VPAP- stands for Variable Positive Airway Pressure and it is an auto-adjusting device, an exclusive brand to ResMed. This bi-level breathing machine is quite similar to a BiPAP, delivering two different levels of air pressure to meet the demands of the widest range of patients. The VPAP helps in obtaining a more natural breathing waveform, following your inhalation and expiration phases to deliver most compliant therapy.
There are two pressure levels on a VPAP- these are the high setting and low setting. The VPAP can be recommended as a treatment option for patients with breathing related disorders and even lung disease and complications. The Hugh or Low settings can be adjusted either manually or automatically (depends on the model of the device)
ResMed has set new standards when it comes to ultra-comfortable, compliant and quiet therapy. The bi-level devices manufactured by ResMed come with plenty of innovative features which help improving therapy compliance on a long-term basis. The VPAP devices come integrated with heated humidifiers, in order to offer even more breathing comfort and battle the side effects of therapy including nasal congestion or dry mouth/throat issues.
The waveform of the VPAP delivers a smooth operation, mimicking naturally the breathing pattern of the patient. Patients feel that breathing becomes more comfortable and natural while using a VPAP. The VPAP may also have several modes such as Spontaneous, Spontaneous Timed, Timed or CPAP Mode. The device also usually features many different alarms such as Power failure alarm, mask off alarm, non-vented mask, low minute ventilation, low pressure or high pressure.
The VPAP allows for a much greater personalization than a CPAP, yet it does not adjust the pressure on an automatic basis like an APAP for example. The VPAP is typically prescribed to patients who cannot become compliant with CPAP therapy, or in case they need more customization for the therapy session. Some patients cannot stand exhaling against a high pressure coming from a CPAP. The CPAP delivers only continuous pressure, which is the actual prescribed pressure for both inhalation and exhalation.
With a VPAP, two different levels of pressure can be set. One pressure for the inhalation phase, and a much gentler, lower pressure upon exhalation. Therefore, patients who cannot become compliant with a continuous flow on both inhalation/ exhalation might be prescribed the use of a VPAP.
Just as other types of Bilevel devices, the VPAP can be prescribed for patients with more serious disorders than sleep apnea. The VPAP can be used as a treatment form for patients with COPD, Central Sleep Apnea, neuromuscular disease or even deformity of the chest wall.
VPAP devices come with an integrated humidifier. This humidifier ensures to deliver air humidity levels that are comfortable to you. The humidifier helps control the humidity and the temperature of the oxygen, keeping it at the most comfortable levels. Those patients who struggle with health conditions such as allergies, or those who have a difficulty in adapting to climate changes will find the humidifier feature extremely comfortable.
There are quite a few differences between a CPAP and a VPAP machine. The CPAP offers continuous flow, while a VPAP is capable of delivering two different pressures: one for inhalation and one for exhalation. While a CPAP machine is mostly recommended for a patient with Obstructive Sleep Apnea, a VPAP can represent a better alternative for patients with advanced respiratory illnesses, central sleep apnea or even congestive heart failure. The VPAP machines can represent the ideal treatment solution for a wider array of patients and health disorders.
Your physician is the one who will decide the exact type of machine that you require. If you consider that you cannot resist CPAP therapy because of the constant flow, talk to your doctor and he might prescribe a BiPAP or VPAP machine instead. The variable pressure levels of a VPAP will definitely offer an increased comfort and a more natural breathing pattern during the night. The lower pressure upon exhalation feels gentler, and you will not have to struggle or force your exhalation against a high pressure of air.
