The VentStar Small Animal Ventilator is an advanced mechanical ventilator engineered for precise respiratory support of laboratory animals weighing 10 g to 1 kg, including mice, rats, and guinea pigs. Ideal for medical research, preclinical trials, and veterinary procedures, the R415 provides safe, effective intermittent positive pressure ventilation (IPPV) with both volume control (VCV) and pressure control (PIPCV) modes. A touch-screen interface enables intuitive operation, fully customizable ventilation parameters (including animal weight input), real-time tracheal pressure curves, and intelligent safety alarms, optimizing reproducibility and animal care in experimental protocols.
