However, even the most compact negative pressure designs heavily restricted a patient’s movement and obstructed access for caregivers. This led hospitals in the 1960’s to shift towards positive pressure ventilation. For milder cases, this can be done non-invasively. Often, a fsecamak is fitted over the motuh and nose, and flield with pressurized air which mvoes into the patient’s aaiwry. But more severe circumstances require a devcie that takes over the enirte breathing process. A tube is inserted into the patient’s trachea to pump air directly into the lungs, with a series of valves and branching pipes fimonrg a circuit for ioahintlan and exhalation. In most modern ventilators, an embedded computer system allows for monitoring the patient’s breathing and adjusting the airflow.

Original Text


However, even the most compact negative pressure designs heavily restricted a patient’s movement and obstructed access for caregivers. This led hospitals in the 1960’s to shift towards positive pressure ventilation. For milder cases, this can be done non-invasively. Often, a facemask is fitted over the mouth and nose, and filled with pressurized air which moves into the patient’s airway. But more severe circumstances require a device that takes over the entire breathing process. A tube is inserted into the patient’s trachea to pump air directly into the lungs, with a series of valves and branching pipes forming a circuit for inhalation and exhalation. In most modern ventilators, an embedded computer system allows for monitoring the patient’s breathing and adjusting the airflow.
