The Use of CPAP Machines in Snoring and Sleep Apnoea

Continuous positive airway pressure machines (CPAP) are medical machines that are primarily used for respiratory conditions such as sleep apnea/sleep apnoea. They are useful in other health problems such as chronic obstructive pulmonary disorder or excessive snoring. They are also used as a transition device to help people who have been intubated to get off the ventilator and back to their normal breathing.

The machine consists of a rectangular shaped box with tubes that travel in and out. These tubes are plugged into a face mask that is snugly fitted onto the face over both the nose and mouth to form a good seal. Air travels in and out of the mask under pressure helping the person breath. It is often used at night for those with sleep apnoea or snoring problems.

Sleep apnoea is a common problem that interrupts the normal breathing pattern during sleep. The airway collapses at night when the neck muscles relax thus causing an obstruction. The CPAP machine helps to maintain the airway passage such that this does not occur. The machine is usually carefully calibrated beforehand such that the pressure values would suit the person. There are many specialist sleep study centers that can help to monitor the airway pressures and detect sleeping problems.

Sleep apnoea is a serious unrecognised problems and can take a toil on a person’s social and psychological well being. It can cause excessive daytime sleepiness, and it is associated with health conditions such as high blood pressure. CPAP machines can help to alleviate these problems but there are some downsides. The machines can be quite noisy and can interrupt sleep at night. It also takes a period of time to adapt to the constant air pressure at the beginning. The other problems associated with CPAP include irritation to the eyes and throat, so regular moistening or alternatively a humidifier is required.

Recent CPAP machines are much quieter and are easier to carry around. Some models are designed to be portable and can be carried on to a plane. Newer models can specifically detect when the user is breathing and increase pressure only when required.

Prices vary widely according to type and although early adjustments are required, it provides a safe and effective approach in the management of snoring and sleep apnoea. These machines help people to regain their energy and improve effectiveness and memory throughout the working day. The benefits can vastly outweigh the initial discomfort.

Medical research for heart and brain

Heart-brain connection

Medical research for heart and brain happens to be an interesting topic. Recent studies concluded, to avoid aging of brain one must keep the heart fit. Though there is adequate evidence to prove such argument, there are comprehensive evidences that correlate with fitter hearts and larger brain volumes.

Cardiac index and brain volume is involved here. Nevertheless, brain functioning isn’t subjected to the heart-brain connection. Irrespective of cardiovascular symptoms, the correlation stands true in all cases.

The heart-brain communication works both ways

We all buy into the common myth that heart only receives signal from brain. Nevertheless, it’s a two way communication between heart and brain. In fact, heart sends more signals to the brain than brain sends to the heart. Not only it sends signals to the brain, it also influences functioning of the latter. From emotional processing to cognitive functioning, it influences every module of brain functioning. Researchers have consistently worked on how large scale patterns in heart activity influences brain functioning.

Heart beat variability during sleep

It is commonly believed that the heart beat rate is steady during rest. But, now researchers have found out heart beat rate is irregular even in resting condition. Heart rate variability is a common phenomenon during resting period. The variability is caused by synergy of both branches of autonomic nervous system. ANS, a part of the nervous system is responsible for regulating body’s internal functions. Vagus or parasympathetic nerves slow down heart rate while the sympathetic nerves accelerate it.

Heart beat patterns and emotions

There are numerous that factors ANS and thereby influence heart rate variability. The factors include physical workouts, breathing patterns and thought patterns. Even our feelings and emotions affect heart rhythm patterns. The patterns will vary with the kind of emotions and thoughts. During frustration, heart rate pattern will be total chaos and during appreciation, it will be in perfect coherence.
