DEVELOPMENT OF DELIVERY PROTOCOLS
It is the responsibility of the medical establishment and the medical professional to develop and establish specific delivery
protocols.
The Digital MDM Mixer is designed to deliver a variable concentration of nitrous oxide and oxygen on the continuous flow
principle. The medical professional will turn on and observe the operating indicators of the device. With the face mask/nasal
hood sealed every time the patient takes a breath, the patient will receive the full effect of the mixed gas through the face
mask/nasal hood.
Common procedures conducted with Nitrous Oxide
– Oxygen Analgesia Conscious Sedation. Ideal for minimally invasive
procedures where there is a desire for pain management to reduce anxiety or to deliver minimal sedation.
The Digital MDM Mixer is considered transient (less than 60 minutes) in terms of continuous use when providing Analgesia
(pain management), or Minimal Sedation. However, a procedure or medical condition that occurs over the course of many
hours is also considered to be using transient delivery. The upper limit of the number of hours of this described transient
delivery is at the determination of the medical professional.
Patient Population (Adult and Pediatric): Used to deliver a gas mixture to a conscious spontaneously breathing patient who
is awake, alert and cooperative and requires relief from minimal to moderate pain and is under the continuous supervision
of a healthcare professional. Age/Weight limitations: see Relative Contraindications (at the determination of medical
professional).
Note:
If using a full face mask, Porter recommends using one (DEHP-free and Latex-free) that is biocompatible for medical
use. Follow manufacturer’s instructions. The disposable mask materials have been chosen by the medical device
manufacturers of the masks intended for medical usage. Many establishment protocols also call for the use of a bacterial
filter. Follow manufa
cturer’s instructions.
Continuous Flow
The Digital MDM Mixer is a continuous flow device. Specific delivery protocols will be established for equipment.
Continuous flow devices allow the administration of variable concentrations of nitrous oxide and variable flow rates of
delivered mixture.
Some establishments have developed specific protocols for delivery with continuous flow devices, where the medical
professional is able to adjust to deliver various percentage mixes, where, with supervision, the delivery may be described
as “self-administration,” in that the patient will hold the full face mask to the face. Do not use a strap with the full face
mask. If the patient becomes drowsy the seal around the mask is lost and they will no longer inhale the Gas. It is essential
that only the patient holds the mask to prevent the onset of deeper stages of analgesia and sedation and loss of protection
of the laryngeal reflex.
