Come closer! MR-Conditional up to 50 mT

The HAMILTON-MR1 allows you to get close to the MRI scanner, because it is designed to withstand a static magnetic field of up to 50 mT. In comparison to ventilators with weaker shielding from the magnetic field, it gives you more freedom when positioning the device, a wider range of movement, and greater flexibility for your workflow and patient setup.

Closer proximity to the scanner also means you can use shorter breathing circuits. The advantage is their smaller compressible volume, which can contribute to better overall ventilation quality.

HAMILTON-MR1 pushing quick release button

Click on, click off. For an easy transition

The quick‑release button on the transport kit allows you to detach the device from the trolley with just the push of a button. And it reattaches just as easily.

With the new Software update 3.0 for the HAMILTON-MR1, the audiovisual TeslaSpy alarms on the are now mirrored on both the ventilator display and the alarm lamp for greater visibility. TeslaSpy is a magnetic field navigator which continuously measures the background magnetic levels, even when the ventilator is switched off. It lets you know when magnetic field levels are safe, and when they exceed the ventilator’s safety threshold. The TeslaSpy alarms are now also included in the Event log. The Software Update 3.0 brings a lot of new features to our compact devices. To learn more go to: www.hamilton-medical.com/compact-device-more-features The availability of SW v3.0.x, as well as individual features, depends on the specific device and market.

Your lookout is on board. To navigate the magnetic field

The onboard magnetic field navigator, TeslaSpy, continuously monitors the magnetic field and gives you an audible and visual signal if you are getting too close. Positioning a medical device too close to the MRI scanner can have fatal consequences.

The TeslaSpy alarms are mirrored on the device's GUI and on the alarm lamp. For maximum safety, TeslaSpy continues monitoring even when the ventilator is switched off.

Customer voices

Until now, we ventilated our ICU patients during MRI scanning with an anesthesia ventilator. Therefore, we had to consult an anesthetist every time to handle the equipment. With the HAMILTON-MR1, we are now completely independent.

Customer voices

You can take the patient on the HAMILTON‑MR1 from the ICU down to the magnetic resonance imaging suite for an MR study and not have to change a thing about the mechanical ventilation. And that is a true advantage because you are not risking lung de‑recruitment and a patient setback, which would keep the patient in the hospital longer and make it more uncomfortable for them.

Automation; Hand turns knob button clockwise

Less knob-turning. More adaptations to your patient

To manage ventilation you usually have to set multiple parameters, such as pressure, volume, inspiratory and expiratory triggers, cuff pressure, and more. And each time your patient's condition changes, you have to make one or even several readjustments.

To simplify this process and reduce the knob-turning, we have created a range of solutions:

Adaptive Support Ventilation (ASV) is a ventilation mode that provides continuous adaptation of respiratory rate, tidal volume, and inspiratory time, depending on the patient’s lung mechanics and effort. ASV has been shown to shorten the duration of mechanical ventilation in various patient populations with fewer manual settings (​Kirakli C, Naz I, Ediboglu O, Tatar D, Budak A, Tellioglu E. A randomized controlled trial comparing the ventilation duration between adaptive support ventilation and pressure assist/control ventilation in medical patients in the ICU.

Conventional solutions for cuff pressure management require you to monitor and adjust cuff pressure by hand.

IntelliCuff secures your patient’s airway (Chenelle CT, Oto J, Sulemanji D, Fisher DF, Kacmarek RM.

A randomized controlled trial comparing the ventilation duration between adaptive support ventilation and pressure assist/control ventilation in medical patients in the ICU.

Kirakli C, Naz I, Ediboglu O, Tatar D, Budak A, Tellioglu E. A randomized controlled trial comparing the ventilation duration between adaptive support ventilation and pressure assist/control ventilation in medical patients in the ICU. Chest. 2015;147(6):1503-1509. doi:10.1378/chest.14-2599



BACKGROUND

Adaptive support ventilation (ASV) is a closed loop mode of mechanical ventilation (MV) that provides a target minute ventilation by automatically adapting inspiratory pressure and respiratory rate with the minimum work of breathing on the part of the patient. The aim of this study was to determine the effect of ASV on total MV duration when compared with pressure assist/control ventilation.

