Study Notes
Airway Management
-
Unconscious Patient Airway Opening:
- Head Tilt Chin Lift: Use if no suspected neck/spine injury.
- Jaw Thrust: Use if suspected neck/spine injury.
-
Airway Suctioning Complications:
- Prolonged suctioning (>15 seconds) can cause hypoxia, potentially leading to death.
Airway Adjuncts
-
Oropharyngeal Airway (OPA):
- Insertion Method:
- Size by measuring from the center of the mouth to the angle of the jaw or from the corner of the mouth to the earlobe.
- Open mouth with cross-finger technique.
- Insert with tip toward the roof of the mouth.
- Rotate 180 degrees; the flange should rest against the mouth.
- Do not use on conscious patients or those with gag reflexes.
- Insertion Method:
-
Nasopharyngeal Airway (NPA):
- Insertion Method:
- Size by measuring from the nostril to the earlobe or jaw angle.
- Use water-based lubricant.
- Gently push the nose upward and insert the airway with the beveled side toward the base of the nostril or septum.
- Advance until the flange rests against the nostril.
- Never force insertion.
- If unsuccessful, try the other nostril.
- Contraindication: Suspected head or facial injury.
- Insertion Method:
Oxygen Delivery Devices
-
Nasal Cannula:
- Use when mask isn't tolerated.
- Flow rate: 1-6 liters per minute.
-
Non-Rebreather Mask:
- Preferred for hypoxia, shortness of breath, chest pain, severe injury, or altered mental status.
- Flow rate: 12-15 liters per minute.
-
Bag-Valve-Mask (BVM):
- Use for non-breathing patients or those with inadequate respirations.
- Flow rate: 15 liters per minute.
-
Tracheostomy Mask:
- Use for patients with stomas.
- Flow rate: 8-10 liters per minute.
Oxygen Cylinder Information
-
Oxygen Cylinder Sizes:
- D: 350 liters
- E: 625 liters
- M: 3,000 liters
-
Oxygen Regulator Purpose:
- Lowers high cylinder pressure (too high for patient delivery) to a safe range of 30-70 psi.
Other Respiratory Devices
-
Continuous Positive Airway Pressure (CPAP):
- Used for pulmonary edema, drowning, asthma, and COPD.
