Long-term Ventilation (LTV) Service

Checked: 23-10-2023 by 6 Sandi Littler Next Review: 23-10-2025

Service Overview

The long-term ventilation (LTV) service is based at the Bristol Royal Infirmary and facilitates the diagnosis of, and ongoing support for, patients with ventilatory impairment.

This is a tertiary service supporting patients in Bristol, Bath and North-East Somerset, South Gloucestershire and North Somerset.

The majority of referrals are from secondary care providers, either when ventilatory compromise leads to an acute admission or following prior diagnostic assessment in the local respiratory or neurology service.

The service cares for both non-complex patients (including obesity hypoventilation syndrome, restrictive chest wall disease, COPD, post-polio syndrome) and complex patients (including tracheostomy ventilation, neuromuscular disease and congenital hypoventilation syndrome) and has strong links to the South-West Neuromuscular Operational Delivery Network.

The team consists of physiotherapy and physiology staff and is supported by respiratory physicians, with regular input from neurology in appropriate cases.

Whilst within the service there is capacity for domiciliary patient support, this is not a community-based service and there is no capacity for urgent input, although advice can often be provided. The do work closely with local providers of Supportive and Palliative Care and community respiratory services.

Referral Guidance

Patients with suspected nocturnal hypoventilation / respiratory failure can be referred for assessment (including overnight oximetry, lung function testing and overnight sleep studies).

Referrals would usually be received from secondary care after initial diagnostic assessment, but they will liaise with primary care about both referrals and patients in our service.

This service operates during normal working hours Monday-Friday.

All outpatient referrals and queries to this service should be via letter / email to NIV@uhbristol.nhs.uk
