Venturi Mask Components and Setup
š The Venturi mask system includes an aerosol mask, corrugated tubing, oxygen tubing (line), and fixed orifice devices (color-coded adaptors).
āļø Setup involves attaching the corrugated tubing to the mask, connecting the fixed orifice device to the tubing, and attaching the air entrainment collar over the device before connecting the oxygen tubing.
ā ļø A critical step often missed is applying the air entrainment collar, which prevents external blockage of air inlet holes, ensuring the delivered oxygen concentration remains fixed.
Mechanism and Oxygen Delivery Percentages
šØ The mask works by diluting 100% oxygen entering the fixed orifice device with room air sucked in through side holes, achieving a precise Fraction of Inspired Oxygen ().
š Different color-coded fixed orifices deliver specific levels: Blue (24% ), Yellow (28% ), White (31% ), Green (35% ), Pink (40% ), and Orange (50% ).
š§ The required oxygen flow rate from the source varies by adaptor: Blue starts at , while Orange requires to achieve its maximum concentration.
Indications and Clinical Application
š The Venturi mask is indicated for patients developing retention (indicated by high in ABGs with normal saturation), primarily seen in COPD exacerbations.
š¬ļø Using the Venturi mask helps wash out excess carbon dioxide from the blood; if unsuccessful, escalation to BiPAP is necessary.
š« In COPD patients, maintain saturation between 88% to 92%, as administering 100% can suppress their hypoxic respiratory drive.
Key Points & Insights
ā”ļø The air entrainment collar is crucial; it safeguards the air inlet holes from being blocked by patient clothing or blankets, thereby maintaining the precise, fixed delivered.
ā”ļø COPD management requires delivering controlled oxygen concentrations via the Venturi mask (never 100% ) to prevent respiratory drive shutdown.
ā”ļø Oxygen flow from the source is not universal; adjust the starting flow (ranging from to ) based on the specific color-coded fixed orifice device being used.
