How to Adjust Your Fisher CPAP Machine

The Fisher CPAP machine is used to prevent airway obstruction while a patient sleeps. This is accomplished by forcing air into the breather's lungs by way of continuous positive airway pressure. While necessary to facilitate comfortable and uninterrupted sleep, forced air also has its drawbacks for CPAP users. These drawbacks include sinus irritation, chronic dry nose and nasal congestion. To counteract these effects and encourage patients to follow physician recommendations, Fisher & Paykel Healthcare has developed CPAP machines that have built-in humidifiers for a more soothing experience.

Instructions

• 1

  Increase your Fisher CPAP's ThermoSmart Humidity setting if the forced air feels too dry or too cool. You can adjust the setting with increments of 0.5 from one to four. Adjust the setting by pressing the up or down arrow buttons. The heater plate will become warmer, thereby heating the air. Decrease the ThermoSmart Humidity setting if the forced air feels too hot or is secreting too much moisture. Turning the humidity thermostat down will cool the heater plate and decrease the water level in the forced air.

• 2

  Increase your Fisher CPAP's ThermoSmart Climate setting if the forced air is too cool. This is an option for perfect temperature setting when used in conjunction with the default ThermoSmart Humidity setting. The ThermoSmart Climate setting is adjustable in increments of one from one to three. Reduce the ThermoSmart Climate setting if the forced air feels too hot or is emitting too much moisture for proper breathing. Adjust the setting by pressing the up or down arrow buttons.

• 3

  Press the ramp button on your Fisher CPAP machine in order to reduce the pressure of air being forced through. This may be necessary to facilitate sleeping. After 20 minutes, the machine will reset to full prescribed pressure. You are expected to fall asleep within 20 minutes of reducing the air pressure.

• 4

  Press the up and down buttons on your Fisher CPAP machine to increase or decrease the machine's altitude levels. The altitude setting must be accurate per location in order for an adequate air pressure to be maintained.
