SYNCHRONOUS CARDIAC AND RESPIRATORY RATE

Non-contact, synchronous dynamic measurement of respiratory rate and heart rate based on dual sensitive regions

BACKGROUND Currently, many imaging photoplethysmography (IPPG) researches have reported non-contact measurements of physiological parameters, such as heart rate (HR), respiratory rate (RR), etc. However, it is accepted that only HR measurement has been mature for applications, and other estimations are relatively incapable for reliable applications. Thus, it is worth keeping on persistent studi...

Respiratory and Cardiac Emergencies

Failure of respiration and failure of the circulation are the only situations which can be said to be true neonatal emergencies in the sense that action must be taken in a matter of seconds if life is to be saved. Both may occur in birth asphyxia, a subject already discussed by Professor J. Davies (16 October, p. 164). Nonetheless, in the newborn baby several situations arise in which rapid and...

The respiratory rate.

Sir, The recording of a patients respiratory rate is an integral part of trauma scoring. Yet 10% of MTOS patients are excluded from TRISS analysis, most because one or more of the revized trauma score variables has not been assessed or recorded (Cope et al., 1989). We should like to draw attention to a respiratory rate monitor (available from Simonsen and Weel Ltd). The unit detects respiration...

Sound intensity and respiratory responses in the neonate. Comparison with cardiac rate responses.

This report is concerned primarily with the effect of sound intensity on the respiratory response in newborn infants. Each of 9 infants between the ages of 2 and 5 days was presented repeatedly with a 5-sec. duration white noise stimulus varying in intensity from 55 to 100 db., while cardiac and respiratory activities were continuously recorded. In general, the response to a sound stimulus cons...
