Ventilator breath delivery

In this educational series, we discuss the different modes of ventilation, triggering and cycling, ventilator patterns, as well as features and software options unique to the Puritan Bennett™ 980 ventilator.

Byte 1: Modes of mechanical ventilation

Learn the types of breaths that can be delivered to the patient, what the ventilator allows the patient to do by themselves, and adjuncts to breath delivery provided by the ventilator.

Byte 2: Basic components of ventilator breathing

Learn about the four primary components of the ventilator breath cycle: the trigger phase, the inspiratory phase, the cycling phase, and the expiratory phase.

Byte 3: Trigger methods in mechanical ventilation

The mandatory ventilator breath can be patient-triggered, using a flow, pressure, or neural signal from the patient, or time-triggered, based on the breathing frequency set on the ventilator by the operator. Learn about the ways a ventilator phase can be initiated.

Byte 4: Ventilation control parameters

In this video we learn about control parameters, which are based on pressure, flow, or time, and the part they play in breath inflation.

Byte 5: Cycling of the mechanical ventilator breath

The term cycle is used to describe the transition from the inspiratory to the expiratory phase of a positive pressure inflation. Learn more about three types of cycling: volume, flow, and time.

Byte 6: Inflation breath types

The lung inflations provided by mechanical ventilation can be separated into two general types of breaths: spontaneous breaths and assured breaths.

Byte 7: Definitions for breath strategies

Learn more about some very common spontaneous and assured inflation types: volume control, pressure control, volume-targeted pressure control, pressure support, and volume-targeted pressure support.

Byte 8: Ventilator modes/patterns and how they work

Ventilators offer a number of modes, which may also be called patterns. Learn about the different ways in which they interact with patients.

Byte 9: Adjuncts to mechanical ventilation

Learn about the selectable ventilator functions (tube compensation, assured constant airway pressure, leak compensation) superimposed on suitable breath delivery schemes that can modify breath delivery for a patient’s treatment.

Byte 10: PAV+™ software

It can be challenging to protect your ventilated patient’s comfort, diaphragm, and lungs. Learn how to help your patient direct their breathing while helping you manage patient work of breathing.

Byte 11: Leak Sync software

Learn how to reduce leak-related auto-triggering and delayed cycling asynchronies during invasive and noninvasive ventilation in neonates to adults.

Byte 12: NIV+ software

Neonatal NIV is typically delivered through nasal prongs or a face mask that connects to or is used in place of the breathing circuit wye connector. The resistance of the NIV interface and the leaks common during neonatal NIV cause a difference between the pressures displayed on a ventilator and the pressures delivered through the nose/mouth of the baby. We discuss how to help reduce the uncertainty around effective pressure delivery during NIV for neonates as well as provide more robust disconnect detection of the prongs or mask.

Byte 13: Pressure control

Find out how pressure control can allow for more natural breathing compared to volume control while delivering consistent mean airway pressure (MAP) to the patient.

Byte 14: BiLevel software

This episode introduces BiLevel ventilation, how it works, and its clinical benefits, such as spontaneous breathing during all phases of breathing and the potential to improve oxygenation and reduce sedation in your patients.*

Byte 15: Noninvasive ventilation (NIV)

Learn about the benefits of noninvasive ventilation as well as how to address triggering, synchrony, and monitoring challenges associated with leaks.

Byte 16: Tube compensation

Find out how tube compensation differs from pressure support in the way it helps your spontaneously breathing patients overcome the flow resistance of the artificial airway and potentially reduce their amount of work needed to breathe.

Byte 17: Volume support

Discover the differences between pressure support and volume support settings on your Puritan Bennett™ 980 ventilator.

Byte 18: Volume control plus

In this final episode, learn how delivered pressure is regulated to the lowest pressure that will deliver the user-set tidal volume despite changing lung conditions.

Please pay close attention to warnings and their associated consequences as described in the Puritan Bennett™ 980 ventilator operator’s manual. The ventilator system is not intended to be a comprehensive monitoring device and does not activate alarms for all types of conditions. Do not operate the ventilator in a magnetic resonance imaging (MRI) environment. Risks associated with using a mechanical ventilator include but are not limited to hypoxemia, hypercarbia, hypocarbia, and infection.
