High frequency ventilator is an automatic mechanical device designed to provide all or part of the work the body must produce to move gas into and out of the lungs. It is used to produce high frequency, low amplitude breaths. These are generally used on patients with respiratory distress syndrome. These are also on patients that have lungs that leak air.
High frequency VOR test equipment is designed to provide information about the vestibular ocular reflex in patients with dizziness or balance problems. It offers researchers and clinicians a simple and inexpensive method to evaluate VOR gain, phase and symmetry. It utilizes a headband mounted angular velocity sensor. This patented solid-state sensor produces an electronic waveform that is proportional to head angular velocity.
