“…Heart rate variability is commonly used to investigate the regulation and modulation of ANS. Decreasing heart rate in phase two resembles a calming effect of AHMPS, which was the decreasing of anxiety [8,[21][22][23][24][25]30]. The Inflatable wrap models can reduce anxiety in children with ASD.…”

“…The Pulse oximeter as Photoplethysmography (PPG) device is a simple and non-invasive optical method for investigating individual's physiological parameters like oxygen saturation, heart rate, respiratory rate, and blood pressure. Infrared light from the device reads changes in blood concentration which is interpreted as a pulse rate in beat per minute (BPM) [25].…”

This preliminary study proposes to investigate (i) the mean comfortable deep pressure of Autism Hug Machine Portable Seat (AHMPS) manual pull and inflatable wrap models; and (ii) the effect of using AHMPS in reducing anxiety in children with autism spectrum disorder (ASD). The first phase was done to determine the comfort test. Fifteen healthy adolescents (13 men and 2 women; aged 19-25 years) individuals volunteered to participate in the comfort test in determining the pressure of AHMPS, both manual pull, and inflatable wrap. The second phase was completed in children with ASD, in which the comforting pressure from the first phase was then applied to five children with ASD (4 boys and 1 girl; aged 8-15 years) from the Putra Mandiri Public Special School Semarang. All children were administered both the AHMPS inflatable wrap and manual pull as a deep pressure apparatus while traveling by bus. A pulse oximeter was used to measure heart rate variability (physiological arousal). The mean comfort pressure was obtained from 15 healthy subjects, which was 0.81 psi on the chest and 0.80 psi on the thigh for the manual pull; and 0.65 psi on the chest and 0.45 psi on the thigh for the inflatable wrap. In the second phase, the AHMPS manual pull did not significantly decrease heart rate with p=0.114, but the AHMPS inflatable wrap significantly decreased heart rate with a significance value of p=0.037. We conclude, therefore, the AHMPS inflatable wrap decreases physiological arousal in children with ASD.

“…Among them, the PPG sensor is the most sensitive to motion artifacts and has the greatest influence on the accuracy of the PPG signal. There are many analog filters and DSP methods for eliminating motion artifacts from distorted PPG signals, but they can only eliminate motion artifacts to a limited extent [ 24 ]. Therefore, eliminating motion artifacts in PPG signals is a major difficulty in developing continuous BP detection equipment in the future.…”

Continuous blood pressure (BP) monitoring is of great significance for the real-time monitoring and early prevention of cardiovascular diseases. Recently, wearable BP monitoring devices have made great progress in the development of daily BP monitoring because they adapt to long-term and high-comfort wear requirements. However, the research and development of wearable continuous BP monitoring devices still face great challenges such as obvious motion noise and slow dynamic response speeds. The pulse wave transit time method which is combined with photoplethysmography (PPG) waves and electrocardiogram (ECG) waves for continuous BP monitoring has received wide attention due to its advantages in terms of excellent dynamic response characteristics and high accuracy. Here, we review the recent state-of-art wearable continuous BP monitoring devices and related technology based on the pulse wave transit time; their measuring principles, design methods, preparation processes, and properties are analyzed in detail. In addition, the potential development directions and challenges of wearable continuous BP monitoring devices based on the pulse wave transit time method are discussed.
