Why breathing matters during pregnancy
As your baby grows, your body undergoes remarkable changes — including significant shifts in how you breathe. Understanding these changes helps you take proactive steps to protect your respiratory health.
Your diaphragm shifts upward
As your uterus expands, it pushes your diaphragm up by as much as 4 cm. This reduces lung capacity and can make breathing feel more effortful, especially in the third trimester.
Oxygen demand increases
Your body needs up to 20% more oxygen during pregnancy to support your growing baby, placenta, and increased blood volume. Your respiratory system works harder than ever.
Mucus membranes swell
Hormonal changes cause nasal and airway mucus membranes to swell, making congestion and breathlessness more common — even in women with no prior respiratory history.
Breathing affects labour outcomes
Strong, controlled breathing during labour helps manage pain, maintain oxygen levels for your baby, and reduce the risk of complications. Practising breathing techniques before labour makes a real difference.
Common respiratory challenges in pregnancy
Many expectant mothers experience respiratory symptoms that are often dismissed as 'just pregnancy'. Recognising them early means you can take action.
- Shortness of breath, especially when lying down or climbing stairs
- Persistent nasal congestion and post-nasal drip
- Increased mucus production and difficulty clearing airways
- Reduced exercise tolerance due to breathlessness
- Worsening of pre-existing asthma or allergic rhinitis
- Anxiety linked to feeling unable to take a full breath
If you experience severe shortness of breath, chest pain, or rapid breathing at rest, consult your healthcare provider immediately.
How RespiPEP supports expectant mothers
RespiPEP is a Positive Expiratory Pressure (PEP) device that helps keep airways clear, strengthens breathing muscles, and supports respiratory wellness — safely and without medication.
Clears mucus naturally
The oscillating airflow created by RespiPEP loosens and mobilises mucus in the airways, making it easier to clear — reducing congestion without decongestant medication.
Strengthens breathing muscles
Regular use of RespiPEP provides gentle resistance training for your respiratory muscles, improving breathing capacity and endurance — valuable preparation for labour.
Drug-free and safe in pregnancy
RespiPEP works through airflow physics, not medication. It is a non-pharmacological device suitable for use throughout pregnancy under the guidance of your healthcare provider.
Supports post-partum recovery
After delivery, RespiPEP can help restore lung function and clear any secretions that may have accumulated, supporting a faster return to full respiratory health.
