Blood pressure VI

Hi guys,.

I have the VI following (partially) implemented;

If you can follow my logic... It's taking two readings of the wave of entry, when the bottom is taken the loop to complete and pass the two values in the comparison section.

My problem is that when I take high blood pressure, it reads the value, but then is reset to zero when the case structure is false.  I need a kind of buffer.  I tried to create a table of the output of the structure of matter (0 0 0 0 0 0 80 0 0 0) with the intention of then taking the maximum, although she seems to assign the variable for the 1st item in the array, and then work around it with a zero.  Someone suggested to use a local variable, even though I have no experience of them.

Any help appreciated

Peter

  • Watch Apple should have is to measure the blood pressure?

    The most important function that the Apple watch should have is to measure blood pressure.
    All people who do physical activity or do not need this important function.
    It makes no sense one shows that supports or has to help health
    without this important mechanism.

    Cardiac measurement is more important at the time of registration or
    or even stupid messages between people with Apple Watch.

    If there is to be a function of health, which will complete.

  • Is there a simple model of blood pressure for 3.2.2 numbers

    I need a model simple blood pressure for 3.2.2 numbers or earlier. Because I don't have a working knowledge of numbers 3.2.2 I hope someone can help me here. I need an auto update of date and time, systolic and diastolic pressures, and a Notes column wider. Thanks for your help since an old geezer.

    There is no integrated model, however you describe what you can do by following the following instructions:

    (1) open a new document using the menu item "file > new...» »

    (2) choose the 'Basic' category on the left, then "Blank" of the selections available:

    (2) to facilitate the entry of the date and time, I suggest the creation of a single cell table, and then enter the formula = now().  To do this, follow these steps:

    Click and hold on the A2 from the table cell (until you see the 'lift' on the table cell.

    Drag the cell above your table on the screen.

    You should see a new table like this:

    Double-click the text "Table 2", then update the text therefore reads "TimeStamp" (it's just a name is not really important).  Select cell A1 in table 'TimeStamp', then type

    = Now()

    shortcut for this is

    A1 = Now)

    Now in the original table, name the columns as the "Date", "Systolic", "Diastolic" and "Notes"... like this:

    now make the column notes wide by selecting the column for Notes (column D).  To do this click on the "D" at the top of the column.

    Now open formatter table by clicking on the 'Format' button at the top right, and then by selecting the segment 'Table':

    adjust the value for the width of the "column" down as necessary

    to enter the date in a row, click the cell in the table "TimeStamp" and select the menu item "Edition > copy" (or use the + c key combination)

    now select the cell where you want the date and time, and then select the menu item "Edition > paste formula results.

    now enter the reading notes

  • the pressure blood pressure health kit convert in numbers... help

    I have an Iphone6s and I had my annual physical and guess what...

    So I often take readings so I can get this monster under control, but I ran into a snag.

    I put my numbers on health-> dashboard-> blood pressure-> add DataPoint.

  • DAQ USB-6008 will be able to power and record voltage for UMS T5 blood pressure at the same time?

    I would use my NI USB-6008 to power my blood pressure monitor UMS T5 (http://www.ums-muc.de/en/products/tensiometer/t5.html) but also to take readings of it, but I don't know if it's possible to do it properly. The power supply for the instrument can be as low as 5V, I can easily get the dedicated + 5V channel. I'm able to feed the instrument and connect it to an analog input on the 6008 and measure a voltage in differential mode. However, when you read the documentation of support for the instrument, I find the following:

    "Potential pitfalls of data acquisition: the pressure transducer is configured in a full Wheatstone bridge, the input voltage and mV signal output can be connected to the same reference (mass)." Therefore, the mV output signal can be measured using a differential voltage measurement. Therefore, do not make an asymmetric measure of pressure transducer mV output. "(http://www.decagon.com/assets/Uploads/MeasuringUMSTensiometerswithnon-UMSControlandDataAcquisitionSystems.pdf)

    My understanding is that the 6008 can take a differential measure if I attach the signal '+' and the signal "-" to the analog inputs of positive and negative terminals. However, it seems that all the ports of ground on the 6008 are grounded to the same reference, which would make my measure of invalid tension according to the above paragraph. So my real question is: if I try to record the voltage with one of the analog inputs on the 6008 in this way, is the valid measurement? Or I need to find a separate power supply, with a different reference field to ensure that the measure is accurate?

    The technical details of this device is very poor. The manual is not much better. Companies that want to sell scientific equipment should publish decent cards or get out of business.

    In section 3.4.3 General requirements the device is described as a "bridge not amplified circuit.  This information along with the impedance of the bridge should be in the specifications, because it is essential to apply the device under any circumstances other than the nominal behavior in 10.6 V.

    The answer to your question is:

    You can use it with the box USB-6008.  The 5 V supply will result in output voltages a little less than half (5/10.6) the voltage specified in nominal conditions. You can use the differential input mode on the box USB-6008.  The absolute input voltages will be approximately 2.5 V with the 5 V power supply. This voltage is in the range of the aircraft. The differences are likely to be less than 100 mV. The resolution of the USB-6008 on the + /-1 V is located about 0.5 mV so your resolution of pressure will be about 1% of full scale. The voltage input impedance and termination of the USB-6008 will present a few errors.  These can be in the order of 5 to 10%. I can't predict much better without the missing bridge impedance specification.  These errors should be relatively constant and systematic. A calibration of the whole system - sensor and together hardware DAQ should allow you to compensate for a large part of this error.

  • Blood pressure data acquisition

    Hello
    I have some problems with the measurement of blood pressure.
    I have the sensor of pressure connected to the SensorDAQ interface. I can see SensorDAQ installed in NI MAX, but I don't really know how to get the data from the sensor to LabView using the DAQ assistant. (there is no option for the measurement of blood pressure and other measures gain data types does not work)
    Anyone have any idea or knows is it possible to get data to my pc?