METHODS

Adult medical patients intubated and mechanically ventilated for > 24 h in a medical ICU were randomized to either ASV or pressure assist/control ventilation. Sedation and medical treatment were standardized for each group. Primary outcome was the total MV duration. Secondary outcomes were the weaning duration, number of manual settings of the ventilator, and weaning success rates.

RESULTS

Two hundred twenty-nine patients were included. Median MV duration until weaning, weaning duration, and total MV duration were significantly shorter in the ASV group (67 [43-94] h vs 92 [61-165] h, P = .003; 2 [2-2] h vs 2 [2-80] h, P = .001; and 4 [2-6] days vs 4 [3-9] days, P = .016, respectively). Patients in the ASV group required fewer total number of manual settings on the ventilator to reach the desired pH and Paco2 levels (2 [1-2] vs 3 [2-5], P < .001). The number of patients extubated successfully on the first attempt was significantly higher in the ASV group (P = .001). Weaning success and mortality at day 28 were comparable between the two groups.

CONCLUSIONS

In medical patients in the ICU, ASV may shorten the duration of weaning and total MV duration with a fewer number of manual ventilator settings.

A randomized controlled trial of 2 protocols for weaning cardiac surgical patients receiving adaptive support ventilation.

Tam MK, Wong WT, Gomersall CD, et al. A randomized controlled trial of 2 protocols for weaning cardiac surgical patients receiving adaptive support ventilation. J Crit Care. 2016;33:163-168. doi:10.1016/j.jcrc.2016.01.018



PURPOSE

This study aims to compare the effectiveness of weaning with adaptive support ventilation (ASV) incorporating progressively reduced or constant target minute ventilation in the protocol in postoperative care after cardiac surgery.

MATERIAL AND METHODS

A randomized controlled unblinded study of 52 patients after elective coronary artery bypass surgery was carried out to determine whether a protocol incorporating a decremental target minute ventilation (DTMV) results in more rapid weaning of patients ventilated in ASV mode compared to a protocol incorporating a constant target minute ventilation.

RESULTS

Median duration of mechanical ventilation (145 vs 309 minutes; P = .001) and intubation (225 vs 423 minutes; P = .005) were significantly shorter in the DTMV group. There was no difference in adverse effects (42% vs 46%) or mortality (0% vs 0%) between the 2 groups.

CONCLUSIONS

Use of a DTMV protocol for postoperative ventilation of cardiac surgical patients in ASV mode results in a shorter duration of ventilation and intubation without evidence of increased risk of adverse effects.

A randomized controlled trial of adaptive support ventilation mode to wean patients after fast-track cardiac valvular surgery.

Zhu F, Gomersall CD, Ng SK, Underwood MJ, Lee A. A randomized controlled trial of adaptive support ventilation mode to wean patients after fast-track cardiac valvular surgery. Anesthesiology. 2015;122(4):832-840. doi:10.1097/ALN.0000000000000589



BACKGROUND

Adaptive support ventilation can speed weaning after coronary artery surgery compared with protocolized weaning using other modes. There are no data to support this mode of weaning after cardiac valvular surgery. Furthermore, control group weaning times have been long, suggesting that the results may reflect control group protocols that delay weaning rather than a real advantage of adaptive support ventilation.

METHODS

Randomized (computer-generated sequence and sealed opaque envelopes), parallel-arm, unblinded trial of adaptive support ventilation versus physician-directed weaning after adult fast-track cardiac valvular surgery. The primary outcome was duration of mechanical ventilation. Patients aged 18 to 80 yr without significant renal, liver, or lung disease or severe impairment of left ventricular function undergoing uncomplicated elective valve surgery were eligible. Care was standardized, except postoperative ventilation. In the adaptive support ventilation group, target minute ventilation and inspired oxygen concentration were adjusted according to blood gases. A spontaneous breathing trial was carried out when the total inspiratory pressure of 15 cm H2O or less with positive end-expiratory pressure of 5 cm H2O. In the control group, the duty physician made all ventilatory decisions.

