Push-To-Set suction regulators recommend intermittent suction for nasogastric drainage, and continuous suction for tracheal, pharyngeal, surgical suctioning or chest drainage. The digital gauge unit for adults offers both intermittent and continuous suction modes to meet your clinical needs. The "Push to Set" feature eliminates the need to occlude patient tubing to set accurate vacuum levels. The "Quick-To-Max" feature requires only 1-2 turns to reach full wall vacuum for emergency resuscitation.
