Pressurized metered-dose inhalers (pMDIs) and nebulizers are routinely employed for aerosol delivery in mechanically ventilated patients. A significant proportion of the aerosol deposits in the ventilator circuit and artificial airway, thereby reducing the inhaled drug mass. Factors influencing aerosol delivery during mechanical ventilation differ from those in spontaneously breathing patients. The English language literature on aerosol delivery during mechanical ventilation was reviewed… 
Dry powder inhaler in mechanical ventilation and influence of ventilator circuit-related factors on aerosol delivery during mechanical ventilation
TLDR
This review will summarize the state of the art for aerosol delivery to mechanically ventilated patients with special emphasis on emerging opportunities for dry powder aerosols.

TLDR
Aerosol therapy is indicated in patients supported by invasive mechanical ventilation for management of asthma, bronchospasm, increased airway resistance, intrinsic positive end-expiratory pressure, difficult to wean, and ventilator dependent patients where compatible aerosol device is not available.

TLDR
The techniques of administration of aerosols with various delivery devices during mechanical ventilation are well known, but there continues to be significant variation in clinical practice and guidelines are needed to provide best practices for a wide range of clinical settings encountered in mechanically ventilated patients.
Improving Aerosol Drug Delivery During Invasive Mechanical Ventilation With Redesigned Components
TLDR
Streamlined components can significantly improve the delivery of pharmaceutical aerosols during mechanical ventilation based on an analysis of multiple aerosol generation devices, ETT sizes, and flows.
Inhalation therapy in patients receiving mechanical ventilation: an update.
TLDR
The impact of various factors on aerosol delivery with pMDIs and nebulizers is reviewed, and the correlation between in-vitro estimates and in- vivo measurement of aerosol deposition in the lung is elucidated.
Optimized aerosol delivery to a mechanically ventilated rodent.
TLDR
The addition of a recycling step may prove to be a significant improvement in achieving higher deposition in mechanically ventilated lungs; however, the suitability of the test agent for repeated nebulization needs assessment is still unclear.
Effect of Nebulizer Designs on Aerosol Delivery During Non-Invasive Mechanical Ventilation: A Modeling Study of In Vitro Data
TLDR
Nebulizer design has a great role in efficacy of jet nebulizer but not VMN and different types of JN should not considered interchanges without dose adjustment, and modeling can optimize these results for better aerosol delivery.
Evaluation of Aerosol Drug Delivery Options during Adult Mechanical Ventilation in the COVID-19 Era
TLDR
Drug delivery using a VMN was significantly greater than that with a JN and pMDI for both standard and LTV ventilation, and the highest dose observed using the CombiHaler was observed.

Aerosol delivery from a metered-dose inhaler during mechanical ventilation. An in vitro model.
TLDR
It is concluded that in addition to other known factors such as dose, type of spacer, and its position the technique of administering MDIs in mechanically ventilated patients markedly influences lower respiratory tract aerosol delivery.
Aerosol delivery and modern mechanical ventilation: in vitro/in vivo evaluation.
TLDR
Aerosol delivery in ventilated patients can be efficient and reproducible only if defined ventilator parameters are tightly controlled, and key parameters can be determined via in vitro bench testing defining delivery standards for clinical trials of drugs with narrow therapeutic/toxicity ratios.

TLDR
Pressurized metered-dose inhalers of bronchodilator and corticosteroid aerosols are more efficient and convenient to use than nebulizers for routine therapy in ventilated patients and further work is needed to enhance drug delivery in this setting.

TLDR
At appropriate flow rates and concentrations, He-O2 in the ventilator circuit may improve aerosol delivery in mechanically ventilated patients with severe airway obstruction.
Nebulizer function during mechanical ventilation.
In the setting of mechanical ventilation, recent studies have cast doubt on the ability of nebulizer systems to deliver adequate amounts of medication. We therefore studied ventilator-related and

TLDR
To minimize aerosol loss within artificial airways, an endotracheal tube of the appropriate size should be selected and "Priming" the tube with a few doses of aerosol before use decreases the electrostatic charge on its walls and may reduce aerosol deposition within the tube.

TLDR
With a better understanding of the many factors influencing aerosol delivery and deposition in mechanically ventilated patients, it is possible to provide a scientific basis for inhaled bronchodilator therapy in these patients.
