FAQs

What are the costs associated with the use of PhysioFlow®?
PhysioFlow® is a reasonably priced capital equipment that uses inexpensive disposable sensors. Please contact Nissha Medical Technologies at 800-669-6905 or HS.Info@nisshamedical.com

Does PhysioFlow® monitor ICU patient's fluids status?
Unlike the pulmonary capillary wedge pressure measured indirectly by a PA catheter, PhysioFlow® directly evaluates and/or trends parameters related to the filling: preload ratio, thoracic fluid index, end diastolic volume, and soon stroke volume variation.

Does PhysioFlow® require specific skills to be operated?
No, provided that the operator has basic knowledge of MS-Windows™ operating system. PhysioFlow® software has been designed to offer optimal user friendliness.

Do you have a software version for Apple computers or iPhone™?
Not at the present time, but development is underway.

Are there risks to the patient?
The emitted signal is of very low magnitude (3.6 mA peak to peak), safe and not felt by the patient. PhysioFlow® can be safely used on children and pregnant women as well. 

Is there extensive patient preparation involved?
No, during routine evaluations only shaving and light skin abrasion (using the NuPrep™ gel) is required. For exercise testing taping the lead wires is recommended and surgical fishnet should be used to cover electrodes and leads in case of running.

Are there limitations or contraindications of the system?
Severe aortic valve insufficiency results in an overestimation of Stroke Volume and Cardiac Output. PhysioFlow® has not been validated in case of severe heart malformation or in children below 25 kg.

Can PhysioFlow® be used during surgery?
Yes, except during open chest surgery. Please note the signals will be lost during the use of electrosurgical instruments but will recover immediately thereafter.
