Mechanical Ventilation Clinical Considerations

For patients on a mechanical ventilator, the ultimate goal is to maintain the highest degree of ventilation, improving and promoting usage of advanced synchrony tools. This helps you set the ventilator to adapt to your patients’ unique needs and helps provide the appropriate level of support throughout the breath.

Being on a ventilator is, at times, distressing to patients — leading to signs of agitation.1 When that’s the case, you might turn to sedation.([FOOTNOTE=Siegel MD. Management of agitation in the intensive care unit. Clin Chest Med.2003;24(4):713-725.],[ANCHOR=],[LINK=]) But depending on the cause of agitation, sedation might not be necessary or recommended.

Previously, addressing ventilator-patient asynchrony was done through heavy sedation.([FOOTNOTE=Epstein SK. How often does patient-ventilator asynchrony occur and what are the consequences? Respir Care. 2011;56(1):25-38.],[ANCHOR=],[LINK=]) Recent studies have, however, highlighted the negative consequences of oversedation for ventilatory patients. This may include muscle atrophy from prolonged disuse and extended ventilation times.2

By evaluating for asynchrony, you may be able to reduce the risk of oversedation.2 And by using sedation more effectively, the potential to reduce ICU ventilation time may occur.

Driving pressure

A key to better outcomes

Driving pressure is available only in the PB980 ventilator and it is now known to be a major predictor of mortality risk in patients supported by mechanical ventilation.([FOOTNOTE=Amato MB, Meade MO, Slutsky AS, et al. Driving pressure and survival in the acute respiratory distress syndrome. N Engl J Med. 2015;372(8):747-755.],[ANCHOR=],[LINK=]) Defined as a measure of the relationship between tidal volume and effective lung size, its control can be a key to increased survival.3 The P-Drive or Driving Pressure feature of the PB980 ventilator works with the ventilator’s PAV+™ software to simplify and optimize decision-making related to this factor.

It’s part of a smart approach that helps patients breathe more naturally by adapting ventilation to their unique, individual needs. P-Drive is designed to help enhance patient support, improve outcomes and reduce the potential for ventilator-induced lung injury (VILI).

High flow oxygen therapy for enhanced patient comfort


You need easy-to-use technology to help manage oxygen delivery to patients throughout the continuum of care. 

The High Flow Oxygen Therapy (HFO2T) software option for the PB980 ventilator is designed to simplify this process by:

  • Providing a constant flow of heated and humidified oxygen and air to spontaneously breathing patients†
  • Using a single-limb circuit


High Flow Oxygen Therapy (HFO2T) software option is available only in the PB980 ventilator for neonatal, paediatric, and adult patients. Our HFO2T software can help you enhance patient care and comfort:
  • In patients with acute hypoxic respiratory failure, HFO2T has been shown to improve oxygenation and comfort, while decreasing mortality rates.([FOOTNOTE=Biselli PJ, Kirkness JP, Grote L, et al. Nasal high flow therapy reduces work of breathing compared with oxygen during sleep in COPD and smoking controls: a prospective observational study. J Appl Physiol (1985). 2017;122(1):82–88.],[ANCHOR=],[LINK=])
  • In patients with chronic obstructive pulmonary disease (COPD), HFO2T has been shown to reduce exacerbations, improve lung function, and enhance quality of life.4


The easy-to-use interface on the PB980 ventilator allows you to quickly set up the HFO2T software for a new patient. Once the patient is set up, the HFO2T screen displays only the flow and O2 parameters ― allowing you to focus on the most relevant information.


When a patient is on a mechanical ventilator, the goal is to maintain the highest degree of ventilation that can be safely delivered. Certain safety features — like backup ventilation and the alarm system — help maintain this high standard.

The PB980 ventilator series includes ventilator assurance. This means if certain elements of the system fail, the PB980 mechanical ventilator continues to deliver ventilatory support as close to the preset settings as feasible.

To put the PB840 mechanical ventilator into standby, you must turn it off, then back on. The PB980 ventilator allows you to put the ventilator on standby without having to turn the device off and on.


An alarm that increases volume over time is a priority for places like the ICU. One reason could be closed glass doors. And if clinicians are down the hall when a patient disconnects from the ventilator, they may not hear the alarm. The Puritan Bennett™ 980 ventilator elevates its decibel level at 30 seconds and again at 60 seconds automatically with an alarm that has not been responded to if the set volume is lower than the maximum setting. The Puritan Bennett™ 840 alarm has a set volume that doesn’t change automatically to alarms that have not been responded to.

Mechanical Ventilator Configurability and User Interaction

Configurability is a top priority to you, and the PB980 ventilator supports this. The PB980 mechanical ventilator touch screen works like a smartphone, offering the ability to swipe, tap, drag and drop, touch and hold, pull out, and pull down. The hot link is also designed to simplify configuration and use. The PB840 offers fewer options for selecting views, it’s not configurable, and it doesn’t provide data monitoring or graphics.

The PB980 mechanical ventilator offers:

  • Navigation. Double tap on any one of the tabs in the top row for drop downs that you can scroll through to make patient data monitoring selections. You can also drag and drop the yellow icon and drop it on areas of the screen. You will see pop-up tool tips with definitions, parameters and product/setup details.
  • Configurability. Generally, hospitals lock in certain presets, but the PB980 enables you to make changes. This flexibility is designed to better support your protocols, training, and patient-focused care delivery.
  • Patient data monitoring and graphics. There are five presets for patient data. Waveform views allow a historical look back of up to one minute of data so you can quickly check something unusual. Double tap the screen to zoom in for a maximized screen view.

An interface design can either support or complicate the workflow. The PB980 ventilator has automated tools for tasks like changing presets — which are designed to help save you time.

Mechanical Ventilation Hardware Design Differences

The PB980 mechanical ventilators offer numerous improvements on physical design. Some examples of enhancements include:

  • Battery powered compressor. This increases opportunities to transport and mobilize patients within your healthcare facility. When it is important to get patients up and walking in the ICU, for example, the ventilator can go with them.
  • Screen mobility. The PB980 ventilator’s 15-inch screen rotates 170 degrees about a vertical axis in either direction — creating 350 degrees of visibility — and can be tilted up to 45 degrees from vertical to allow for better viewing of both content and alarms. The Omnidirectional LED above the screen — on both the front and back — flashes to alert staff to alarms. The screen on the PB840 ventilator does not swivel as far, and it does not have a dome light. It provides visual alarms on the front side, which are not visible when standing behind the PB840 ventilator.
  • Secondary status display screen. If the main screen on the PB980 ventilator malfunctions, a secondary screen conveys battery status, gas status, pressure delivery, and other vital information. The PB840 ventilator does not have a secondary display, nor do many competitor ventilators.
There are many factors that distinguish the Puritan Bennett™  mechanical ventilator 980 to the Puritan Bennett™ 840 in regard to ventilator safety, configurability, user interaction, and hardware features. The Puritan Bennett™ 840 and 980 mechanical ventilation systems are designed to promote more natural breathing† — and help improve patient comfort.1



The Puritan Bennett™ 840 Plus ventilator was and continues to be one of the reliable products in Medtronic critical care ventilators’ line. It is highly responsive and offers superior comfort, delivering sensitive, precise breaths to critically sick neonatal through adult patients. With this in mind we designed and developed the Puritan Bennett™ 980 ventilator that includes some of the most innovative breath-delivery technology available and distinguish the PB980 mechanical ventilator to the PB840 related to ventilator safety, configurability, user interaction, and hardware features.
