Do nurses help preterm babies to exhale? - page 2

Hi I am currently doing a design project. the problem given by the engineering lecturer is preterm babies have respiration difficulties. the machine that helps the babies to breathe, just help them to inhale but not exhale. there... Read More

    "I think my lecturer just want us to design the exhalation detector...."

    Actually, there is such a device that is used when a pt (adult or peds) has an endotracheal tube placed to assist breathing; it detects CO2 on exhalation and verifies that the ETtube is in the trachea, not the esophagus.

    Here's the link: Covidien EASYCAP II Co2 Detector @ Covidien EASYCAP II Co2 Detector [EASYCAP II] - $347.00 : @ Summit Surgical Technologies., Shop and save on Medical Equipment, Refrigerators, Freezers and more.

    I hope that helps!

    My first reaction is "WHAT???" I'm having visions of nurses running around the unit, massaging babies' tummies, hopefully washing their hands in between pts.

    The pathophysiology of Respiratory Distress Syndrome is that the alveoli lack surfactant which is necessary keep them open--the alveoli collapse to prenatal status; this requires the baby to re-inflate the alveoli each time s/he breathes.

    You know how hard it is to blow up a balloon the first time, then it's easier on subsequent times. When things are working properly, the 1st breath takes a lot of effort, then residual air remains in the air sacs, making it easier on subsequent breaths.

    Most respiratory assistance is aimed @ firstly providing surfactant, and then maintaining air pressure in the lungs so that the baby doesn't have to work so hard to breathe. It's called Continuous Positive Airway Pressure (CPAP). (other terms exist). This makes it easier to inhale, but they [babies] don't need any help to exhale. Sometimes CPAP is combined w/an assisted respiration from the ventilator, a change in the pressures that imitate a more natural respiratory cycle.

    Sometimes, babies swallow more air w/this therapy due to the extra air/O2 in their airways; that can be controlled in a number of ways.

    Hopefully, that helps and is in keeping w/current practice. Any one else want to chime in?
    Great reply pr!

    There is at least one mode of ventilation -high frequency oscillatory ventilation - that utilizes both active inspiration and expiration. (Active exhalation is necessary in that mode because we're trying to deliver hundreds of tiny pressure oscillations to the baby each minute.)
    This is what I was going to say.

    Look up JET ventilation, it provides inspirations through the interior et and allows the expirations to ease up the exterior naturally. Great for MAS and microprems
