Intended Patient Population/Medical Conditions; Contraindications; Adverse Effects - ResMed Astral Series User Manual

Introduction

Intended patient population/medical conditions

The intended patient population using the Astral devices are patients requiring mechanical ventilation.
Mechanical ventilation is indicated when a patient cannot achieve an appropriate level of ventilation to
maintain adequate gas exchange and acid-base balance. It can be delivered in the acute or chronic
environment, and may be delivered invasively or non-invasively to patients who may be non-dependent
or dependent on ventilation.
Patient populations who require acute mechanical ventilation may include:
• Acute respiratory failure
•
Exacerbation of chronic respiratory conditions
•
Coma
• Neuromuscular disease
Patient populations who require chronic mechanical ventilation may include:
•
Chronic respiratory failure
• Patients recovering from acute illnesses and acute respiratory failure who do not respond to repeated
attempts at weaning from a ventilator.
•
Patients with chronic disorders who only require mechanical ventilation for a portion of the day but
can maintain spontaneous ventilation on their own for several hours each day.
•
