Obstructive sleep apnea is a condition where physical blockages occur in a person’s airway when they are asleep. This causes breathing to stop, reduces oxygen in the blood, and leads them to wake up frequently and feel tired during the day. Positive airway pressure (PAP) therapy is the most effective and widely used method for treating sleep apnea. PAP machines keep a patient’s airway open using air pressure, preventing the airway from collapsing while asleep.
There are a variety of PAP machines available, including CPAP machines, BPAP machines, and APAP machines. To learn more about these different devices and their benefits, visit our application page.
PAP machines have a number of integrated sensors to make sure the air flow, pressure, vibration, and humidity are accurately controlled to keep the user comfortable and safe. These sensors may need to be calibrated and/or checked periodically—both during the design/manufacturing of the machine and during service.
TSI’s 5000 Series flow meters are ideal for testing and calibrating PAP therapy devices. TSI sensor technology enables flow sensing with high accuracy, fast response rate, and low pressure drop. Our 5000 Series gas mass flow meters can combine measurements of multiple instruments into one, including a digital flow meter, manometer, thermometer, and hygrometer. Using one device instead of many saves purchasing costs, calibration and maintenance costs, and asset tracking time.
