# Airways Management & Lungs

***

Airway management is a critical first step in casualty care. An occluded or obstructed airway will lead to rapid oxygen desaturation (SpO2 drop) and eventual cardiac arrest.

## 🩺 Airways Management

|     Status     | Treatment                                                                | Sidenotes                                                                        |
| :------------: | ------------------------------------------------------------------------ | -------------------------------------------------------------------------------- |
|  **Occluded**  | <ul><li>Accuvac</li><li>Head Turning</li><li>Recovery Position</li></ul> | Perform until successful.                                                        |
| **Obstructed** | <ul><li>Head Hyperextending</li><li>Recovery Position</li></ul>          | Stay close to the patient while performing head hyperextending.                  |
|    **Clear**   | <ul><li>Guedel Tube</li><li>King LT</li><li>Recovery Position</li></ul>  | Use one of the ways mentioned to maximize the chance of airways remaining clear. |

## 🩺 Recovery Position

The recovery position prevents occlusions and obstructions from happening and clears the airway, but makes certain medical actions unavailable until the recovery position is canceled.

### Conditions for the action to appear (Unconscious Patient):

* Not in recovery position
* No Guedel Tube applied
* No King LT applied
* Not in a vehicle
* Not on a stretcher / stretcher slot

### Actions that cancel the recovery position:

* Carrying the patient
* Dragging the patient
* Putting the patient into a vehicle

### Medical actions/items blocked by the recovery position:

* Guedel Tube / King LT placement
* Accuvac suction
* Chest Seal / AAT Kit application
* Head Turning / Overstretching
* AED application
* CPR / Chest Compressions
* FAST IO chest insertion

## 🩺 Cyanosis (Visual SpO2 Estimation)

Checking cyanosis is a visual way of estimating a patient's oxygen saturation (SpO2) without medical equipment. It can be checked on arms (without active tourniquets) or on the head. If enabled in settings, cyanosis levels will appear directly on the patient's injury list.

|        Status       | SpO2 level (Default Settings) |            Visual Indicator           |
| :-----------------: | :---------------------------: | :-----------------------------------: |
|   **No Cyanosis**   |           90% – 100%          |            Normal skin tone           |
| **Slight Cyanosis** |           75% – 89%           | Mild blueish tint around lips/fingers |
|  **Mild Cyanosis**  |           66% – 74%           |           Clear blueish tint          |
| **Severe Cyanosis** |            0% – 65%           |        Deep blue/grey skin tone       |
