Study Notes
Indications for Intubation
- Indications include respiratory failure, inadequate oxygenation, inability to protect the airway, and respiratory distress.
Purpose of Endotracheal Tubes (ETT)
- ETTs provide a secure airway for ventilation, facilitating oxygen delivery and removal of carbon dioxide.
- They prevent aspiration by keeping secretions away from the trachea.
Complications of Suctioning
- Possible complications include hypoxia, trauma to airway structures, arrhythmias, and infection.
- Can also lead to bronchospasm and increased intracranial pressure in susceptible patients.
Artificial Airways for Tongue Obstruction
- Common types of artificial airways include oropharyngeal airways and nasopharyngeal airways.
- A tracheostomy is NOT typically included in the category of artificial airways used specifically to prevent tongue obstruction.
Negative Pressure Ventilators
- Negative pressure ventilators operate by creating negative pressure around the thoracic cavity to assist in breathing.
- Common types include iron lungs and similar devices that encase the body and draw air in through chest expansion.
Technique for Airway Patency During Suctioning
- Utilize a technique called "deep suctioning" to maintain airway patency.
- It involves careful insertion and withdrawal of the suction catheter while providing continuous oxygenation.
Recommended Duration for Intubation Attempts
- Recommended duration for an intubation attempt should not exceed 30 seconds to minimize hypoxia and other complications.
Indications for Suctioning
- Indications include the presence of secretions obstructing the airway, inability to clear secretions independently, and respiratory distress indicators.
- Suctioning may also be indicated in patients with impaired cough reflex or abnormal breath sounds.
