Best New Disposable CPAP Devices

CPAP, or Continuous Positive Airway Pressure, is a popular therapy for CHF and other common respiratory emergencies. It helps patients inspire while delivering PEEP, or Positive End Expiratory Pressure. This combined with supplemental oxygen help patients breathe easier and often prevents progressive worsening of the respiratory emergency.

Today we have three basic types of CPAP delivery systems:

  1. Combination ventilator with CPAP
  2. CPAP standalone device
  3. Disposable CPAP systems

Disposable CPAP devices have become popular for several important reasons. They are compact and lightweight. In rural areas, where CPAP treatments may be infrequent, they are affordable because they eliminate the need for any capital equipment. They also make a great choice for first responders. Finally, they allow for faster ER turnaround time. You can simply transfer the patient with a disposable CPAP to a wall oxygen flowmeter and clear the ER quickly.

We have recently seen the introduction of quite a few new disposable CPAP systems, giving EMS providers many disposable CPAP devices to choose from. Continue

    Hello Mr. White,
    My EMS service uses the Rescuer CPAP system.
    The Rescuer CPAP system utilizes a maximum of 10Lpm of O2.
    10Lpm is roughly 167mL/s
    To receive positive pressure from a flow of 167mL/s a Pt. must inhale at a rate below 167mL/s.
    Given a tidal volume of 500mL, any person using the Rescuer CPAP system must take no less than three full seconds to inhale or they will trigger the Rescuer’s anti-suffocation valve:
    inhalation time in seconds = (tidal volume) * (flow rate)
    2.99 seconds = (500mL) * (seconds/167mL)
    Given an inhalation time that is equal to exhalation time, a person who takes 3 seconds to inhale will be breathing 10 times a minute, provided that there is no period of apnea.
    Given an anatomic dead space of 150mL, an person with this (average) anatomic dead space who is using the Rescuer CPAP system at its maximum setting of 167mL/s will require 0.9 seconds just to receive enough O2 to fill their anatomic dead space.
    When I have problems with asthma, I take less than a second to inhale and thus would not receive positive pressure from the Rescuer CPAP system.

    I hope you can convey this to someone who cares, because I have had difficulty doing so.

    Sincerely,
    Jim Miller
