BiPAP (biphasic positive airway pressure) is a form of ventilation that combines a ventilator with spontaneous breathing. The patient can breathe spontaneously through BiPAP ventilation without interrupting the preset ventilation rate.
How Does BiPAP Machine Work
Developed in the 1980s, non-invasive ventilation help machines differ from traditional ventilation machines in that they did not need tubes to enter the body to provide forced air into the airways of one person. They were first manufactured to give relief to people with sleep apnea, a condition in which the airways are obstructed or narrowed during sleep, causing a person to stop breathing for periods of 10 seconds or more. This breath stop can happen five to 50 or maybe several times an hour. Ventilatory noninvasive help machines called CPAP (Continuous Positive Airway Pressure) machines,
Bi-Level Positive Airway Pressure (BiPAP) machines are non-invasive machines that provide positive pressure while a person breathes and lowers air pressure when a person lives. Thus, BiPAP has predefined forces: PEP (expiratory pressure) and IPAP (inhalation pressure). The machine can also have a synchronization function for breaths per minute (BPM). If the sleeper does not take a breath, the pressure increases BiPAP machines, forcing the sleeping person to take a deep breath. The air pressure then decreases, allowing the person to work less against the air pressure to exhale. Because of the sleeper’s breathing varies, so does the pressure of the BiPAP, which allows the pressure to drop to change according to the needs of the person who sleeps. This ability to vary the air pressure allows the sleeper to exert less energy to exhale and sleep more deeply.
The BiPAP machine is similar to a CPAP machine, so the engine runs silently and is small enough to fit on a bedside table or small table. BiPAP machines can come equipped with a heated humidifier or unheated. The masks offered are nasal pillow masks or full face masks. Nasal pillow masks are lightweight and offer reduced pressure points and limited facial contact. They are available with or without chin support. Some are very easy to use and can be applied with one hand. Full masks cover both the nasal cavity and the mouth. Some include foam inserts for added comfort and pressure point elimination. As a rule, a sleep study – which helps determine the cause of the sleep apnea – and the doctor’s prescription are needed to receive a BiPAP machine. When you are equipped with your machine, the technician will help you determine which facial mask is best for you. Tube options vary from 1 1/2 feet to 10 feet in length and smooth inside to reduce noise and air resistance.
Connect the oxygen tube from an exhalation port of the mask to the flow meter that is also in the mask.
Connect the cable to a power outlet.
Turn on the machine with the ignition switch.
Press the “test exhalation port” button. Follow the instructions that appear on the screen and then wait for the “Complete Test” message to appear on the screen.
Press the “Monitoring” key to start the operation.
Adjust the BiPAP settings according to the doctor’s orders. Press the “Parameters” button and use the control button to select a different location. To confirm the new configuration, press the “Monitoring” button.
Change the mode with the “Mode” key. Confirm the new way with the option “Activate the new mode.”
Change the alarm settings with the “Alarm” button. Use the control button to adjust the settings and then confirm the settings with the “Monitoring” button.
Place the mask over the patient’s face. The machine has a strap that wraps around the head on the forehead, so it connects one to each side of the mouth. The mask should be adjusted without air leaks.
Stay with the patient for 15 to 30 minutes to make sure it fits the machine. If the patient seems uncomfortable or is having adjustment problems, contact the doctor. He may decide to change the BiPAP configuration.
