ResMed VPAP ST with H4i Humidifier

For Reference Only
Product Details

Therapeutic VPAP Machine for Patients with Severe Sleep Apnea

The ResMed VPAP ST with the H4i humidifier is intended for users who need a VPAP machine with a high pressure setting. With an operating pressure that can be set as high as 25 cm H20, the S8 ST is perfect for users with chronic and debilitating sleep apnea. The device comes with leak detection software and will monitor every breath to ensure that you're getting the therapy you need.

Monitors Every Breath

ResMed's EasyBreathe technology monitors every single one of your breath's while you're using your VPAP. EasyBreathe uses new software to help synchronize your respiratory cycle with the machine's pressure for a more natural breathing experience.

Quiet VPAP

The VPAP ST is one of the quietest sleep apnea therapy machines on the market. It uses a dual-fan motor that runs at a lower RPM than other machines; by using two fans, neither fan has to work too hard, which keeps the device quiet. A full 75% quieter than competing machines, the ST is silent, which will help you and your partner fall asleep faster and ensure that you're getting the best therapy possible.

H4i Humidifier

The HumidAire H4i Heated Humidifier delivers 30% more humidification than the previous H3i model. The H4i is compatible with all S8 ResMed machines, including the VPAP ST. The chamber is also bigger than the H3i, and now can hold 390 ml of water. The H4i will help relieve certain symptoms commonly associated with CPAP therapy, including dryness of the nose and throat, nasal congestion, and rainout. Get a better night of sleep and therapy with the H4i Heated Humidifier.

Automatic Leak Adjustments

ResMed's Vsync leak management system automatically adjusts the machine's pressure when the algorithm detects a leak. Even if your mask slips off, the increase in pressure will compromise for the leak event, ensuring that you get the therapy you need all night long.

Reviewers Tip:

VPAP machines are for users with severe sleep apnea only: VPAP's have higher pressure settings, and are not intended for everybody.
