SeQual eQuinox (Pulse cum Continuous Flow)

Last year when SeQual launched Eclipse 5, it seemed like there could never be a better continuous flow POC but recently SeQual itself introduced a remarkable model eQuinox which is smaller and lighter version of Eclipse 5 with added features like Multi Language voice interface.

Flow

2 modes:

  • Continuous flow
  • Pulse (On demand) Flow

Continuous Flow

Provides Continuous flow from 0.5 LPM to 3 LPM with increments of 0.5.

Pulse Flow

SeQual eQuinox is the only POC in market which provides such a massive oxygen bolus. Its Pulse dose mode with 192 mL bolus is almost equivalent to the continuous flow of 7-8 LPM.

Bolus for Pulse Settings:

Setting 1 - 16 mL
Setting 2 - 32 mL
Setting 3 - 48 mL
Setting 4 - 64 mL
Setting 5 - 80 mL
Setting 6 - 96 mL
Setting 7 - 128 mL
Setting 8 - 160 mL
Setting 9 - 192 mL

Sensitivity

A remarkable feature that eQuinox has retained from Eclipse 5 is the adjustable pulse trigger sensitivity.

The SeQual eQuinox provides 3 sensitivity settings ranging from 1-3 where patients making more efforts to breath can choose high sensitivity settings.

LCD Screen

LCD Screen displays the following:

  • Mode of Operation- Continuous ‘C’ or Pulse ‘P
  • The flow setting
  • Estimated time left on the battery – a very useful feature.

autoSAT Technology

One of the best features by SeQual, autoSAT technology helps maintain a consistent FiO2 by servo-controlling the device to meet the changing respiratory rates of the patient.

Usually, a person needs more Oxygen while walking than at rest; this feature enables SeQual eQuinox to give more Oxygen per minute to the patient to maintain his SpO2 levels.

Rise Time

The machine has this advanced feature of adjusting the Rise Time (varying the delivery speed of bolus of Oxygen in pulse mode) to increase patient comfort.

3 settings:

  • Fast (Default)
  • Medium
  • Slow

This feature mainly determines how quickly a patient receives shot of Oxygen in every breath.

Alarms

The machine has 2 LED indicators ; an LCD screen for visual indicationof alarms:

  • Yellow LED - Alert
  • Red LED – Alarm
Alarms in SeQual eQuinox

  2. SeQual Eclipse 5
  3. Invacare Solo2
  4. Philips Respironics SimplyGo

Top 3 comparison with SeQual eQuinox

  1. SeQual eQuinox v/s DeVilbiss iGo
  2. SeQual eQuinox v/s SeQual Eclipse 5 v/s Invacare Solo2
  3. SeQual eQuinox v/s Philips Respironics SimplyGo

Providing these features and specifications in one package seemed like a distant reality but SeQual has done it.

It would be extremely tough for other manufacturers to match the class of SeQual eQuinox as it is clearly the best continuous flow POC in the market.
