    Trach Tomas — Tracheostomy & Suctioning Safety: Oxygenate First, Suction Out Only

    His secretions are thick, his saturation is dropping, and the safest suction is the shortest one

    Trach Tomas, the MnemoNurse character for Tracheostomy & Suctioning Safety: Oxygenate First, Suction Out Only

    Tomas's breathing turns gurgly and his oxygen saturation slips to 88%. The nurse reaches for suction — and follows every step in order.

    Tomas breathes through a tracheostomy. Suctioning clears secretions but also removes oxygen, so the rules protect against hypoxia: hyperoxygenate first, use sterile technique, insert WITHOUT suction, apply intermittent suction only while withdrawing, limit each pass to about 10 seconds, and allow rest between passes. Suction only when indicated — noisy wet breathing, visible secretions, desaturation — not on a fixed schedule. Keep an obturator and a spare tracheostomy tube of the same size at the bedside. If the tube is dislodged, hold the stoma open and call for help immediately; if it is obstructed, suction, and if that fails, this is an emergency.

    The story arc

    1. The setup

      After prolonged ventilation, Tomas receives a tracheostomy and is learning to live with it.

    2. The turn

      His breathing becomes wet and rattly, and his saturation drifts down.

    3. The crisis

      Mid-suction his saturation falls further and his heart rate drops. The nurse withdraws the catheter and re-oxygenates.

    4. The save

      Tomas is hyperoxygenated, suctioned only on withdrawal, allowed to rest, and his stoma care is done with a spare tube ready at the bedside.
