PFT Machine

 A
PFT machine, or pulmonary function testing machine, is a device used to measure how well your lungs are working. It measures how much air you can breathe in and out, and how quickly you can exhale. PFT machines are used to diagnose and monitor a variety of lung conditions, including:




* Asthma
* Chronic obstructive pulmonary disease (COPD)
* Cystic fibrosis
* Bronchiectasis
* Pulmonary fibrosis
* Sleep apnea
* Interstitial lung disease
* Lung cancer

PFT machines can also be used to assess lung function before surgery and to monitor the effectiveness of lung treatments.

There are two main types of PFT machines: spirometers and plethysmographs.

**Spirometers** are the most common type of PFT machine. They measure how much air you can breathe in and out, and how quickly you can exhale. To use a spirometer, you will sit or stand in a comfortable position and place a mouthpiece into your mouth. You will then breathe in as deeply as you can and then exhale as forcefully and quickly as you can. The spirometer will measure the amount of air you breathe in and out, as well as the speed of your exhalation.

**Plethysmographs** are less common than spirometers, but they can provide more information about lung function. Plethysmographs measure the volume of air in your lungs and how easily your lungs can expand and contract. To use a plethysmograph, you will sit or stand inside an airtight box and breathe through a mouthpiece. The plethysmograph will measure the changes in air pressure inside the box as you breathe.

PFT machines are generally safe and easy to use. However, there are some potential risks, such as lightheadedness, dizziness, or chest pain. These risks are rare, and the benefits of PFT usually outweigh the risks.

What Is Ultrasound

What Is Ultrasound An  ultrasound scan , also referred to as a sonogram ,  diagnostic sonography , and ultrasonography , is a device that uses high frequency sound waves to create an image of some part of the inside of the body, such as the stomach, liver, heart, tendons, muscles, joints and blood vessels. Experts say that as sound waves, rather than radiation are used, ultrasound scans are safe. Obstetric sonography is frequently used to check the baby in the womb. Ultrasound scans are used to detect problems in the liver, heart, kidney or the abdomen. They may also be useful in helping the surgeon when carrying out some types of biopsies. The word "ultrasound", in physics, refers to all sound with a frequency humans cannot hear. In diagnostic sonography, the ultrasound is usually between 2 and 18 MHz. Higher frequencies provide better quality images, but are more readily absorbed by the skin and other tissue, so they cannot penetrate as deeply as lower fre

Electronics Ciruits : Mosquito repellent circuit

Image
Electronic mosquito repellent schematic circuit This  electronic mosquito repellent schematic circuit  diagram based on the  555 timer IC  is a simple and useful  mosquito repellent circuit  . This mosquito repeller circuit generate an ultrasonic sound with a high output frequency that  allows spreading mosquitoes within a wide radius . The circuit is quite simple and require few external components . The oscillation frequency is given by the value of the R1, R2 and C1 components and can be modified changing the value of components or replacing the R2 fixed resistor with a variable resistor ( potentiometer ) . The actual oscillation frequency of this electronic mosquito repeller circuit is around 45 KHz ( 46.5 KHz) so you need to use a good high frequency speaker , you can use a piezo speaker . The circuit can be supplied from a 9 V DC power supply  . This repeller circuit can be used for almost any animal , it works on  : cats , dogs , rats  . Even if you don’t hear the sound ge
