HARVARD ADVANCED SAFETY VENTILATOR INSPIRA ASV, CATALOG NO. 55-7058 Harvard Apparatus Advanced Safety Ventilator Volume Controlled Model Inspira ASV Catalog Number 55-7058 Manufacturers Description: The Inspira is Harvardâs first ventilator that can ventilate animals from mice to cats using the same machine. Its versatility and ease of use allow safer and superior ventilation. The Inspira Ventilator uses an advanced piston/cylinder assembly and a microprocessor controlled actuation mechanism to precisely control respiration profiles. Two interchangeable piston/cylinder  assemblies are available to provide a wide range of tidal volumes. The ventilator auto-detects which cylinder, or if no cylinder, is installed. Variable flow valves control the gas flow for inhalation and exhalation. The Inspira ASV Volume Controlled Ventilator delivers the desired tidal volume to the animal by precisely controlling the stroke of the piston. Since actual stroke length (and therefore tidal volume) may be modified for a given stroke, sigh breaths are supported. Since stroke speed is precisely controllable during inspiration and expiration, variable inspiration-to-expiration ratios are also supported. A pressure sensor continuously monitors the airway pressure to prevent over-pressure conditions. Most volume-controlled ventilators presently available do not support sigh breaths and do not provide any pressure monitoring as a safety feature. The Inspira ASVp pressure-controlled ventilator adds pressure control capability to the ASVv volume-controlled platform. Inspiration pressure is limited to the user entered pressure setting. Flow rates are automatically adjusted by the microcontroller by changing the tidal volume while keeping the inspiration time constant. The flow rate is adjusted so that the inspiration pressure limit is reached near the end of the piston stroke, ensuring that animals with a higher airway resistance receive the majority of the expected tidal volume and that the ventilator does not prematurely terminate the piston stroke. No manual adjustment of inspiratory flow rates is required. The ASVp also adds PEEP capability for both the volume- and pressure-control modes. The machine allows a PEEP setting up to 10cmH2O.
