A trach collar is a device used to deliver humidified oxygen to a patient with a tracheostomy, providing supplemental oxygen and aiding in airway clearance. In contrast, a ventilator is a machine that provides mechanical ventilation, assisting or fully controlling a patient's breathing by delivering air directly into the lungs. While a trach collar is used for patients who can breathe independently but need additional oxygen, a ventilator is used for patients who cannot breathe adequately on their own.
