Abstract

A system is described for the analysis of respiratory sounds by means of a dual-channel sound envelope detector and a real-time spectrum analyzer. A three-dimensional spectral analyzer display for frequency, amplitude, and time has been utilized. Respiratory sounds have been observed with intensities up to 0.5 N/m2 and with normal frequencies in the range of 0 to 1.5 kHz. This system can extract useful information from the sounds of respiration, information which is not available by conventional auscultation.

[Anamnesis and physical examination in pneumonology].

The time the physician spends to take the patient-history is a privileged moment during which the most important informations for diagnosis are gathered which in turn will govern further investigations and measures for treatment. Among the physical examinations auscultation of the lung is often regarded as obsolete. If however acoustic phenomena are evaluated with respect to intensity, duration, pitch and position within the respiratory cycle valuable objective information can be obtained.

The susceptibility of thermistor-based esophageal temperature probes to errors caused by electrically conductive fluids ("artificial saliva").

Several brands of esophageal stethoscopes with thermistor-based thermometers were tested to determine the susceptibility of the probe connector to contamination by oral secretions. A solution of half normal saline and 1% carboxy-methyl-cellulose was used to model the conductivity and viscosity of saliva. When 1 ml of test solution was allowed to track down the probe wires to the connector, several brands of thermistors gave erroneously elevated readings. The mean changes in temperature according to brand of thermistor were as follows: Electromedics, 0.1 +/- 0.1 degree C; Mallinckrodt, 1.7 +/- 0.8 degrees C; Respiratory Products, 0.1 +/- 0.2 degrees C; Sheridan, 3.6 +/- 1.9 degrees C; Vital Signs, 4.8 +/- 1.3 degrees C (peak) and 1.4 +/- 1.6 degrees C (final); and Yellow Springs, 0.9 +/- 0.4 degrees C. The manufacturers of the probes susceptible to this type of error should implement the appropriate design modifications. In the meantime, clinicians should be aware of this problem and may choose to prevent these errors by wrapping the connection with waterproof tape.
