Study Notes
Airway Management
- An oropharyngeal airway prevents tongue obstruction of the upper airway.
- Suctioning is indicated when there are signs of inadequate airway clearance.
Intubation and Ventilation
- Intubation attempts should be limited to a recommended maximum of three attempts to minimize complications.
- Positive End-Expiratory Pressure (PEEP) in mechanical ventilation improves oxygenation by preventing alveolar collapse at the end of expiration.
- Peak pressure limit during mechanical ventilation is typically set to avoid lung injury and should be monitored continuously.
Noninvasive Mechanical Ventilation
- Main advantage: Noninvasive mechanical ventilation reduces the need for intubation and may improve patient comfort.
- Potential disadvantages include risk of skin breakdown and inadequate ventilation if mask does not fit properly.
- Contraindications for noninvasive mechanical ventilation include respiratory arrest and severe facial trauma.
Weaning Process
- Weaning from ventilator support aims to gradually reduce dependence on mechanical ventilation while ensuring patient stability.
- The first step in weaning involves assessing readiness criteria, such as adequate spontaneous breathing and hemodynamic stability.
- The final step in weaning is extubation, which requires careful monitoring post-removal.
Indications and Contraindications
- Signs of respiratory muscle fatigue include increased work of breathing and altered mental status.
- A bag/valve mask is essential at the bedside for immediate ventilation assistance if needed.
- Contraindications for spontaneous breathing trials (SBT) include ongoing sedation and severe respiratory distress.
Oxygen Management
- Recommended FiO2 limit for initiating noninvasive mechanical ventilation is usually set around 0.40-0.50, requiring reevaluation based on patient response.
Ventilation Modes
- Continuous Positive Airway Pressure (CPAP) mode maintains continuous pressure support, which may enhance functional residual capacity.
- Automated pressure support is provided in modes similar to Pressure Support Ventilation (PSV) when patient initiates breaths.
- During weaning under PSV or CPAP, goal respiratory rate is set between 8-30 breaths per minute.
Monitoring During the Process
- Early signs of failure during weaning may include increased respiratory rate, tachycardia, and increased work of breathing.
- An observation period of at least 30-60 minutes is recommended after transitioning to PSV or CPAP to monitor for early failure signs.
- Initial drive pressure in PSV during the weaning process is generally started low, around 5-10 cm H2O, and adjusted based on patient response.
Extubation Considerations
- Potential indications for extubation include successful weaning trials and stable respiratory parameters.
- Medications that may depress respiratory function should be held for several hours prior to extubation.
