In its standard (laboratory) form the Visi-3 system consists of three parts: |
|
1. A unit strapped on the patient, containing a Masimo oximeter, the connections for the transducers and the bedside unit |
|
2. Video / audio monitoring equipment (Camera, microphone and IR light) |
|
3. The recording and analysis computer. A standard PC is used: this can be in the bedroom or a nearby room. |
|
|
|
Patient connections: |
|
The only patient connections needed to record PTT, ECG, R-R interval, pulse rate, pulsatile index and oximetry are a reusable pulse oximeter sensor and three ECG electrodes. |

Our Products |

|
|
Video / Audio: |
|
A camera sensitive to infra-red monitors the patient as infra-red light source(s) illuminate the bed. A microphone calibrated in dB at the patient bed-head records snoring, and these signals are taken to the computer where they are stored digitally. |
|
|
|
Computer: |
|
The PC records and processes the signal during recording, performs the analyses, and is used to review the records. |
|
|
|
How are movements sensed without direct connection to the patient? |
|
Software monitors changes in the video signal caused by body movements. This is sensitive even to very small movements found in periodic limb movement syndrome (PLMS). |
