Respiration is a vital sign that is measured frequently in the healthcare setting. Taking this measurement requires no equipment and relatively little time. However, it is a measurement that must be taken accurately, as a change in respiration may indicate the worsening of a patient’s condition.

Measurement of Respirations

Wash hands properly and introduce yourself to the patient. Close the curtain or door to protect patient privacy.
Ensure that the patient is prepared for the assessment:
- Wait five to ten minutes after patient activity.
- The head of the bed should be at 45 to 60 degrees if the patient is lying down.
- Adjust the bedcovers so that you have a clear view of the patient’s chest and abdomen.
- The patient’s arms should be in a relaxed position across their lower chest or abdomen.
- The patient should be calm.
Watch a full breath cycle, both inhalation and exhalation.
Look at a clock with a second hand or a digital clock with seconds displayed. Note the second and begin counting the respirations on the next inhale.
- This can be accomplished by watching the rise (inhalation) and fall (exhalation) of the patient’s hand on their abdomen or gently placing your hand on the patient’s abdomen and watching it rise and fall.
Count the respirations for one full minute. Note if the breath pattern is regular or irregular. Breathing patterns can include:
- Regular: In adults, the average rate is 12 to 20 breaths per minute. Newborns have an average rate of 30 to 60. The average for infants (six months to one-year-old) is 30; two-year-olds average 25 to 32; and children aged three to 12 years, average 20 breaths per minute. The geriatric population tends to average 16 to 25 breaths per minute.
- Hyperventilation: More than 20 breaths per minute (in adults) and deeper than normal.
- Hypoventilation: Fewer than 12 breaths per minute (in adults) and possibly more shallow than normal.
- Tachypnea: Depth of breathing is normal, but rate is greater than 20 breaths per minute.
- Apnea: Pauses in respiration that last for several seconds.
- Cheyne-Stokes respiration: Pattern alternates between hyperventilation and apnea.
- Kussmaul’s respiration: Pattern is regular, but the breaths are unusually rapid and deep.
Replace the bed covers.
Wash hands properly.
Document the respiratory rate and pattern in the patient’s record, and inform the nurse of any rate or rhythm abnormality or significant change from the previous rate and/or pattern per institutional or unit protocol.

Removing Personal Protective Equipment

It is important to follow the correct procedure while removing personal protective equipment to avoid contaminating your skin or clothing. The most common source of contamination in this process stems from improper removal of gloves. Gloves are often the most soiled piece of equipment. To avoid contaminating your skin or the other equipment worn, gloves should always be removed first. Then remove the goggles, gown, and mask, in that order.

Partial Bed Bath

Bathing is an important part of a patient’s health routine. A partial bed bath focuses on bathing sensitive areas that cause discomfort if not cleansed frequently, such as the face, hands, axillae, back, and perineum. Though patients receiving a bed bath are typically confined to the bed, some are able to wash themselves and should be encouraged to do so to promote independence.

Applying a Condom Catheter

Condom catheters are used for men who are incontinent. These catheters are external and are meant to be used short-term and changed daily.

Nail Care (Fingers and Toes) for CNAs

Nail care of both the feet and the hands should be performed as part of the patient’s daily hygiene routine. The status of the patient’s nails can reflect their overall health. Nail issues can also lead to infection that can spread systemically (ex, ingrown nails or fungus). You should never clip a patient’s nails with nail clippers, and always review your institution’s policy about what nail care is allowed.

Putting on Personal Protective Equipment

Personal protective equipment is worn to protect the mouth, nose, eyes, clothing, and skin from unwanted pathogens. In the health care setting, a patient’s condition often prompts the use of personal protective equipment; however, a health care worker is able to wear personal protective equipment whenever he or she deems it is necessary (e.g., during procedures with the potential for excessive contact with bodily fluids).

Lateral (Side-Lying) Position

The lateral, or side-lying, position is often comfortable for patients when they wish to sleep or relax.
