MedExpert VET | Mindray Wato A7

Advanced Anesthesia Workstation Designed for Veterinary Surgery

The Mindray WATO A7 is an advanced veterinary inhalation anesthesia system designed for veterinary clinics and hospitals. The system combines a turbine ventilator, electronic gas-flow control, and advanced ventilation modes.

The WATO A7 can be considered the flagship of the Mindray Animal anesthesia equipment portfolio and represents a significant advancement over its predecessors, thanks to its turbine drive, integrated air supply, advanced respiratory mechanics monitoring, and integration with AnaePilot/VetiNet.

The turbine ventilator enables operation without high-pressure drive gas, while the built-in pump provides an independent supply of medical air. A minimum tidal volume of just 5 mL enables precise ventilation of small patients, while the range of up to 1500 mL allows ventilation to be adapted to animals of different sizes.

After the patient's body weight is entered, the Mindray WATO A7 automatically recommends appropriate ventilation parameters.

Applications

Veterinary inhalation anesthesia, general anesthesia, veterinary surgery, routine surgical procedures, orthopedic and abdominal procedures, prolonged surgical procedures, and advanced anesthesia procedures in animals of different body weights

Ventilation modes

Manual ventilation
Spontaneous breathing
VCV – Volume-Controlled Ventilation
PCV – Pressure-Controlled Ventilation
PCV-VG – Pressure-Controlled Ventilation with Guaranteed Tidal Volume
SIMV-VC/PC/VG – Synchronized Intermittent Mandatory Ventilation, volume-controlled / pressure-controlled / volume-guaranteed
CPAP/PS – Continuous Positive Airway Pressure with Pressure Support
APRV – Airway Pressure Release Ventilation: ventilation with controlled airway pressure release

Features

Turbine ventilator

the ventilator is driven by a high-performance turbine and does not require high-pressure drive gas for operation

Built-in air supply

an integrated pump provides medical air with a noise level below 45 dB

Ventilation settings

after the animal's body weight is entered, the system automatically recommends appropriate ventilation parameters

Patient-size-adaptive alarm limits

alarm limits are adjusted according to patient size to support safer ventilation and reduce the risk of barotrauma

Real-time anesthetic consumption measurement

monitors current and cumulative anesthetic consumption during the procedure

Spirometry

displays Pressure-Volume, Flow-Volume, and Pressure-Flow loops for assessment of respiratory mechanics

All features

Visually guided lung recruitment

visually guided lung recruitment with stepwise PEEP increases and assessment of the results

Flow pause

temporarily stops ventilation and fresh gas flow when the patient is disconnected from the breathing system

Inspiratory hold

enables measurement of plateau pressure, static compliance, and inspiratory resistance

Expiratory hold

enables measurement of intrinsic and total PEEP

Integrated heated breathing system

the heated breathing system reduces condensation formation

Veterinary-specific workflow

veterinary-adapted profiles, screen layouts, and settings for different clinical situations

End-to-end checklist

customizable checklists guide the user through system preparation and checks before and during anesthesia

Accurate respiratory rate monitoring

the system automatically selects the most reliable respiratory rate signal source

Key features

Advanced functions of inhalation anesthesia

Optimizer™

automatic fresh gas flow optimization; recommends the minimum required fresh gas flow to reduce gas consumption

APRV

an advanced ventilation mode with brief pressure-release phases that may improve alveolar recruitment, CO₂ elimination, and gas exchange

Electronic flowmeter

a digital gas-mixing system enables precise and intuitive adjustment of fresh gas flow

Mechanical power

provides additional assessment of the mechanical load imposed on the lungs during ventilation

Driving pressure

enables monitoring of the pressure difference associated with lung compliance and supports ventilation optimization

AnaePilot

connects the anesthesia workstation with compatible Mindray patient monitors and infusion pumps

VetiNet CMS

enables centralized monitoring of multiple devices, automatic data collection, and creation of an electronic anesthesia record
