Modified ventilator with liquid-oxygen system for transport of adult patients with acute respiratory failure

The value of modern techniques of respiratory care for patients with acute respiratory failure in specialized intensive care units has been documented. Unfortunately, many patients needing this type of care are located far from such resources and require transportation over large distances. This paper describes a modified bird Mark 14 ventilator and a Linde liquid oxygen attachment used successfully in the air and ground transport of 84 patients over a five-year period.
