Pulse and Plethysmography

Pulse Oximetry and Plethysmography are non-invasive circulatory assessment methods used in blood flow monitoring, and both methods are supported by PowerLab and LabChart.

Pulse oximetry is used to measure the oxygen level (oxygen saturation) of the blood. It is an easy, painless measure of how well oxygen is being sent to parts of the body furthest from the heart, like the arms and legs.

In conjunction with our solutions shown below, any device with an analog output (+/- 10V) can be connected to a PowerLab data acquisition system for synchronization of the event in LabChart, giving you even more flexibility and the ability to integrate your data streams in one place.

All our hardware recommended for human use is backed by the appropriate safety certification standards. More information on safety standards.

Typical Pulse and Plethysmography Studies

Heart rate and rhythm monitoring

Blood flow monitoring in peripheral vascular disorders

Cerebral perfusion monitoring in models of stroke and brain injury

Tumor perfusion monitoring

Angiogenesis

Blood flow (free flaps, pedicle flaps, wound healing, gastroenterology)

Sympathetic and parasympathetic nervous system research

Sleep studies (Polysomnography)

Signals Supported

ECG

Use ECG recording for HRV analysis and to measure the interplay between the sympathetic and parasympathetic nervous systems.

Fluid Flow

Record absolute or relative blood flow in human subjects.

Heart Rate

Options for both wireless and wired recording of heart rate as a reference to changes in cognitive and emotional states.

Pressure

Measure blood pressure to investigate the interplay between sympathetic and parasympathetic nervous systems.

Pulse

Use arterial pulse recordings to investigate the interplay between sympathetic and parasympathetic nervous systems.

SpO2

Use pulse oximetry to measure peripheral capillary oxygen saturation (SpO2) , an estimate of the amount of oxygen in the blood.

Flexible Data Acquisition

ADInstruments systems provide an integrated solution to advance life science research. With the combination of LabChart or LabChart Lightning analysis software and a PowerLab data acquisition unit, you have the flexibility to collect and synchronize a wide range of signals for analysis. We also offer a range of LabChart compatible solutions able to stream directly in LabChart.
