Observations on the distribution of alcohol in blood, breath, and urine.
It is important to know whether a direct determination of blood will be needed for law-enforcement purposes or whether the blood-alcohol level can be deduced from the amount present in breath or urine. Expand
The effect of haematocrit on the resistivity of human blood at 37°C and 100 kHz
In order to be able to employ the electrical-impedance method for the measurement of cardiac output in patients on haemodialysis where a wide range of haematocrits may be encountered, a knowledge of… Expand
The changes in blood resistivity with haematocrit and temperature
The temperature dependence of the resistivity of blood samples with haematocrits from 16 to 52.5% has been investigated over the temperature range of 22° to 40 °C at a frequency of 100 kHz. The… Expand
The use of the electrical-impedance technique for the monitoring of cardiac output and limb bloodflow during anaesthesia
The calculation method used for the stroke volume is to some extent empirical; nonetheless the values obtained compare well with those obtained by the dye-dilution technique in patients with normal hearts and lungs. Expand
A comparative study of the performance of five commercial blood-gas and pH electrode analysers.
A comparison has been made of the performance of five commercially available bloodgas and pH analysers and each analyser is rated in terms of its characteristics and ease of use. Expand
Electromyography of the detrusor muscle.
Studying 70 female patients with micturitional disturbances by monitoring pulse, respiration, intrinsic bladder pressure, urine flow rate and volume, and detrusor and sphincter electromyograms during a 2 to 4-hour period found that the high frequency activity is similar to that of striated muscle.

Inflammable antiseptics and theatre fires
This paper describes an investigation designed to find out if theatre fires could be started by the antiseptic painted on the patient's skin being ignited by cautery or diathermy.
Significance of variations in blood: breath partition coefficient of alcohol.
It is obvious that substantial variations occurred from one person to another in the derived values and that even in the same person the use of the partition coefficient of 2100 led to significant differences between the direct and derived values for blood, and these differences changed with time.
