CPAP machine is one of the effective at solutions to sleep apnea, here we provide a detail CPAP machine reviews, which may help your sleep apnea treatment.

At present, the various CPAP machine treatment is based on the same principle, which is through the nasal mask connected to ventilator and the patient, continued to have a positive pressure ventilator flow, acting on the upper airway, so that the upper airway open during sleep state, thus avoiding the occurrence of apnea and hypoxia.

According to the work mode, CPAP machine can be divided into three types:

1. Common type of manual regulator CPAP

Treatment stress need to manually set, the pressure does not change after setting in the entire treatment process, which is the simplest sleep machine.
Advantage: relatively cheap
Disadvantage: Patients need higher treatment pressure, poor comfort.

2. Intelligent automatic voltage sleep apnea machine (Auto-CPAP)

The most important feature of this machine is that it can continuous monitoring of the degree of airway obstruction in the treatment of patients, and adjust the treatment stress timely based on the degree of airway obstruction.
A: lower average pressure treatment, patients feel more comfortable and have a higher treatment compliance.
D: higher price.

3. Bi-level sleep machine (BiPAP)

The kind of machine is characterized by inspiratory and expiratory pressure can be adjusted separately, that is CPAP machine sends high default inspiratory pressure when inhaling air and help patients inhale more air， in contrary, CPAP machine switches to a preset lower expiratory pressure, help patients with easy gas exhaled. The CPAP machine pressure should seted according to the condition of patients through experienced professionals. BiPAP is suitable for cardiopulmonary failure, or patients who required higher pressure treatment .

4. Low resistance CPAP machine

This is a new ventilator mode, which is based on the common CPAP mode. The pressure with a certain degree of reduction within a short time at the start of the expiratory phase, so that patients breath easier and comfortable. This CPAP machine is particularly suitable for patients who need a higher treatment pressure or with chronic heart failure.
