Are the PhysioSuite MouseSTAT Pulse Oximeter Sensors CT compatible?

Yes.

Can I output data?

Yes, you can have one analog output or output all parameters digitally.

Can the MouseSTAT measure SpO2 on 7-day-old mice?

Yes, you can use the 4 mm paw sensor or try using the Y-Clip sensor as a whole body sensor.

Can the MouseSTAT Pulse Oximeter be used on awake animals?

Yes, the MouseSTAT Pulse Oximeter and sensors measure pulse oximetry on awake, immobile or anesthetized animals with heart rates up to 900bpm.

Scientists in search of equipment to meet their study needs should be aware that there are legitimate questions regarding even the possibility of taking these measurements in mobile animals. In reality, there is currently no system capable of 100% reliably measuring pulse ox in active, conscious animals.

The reasons for this are many. First, the sensor must be considered. Systems using neck or throat-fitted optical sensors rely on them being affixed to the animal at the prescribed region while tethered by a cable to the monitor’s controller. The stress of initially applying the sensor in either of these areas causes variations in heart rate and pulse oxygenation and make natural readings unobtainable. Once acclimated to wearing them, the animal must adapt to essentially being at the end of a leash, again, an unnatural condition resulting in skewed readings.

Arguably, placing a conscious animal in an individual animal holder, pacifying and acclimating it to the environment and applying an unobtrusive sensor to its paw is far less disruptive to their normal conditions, and more conducive to acquiring readings that can be relied on.

Remember, any method of restraining your animal will affect the data you’re able to collect. Minimizing the stress of the procedure, reducing the duration of the monitoring period and accelerating how quickly the animal is able to adapt all can have an impact in acquiring more reliable, reproducible readings.

Can the MouseSTAT settings be manually set?

Yes. You can choose from either a manual setting or allow the MouseSTAT to automatically set your respiratory rate and tidal volume.

To use the automatic setting, enter the animal's weight and press run.

To manually set-up the ventilator, adjust the settings within the configuration menu, see the User's Guide for additional details.

How does the RoVent operate in both constant volume and constant pressure modes?

The RoVent operates in either a constant pressure or a constant volume mode. When in the constant pressure mode it will report the tidal volume delivered. When in the constant volume mode it will report the airway pressure generated to deliver the volume and functions like a standard volume ventilator.

For animal safety the volume mode has both minimum and maximum pressure settings. Regardless of the volume delivered, a minimum airway pressure has to be attained so the animal will be ventilated at a minimal level. Also, regardless of the inspiratory volume, the airway pressure will not go over the maximum pressure setting, thereby protecting the animal from over ventilation. Minimum and maximum pressure are set by the user.

What can I use to clean the controller?

Standard lab disinfectants should be used to clean and disinfect the controller.

How can I upload data to my computer from the PhysioSuite, CODA Monitor or SomnoSuite?

Are the PhysioSuite MouseSTAT Pulse Oximeter Sensors CT Compatible?

Yes.

Can I connect an anesthesia mask to my PhysioSuite RoVent?

No, the PhysioSuite RoVent is not designed to ventilate animals using a nose cone. In order to use the PhysioSuite RoVent, the animal must be intubated or tracheotomized.

How thick are the far infrared warming pads?

0.25 inches.

Interested in a complete physiological monitoring set-up?

Your physiological monitoring set-up is dependent on your research protocol. To help you identify what you will need, please fill out our Sales Support form.

Is the PhysioSuite compatible with my stereotaxic system?

Yes, the PhysioSuite is compatible with stereotaxic systems. Please contact Kent Scientific with the model of your Stereotaxic Gas Anesthesia Mask, and we will be happy to provide compatible tubing for you.

What can I use to clean the warming pads?

They can be cleaned using a germicidal or antiseptic soap with warm water. It is recommended that you use a surgical sheet or some other layer between the pad and the animal. This helps to maintain a sterile environment (if necessary) and also aids in the clean-up after the procedure. Because the pads use far infrared heat, there is no concern about the additional layer inhibiting the animal from being warmed properly.

What material are the warming pads?

The pads are made of water-resistant nylon and are flexible enough to wrap the animal if necessary.

Why do we recommend to intubate?

When using the PhysioSuite MouseSTAT, the animal must be intubated or tracheotomized. Nose cones and face masks are not compatible with the PhysioSuite MouseSTAT.
