Abstract

1389328 Electro-medical apparatus SIEMENS AG 14 April 1972 [17 April 1971 (2)] 17414/72 Heading G1N Respiration and heart activity of a patient are monitored utilizing an electrode 2 for providing a first respiration signal and a heart signal, and a sensor 3, e.g. a thermistor for insertion into the nose, for providing a second respiration signal, each signal being applied to a respective amplifier 4, 6, 8, frequency meter 5, 7, 9 and discriminator 10, 11, 12. Each discriminator provides zero output if the frequency of its corresponding signal is above a preset threshold and an output Uo otherwise. The three outputs U 1 , U 2 , U 3 are applied through a delay member 36 to five processing circuits 13-17 each of which is responsive to a different combination of the three signals U 1 , U 2 , U 3 . In this manner visual indications are provided at 30 and 31 should the respiration sensor 3 and the electrode 1 respectively fail, and visual and acoustic indications are provided upon cessation of respiration (alarms 32 and 33), cessation of respiration followed by cessation of the heart (alarms 32, 33 and 35), cessation of the heart (alarms 34 and 35), cessation of the heart followed by cessation of respiration (alarms 34, 35 and 33), and simultaneous cessation of respiration and the heart (alarms 33 and 35). The acoustic alarm is provided by a tone generator 42 in each case.
