The Pulmonetic LTV 1000 is a new respiratory patient-ventilator that works with both hi-pressure and low pressure/low flow oxygen sources. The LTV 1000 is about the size of a laptop computer (12.6 lbs / 5.7 kg) and has a one-button operation. It is designed for use with adults, pediatricians, and neonatal patients. The large, color-coded displays easily convey data to the clinician. A comprehensive alarm package is a standard feature. The LTV-1000 is portable and piston-driven — no compressor needed.
