Non-invasive ventilation (NIV) given to the right patient, in the right setting, in the right way and at the right time improves outcomes. However, national audits reveal poor practice in patient selection, clinical judgement, treatment initiation and availability of trained staff. NIV is indicated for persistent acute hypercapnic respiratory failure (AHRF) with acidosis after usual medical management in chronic obstructive pulmonary disease (COPD) exacerbation and even without acidosis in neuromuscular disorders or other restrictive conditions eg obesity hypoventilation or kyphoscoliosis. ⋯ Any presentation with AHRF is a poor prognostic indicator and outpatient respiratory follow-up is indicated following discharge. For selected patients with COPD who remain hypercapnic 2 weeks after an exacerbation, domiciliary NIV can reduce admissions and improve survival. For patients with neuromuscular disorders or kyphoscoliosis a presentation with AHRF almost always indicates the need for domiciliary NIV.

The use of regular infusions of immunoglobulin is well established as a treatment for patients with antibody deficiency and for patients requiring immunomodulation. Although efficacy is believed to be equivalent for the different immunoglobulin products, it is generally regarded as best practice not to switch from one product to another unless there is a clinical reason to change. Changes in commissioning guidance and issues with the supply of some immunoglobulin products to the UK resulted in a requirement for a significant number of patients to switch between immunoglobulin products in 2017-2018. ⋯ Results from 30 immunology centres reported a total of 802 immunoglobulin product switches. Twelve reactions were recorded, none of which required admission to hospital, one patient was treated with oral corticosteroids, the others required either no treatment or treatment with oral antihistamines. This review of immunoglobulin product switch reactions gives a clearer indication regarding the safety of product switching than has previously been published.

Pulmonary embolism, despite being common, often remains elusive as a diagnosis, and clinical suspicion needs to remain high when seeing a patient with cardiopulmonary symptoms. Once suspected, diagnosis is usually straightforward; however, optimal treatment can be difficult. ⋯ Direct oral anticoagulants have been a major advance in treatment this decade, but are not appropriate for all patients. Follow-up of patients with pulmonary embolism should be mandatory to determine duration of anticoagulation and to assess for serious long-term complications.
