    This document discusses humidification, which is the process of moistening inspired air either naturally through the respiratory tract or artificially in hospitals. It describes the different methods of artificial humidification for free breathing patients with or without tracheostomy tubes and for patients on intermittent positive pressure ventilation. These include face masks, mouthpieces, T-tubes, tracheostomy masks, and humidifiers incorporated into ventilators. The ideal temperature at the entrance of the endotracheal or tracheostomy tube is 34±2°C. The document also outlines the different types of humidifiers including vapor suppliers that use heated or ambient temperature water and aerosol suppliers that use mist or ultrasonic vibration, as well as conserver humid

    Humidification

    DEFINITON
    Humidifcation is the process by which the inspired
    air is getting moistened by either the natural
    mechanisms present in the respiratory tract or by
    the artificial method used in the hospitals.
    Here the excessive heat of the air is removed and
    moisture of the air also controlled.
    When natural process of humidification fails,
    artificial humidification is used

    METHOD OF ARTIFICIAL
    HUMIDIFICATION
    A FREE BREATHING PATIENT WHO IS NOT INTUBATED
    1) A face mask
    2) A mouth piece
    These methods are used along with nebuliser as a short period of
    humidification prior to chest clearance
    A FREE BREATHING PATIENT WITH A TRACHEOSTOMY TUBE
    1) T tube ( Brompton tube)
    2) Tracheostomy mask

    A PATIENT ON INTERMITTENT POSITIVE PRESSURE


    VENTILATION (IPPV)
    Usually humidifier incorporated in to the ventilator.
    Majority of the humidifier used are heated
    The ideal temperature used at the entrance of the ET or
    Tracheostomy tube is 34 plus/minus 2o Celsius

    TYPES OF HUMIDIFIER

    SUPPLIERS: Four types


    AMBIENT TEMPERATURE VAPOUR SUPPLIERS: gas is bubbled
    through room temperature water, very fine sieve is used to obtain tiny
    bubbles.
    HEATED VAPOUR SUPPLIERS: gas is passed across through hot
    water, or dripped onto a very hot plate; patient tubing may be lagged
    or Fischer Paykell device used to prevent temperature loss and rain
    out.
    Capable of giving at over 390 C to the patient end, so caution to be
    taken not to burn the patient, safety feed back cut-off mechanism from
    a thermometer can be used.

    AMBIENT AEROSOL SUPPLIERS: uses mist of liquid


    water, by high pressure gas jet (Bernouili principle), by
    high speed spinning disc, by ultrasonic vibrating crystal.
    Over loading of mist may occur.
    A recently available method uses Babington principle,
    air forced through a fine film of water, produces dense
    mist.
    HEATED AEROSOL SUPPLIERS: water nebulised is
    heated Bernouilli type of device are used for heating or
    hot rod used. Thermal safety again needed.
    Installation: water may be directly added to the airway
    by direct instillation from a syringe, drip set or pump.

    CONSERVERS:
    These heat and moisture exchangers or
    condenser-humidifiers, trap expired heat and
    water in a mesh, and return it to fresh inspired
    gas.
    They can be reasonably efficient but are prone to
    blockage by secretions.
