    Study Notes

    Oral Care in Intubated Patients

    • Recommended methods include using a soft toothbrush and hydrating oral mucosa to prevent dryness.
    • Frequency of oral care should be every 2-4 hours to reduce the risk of ventilator-associated pneumonia.

    Suctioning Guidelines

    • Maximum duration for withdrawal of the suction catheter is 10-15 seconds to minimize hypoxemia.
    • Maximum suction pressure should not exceed 120 mmHg to avoid trauma to the airway.
    • External diameter size for the suction catheter should be no more than 15% of the endotracheal tube diameter to ensure effective suctioning without obstruction.

    Indications and Contraindications for Suctioning

    • Indications for suctioning include visible secretions in the airway and decreased breath sounds.
    • Contraindications include the presence of a severe airway obstruction and significant cardiac arrhythmias.

    Ventilation Parameters

    • Recommended range for respiratory rate on a ventilator is 12-20 breaths per minute to ensure adequate ventilation.
    • Oxygen concentration (FIO2) on a ventilator should ideally be kept between 21-100% based on patient's oxygen needs.

    Mechanical Ventilation Modes

    • Assist-Control (AC) mode adjusts for resistance of non-flexible tubing, providing consistent support for the patient.
    • Pressure Support Ventilation (PSV) can also adapt as it offers preset pressure levels during spontaneous breaths.

    Complications Associated with Endotracheal Tubes

    • Potential complications include ventilator-associated pneumonia, airway obstruction, and tracheal injury.
    • Regular assessment and monitoring are critical to minimize these risks.

    General Precautions

    • During suctioning, avoid extended periods of suction to prevent hypoxemia and lower airway colonization.
