Background and Identification

The Puritan Bennett Achieva ventilator provides support for pediatric to adult patients with respiratory inefficiencies or failures . The device is used in hospitals, homes, and in portable settings. The positive pressure ventilation can be delivered invasively or noninvasively. The Puritan Bennett Achieva has a wide range of breath rates, delivery volumes, and inspiratory times. This model has a flow acceleration limit and expiratory sensitivity feature to fine-tune the breath delivery rate. This device also has internet dial-in PEEP with flow and pressure trigger sensitivity to help with patient synchrony. The Puritan Bennett Acheiva has three different model types, PS, PSO2, and PSX. This ventilator is predominantly bought by long-term acute care facilities and homecare respiratory companies.

The Puritan Bennett Achieva is manufactured by Nellcor Puritan Bennett. Puritan Bennett began producing respiratory products in 1913. Puritan Bennett also makes oxygen therapy systems, sleep therapy equipment, and other respiratory care products. However, the Puritan Bennett Ventilators are the most widely known, there are many different series and systems.

The Puritan Bennet Achieva has a compact design and a magnetic latched door panel on the front. This device has a portable oxygen and power source. The device has a light grey body with blue accents and the name PURITAN-BENNETT Achieva on the latched door panel. The dimensions are as follows:
