| What color is an Air Flowmeter? | Yellow. |
| A properly positioned endotracheal tube should be how? | The distal tip should be 1 or 2 inches (3-5cm) superior to the tracheal bifurcation (Carina). |

| What are Thoracostomy (intrapleural) tubes, more commonly called chest tubes are used for what? | To drain the intrapleural space and the mediastinum. |
| Which part high or low allows us to guarantee the amount of oxygen the patient is receiving? | High flow. |
| What are CV lines also used for today? | To administer a variety of drugs, manage fluid volume, serve as a conduit for blood analysis and transfusions, and monitor cardiac pressures. |
| What masks are high flow? | Venturi, Aerosol, Trach, and Face Tent. |

| What is Hypoxemia? | The decreased partial pressure amount of oxygen present in the human blood. |
| What is Human Homeostasis? | Is the body's ability to physiologically regulate its inner environment to ensure its stability in response to fluctuations in the outside environment. |
| What color is an Oxygen Flowmeter? | Green. |
| What is a low flow? | Is a variable-oxygen concentration, a device that does not meet the entire inspiratory demand or needs of a patient. |
