Background:
Noisy breathing is common at the end of life. Management of noisy breathing aims to reduce the noise via repositioning the person, suctioning the person's airways and using antimuscarinic drugs. Dying people are generally thought not to be distressed by noisy breathing at the end of life, but the noise may distress others. There is doubt on whether antimuscarinic drugs are any more effective than a placebo for noisy breathing. However, antimuscarinics are still commonly administered to people at the end of life.

Aim:
To illuminate reasons behind decision making and noisy breathing at the end of life.

Methods:
Semi-structured interviews and ‘self-recorded brief accounts’ with healthcare professionals.

Findings:
Noisy breathing at the end of life is viewed as both a natural and a medical phenomenon. However, while most participants in the interviews thought that antimuscarinics were uneffective, the prescription and administration of antimuscarinics were embedded within professional culture.

Conclusion:
Managing noisy breathing is a complex issue that incorporates natural and medical viewpoints and has a long-standing culture of practice. Research should aim to determine best practice and reduce a person's distress at the end of life.
