Blood Pressure

Blood pressure is a critical vital sign that measures the pressure of circulating blood against artery walls, and it is measured in two numbers. The first number, or systolic pressure, refers to the pressure inside the artery when the heart contracts and pumps blood throughout the body. The second number, or diastolic pressure, refers to the pressure inside the artery when the heart is at rest and is filling with blood.

Most people don’t know if they have high blood pressure – especially since there may be no noticeable warning signs or symptoms – and therefore the blood pressure must be monitored.

high blood pressure (hypertension), which is a major risk factor for health problems such as heart disease, heart attack, and stroke. In most cases, high blood pressure has no defined cause, and it is called primary hypertension. However, it is related to unhealthy lifestyles such as physical inactivity, stress, obesity, shift-work, pregnancy, etc. It should be emphasized that blood pressure can be managed through diagnosis, lifestyle changes, medication and long-term monitoring.

Blood pressure is categorized as low, normal, or elevated: Low blood pressure is a systolic of less than 100, normal blood pressure is a systolic of 100 to 129, while elevated blood pressure is systolic of 130 or higher.

Oxygen Saturation

Oxygen saturation (SpO2) is another vital sign monitored to evaluate a person’s general health. Oxygen saturation is a measure of how much oxygen the red blood cells are carrying from the lungs to the rest of the body. Normal SpO2 for healthy lungs ranges between 95-100%. For individuals with chronic conditions or lung diseases, it could be lower than 95%.

A low level of oxygen in the blood is called hypoxemia. Typically, an oxygen saturation level lower than 90% is considered hypoxemia, which can be caused by chronic pulmonary diseases (COPD, COVID-19, Asthma, Lung Fibrosis, pulmonary hypertension), heart failure, sleep apnea, anemia, and high-altitude exposure (insufficient oxygen in the air) and medications that suppress breathing control. Common symptoms of hypoxemia include headache, rapid heart rate, coughing, shortness of breath, wheezing, confusion, and blueness of the skin and mucus membranes (cyanosis). 

Oxygen saturation levels can also be used by athletes to understand whether a decrease in performance is a result of altitude changes or ability.

Breathing Rate

Breathing rate is a vital sign that measures the number of breaths taken per minute. The normal breathing rate for adults at rest ranges between 12-20 breaths per minute, but may reach up to 24 breaths per minute for some older individuals.

When inhaling, oxygen enters the lungs and circulates to the various internal organs. When exhaling, carbon dioxide moves out of the body. The breathing rate plays a critical role in keeping the balance of oxygen and carbon dioxide even in the body. If the carbon dioxide level in the blood is high and the oxygen level in the blood is low, breathing rate increases.

Various factors affect breathing rates, including injuries, exercise, fever, anxiety, emotions, mood, alcohol, medication, metabolic issues, and medical conditions. A high or low rate might be the result of an activity, and therefore does not indicate that there is anything wrong.

Monitoring the breathing rate vital sign can assist the doctor in providing medical advice. Furthermore, Athletes may use respiratory rate as an objective indicator of how hard they are working.

Heart Rate

The heart rate vital sign measures the number of times the heart beats per minute. The normal resting heart rate for a healthy adult is between 60-100 bpm. Think of the heart as a pump that pushes blood throughout the body. With every beat, the heart pumps blood containing oxygen and nutrients around the body and brings back waste products. A healthy heart supplies the body with the right amount of blood at a rate proportionate to whatever activity the body is undertaking.

Normal resting rates can differ between people. Furthermore, heart rates are lower when at rest and increase during exercise and can be influenced by factors like, weather, body position, emotions, body size, medication, and use of caffeine and nicotine.

At rest, a fast heart rate may indicate acute health conditions such as an infection, dehydration, stress, anxiety, thyroid disorder, shock, anemia, or certain heart conditions. Moreover, it can predict a long term risk for cardiovascular events. A low heart rate is common for people who exercise frequently and participate in athletics.

Tracking heart rate can provide insight into fitness levels, heart health, and emotional health. For individuals taking medication for cardiovascular conditions, daily heart rate measurements can assist the doctor in advising on the proper course of treatment.

Heart Rate Variability

A healthy heart does not beat at regular intervals as would a metronome; rather, there are variations in time between beat to beat. These variations are measured by the Heart Rate Variability (HRV) metric and they reflect the functions of the parasympathetic and sympathetic nervous systems, the two components of the Autonomic Nervous System (ANS), which controls heart activity. 

The sympathetic system is activated when the body is under stress, causing the heart to beat faster and more regularly, and causing HRV to decrease. The parasympathetic system manages the heart’s activity to help the body reach a relaxed state and to recover from a stressful event. This relaxation response results in a slower and less regular heartbeat and is  indicated by a higher HRV. 

High levels of HRV generally indicate aerobic and general fitness. Athletes may track HRV to adjust their training program. They can learn when the body is being overworked, which often results in a drop in HRV and to learn how fast they recover.  

*Note: There are several ways to calculate HRV, including the one used by the Binah medical team, called SDNN. SDNN is the standard deviation of the intervals between each beat (also called NN intervals). Abnormal levels may indicate risk of stress, risk of cardiac events, oncoming sickness, nutrition and sleep patterns

Sympathetic Stress

The sympathetic nervous system promotes the body’s response to stress, commonly referred to as the “fight or flight” response. When preparing for an emergency, the sympathetic nervous system (SNS) activates numerous complex pathways and components. These physiological activities help to achieve a faster heart rate, breathing rate, and blood pressure. Noticeable changes include blood flow that moves away from the skin and stomach, and is redirected from the intestines to the brain, heart, and muscles, as well as sweating, “goose-bumps”, dilation of the pupils, and a host of other feelings that appear during the stress response.

The sympathetic stress metric uses HRV to calculate the magnitude of one’s stress response, i.e., how stressed a person is. A low score would indicate a relaxed state, while a high score would suggest a stressed state.

Parasympathetic Activity

The parasympathetic nervous system (PNS) regulates the body’s “rest and digest ” response and plays an important role in alleviating stress and promoting recovery. It does so by inhibiting the activity of the sympathetic nervous system and the release of stress hormones, and returning bodily functions to their resting state by slowing the heart rate, lowering blood pressure, reducing muscle tension and restoring regular breathing, digestion and glandular activity.

The parasympathetic metric measures the activity of the PNS and indicates how capable a person is of relaxing or recovering after a stressful occurrence. A low score would indicate a stressful state, while a high score would suggest a relaxed one.

Pulse-Respiration Quotient

The pulse-respiration quotient (PRQ) reflects emergent properties of the complex interplay between cardiac and respiratory activities. The pulse-respiration quotient metric measures to what extent this interplay is functioning normally. A low or high score would indicate that your heart rate and/or breathing rate are disproportionate, which may indicate that both the heart and the lungs are working inefficiently.
