DO I NEED TO BUY A CPAP HUMIDIFIER WITH MY CPAP MACHINE?
WHAT IS A CPAP HUMIDIFIER?
A CPAP humidifier is used in tandem with a CPAP machine. At times when people use CPAP therapy, they complain of many side effects such as a sore throat, or nasal congestion. These side effects are not uncommon, but a CPAP humidifier can be used to avoid these. A CPAP humidifier can also reduce the “rainout” effect, which can occur when condensed water goes from the CPAP tubing into the patient's nasal passages, causing a lot of discomforts. Humidifiers are used to automatically adapt to the existing amount of humidity present so that ideal conditions can be provided to the mask.
WHAT ARE THE SIDE EFFECTS OF NOT USING A CPAP HUMIDIFIER?
Patients are often reported to abandon their CPAP therapy for sleep apnea if they go through the side effects of the therapy. A lack of moisture can provide breeding grounds for conditions like sinus infections and colds as well. Some severe side effects can also include bleeding and swelling, which is why the side effects must be reduced. All of these conditions are induces by a lack of moisture in the CPAP processed air, and a CPAP humidifier can be used to reduce them as it ensures that the air has some vapor in it.
The most common kind of CPAP humidifier is the heated pass over style one, which increases the temperature of the water, causing the rate of water vapor production to increase. The increase in the temperature gives more energy to the molecules, causing them to transform into the vapor state, and it is this category of CPAP humidifier which is believed to be more efficient than any other.
COOL PASS-OVER HUMIDIFICATION?
The cool pass-over style CPAP humidifier allows the airflow in the machine to pass from over a pool of water causing it to collect water vapor through evaporation. This is the traditional type of CPAP humidifier which was believed to be well suited for warmer climates and lower pressure settings. However, in recent years, it is not used a lot. The first reason is that a cool pass over CPAP humidifier has to be set up separately from the machine, increasing the space the machine takes up. In addition to this, at times when the water temperature in the pool drops, it can cause the air to become extremely cold, making it very irritating for the patient.
