Question:
for this assignment, you will provide detailed responses to the following: using the aarc clinical practice guidelines, list the indications, contraindications, hazards/complications and limitations for the use of an hme during invasive mechanical ventilation. be sure to cite your source. what criteria must be met when using any heated humidification device with patients receiving mechanical ventilation? why? when is the use of heated humidifiers preferred over the use of heat and moisture exchangers (hme)? submit your answers in at least 500 words of your own on a word document. you must cite at least three references in apa format to defend and support your position.
Solution:
Use of Humidifiers in Mechanical Ventilation
Humidification of inhaled gases has been standard of care in mechanical ventilation for a long period of time. Consequently, respiratory care providers have been utilizing external humidifiers to compensate for the lack of natural humidification mechanisms when the upper airway is bypassed (Al Ashry, 2014). Based on AARC clinical practice guidelines, this paper will examine the indications, contraindications, and criteria that may be used by patients undertaking mechanical ventilation.
Indications
Humidification of inspired gas during mechanical ventilation is critical when an endotracheal or tracheostomy tube is present but optional with NIV. Recent recommendations favor the use of heated humidifiers (HH) during NIMV, reducing nasal resistance, helping expectoration and improving adhesion and comfort, especially in patients with bronchial secretions (Lellouche et al, 2014).
Contraindications
In regard to AARC guidelines, an HME
