Small animal veterinary anesthesia workstation WATO A7

tabletop

Overview
WATO A7 is a veterinary anesthesia system presented with the tagline 'Beyond Definition'. It is engineered to deliver comprehensive ventilation, integrated gas management and veterinarian-oriented workflows for precise and safe perioperative anesthesia management.

Key Features

• Turbine-driven ventilator: high-performance turbine provides reliable ventilation without the need for a high-pressure driving gas.
• Internal air supply: built-in air pump supplies medical-grade fresh gas with ultra-quiet operation <45 dB.
• Status screen: 5.5-inch color display showing tidal volume, airway pressure and gas supply pressure.
• Comprehensive ventilation: minimum tidal volume down to 5 ml across all volume modes; ACGO pressure monitoring for accurate control.
• APRV (Airway Pressure Release Ventilation): incorporates a short expiratory phase to increase venous return and cardiac output, improve CO2 elimination and reduce expiratory airway collapse.

Enhanced Functions

• Monitored mechanical parameters:
  
  • Driving Pressure: monitors lung distensibility and informs ventilation strategy.
  • Mechanical Power: supports precise assessment of perioperative lung stress and risk.
• Flow Pause: suspends fresh gas output and ventilation when the patient is temporarily disconnected (e.g., during position changes).
• Insp & Exp Hold Tools: stores the last four measurements for review.

Visible Safety

• Electronic flow meter: digital gas mixer for precise and intuitive fresh gas flow settings with clear high-flow and low-flow indicators.
• Optimizer™: automatically recommends minimum fresh gas flow to reduce costs and environmental impact.
• Real-time anesthetic agent measurement: instant monitoring of anesthetic consumption using advanced calculation software.

Spirometry & Lung Management

• Spirometry: rapid display of changes in compliance, atelectasis and overdistension.
• Visible lung recruitment: stepwise PEEP recruitment manoeuvre with integrated outcome evaluation tools.
• Recruitment procedure features:
  
  • Stepwise PEEP recruitment manoeuvre
  • Up to 5 preset procedures
  • Customizable labels
  • Up to 7 steps per procedure
  • Outcome evaluation tools

Designed Around Veterinarians

• Veterinary-specific workflow including an end-to-end customizable perioperative checklist for inspection and preparation.
• Smart ventilator settings: enter the animal's weight and ventilator parameters are set automatically.
• Safety-driven alarm limits: alarm thresholds adapt to patient size to help prevent barotrauma.
• Accurate respiratory monitoring: RR monitoring auto-selects the most reliable signal to reduce false alarms.
• Tailor-made workflows: customizable screen layout, profiles and settings to fit clinical practice.

Connectivity & Management

• AnaePilot: smart connectivity solution enabling WATO A7 to interface with infusion pumps and monitors for synchronized control and device management.
• VetiNet CMS compatibility: centralised case monitoring, automatic recording of real-time anesthesia data and generation of electronic anesthesia records.
