Focuses on the use of a portable peak flow meter with an asthma diary to help make patients more aware of imminent respiratory problems. Factors and early signs and symptoms of asthma attacks; Documentation of assessment data with an asthma diary; Treatment of asthma attacks....
By means of Wright''s Peak Flow Meter, the expiratory peak flow rate (PFR) was measured in 1011 school children aged 7 to 17 years. Of these, 779 had no objective signs or histories of disease in the respiratory organs. This group was considered as a normal material. The normal ...
Home-monitoring of peak expiratory flow rate using the mini-Wright peak flow meter is a useful technique for determining whether or not unexplained respiratory symptoms are caused by asthma. It is of particular value when airflow obstruction cannot be demonstrated at the time of consultation.关键词...
Methods We used SMS to collect symptoms and peak flow (PEF) meter readings from children with asthma. Digital PEF meters enabled data download to confirm validity of PEF data sent by SMS. Parents responded to 5 SMS messages daily for 7 days during baseline and for 14 days during a cold. ...
Counting and discrimination of polystyrene bead populations on-chip and on a benchmark flow cytometer. Histograms of the peak-to-baseline (P2B) amplitude of (a) FSC and (b) SSC signals of 3 µm, 6 µm, and 10 µm beads detected on-chip (AOCFSC of 0° and AOCSSC of 50°),...
The second significant engineering parameter is the geometry (i.e., size and fill fraction) of the Au NPs, which fundamentally determines the peak wavelength of the LSPR36,37,38. To create Au NPs on the PANI layer, we adopted a physical vacuum growth method combined with substrate cooling....
The water pumped out from outlet at the top of the flow cell and is recirculated through in a closed loop. The inlet flow rate of water into the flow cell is measured using an inline ultrasonic flow meter and the flow rate is controlled by adjusting the head of the water feed tank. ...
peak pressure increases with an increase in coating thickness. On the contrary, peak pressure was also seen to be increased for the higher compression ratios. As compared to biofuel, the complete combustion process takes place in case of diesel due to good swirling and hence relatively higher ...
13, the size of the resulting peak particle velocity is determined mainly by the geometry of the drill hole. Since the superimposition angle of the wave is affected by the design orientation sequence of the hole blasts performed on-site, there is an extensive range in the resulting PPV, ...
The peak signal-to-noise ratios (PSNR)36 measured in the transformed signal region, SU, of the light potentials in Fig. 5a–d are 45.7dB, 40.7dB, 43.8dB, and 39.9dB, respectively. Discussion Compared to previous studies (Table 1), we can generate experimental light potentials of low RMS...
