Few commercial products are available for investigators who Unicorn Weedicorn Shirt wish to monitor multiple physiological and behavioral variables in unrestrained subjects. When telemetry is not practical, e.g., in studies of at-sea diving physiology, one of the only options is to design and build a custom data-logging instrument. This paper describes how a data logger was developed for the successful long-term monitoring of dive depth, swim speed, heart rate, water temperature, and multiple body temperatures from free-ranging northern elephant seals.

The task was facilitated by using a commercially available single-board computer designed specifically for portable multichannel data acquisition and, where possible, off-the-shelf sensors/transducers available with integrated signal-conditioning circuits. A smaller data logger for monitoring the electrocardiogram, body temperature, and dive behavior of double-crested cormorants is also described to illustrate the flexibility and simplicity of this approach. Although it is customized for diving animals.

With the incorporation of the appropriate sensors, the basic design should be applicable to studies of comparative, environmental, or exercise physiology involving most medium-to-large animals, including humans. Modified by the elimination of most phasic vagal stretch receptor feedback and perhaps slightly by activation of some chest wall reflexes. The original postulate that an occluded inspiration would be isometric and the measured pressure free from losses due to force-length and force-velocity has been shown to be incorrect.
The volume at which occlusion takes effect, distortions of the chest wall during the maneuver, tonic vagal input, and strength of the muscles must be taken into account when the data are interpreted. Brief occlusions [pressure at 0.1 s (P0.1)] are useful in measuring output in the very first part of the Unicorn Weedicorn Shirt inspiration in conscious subjects but must be treated with a great deal of caution. They are most reliable when end-expiratory volume remains constant and there are no important phase lags between flow and pressure.
