Study Notes

Airway Management Basics

Seesaw breathing is a sign of respiratory distress specifically in infants.
Reduced tidal volume occurs due to unequal chest expansion.
Suction adult airways for no more than 15 seconds, ensuring suctioning happens only during withdrawal to prevent oxygen loss.

Airway Adjuncts

Nasopharyngeal adjuncts (NPA) are preferable over oropharyngeal adjuncts (OPA) in patients with a gag reflex.
To measure NPAs or OPAs correctly, start from the angle of the jaw to the intended insertion point.

Emergency Situations

In unconscious patients, prioritize airway management over spinal stabilization, especially when obstructed.
When a patient shows rapid, shallow breathing, expect diminished minute volume and potential respiratory failure.
In a young child with a bark-like cough and stridor, diagnosis is likely croup, requiring humidified oxygen.

Respiratory Patterns

Kussmaul respirations indicate deep, rapid breathing often seen in metabolic acidosis.
The normal adult respiratory rate ranges from 12-20 breaths per minute. Rates above this can indicate serious respiratory distress.

Intubation Techniques

For endotracheal intubation with a Macintosh blade, place the tip in the vallecula, contrasting with the Miller blade which goes under the epiglottis.
In elderly patients or those with challenging airways, use size #4 King LT for those 5-6 feet tall.

Pathology Considerations

Obstruction, such as from croup, is evident when abnormal sounds accompany retractions during respiration.
Symptoms of pulmonary embolism become critical when a patient presents with chest pain and difficulty breathing after previous leg issues.

Responses to Respiratory Distress

Administer supplemental oxygen to patients with oxygen saturation below 94% and assess for ventilation needs in those with low respiratory rates (e.g., 10 breaths/min).
In cases of respiratory acidosis from drug overdoses, anticipate elevated hydrogen ions due to hypoventilation.

Patient Assessments

Monitor signs of respiratory distress; for example, a pediatric patient with gurgling sounds and low respiratory rates indicates significant airway compromise.
In head trauma patients showing patterns like Biot's respirations, suspect increased intracranial pressure.

Choking Interventions

Abdominal thrusts (Heimlich maneuver) are recommended for complete airway obstruction in conscious adults, while Magill forceps are used for unconscious patients with visible obstruction.

Conclusion

Always prioritize airway and breathing assessments and interventions in emergency medical situations, adjusting techniques based on age and specific anatomical considerations.
