Metabolic function during exercise is most often analyzed by interrogating the gas exchange occurring in the lungs of an exercising subject. For a typical metabolic study for exercise physiology, the following variables are recorded: Inspired or...

Blood pressure is the pressure exerted by blood on the surrounding vessel walls as it is pumped around the cardiovascular system by the heart. The ability to measure continuous arterial and vascular pressure signals directly at the source through...

Non-invasive Blood Pressure recording allows you to capture intermittent blood pressure data in awake rats or mice over long sampling periods easily and unobtrusively with a high standard of care. Reliably record and monitor blood pressure using...

ADInstruments offers streamlined solutions for stimulus presentation and the recording and analysis of evoked responses. The combination of SuperLab and StimTracker from Cedrus with PowerLab and LabChart lets you create an integrated system with...

Wireless monitoring in exercise and sports science provides freedom of movement for your subjects, ensuring you are observing realistic human activity in your research. ADInstruments’ wireless solutions are ideal for a wide range of applications and...

Non-invasive Blood Pressure (NIBP) recording in the field of exercise and sports science allows you to capture continuous blood pressure data over long sampling periods easily, and with increased comfort for your subject. Reliably record and monitor...

Using wired (tethered) physiological monitoring you can collect precise movement data, record joint movement, and measure muscle activity with absolute confidence. ADInstruments offer a wide range of wired solutions for studying the mechanics...

The ability to easily record and measure various physiological responses is a key requirement in psychophysiology where the focus is on the relationship between mental and physiological processes. Some of the most common physiological processes...

Heart Rate Variability (HRV) is determined by analyzing the time series of beat-to-beat intervals from an electrocardiogram (ECG). HRV is a popular tool within psychophysiology as it can be an easy indicator to assess the relative contributions of...

Non-invasive Blood Pressure (NIBP) recording in the field of psychophysiology allows you to capture continuous blood pressure data over long sampling periods easily, and with increased comfort for your subject. Reliably record and monitor trends in...

What is Electrocardiography (ECG/EKG)? Electrocardiography (ECG or EKG) studies the heart's electrical activity produced during myocardial contraction and relaxation, usually recorded by electrodes on the skin. ECG signals are recorded to examine...

NIBP Recording & Analysis Machines Non-invasive Blood Pressure (NIBP) recording for cardiovascular research gives you the ability to capture continuous blood pressure data over long sampling periods easily, and with increased comfort for your subject...

Spirometry is a lung function test which measures the amount (volume) and speed (flow) of air that can be inhaled or exhaled from the lungs. Spirometry is an important tool for assessing conditions such as asthma, chronic obstructive pulmonary...

Invasive blood flow meters allow you to perform accurate and precise fluid flow measurements in or around blood vessels in mice through to large animals and even atypical animal models such as fish. With different sensors, these devices can also be...

Changes in ventricular function for both normal and diseased conditions can be studied through analysis of ventricular pressure volume loops. The gold standard method for measuring direct, real-time complete cardiac function, particularly myocardial...

Under pressure to deliver results? We have everything you need for human invasive blood pressure monitoring - measure blood pressure intravenously in humans, from atria to arteriole. Use our human-approved invasive blood pressure equipment -...

FDA 21 CFR Part 11没有规定必须用于归档数据的特定类型的媒介，因为各种可用媒介没有标准寿命。 用户有责任确保在要求的时间内正确存档所有数据。

Millar 压力导管的工作范围为-760到4000毫米汞柱。这些压力传感器的线性工作范围是-50至300毫米汞柱。 对于任何超出线性范围的压力，用户必须在他们期望的工作压力范围内进行非线性校准。用户可以使用LabChart多点校准扩展来校准压力传感器。 客户将需要生成压力范围，以便执行非线性校准。该扩展可以从ADInstruments网站的 下载页面免费获得，并可与用于Mac OS和Windows的LabChart一起使用。

建议使用每公斤体重1/4 CC的15-30％高渗盐水进行大型动物盐水校准。 理想的情况是从低于此水平的体积开始并逐步提高直至最佳反应速度。

对于非啮齿类ECG, ECG分析模块通过首先找到T波峰值时间点(T-peak)来估计T波结束点。在峰值之后下降斜率上，从70%到30%绘制一条最小二乘拟合线。然后将T波结束点标记为拟合线与波形的等电电平的交点。它不是等电位线与心电信号本身的交点。 啮齿动物的T波结束点则是简单地利用心电图信号本身与等电力线的交点。 在LabChart的帮助菜单中，在本页底部的“Calculations”小节下面，“ECG average”页面中有一节描述了这些算法。
