Apparatus dead space is the dead space in an artifical breathing circuit. For an intubated patient the apparatus dead space is represented by the volume of the endotracheal tube tube connectors HME and the Y-piece of the ventilator circuit; For a patient ventilated non-invasively the apparatus dead space is the volume of the NIV mask which

Sep 03 2015· The system functions at maximum efficiency when the fresh gas flow equals the minute ventilation and the dead space gas (which has not taken part in gas exchange) is allowed to be rebreathed and utilized for minute ventilation. Mapleson A is the circuit of choice for spontaneous respiration because there is negligible rebreathing.

Capnometry is the measurement of. CO2 in the respiratory gases. a Capnometer measures. CO2 levels. capnography is the. graphic display of the CO2 levels as they change during breathing. Capnometry is most use in patients that are. undergoing general anesthesia or mechanical ventilation. the capnograph must be a rapid.

Dead space is increased (by all respiratory apparatus). VD/VT = 0.33 normally 0.46 if intubated and 0.65 if mask case. Mechanical dead space ends at the point where inspired and expired gas streams diverge (the Y-connector). How is the “best” FGF determined? The fresh gas flow used determines not just FIO2 but also the speed with which

Masks are available in different sizes and different dead volumes. The aim of this study was to compare the effect of different degrees of occlusion of the mask holes and different mask dead space on the amount of nebulized albuterol available at the mouth opening in a model of a spontaneously breathing child.

T is constant and breathing frequency is reduced minute ventilation is lower. It is also likely that alveolar ventilation along with PaCO 2isconstant.This evidence suggests that there is less dead space. Lower breathing frequency with HFNC than with low-flow oxy-gen delivery has also been reported in other studies [7-10].

to almost zero [14]. Thirdly there is a poor relationship (r=0.36) between the static volume of the mask and the dynamic dead space. Even a mask with a static dead space approaching a litre had a dynamic dead space that was little different to other face masks with a much smaller static dead space. This

Minimizing dead space including using mouth pieces rather than masks may be a suitable alternative strategy in some age groups. Furthermore size adjusted Vt targets were used in all N 2 MBW measurements in adults as per current consensus guidelines ( 4 ) which may have impacted our interpretation of the Vt results.