RESULTS

Median duration of ventilation was statistically significantly shorter (P = 0.013) in the adaptive support ventilation group (205 [141 to 295] min, n = 30) than that in controls (342 [214 to 491] min, n = 31). Manual ventilator changes and alarms were less common in the adaptive support ventilation group, and arterial blood gas estimations were more common.

CONCLUSION

Adaptive support ventilation reduces ventilation time by more than 2 h in patients who have undergone fast-track cardiac valvular surgery while reducing the number of manual ventilator changes and alarms.

Evaluation of an automated endotracheal tube cuff controller during simulated mechanical ventilation.

BACKGROUND

Maintaining endotracheal tube cuff pressure within a narrow range is an important factor in patient care. The goal of this study was to evaluate the IntelliCuff against the manual technique for maintaining cuff pressure during simulated mechanical ventilation with and without movement.

METHODS

The IntelliCuff was compared to the manual technique of a manometer and syringe. Two independent studies were performed during mechanical ventilation: part 1, a 2-h trial incorporating continuous mannikin head movement; and part 2, an 8-h trial using a stationary trachea model. We set cuff pressure to 25 cm H2O, PEEP to 10 cm H2O, and peak inspiratory pressures to 20, 30, and 40 cm H2O. Clinical importance was defined as both statistically significant (P<.05) and clinically significant (pressure change [Δ]>10%).

RESULTS

In part 1, the change in cuff pressure from before to after ventilation was clinically important for the manual technique (P<.001, Δ=-39.6%) but not for the IntelliCuff (P=.02, Δ=3.5%). In part 2, the change in cuff pressure from before to after ventilation was clinically important for the manual technique (P=.004, Δ=-14.39%) but not for the IntelliCuff (P=.20, Δ=5.65%).

CONCLUSIONS

There was a clinically important drop in manually set cuff pressure during simulated mechanical ventilation in a stationary model and an even larger drop with movement, but this was significantly reduced by the IntelliCuff in both scenarios. Additionally, we observed that cuff pressure varied directly with inspiratory airway pressure for both techniques, leading to elevated average cuff pressures.

New frontiers in aerosol delivery during mechanical ventilation.

Dhand R. New frontiers in aerosol delivery during mechanical ventilation. Respir Care. 2004;49(6):666-677.

The scientific basis for inhalation therapy in mechanically-ventilated patients is now firmly established. A variety of new devices that deliver drugs to the lung with high efficiency could be employed for drug delivery during mechanical ventilation. Encapsulation of drugs within liposomes could increase the amount of drug delivered, prolong the effect of a dose, and minimize adverse effects. With improved inhalation devices and surfactant formulations, inhaled surfactant could be employed for several indications in mechanically-ventilated patients. Research is unraveling the causes of some disorders that have been poorly understood, and our improved understanding of the causal mechanisms of various respiratory disorders will provide new applications for inhaled therapies.

Advanced nebulizer designs employing vibrating mesh/aperture plate technologies for aerosol generation.

Waldrep JC, Dhand R. Advanced nebulizer designs employing vibrating mesh/aperture plate technologies for aerosol generation. Curr Drug Deliv. 2008;5(2):114-119. doi:10.2174/156720108783954815

Recent technological advances and improved nebulizer designs have overcome many limitations of jet nebulizers. Newer devices employ a vibrating mesh or aperture plate (VM/AP) for the generation of therapeutic aerosols with consistent, increased efficiency, predominant aerosol fine particle fractions, low residuals, and the ability to nebulize even microliter volumes. These enhancements are achieved through several different design features and include improvements that promote patient compliance, such as compact design, portability, shorter treatment durations, and quiet operation. Current VM/AP devices in clinical use are the Omron MicroAir, the Nektar Aeroneb, and the Pari eFlow. However, some devices are only approved for use with specific medications. Development of "smart nebulizers" such as the Respironics I-neb couple VM technologies with coordinated delivery and optimized inhalation patterns to enhance inhaled drug delivery of specialized, expensive formulations. Ongoing development of advanced aerosol technologies should improve clinical outcomes and continue to expand therapeutic options as newer inhaled drugs become available.
