“…Care needs to be taken to avoid skin burning on sensitive and neonatal skin (12 There have been studies indicating that respiration rate can be extracted from plethysmograms. Plethysmograms from ten healthy adults were processed using wavelet transforms (21). Respiration waveform was observed in the plots of the wavelet transforms.…”

Respiration rate is an important indicator of a person's health, and thus it is monitored when performing clinical evaluations. There are different approaches for respiration monitoring, but generally they can be classed as contact or noncontact. For contact methods, the sensing device (or part of the instrument containing it) is attached to the subject's body. For noncontact approaches the monitoring is performed by an instrument that does not make any contact with the subject. In this article a review of respiration monitoring approaches (both contact and noncontact) is provided. Concerns related to the patient's recording comfort, recording hygiene, and the accuracy of respiration rate monitoring have resulted in the development of a number of noncontact respiration monitoring approaches. A description of thermal imaging based and vision based noncontact respiration monitoring approaches we are currently developing is provided. Pediatr.

“…The blood volume pulse that can be recorded using this setup may be used to calculate several important parameters for early noninvasive cardiovascular diagnostics. Respiratory parameters can also be deduced from the BVP at an earlier stage if the analysis of the BVP can be done using wavelet transforms (Leonard et al 2003). Monitoring of respiratory rate is currently performed by either using capnography or other methods which either requires trained personnel or expensive equipment.…”

A high sensitivity, low power, low cost sensor has been developed for sensing the blood volume pulse using transmission mode photoplethysmography (PPG) from the finger tip. It uses standard light emitting diode (LED) and phototransistor as emitter and detector, respectively. The sensor probe head is made of a material called delrin which is an acetal polymer having high dimensional stability and biocompatibility. A peripheral interface controller (PIC) microcontroller is used for the implementation of the measurement protocol. The wavelet denoising algorithm is used to suppress the noise component in the PPG signal. For heart rate (HR) estimate comparison, PPG signals are evaluated by comparing their beat-to-beat estimates with the corresponding R-R intervals from an electrocardiogram (ECG). The main advantages of the proposed approach are the reduction in cost, dimensions and power consumption. The probe can be well tolerated by the subject and is selfcontained and portable.

“…7,8,11,14,18,21,22 With the recent introduction of new techniques using estimation of time-frequency spectra for analyzing nonstationary signals, several studies have utilized short-time Fourier transform (STFT) 24,25 and continuous wavelet transform (CWT) 1,8,[16][17][18] to extract the respiratory rate from the PPG signals. However, success is predicated on obtaining the highest possible time and frequency resolution, which is impossible with either the STFT or the CWT.…”

A Novel Approach to Monitor Nonstationary Dynamics in Physiological Signals: Application to Blood Pressure, Pulse Oximeter, and Respiratory Data

We propose a parametric time-varying (TV) algorithm which utilizes sinusoids as the basis functions which are then projected onto sets of Legendre and Walsh functions for the purpose of monitoring nonstationary dynamics. The proposed algorithm is a general-purpose algorithm that has the potential to be widely applicable to various physiological signals, but is especially well-suited for tracking blood pressure (BP), pulse oximeter, and respiratory signals, as they all exhibit periodic oscillations with TV dynamics. The proposed algorithm's efficacy was verified using both simulation examples and application to experimental data from all of the above-mentioned sources. Our results show that the method can: (1) accurately monitor abrupt frequency changes even when the data are contaminated with significant noise, (2) accurately monitor the BP and pulse oximeter signals, and (3) provide accurate estimation of respiratory rates derived directly from pulse oximeter recordings.