    Thanks for any help.

    I am enclosing pictures with the types of measurement and automatic test SensorDAQ OR max.

    I solved this problem.

  • the basis of my time scrolls not (in my blood pressure measurements)

    I have a DC 5v pot connected to my USB DAQ 6008. In labVIEW when I run it I get my voltage output as expected but the time base does not scroll it remains fixed. When I change the axis scales the output voltage varies even in the first second only. Does anyone know what is the problem?

    I don't think you can ignore the timestamp which is part of the dynamic data. I never use dynamic data and I hope that I am never placed in a situation where I have to.

    Eventually, a difficulty for the elevator VI is in the attachment. Since you have wired some scalar indicators data, TI EÉ seems not you care about 1000 samples so I used a function average to get a scalar value at least a certain meaninig. Then I converted to a real scalar.

    If you want to paste the dynamic data, you cannot use the function bundle in VI of the gear. The correct function would be the merge of the signals feature.

  • Watch has been updated to read the voltage pressure (6/2016)?

    My doctor wants me to take my blood pressure every morning when I wake up.  Apple Watch this for me (from June 2016)?

    Since I've already paid for the watch and it reads my heart rate, the idea to buy another device to read blood pressure irks me - I've been waiting to make this available on the watch since its announcement.

    Non - Apple Watch doesn't have a blood pressure integrated monitoring capability.

  • Blood trace on Distance reading

    Hello

    I am trying to trace the readings of a cell voltage of charge (for blood pressure) on the movement of the origin of a linear actuator on the same axis.  I just want that the readings of the two while loops to enter a chart and draw the correlation between them.  Seems pretty simple, but all what I try, I can't get the table draw anything.  When I run the program in the execution of climax, it seems to stop at the end of the while loop and never feed all the data in the graph XY.  I don't know that it's just a rookie mistake that I have with the data type, or a failure to understand how the while loop needs to actually get the data to the next step.

    Please let me know what I can do.

    Is attached a photo of the VI and the VI himself.

    Thank you

    James

    You need to understand why the While loop is coming to its end.  The way you put in place, it will run until an error has occurred.

    If it stops on its own, this means that you get an error somewhere in your data acquisition sequence.  You should put an indicator on these screws to see which gives the error and why.

    Once you figure that out, he must run forevever without giving an error.  This means that it will run forever without stopping the loop, you will never get any data.  You need a better way to stop the loop.  My suggestion would be a STOP button connected to the stop of the While loop condition.

  • Registration Data (Voltage) of pressure for 1 transmitter) MS Excel 2) printing and replay) 3.

    Hello

    I have to take a blood pressure of a pressure through my USB sensor OR 6009.The DC voltage will be continuous and variable.

    I am display it on a graph like shown in the VI.

    (1) how to save the data as a text? I want to save the amplitude(Y axis) (as many points as possible, say every second) as well as the time data (X axis).

    It will be printed in my project report. I have to take readings per second, which is hard to do with a slider, manually.

    (2) how can I print the waveform on the graph? We cannot do a printscreen.

    (3) can I replay a chart later, even if the pressure sensor is disconnected?

    The chart data can be stored in some way, but the amplitude (Y axis) and time data (X axis) are unchanged from the original.

    Thank you very much.

    Well, as I said, you have to go through the tutorials and learn how things work as shift registers for loops and how to insert data into a table and back up your data at the end of the process.

    The Express VI "Write the file of measure" will probably be a quick solution to your problem because it will add a file and keep track of time for you.

  • 3D button missing in ios10

    I have an iPhone 6 more.  The 3D touch is an option with this phone?  I installed the iOS10 and the feature did not work after the installation.  I did research which must be resolved and the button isn't there yet.  From what I found, there are parameters > Accessiblitiy > Touch 3D (found just above the keyboard).  He isn't here.  I did a search in the settings on the phone itself, but nada.

    I thought to restore my phone from iTunes, but now is not an option more because when I connect I get the "iTunes could not connect because of an invalid response from the device."  After 25 years of being a satisfied customer of Apple, I'm pretty disgusted.  I would have updated the software on my MacPro fully functional (early 2009), in the hope that the two machines could talk to each other, but it seems that this is not an option because the machine is too old.  Now, I'm super disappointed.

    I have personally owned a MacPlus, a PowerMac 7100, one of the models of Bondi, a 17 "iMac, two different MacBook Pro, iPad 2, an iPhone and a tower of a MacPro."  I teach art and graphics, so I filled a laboratory at least 24 devices three times more.  I troubleshoot the machines on my own, with occasional help from my computer.  I should be able to do.

    Now I'm stuck with the problem stupid touch 3D and I am stumped.

    Sorry for all the useless fodder, but above it, nobody seems to know the wifi password at the center of fitness I'm going and I can't connect to my music either.  Other than that, life is beautiful.  My blood pressure is a little high, but yes.

    3D touch is a hardware feature that is included in the iPhone 6s and more recent.

  • Health Dashboard missing IoS10?

    I use the application health to fire the blood pressure, heart rate and blood sugar levels on a daily basis. In earlier versions of IoS, I got all this information available on a single screen--dashboard - but this seems to have disappeared from IoS10 and has been replaced by four icons oversized for activity, mindfulness, nutrition and sleep than favorites are now within each category, rather than all in one place (aka the dashboard).

    Are there plans to restore the traditional health dashboard, so his favorites are all in the same place?

    1 reset your iPhone by pressing and holding the sleep/wake and home buttons.

    2 disconnect you from your iCloud account and reconnect again.
