Frequently Asked Questions
How did you come up with the idea?
Both Jason (Cardiology) and Andrew (Family & Emergency Medicine) regularly teach assessment of the JVP to medical students and residents. After years of watching students struggle with the two-ruler technique and seeing the high degree of variability on the wards, we decided to solve the challenge and develop an elegantly simple solution - One that you will be proud to own!
When will the device be available for purchase?
The JVPez is currently undergoing some final design modifications and clinical testing prior to being manufactured and ready for sales. It has been approved as a Class 1 device in Canada and willl be available in early 2020. Approvals in the US and EU are pending. Please let us know if you are living and practicing medicine outside of these jurisdictions and we will do our best to secure approval in your region.
Is the green light line harmful if accidentally projected into my patient's eye?
No, not at all. The green line line is actually generated using a light emitting diode or LED and transformed into a line using sophisticated optics. The JVPez does NOT use laser technology.
Any suggestions that will help me identify the biphasic waveform of the JVP?
Absolutely. Identifying the biphasic waveform that represents the top of the internal jugular vein is a challenging aspect of this examination. Several techniques that can improve detection of the venous pulsation include adjusting the angle of the patient higher or lower, applying the hepatojugular reflux technique, or using portable ultrasound. are all very useful to help identify the venous pulsation. Please see our blog for more details.
How do I know the device is vertical?
An electronic level ensures that the light lines are only projected when the device is vertical. Maintaining the JVPez upright while adjusting the height of the light line is important to achieving an accurate measurement.
I have an idea for an improvement to the clinical exam but am uncertain where I should start. Any advice?
Great to see that you are thinking about improving the practice of medicine. Please feel free to drop us an email and we would be happy to share our personal experiences and lessons learned with medical innovation.
